Little Library DIY

We made our own little library! Our little library is not only an accomplishment of a yearslong fantasy, it is also a constant source of joy when people stop by and a great excuse to buy books. I did most of the planning and designing, with construction and style guidance from my parents and my partner Cory and our friend and housemate and generous feudal lady PJ, and fixing from Cory, an actual mechanical engineer, when things broke. I think PJ wanted to buy a professionally built little library, at least at first, but I wanted to do something ill-advised, amateurish, in retrospect possibly manic, and from the soul and also to use a dremel for the first time in ten years.

Our little library is painted black and the books have a sometimes spooky tint, because we live in a not-yet-painted-black house that may or may not have its own soul (and if it does have its own soul, or a visiting soul (other than our visiting souls, of course), it is absolutely a spooky one) across the street from a graveyard in Salem—which of course means that most of our neighbors and subsequently most of the visitors to our little library have died. Spooky books are often also joyful books, and hopeful books—but sometimes just spooky.

This is a blog post about how we made the library/libraries. Spoiler alert, it ends up looking like this:

Ingredients

Here’s everything I bought to make the library:

  • A reasonably-sized waterproof bathroom cabinet, to serve as the larger library—we painted it black, but this one was originally white, which already looked very nice as a potential library
  • A narrow waterproof bathroom cabinet, to serve as the small library—this one is dark brown, since it was closest to the intended black, but it also comes in white
  • A five-pack of 8×10″ plexiglass, to serve as the windows
  • Durable, waterproof plastic file folders, to serve as the roofs—in black since our library is black, but you can get colorful ones instead
  • Mounting tape, to attach the windows and the roof
  • Black outdoor paint, to paint the cabinets our preferred color, which was black—but you can choose a different color, or you can choose to not paint your libraries at all
  • Barrels to plant your libraries in—I bought these fancy wooden bucket barrels (18 inch, 15 inch, and 11.5 inch diameter, one for each library and the smallest destined for flowers). I like them a lot because the real wood and its smell and its texture and the metal handles were important to me because smells and textures are important to me in general, but they are expensive; cheaper, perfectly acceptable, possibly more durable plastic bucket barrels exist, and different sizes and shapes and quantities of the wooden ones—this is the fun part; you could even get this weird wishing well planter I’ve been trying to find some excuse to buy (but I have nothing in particular I want to do with it and nowhere in particular I want to put it) and stick a library in it, which is what I would probably try to do if we decided to add a third library

And here are things we already had that we also used:

  • A dremel, to cut out interestingly shaped window-holes
  • A sturdy pocketknife, to cut the plexiglass to fit the window-holes
  • Variously sized small pieces of scrapwood, to attach the roofs to and to make lock-type turning mechanisms so the doors don’t blow away
  • A drill and drill bits and screws, to attach the roofs so they don’t blow away and to attach the lock-type turning mechanisms
  • Lots and lots of rocks
  • Dirt
  • Flowers
  • A very strong glue to fix things when they break, like JB-Weld or Gorilla glue

And some things I bought to put in the library once we built it:


Methods

Here’s how we built the library.

First, I assembled the smaller of the two shelves. (In retrospect, I should have waited until after dremeling the doors, but it worked out fine.)

The shelf fit nicely in its intended bucket, as intended, with some books in it.

I dremeled windows into the doors of both the small shelf, which was easy because I just sliced the spaces between the horizontal gaps, and the larger shelf, which was more challenging. I tried to make the windows large enough that you could see in and see the books. I considered adding more windows to the other sides of the shelves, which you could if you wanted to, but we decided on just the doors.

(Does what I’m doing make you slightly uncomfortable? It probably should. I have no training in this except Science Olympiad in high school.)

I also reoriented the doors of the larger shelf to open in opposite directions because that is more interesting.

Here is how the larger shelf looks, dremeled and assembled:

I like how the large shelf looks as a white shelf, and white might be a good fit for a different project, but we had a whole vibe planned so it had to be painted black. I think it turned out nice and dramatic.

I measured and cut as large rectangles of plexiglass as would fit across each of the doors of the small shelf, covering the windows I had dremeled in (and which had partly already existed before my dremeling). I attached the plexiglass to the doors using mounting tape, which apparently is used for cars so it is probably good enough for this purpose as well.

I cut small straps off a skirt belt I didn’t like and curled them into door handles for the larger shelf, and attached them using mounting tape as well.

Then I cut and attached the plexiglass windows on the doors of the larger shelf—big rectangles covering both the big window holes and the little door handle holes.

Here’s how they turned out, with books inside:

To make a roof, I decided to use file folders, supported by wooden blocks that had been used to deliver furniture. Here is what that brainstorming looked like.

I painted the wooden blocks black and used mounting tape to attach them to the libraries.

I wanted the roofs to be waterproof, and black, so I ordered black plastic file folders and used them as roofs, attached also with mounting tape. Cory told me that when he was improving on this idea later he mentioned my use of plastic file folders as roofs to a coworker, who said that non-engineers sometimes come up with creative ideas to engineering challenges that a person boxed in by an engineering education might not have come up with. A very kind compliment.

They turned out quite nice, I think. Very witchy and spooky.

Here they are in their buckets, outside. We reserved the bottom part of each shelf to fill with rocks so that the libraries would be heavy and more or less sturdy. The shelf comprising the smaller library is actually upside down—the now-bottom shelf used to be the top shelf, intended to store toilet paper.

We bought flowers to plant in the buckets alongside and around the libraries:

Here is Cory planting the flowers. We planted the flowers on the sides and filled the rest of the space in the buckets with dirt. The smaller of the shelves is entirely dedicated to a flower we saw a lot of bees on, which seemed like a very good sign.

Here is how they turned out, after sunset and full of books. Very spooky and cozy:

We bought a ton of books to fit in the libraries. Here are some of the books we bought:

We dedicated the hall window overlooking the libraries to the books we plan to add to the libraries. Here they are at various moments. We ended up moving them from the windowsill to a dedicated shelf under it because there got to be too many.

PJ officially registered our libraries. Here are the fancy materials they sent us, including a little plaque:

Here are the libraries with their plaque. PJ also got a gorgeous flag and a wooden sign and little reading owls sculptures.


Here’s where dreams meet reality, and it gets a little sad—but happy and better afterward. Around Halloween we had a very bad windstorm and everything that could blow away did. The library flag blew away and we found it somewhere down the street. The roof folders blew away and we did not find them. The skeleton hand you can see in the mulch also blew away and we found it later near the graveyard (maybe it was trying to return home). The fence came down, thankfully missing the libaries.

There were two problems we kept running into: one was wind and the other was rain. The roofs kept blowing away, and mounting tape was just not doing the trick. And the doors kept blowing open, letting in rain and getting the books soaked. Twice a door was blown open hard enough that it broke off.

Cory is an actual engineer. He made nice wooden door locks to keep the doors from blowing open and drilled them into the libraries.

Cory also fixed the broken door with superglue.

Finally, Cory added additional wooden supports for the roofs, and drilled screws through the roofs into the supports. No more flying away.

I’m very grateful to Cory for supplementing my—um—creativity with thoughtful and weather-aware actual engineering. Here’s how the libraries turned out, with their improvements:

And here they are now:


Little Libraries of Centre County

The past two weeks I was home in Pennsylvania for the first time in two, maybe even three years. All the trees I remember got taller. Even our houseplants got taller.

Last time I was home I don’t remember seeing many little libraries; I don’t remember seeing more than one. Since then they seem to have cropped up like mushrooms (or mushrooms/suburban housing developments/suburban housing developments made of mushrooms)—all shaped like little houses, all clearly created and curated with care and love, all unique. The libraries I visited multiple times had different books each day—and the books themselves seem to be very thoughtful collections.

There are, of course, many more little libraries I did not see than there are little libraries I did see. And some of the ones I did see were not on any map—which means there could be surprise libraries on any street we could step into on a meandering walk like those we had together in the evenings this June, and even making a thorough scavenger hunt of it would not guarantee I found them all. Some kind of commentary, perhaps, on more generally living life as a whimsical adventure.

Here are the little libraries I got to visit.


A little library in the Arboretum. The Arboretum was just starting out when I started college and has now blossomed. We had class field trips to the Arboretum in my writing classes during my year at Penn State. This little library is the one and only little library I remember seeing on a past visit:


A little library on a walk near our neighborhood. This library has adorable decorations inside: little hanging pictures, including of cows in a field, which is a not-uncommon view here. The book selection changed from day to day, and on one day, a sticker collection appeared:


A little library in the park where I and my friends used to play hide-and-seek tag after dark, and past which I used to bike on my way to school in the mornings, past little lakes of mist settled in the little valleys between the tiny hills in the park:

I picked up my next book to read at this library, and a book heart sticker at the library before it. The book heart sticker is now on the first page of my todo list notebook:

I picked up Gameboard of the Gods by Richelle Mead, which I am now reading alongside Small Gods by Terry Pratchett. Because circumstances necessitated comfort reading I took a break from Small Gods to reread Bridget Jones’s Diary and Bridget Jones: The Edge of Reason (Bridget Jones’s Diary volume 2) by Helen Fielding, which are two of my favorite books. But now I am on from novelized late-90s feminism/Pride and Prejudice retelling to fictionalized polytheism. Along the same path I am also listening to Old Gods of Appalachia, which is spooky and excellent (“…an eldritch horror fiction podcast set in an Alternate Appalachia, a world where these mountains were never meant to be inhabited. This world feels eerily similar to the hills and hollers we’ve grown up with, but there are some tell-tale differences. Names of towns and counties may be altered. Historical events slide forward or backward in time. And then, of course, there are the monsters…”).

A little library on the drive to a friend’s house (I nearly dove out of the car to get a better look and take a photo). This one has a gnome and little red mushrooms, and I really like the trellis up the side of the house. It feels like maybe the gnome lives in this house, and it is his personal library that we are disturbing; very kind of him to invite us in:


And another little library in that same neighborhood, right along a bike path. This neighborhood is very modern, with unique and unusual homes, some built into hillsides; this library matches them nicely:


A little library near our high school, on the walk we used to take home from school:

This library is in a park I used to bike past multiple times a week, depending on the path I took to school or home from school, and yet I never particularly noticed—and the park is huge! and gorgeous.

You might notice that by the time we got to this little library, it was sunset. The walk home gave us these gorgeous spooky-peaceful Pennsylvania views:


Another little library near the school, on the same walk, a few blocks out of the way, in a beautiful neighborhood I’d never walked through before—this library is more of a castle, with stepping stones, a little garden with labelled plants, and flowers painted into the inside walls:


A surprise little library we stumbled on, also on that walk. This little library has a cozy reading chair inside, and a door nicely sized for a creature who might use that chair. Very cute, and very sturdily and creatively constructed, with a gorgeous and modern glass ceiling and glass walls and therefore plenty of sunlight for the cozy creature(s) to read by:

There is a convenient door at the base of the library, which means there might be an exceptionally tall spiral staircase up to the reading nook.

We came back a few days later and the Pride flags had moved up:


A little library on another walk, on the way to go see a new housing development that was just being planned (and protested against) when I was last home. Years ago, the new housing developments were all very strange: some of the roads had been made, but not all of them, and none of the buildings, but the busses were already running, circling around nowhere, picking up no one. Now this one is a bizarre modern village with lights in the windows and people living their lives and a steep drop into the hills.

This little library is a ways away from the new neighborhood, but it was on our winding walk there. It has a cat in a window:

This walk gave us these gorgeous spooky-peaceful Pennsylvania views:


A little library by an elementary school. My dad thought there might be a library there and stealthily led us to it on a walk, and indeed there was a library there; a very happy surprise. The color and in particular the roof are very elegant and cute:


A little library we intentionally walked to, but were startled to find empty. It is by a football stadium near campus; the semester is over and the football stadium is empty, so maybe that is why the little library is empty. It also has a little free necessity box next to it:


A little library in Shaver’s Creek, next to the environmental center, surrounded by forest. This little library is next to a very pretty little artificial pond with a bench next to it. We saw a turtle swimming in the pond and we saw two frogs:

Here is what Shaver’s Creek looks like—the world surrounding this particular library:


Finally, a little library my brother’s friend Maya sent to my brother Max and my brother Max sent to me when I was on my way back to Massachusetts. I love its long shape and asymmetrical roof:

The plane ride back to Massachusetts was the most beautiful and the most bittersweet of recent memory. Here are my views on the way home:


The Free Book Cycle, Crayons, and Answering Reader Discussion Questions for Don’t Look Behind You by Lois Duncan

I blogged previously about my love for our neighborhood’s little libraries. If you are like me, and you ever feel lonely or disconnected, then maybe you, like me, could benefit from buying and donating your favorite books as a valued part of a good de-lonelying. You get to experience the fun of shopping, the anticipation and thrill of getting books in the mail and finally holding them in your hands, maybe the comfortable adventure of rereading a favorite story, a lot of nice walks with a nice destination, and finally the hope that you’ve given a favorite piece of yourself to someone else who really loves it and that that part of you might be out there making the world better for them. If you can afford it (and it’s cheaper than you might expect), I recommend it.

This time, I also bought a big pack of crayon boxes, because I love crayons and I think I would have loved to find a box of crayons as a child, especially alongside a great book, and I wrote little notes in the books and in the crayon boxes, including a favorite inspirational Neil Gaiman quote.

As much as I give I apparently also take. Here is our добыча from Salem’s Free Book Day on April 10th. All or at least the vast majority of these books will, of course, eventually make their way back into the free book ecosystem.

So far, I have read Finlay Donovan Is Killing It, which is about a writer writing fiction about (and definitely not engaging in, certainly not for substantial supplemental income, and absolutely not as research for her next book) murder for hire; The Messy Middle, which is not about murder for hire but is about working through the middle of any other kind of long and difficult project (something like, perhaps, a PhD); and My Name Is Awesome, which is about naming things and is really more of a pamphlet. My partner Cory is reading Company of Liars. Happiness, happiness, happiness.

One of the books I bought for my little library donations was a favorite from a previous life, Don’t Look Behind You by Lois Duncan, which is a fictional suspense story about a family that goes into witness protection. Growing up I really, really, really loved anything and everything by Lois Duncan. I still remember the exact shelf in my middle school library where Lois Duncan’s books lived. I checked that shelf every time I got to go to the library to see if there were new-to-me books that had previously been checked out. Whenever I did get a new Lois Duncan book I remember not being able to sleep until I was done reading—by flashlight under the covers (worth the vision loss? maybe), promising my dad every time he noticed the light under the door that I’m of course going to sleep (absolutely not, but worth the sleep loss, I think). It was delightful to reread.

When I finish a book I enjoyed I usually read through to the acknowledgements and, if it’s a teen book, the reader discussion questions. Just for fun, just this once, I decided to actually answer them.

1. Until April was called out of class, she didn’t know how much trouble her dad was mixed up in. Do you ever wonder if your parents are hiding secrets from you?

What an odd question to ask your middle school English class: “Children, are any of your parents secretly tied up in anything suspicious? Maybe an international drug cartel? Please, speak clearly and slowly into this microphone.”

(And no, I don’t. But I also believe that if my parents do keep secrets from me it is healthy and okay, because we’re all adults and we are all allowed our own private (non-crime-related) lives.)

Discussion questions are off to a weird start.

2. Is April’s life back home really as perfect as she makes it sound? Explain.

April has a boyfriend, a nice house, a sport she is both good at and deeply invested in (a helpful combination, to be both good at something and interested in it), friends, and a family that loves her. That sounds great. I think that’s a nice life.

3. Lorelei and April’s mom are very different. Do you know people who are very different from their parents? In what ways are you different from your parents?

I really enjoy stories about women in a family, especially women from multiple generations of a family. There is so much that goes into a multigenerational family relationship—your expectations of each other through the different stages of life as each of you changes, how that relationship changes into adulthood and old age, the childhood scars and fears that each person brings in, the unexpected things that bring you closer or farther apart. I love how Meg Wolitzer explores family and friend relationships over time, especially in The Position and The Interestings, and I really like Gilmore Girls for the same reason. The first time I watched Gilmore Girls I was closer to Rory’s age; Rory was my main character and her relationship with Lorelai was the most interesting part of the story to me. Now that I’m closer to Lorelai’s age, Lorelai has become my main character and her relationship with Emily and her professional growth are the most interesting parts of the story to me. I wonder how my experience of the show will change if I rewatch Gilmore Girls again in the future, maybe when I hopefully someday have my own kids.

My mom, my maternal grandmother, and I all have the same voice—I guess it is passed down on the maternal line. My grandmother is a bit more high-pitched (she sometimes sets of fax machines), but all three of us have very expressive voices that can’t be distinguished from each other over the phone. Otherwise the three of us are all very different, and those differences are magnified by us having lived through very different times and experiences and having grown up in different cultures. Exactly as we should be. I think we complement each other well.

4. When April listened in on Max’s call to Jim about the threatening letter her dad received, she decided not to tell her mom. Did she do the right thing? Why or why not?

I definitely think that in a scary story it is generally very important to the protagonists’ survival that they openly and immediately communicate all scary-story-relevant information. So no, not the right thing.

5. April complains that her family’s time at the hotel with Jim is boring. What would you do if you were stuck in that situation? Would you be bored watching TV all day, with no friends to talk to?

This was a very interesting book to read at this time. In the book, April is trapped indoors by the witness protection program. In the real world, we’ve been isolated and to varying extents removed from our lives by the pandemic. (I’m not sure which sounds more fictional.) Based on the past year, I know that I would watch a lot of TV but that I would not watch TV all day. I would probably spend more time on the balcony, or whatever outdoors I could reach. I would get more books (clearly) and spend as much time as I could with them—and maybe some plants, too. I would miss my friends and family a lot.

6. Since she was quite happy with her old life, April is reluctant to start a new life in the Witness Security Program.
Other people might find it exciting to start with a clean slate. Have you ever fantasized about starting fresh in a place where no one knows you? If you could reinvent yourself, what would you change? Where would you move?

I, like April, have a lot invested in my current life and have worked hard to build many things that I care about—I wouldn’t want to start over. A change sounds appealing, but not a clean slate, except perhaps the kind of clean slate that comes from finishing projects and getting to start new things that I currently can’t even imagine. I do think it would be fun to do something new—not too new, but a little new, having finished previous projects to my satisfaction and taken some time to read and think. That kind of clean slate sounds nice.

7. If one of your friends disappeared without warning with her entire family, what would you do?

I would assume that my friend got deported. I tend assume that my friends are not going to be deported, but I have been wrong in the past. It is very sad when something like this happens.

8. When Larry first invites April to the movies, she’s worried about being faithful to Steve and doesn’t want to go on a date. Later she finds out that Steve hasn’t waited for her. Taking the situation into account, would you wait for April if you were in Steve’s shoes? How long could you wait without even knowing what happened to her?

I’m not in high school, and my partner is my partner of almost a decade—if he disappeared to go into witness protection and I did not even know where he disappeared to, my world would crumble. For that reason I imagine we would disappear together, though I also wouldn’t want to leave my family so maybe we could bring them too.

If I were me from high school and my boyfriend of perhaps several months moved across the country without saying goodbye, I don’t know that I would look too far past the surface of the situation. Boyfriends move, and while a cross-country move is a lot to hide, sometimes people hide things they aren’t thrilled about. I would be upset but, in high school and as my high school self, I’d probably move on quickly.

9. April really loves playing tennis, and her skill is a big part of her self-image, so she takes it hard when she finds out she can’t play on the team. What interests, hobbies and talents do you think define you as a person? What would you be unwilling to give up in a similar situation? Are there certain things that are so important you could never sacrifice them?

I think any means of creative expression, especially one you are good enough at that you are reliably able to commit a piece of yourself to it and feel truly seen by other people through it, becomes an important part of the self. I can’t imagine tennis being that kind of expression for me, but I do not play tennis. I am especially sympathetic to April’s mom, who had built a writing career she was proud of and now couldn’t write, not even under a pen name.

10. When April presses her dad for the reason he put the family in danger, he says, “The real truth is, I wanted to be a hero” (p. 120). He explains that he’s never felt important in his life, and this was his big chance. Do most people want a chance to be heroes at least once in their lives? Why or why not?

I think everyone wants to feel that they’ve made a positive impact in the world, preferably in some way that is personal and validating. This scene was a very valuable part of the novel. I don’t know that I would have sympathized with April’s father without it.

I think this question ties in to the previous question. To April, her legacy was tennis. To April’s mom, her legacy was her writing. To April’s dad, his legacy was what forced the family into witness protection. No one got to keep their legacy except April’s dad, and living his legacy stripped the rest of his family of theirs. That’s not how it should be—families should support each individual’s independent life and work and whatever mechanism they’ve found for sharing themselves with the world.

11. At the end of the book, April seems to come to terms with her new life. What would you miss most if you had to start over? Who would you most want to be able to see again?

At some point in The Messy Middle (from my Salem book haul) the author says that we should value our projects and jobs and situations and the people around us not only by how much we want them now, but by how much we would want them and fight to get them back if we lost them. For me, that’s a lot.

I would miss my friends and my family the most. I would miss my home—both Cambridge and central Pennsylvania. There is something very comforting in the particular plants I’m used to seeing around me, and in the clouds and the rain and the hills and the forests. I don’t think I could comfortably live for very long in a desert or in a warmer climate or in a very different part of the world. I don’t think I could live at all without my family or my partner.

And of course I would miss the life I’ve built for myself and the hope I have for it. I would miss all the little parallel tracks I’ve built, and I would always wonder where they would have led if I’d gotten to stick around to see them.

—But I don’t have to miss it, any of it. It’s all mine.

To end, an inspirational reminder to myself and to anyone else reading this, because art is important and uplifting from both the receiving and the creating side of it—

Little Libraries

It is getting cold and there is a pandemic and sometimes it is lonely. If you would like to do something nice, here is a nice thing you could do that feels extra good because it is also putting a bit of your soul out into the world to share and for people to love.

A lot of people in our neighborhood and surrounding neighborhoods and towns have been putting up little libraries. They make me very happy. They are all decorated and in pretty shapes—often house shapes, which is delightful, but we have also seen some carved into stone walls and some are simple large plastic bins with a library label. I don’t keep track of where the libraries are, and the books are not organized or distributed in any particular way, which makes stumbling on them and looking into them a special and surprising experience. I’ve found some unexpected books I don’t think I would have otherwise read. Finally, I really enjoy the experience of browsing in a library, of knowing the layout of my favorite shelves and what books live there and physically holding the books and reading the summaries on the back and feeling the pages between my fingers while I read a bit before checking a book out. In elementary school at AJLA we used to have special days when we got to go to the library as a class, and we got an entire chunk of dedicated time to just browse. I think we had a limit to the number of books we were allowed to check out at one time, because I used to get special permission to visit the library extra times during the week if I finished all my books and finished my classwork, and it was always very special to me to get to go. I still remember my room and the layout of our house from when I was that age, and I also still remember the school library and where each section was located and what books were on each level of my favorite shelves (I was especially obsessed with Lois Duncan). We live right next to a library now but I haven’t had the experience of checking a book out in person since the library switched to virtual ordering for the pandemic, and I miss it, and the little libraries have given it back to me.

I took photos of some of them to share with you:

Cambridge in general often has lots of books out on the sidewalk for people to browse and take:

You might have noticed that a lot of the little libraries are associated with Little Free Library, but not all of them are, and all of them are good.

Because the pandemic has made getting my favorite books a little more challenging, I’ve faced the reality that the local library is not indeed a massive extension of my personal book collection (nor my home office). In other words, I finally got around to buying my favorite books. I bought most of them used, to replicate the library experience as closely as possible (some of them are actually from actual libraries), and since used books are so cheap I bought several of each. I kept one of each book, and the others we put in a particularly empty little library in a particularly well-used public park. Here is round 1:

And here are rounds 2 and 3, coming soon:

It is a small nice thing to do, but it is very special to me, and I think I will be doing this somewhat often (especially since shopping and bidding on things are their own fun). It is a very cozy thought that at any moment today, someone might be discovering one of my favorite books and maybe it will become their favorite book, too—and maybe they’ll keep the book and reread it, or maybe they’ll put it back and someone else will enjoy it, too.


Here are some nice photos from throughout the past few years, some pre-pandemic, mostly mid-pandemic, in no particular order:

Infectious Disease Reading List: My Qualifying Exam Experiences, Advice, and Syllabi

Every PhD student I talk with seems to have a different qualifying exam and a different qualifying exam experience. My department, Organismic and Evolutionary Biology at Harvard, has a very flexible and customizable quals, in line with the overall very flexible and customizable PhD program. Our qualifying exams usually happen in the second (G2) year, and consist of the following parts:

  • Three committee members, in addition to your advisor, one of them (not your advisor) Chair of the committee—all available at the same time, all in the same room (or zoom room). This part was trickier than I expected. The committee does not all have to be from the department, which helps. Connecting with professors I had already had excellent and productive interactions with helped. Asking for broad availability before sending out possible exam times helped. Booking the room well in advance helped (but did not end up being necessary in my case).
  • A written dissertation research proposal describing the work you plan to do during the rest of your PhD. I have been told that a lot of people end up deviating from the proposal. My proposal consisted entirely of projects I had already started and am committed to finishing. Even so, I am already doing work I could not have even imagined when I wrote my proposal, even though I wrote it something like seven months ago.
  • Three syllabi of courses you think you are qualified to teach, on varying topics and of varying levels. This is open ended and different from what I usually do and (I think) a lot of fun.
  • An oral exam, up to three hours long, consisting of two parts. First, you present and answer questions about your work. This part is (I think) a lot of fun. Then, the committee asks you questions, guided but not constrained by your syllabi, to find the depth (or shallowness) of your knowledge. This part is (I think) a lot harder and less fun.

I passed my quals in the spring, during my G3 year, on Monday, April 13th (like Friday the 13th but worse, because it’s a Monday). We’re required to pass sometime during the G3 year, so I just slipped under the radar. (I had also scheduled a back-up time a few weeks later in case I failed, but I did not end up needing it (!!!!).) April 13th was at the very end of the very start of the pandemic in the United States—my quals were virtual, over zoom. I had originally timed the exam to be right before my mom’s birthday and just after my dad’s and brother’s birthdays, and planned to go home to Pennsylvania right after, hopefully accomplished and with a weight off my shoulders and with full focus on family. Of course that did not happen, and I haven’t seen my family since spring break in March. Instead, I got back from my own birthday with my family over spring break in Florida to a lockdown, thinking it was temporary, and focused fully on quals prep.

I wrote my dissertation research proposal first, with three chapters covering my three in-progress projects (and one tiny transition chapter-ish section covering a relevant smaller completed project). These wound up being 1,970+510+2,245+2,628 = 7,353 words not including references and took a lot longer than I expected, largely because the writing required a lot of reading. I then compiled my syllabi. I got carried away and added far too many papers; I ended up (by request of my committee) sending another version with key papers highlighted. This sequence of events was bad, because it allowed early tasks to steal preparation time from later tasks; it was also good, because it allowed me to work on just one thing at a time, which (I think) I am better at than I am at multitasking. I give a lot of presentations at work, so my slide deck covering my research was largely already ready—which meant that in the weeks leading up to my exam I was able to focus almost entirely on reading the papers on my syllabus.

The exam itself was fine. I took it sitting on the floor between the couch and the coffee table in our living room, with my computer on the coffee table and cups and cups of water and coffee just offscreen on the floor next to me. I was very nervous leading up to the exam and didn’t sleep, which was a mistake. My presentation of my research was excellent, I think, though (not surprisingly) I was not able to get to everything I wanted to talk about and we exceeded the allotted time. The oral exam was a weaker point. I did not know the papers on my syllabus well enough to answer pointed questions about the material anywhere near as well as I would like, even though I had read every paper. I was very nervous, and made some embarrassingly dumb mistakes. In retrospect, for both the presentation and the syllabi, it would have been better to give myself less material—to go deeper into the material on the syllabi and to go less deep into my own work, at least for the presentation (not the written proposal).

When I entered the time crunch of the last few weeks left I put together a spreadsheet tracking my progress and timing of remaining work. (You update the count of papers you’ve read in the “done” columns and everything else fills in automatically.) I make a spreadsheet like this one every time I have some work to do that is both time pressured and easily quantified, which is rarely the case in grad school (except for quals prep) but was usually the case in undergrad. I started making these kinds of spreadsheets a few weeks into freshman year; my friend Mika taught me pretty much immediately after we both arrived on campus. It is motivating and reassuring and probably also a method of procrastinating. I’ve attached a version of my spreadsheet below, with Halloween set as the deadline, in case you would like to go nuts in the way I particularly like to go nuts and use it as a template or inspiration:

All in all I spent about exactly a month on full-time/overtime quals prep (pretty much quals prep and sleeping (probably not enough sleeping) and very little else) from the middle of March to the middle of April. I think it was good for me to constrain this chapter of the unending project of self-improvement and mind expansion—but if I could go back in time, I would have started compiling my syllabi and reading the papers on my syllabi during the first year of my PhD. Some of the texts on my syllabi are material I read and learned at the start of my PhD, but because I chose to also include a lot of material I wanted to know well but didn’t, there was a lot for me to read leading up to the exam and I am not satisfied with how well I absorbed some of it. Reading just one or two papers a week spread out over a year would have probably resulted in far better retention and learning, and would have allowed me to dedicate more time to getting everything I could from each paper. At the time I was intimidated by the process of putting together my syllabi, but I didn’t need to be. Organizing my favorites of the papers I was already reading into vague themes would have been a good enough start to later retrofit to the desired format.

I have been told that some students dedicate an entire semester to preparing for quals. I don’t think I would like to do that (and if the pandemic hadn’t paused my primary project I probably would have continued to try to multitask and continue working on research—which probably would have ended badly for my qualifying exam, though who knows), but focusing entirely on reading and writing for a stretch of time was very productive for me.

I learned a lot, both about my current projects while preparing my dissertation research proposal and about what kinds of work and tools are available to me in the field more broadly while preparing my syllabi. As I expected, having to write out the current and future directions of my current projects and having to read deeply enough to write every sentence with full truth and confidence forced me to gain a much, much better understanding of my own work and of the adjacent literature. What surprised me was that when I returned to my research after my qualifying exam, I returned with a lot of clarity of a sort I hadn’t had before. I knew where I was and where I was going in my current projects. I also found myself coming up with exciting new project ideas at a rate and of a quality (if I may say so myself) I hadn’t expected from myself at this stage of my career; quals definitely caused a leap in my ability to think like a scientist.

The document itself is also helpful as a compilation—I rather frequently refer back to my project proposals, my syllabi, and especially the references at the end of each project proposal. My strategy in undergrad and at the start of grad school was to do the science first, then write only when the science was done. Now I am trying something new and writing the paper as I go, and I find that so far it has made the work far more focused, informed, and efficient, and has give me a way to identify (and hopefully fix) problems and gaps in my work well before I try to build anything on them.

To sum up, here is my advice to anyone getting ready to prepare for their qualifying exam:

  • Start identifying and reading papers for the exam well in advance, even before you actually start officially preparing for the exam—a little at a time. Amortize as much as you can of the paper reading part of the work.
  • For every paper you read, put together a few sentences summarizing the key takeaways from the paper. Review your list of papers and summaries in the days leading up to the exam.
  • I found quals to be a great opportunity to learn things I did not know but wanted to know. You can fill your syllabi with material you know well, material you want to learn, or a mix. Consider what you want to get out of the experience and plan from there.
  • When scheduling the test, first ask your committee for broad swaths of time (weeks or months) that are or aren’t good and for any recurring commitments when they are always busy. Then send out a poll with specific test time options. I initially sent out a poll with five timeslots, and then when none of those worked I sent out another poll with ten additional timeslots. I had access to two of my four committee members’ calendars, which helped. I also found it helpful to allow committee members to give each time slot a score from 1 to 5 (5—extremely convenient, 3—I can make it work, 1—doesn’t work for me) rather than just saying yes/no/maybe, which made it easier to work with potential scheduling conflicts. Here is what my first scheduling form looked like:
  • Send out and ask your committee to reserve time for not one, but two three-hour timeslots for your exam, several weeks apart. This way, it won’t be as hard to reschedule your test on short notice if someone has an emergency or a conference or an unexpected vacation or speaking opportunity. And if you fail your test you have another one already lined up with time to prepare for it.
  • Don’t worry about fitting everything into your presentation. If you’re anything like me, you should make the presentation itself shorter than you think it should be—if you have more slides, then you can have plenty of hidden slides ready in case they come up in questions and discussion.
  • There will be questions you don’t know the answer to. Hopefully you are able to answer the shallower, easier questions before reaching something you do not know.
  • Have a nice, efficient stress-relief activity that doesn’t hook you into spending a lot of time on it. I almost never played video games until studying for my quals and for some reason occasionally playing Animal Crossing elevated rather than decreased my productivity, which is not something I would ever have expected.
  • Get plenty of sleep the nights leading up to the exam itself.

What follows is my three syllabi:

  1. Evolutionary Perspectives on Human Disease, which is meant to be an introduction to the immune system as it appears throughout life (in humans, in animals more broadly, in plants, and in bacteria), a not very deep look at disease (infectious and otherwise) across life, and interactions between and co-evolution of infectious agents and their hosts, especially when the hosts are human (but also, briefly, when the hosts are bacteria), culminating in the evolution of the placenta.
  2. Microbial Inhabitants and Infectious Agents of the Human Body, which is a sweeping view of past outbreaks and epidemics, culminating in the current COVID-19 pandemic, as well as short visit to some of the microbes that we more happily coexist with.
  3. Introduction to Data Analysis Methods for Biological Inference, which covers everything from experimental design and statistical tests to multivariate models to GWAS and PCA to how sequencing works and metagenomic sequencing and genome assembly and phylogenetic trees, culminating in an exploration of how genomic sequencing can be used to track and react to infectious disease outbreaks (which is one of the things that I work on).

I tried to design the syllabi as if I were actually teaching these courses—and I would actually be very excited to teach them. They encompass, I think, most of what I know that is most relevant to my research, including a lot of things that I did not know until I put these syllabi together, found gaps in my knowledge that I was not satisfied with, and filled them. (I would also like to teach creative writing, but alas.)

You might notice that the readings include both actual papers and science journalism, in some cases science journalism about papers that are also included. (This actually came up as a question during my exam!) Including both was a very intentional choice: science journalism—specifically, Popular Science and then MIT Technology Review—was the first context in which I read about and got excited about research. I still get most of my science news from popular science journalism, especially in fields that I am curious about but am not doing research in. My hope, if I were actually teaching these courses, is that offering both research articles and popular science would

  1. allow students who are just starting to learn about infectious disease to engage in the class, hopefully leading to increasing comfort and a transition to the primary literature as the semester goes on,
  2. give students who are confused about or lost in a paper a way to get untangled (and teach students to seek out ways to get untangled), and
  3. show students some of the many different ways of writing about science, and show them good (and possibly bad) examples of how to communicate both with their peers and with a broader audience.

You might also notice that I put these syllabi together in March—some of the work on COVID-19 is already out of date.

There are two books I reference a lot, because I like them a lot, that I highly recommend—

Regression and Other Stories (Analytical Methods for Social Research) by Andrew Gelman, Jennifer Hill, and Aki Vehtari:

We used Regression and Other Stories in OEB 201 (Introduction to experimental design and model building for ecologists and evolutionary biologists) with Professor Lizzie Wolkovich my first semester of my PhD. The class and the textbook were both extremely useful and enjoyable—definitely one of my most efficient and relevant learning experiences. Our version of the textbook was an earlier draft, spiral bound, years before it came out—we got to read it early and we got to contribute feedback that went into the final version, which I thought was a fun and special experience and a neat way to feel connected to a work that I greatly enjoyed reading. My copy is very, very dog-eared and highlighted and covered in notes and thoughts in every margin. I refer to it often whenever I need to do any modeling or think about experimental design.

Zoobiquity: The Astonishing Connection Between Human and Animal Health by Barbara Natterson-Horowitz and Kathryn Bowers:

Zoobiquity completely changed the way I think about the human experience and broadened my view of human disease—which was extremely valuable because human disease is the focus of my work. I got to be a Teaching Fellow a few years ago for three sections of HEB 1328 (Evolutionary Medicine: Comparative Perspectives on Medical, Surgical and Psychiatric Illness) with Professor Barbara Natterson-Horowitz. The lectures largely followed the book, which is nice because it means you can get a good part of the learning by reading it.

Evolutionary Perspectives on Human Disease

Immune systems, infection, and inherited disease across life.

This is a lecture-based class introducing the human immune system from a comparative perspective, along with some of the diseases our immune systems help us fight or can cause. We will learn about immune systems across life, in bacteria, plants, humans, and non-human animals—and how comparing immune systems allows us to better understand zoonotic transmission of disease. We will then look at some examples of infectious disease and inherited disease in animals and plants, and how animal parallels of human disease have helped us solve our own, human mysteries and make strides in medicine. Finally, we will look at how pathogens and their hosts impact each other’s evolution, and how human evolution has been impacted by disease.

We will meet on Tuesdays and Thursdays. Every week, you are responsible for reading your choice of two of the other listed texts closely enough to be an expert, and emailing me one generous tweet-length response to each text that you choose (≤250 words each). For the last 15 minutes of each lecture, I will display two responses on the projector and we will discuss them as a class. Highlighted texts are strongly recommended.

In lieu of a final exam, you will choose your favorite of your peers’ “tweets” that we discussed in class (not your own) and use it as a jumping-off point to write a 1,000- to 2,000-word response drawing from the texts and from class discussion.

By the end of this course, you will have a broad understanding of immune systems and disease across life, and (hopefully) the value of knowing it all.

Microbial Inhabitants and Infectious Agents of the Human Body

Overview of common viruses, bacteria, and eukaryotes, pathogenic and not, and a history of disease outbreaks.

This class is an introduction to our neighbors in the human body: common viruses, bacteria, and eukaryotes—helpful, neutral, pathogen, or some combination of the three—that we share our bodies and our lives with, and which have profound impacts on both.

At the end of this course, you should have a broad understanding of the kinds of microbes that live in the human body and how they affect our health. You should also have a perspective and opinion on disease outbreaks throughout history, and the lessons we have hopefully learned from them. Finally, you should be able to critically read primary literature and use it to contribute to the broad conversation about human health in both speech and writing.

We meet on Mondays and Wednesdays. On Mondays, this is a lecture class, covering the texts and the topics listed below. On Wednesdays, this is a fast-paced discussion-based class. Every Wednesday meeting starts with a prescribed question, then progresses to your questions, switching topics at any ≥30-second lull in conversation.

The first week, I would like you to read all five papers. Every week after, you are responsible for reading at least two of the provided texts closely enough to be an expert, and for skimming or lightly reading at least three of the others to whatever extent is necessary for you to be able to respond to arguments and carry on intelligent conversation. In both cases, you are expected to go beyond what we cover in the Monday lecture. Come to class on Wednesday with at least three unique and interesting questions about the text(s) you choose to focus on or their implications to discuss with your colleagues. Highlighted texts are strongly recommended.

This class is a safe space. Please feel welcome to share your questions, thoughts, and opinions, even ones that seem “dumb” or “wrong.” We will work through them with empathy together as a class. To enable this atmosphere, please approach debate and discussion with empathy and enthusiasm, and remember that we are growing together and through each other. One of my favorite professors in undergrad started the semester distinguishing uncomfortable and unsafe. Fruitful discussion and growth can, at times, feel uncomfortable. If at any point this class makes you feel unsafe, let me know.

In lieu of a final exam, you will choose your favorite question proposed by a classmate (not by me and not by you) and write a 500- to 1500-word response to it drawn from the text and from class discussion. I will compile all responses into one anonymized document, and you will choose at least three classmates’ thoughts to respond to in generous tweet-length (≤250 words).

We include both scientific papers and publications from other media. I hope that every week, we will have a balance of experts in all texts in all formats, and that we start every new week more knowledgable and thoughtful than we were the week before.

Introduction to Data Analysis Methods for Biological Inference

Seminar on experimental design, modeling, working with multiple variables, wrangling messy data, genomic sequencing, and popular techniques and tools in computational biology.

This class is an introduction to some of the tools of computational biology. We will look at statistical tests and learn how to disentangle the effects of multiple variables. We will learn how to do genome-wide association studies and principal component analysis. We will learn about how genomic sequencing works, and look at how it can be used for diagnosis or discovery of novel organisms. Finally, we will learn how to use genomic sequencing to trace disease transmission. By the end of this course, you should have the tools you need to analyze your own or publicly available data.

We meet on Tuesdays and Fridays. Tuesdays are lectures on the topics and texts listed. Highlighted texts are strongly recommended. On Fridays, we meet for an extended workshop to apply the week’s tools to publicly available data or to data that you bring with you to class (except in Week 7, when we will generate new sequence data). Before every Friday, you are responsible for writing a short proposal for the week, including what dataset you plan to analyze, what tools you plan to use for what analyses, and any hypotheses you have (≤500 words). At the end of the semester, you will choose whichever workshop was most inserting or successful for you to extend into a short final project, which you can work on alone or in a group. On the last Friday of class we will go around the room and briefly summarize our analyses and findings in an informal setting over snacks.

You don’t have to buy these books from Amazon—you can support local bookshops by buying them from Bookshop.org, or you can buy them used and donate them to or start or build a little lending library in your neighborhood, or you can not buy anything at all. You can also support me by buying merch of my art, by buying me a campground store decaf coffee, or by simply reading and enjoying. Thank you!

Reading is one of my favorite things about being human. I want to share with you some of my favorite books, all of which are very special and cozy to me. I hope if some of them seem interesting to you that you will find them just as special.

(I noticed while writing this, as I’m sure you will notice while reading it, that 71% of my favorite authors are male and 93% of my favorite authors are white. I am working on fixing this and am very open to your book recommendations.)

The Great Gatsby by F. Scott Fitzgerald

“Her porch was bright with the bought luxury of star-shine…”

I fell very deeply in love with The Great Gatsby the first time I read it, which of course was eleventh grade English class. It is my very favorite book. I reread The Great Gatsby almost every year in the early fall—not intentionally, not on any schedule; it just happens. The leaves start getting crunchy and something in me feels that it is time to reread The Great Gatsby.

I love that the story feels more real than reality. I love that the sentence-level writing is beautiful, and that every time I read it I find new beautiful sentences to fall in love with; I love that every word and every punctuation mark is carefully chosen. I love that there is a life (F. Scott Fitzgerald’s and Zelda Fitzgerald’s, specifically) and a lifetime of yearning and struggle written into the story and metaphors—and I love that as I live my own yearnings and struggles, every year and every reread adds my own new beautiful layer to that life (and makes my own life richer).

“So when the blue smoke of brittle leaves was in the air and the wind blew the wet laundry stiff on the line I decided to come back home.”


Ernest Hemingway’s short stories

I first read these stories on exotic warm-place vacations with my family. Whenever I reread them I am back on the soft sands by a warm ocean with gentle waves or with my feet in the warm water at the edge of a pool in unseasonably good weather, reading lovely stories and enjoying the company of the people I love most.

A few years ago I accidentally checked out a (not actually misleadingly named) book of analyses of Hemingway short stories instead of a book of Hemingway short stories. Apparently Hemingway used a strategy of writing a story, then removing the most turning point, leaving the most important things implied rather than explicit. I like the confusing feeling that strategy gives, how I’m forced to think a little, and how his stories linger in my mind for a long time presumably as a result but maybe also because they are beautiful. I also enjoy that every word is deliberate and perfect and that the writing is gorgeous. Rereading these stories does magical things to my brain—no matter how much writer’s block I had starting out I always feel my voice again by the end.

Men Without Women

Winner Take Nothing

“… those were the nights the river ran so much wider and stiller than it should and outside of Fossalta there was a low house painted yellow with willows all around it and a low stable and there was a canal, and he had been there a thousand times and never seen it, but there it was every night as plain as the hill, only it frightened him. That house meant more than anything and every night he had it.”


Neil Gaiman

Neil Gaiman might be my favorite author. I happily read and reread everything he writes. Neverwhere in particular has saved me, again and again, at every reread. Escapism and life’s purpose and dark whimsy and the wonderful gift of getting to feel okay after some sad time of not feeling okay. And always good, engrossing escape with a lovingly crafted and horrifying world to disappear into.

These are my absolute favorites, but everything Neil Gaiman writes is my favorite. Especially special to me, How to Talk to Girls at Parties is another of the few stories that magically and consistently resurrects my own voice when I lose it. Beautiful at the sentence level and beautifully built overall and echoes after you’ve read it.

“Rain in the graveyard, and the world puddled into blurred reflections.

How to Talk to Girls at Parties

Neverwhere

Coraline

The Graveyard Book

“The sky was the perfect untroubled blue of a television screen, tuned to a dead channel.”

“‘You’ll just have to make the best of it down here,’ he said to Richard, ‘in the sewers and the magic and the dark.'”


The Perks of Being a Wallflower by Stephen Chbosky

Another book that can save your life or lift you out of some particular lasting sadness, especially if what you are or aren’t looking for is to feel more okay with yourself. Like what seems like most people my age I first read The Perks of Being a Wallflower in middle school. I reread it this past winter break, back-to-back alongside The Catcher in the Rye (angst!). The Perks of Being a Wallflower is, of course, better, at least to me.


The Glamourist Histories series by Mary Robinette Kowal

Pride and Prejudice—but with magic! And other plots, including a heist novel. This series is excellent escapism with amazing worldbuilding. My partner Cory and I first got to know Mary Robinette Kowal on Writing Excuses before any of these books were published (we’re such hipsters). It’s been very special to get to read these books and to get a bit of a behind-the-scenes view. Everything she writes is consistently amazing and makes me feel like I am ten years old trapped in a book happily with no other priorities.

Shades of Milk and Honey

Glamour in Glass

Without a Summer

Valour and Vanity

Of Noble Family

“The ball crept until the wee hours of the morning, when all the girls spilled out of Branbree Manor and into their waiting carriages, like flowers spilled from a bridal bouquet.


The Lady Astronaut series by Mary Robinette Kowal

Space travel! Women overcoming sexism and racism during a very sexist and racist time! Science getting lots of funding! Magnificent escapism. I read the first two books of The Lady Astronaut series on vacation on the red couch next to the washing machine in my family’s home in Pennsylvania. This series entirely shifted my perspective on climate change.

The Calculating Stars

The Fated Sky

The Relentless Moon

A slight clunk reverberated through the ship as the locking mechanism released from the station. Outside the tiny porthole, fireflies seemed to eddy as the frozen condensation on the spacecraft’s skin came out of the station’s shadow and into the light of the sun. The frost flurried around us, luminescent against the ink of space.


Helen Fielding

“God, it’s hot. Quite like leaning out of the window. Someone is playing a saxophone in effort to pretend we are all in a film set in New York, and can hear voices all around because everyone’s windows are open, and smell cooking from restaurants.”

Stealthily beautiful writing and beautiful escapism and hilarious and such a strong voice. And has made me feel more okay being myself when I really needed to feel more okay being myself, exactly as I am.

His Dark Materials by Philip Pullman

“All around them the wide, clear morning lay limpid in the hollows and pearly blue in the warm air above. As far as the eye could see, the great savanna rolled, brown gold, buff-green, shimmering toward the horizon, and empty.”

I binge-read His Dark Materials (The Golden Compass, The Subtle Knife, The Amber Spyglass) the past few weeks and am now binge-reading the existing two books of the new trilogy. When I was in elementary school I used to read every day, all day, with my mind more in books than in my own life. I don’t often get to experience that feeling and it has been very magical to have it again. Philosophical questions and discussions related to daemons and the corresponding parts of the soul are a lovely bonus.


This Is How You Lose Her by Junot Díaz

I got to take a class with Junot Díaz! I signed up for his longer fiction class in partial rebellion against certain people who thought I should not take any more classes and in part because I really, really wanted to write even though I was an MIT student—because it met in the evenings and because I wanted to be better at writing fiction and because my friends were interested in taking it too.

The class was the most efficiently impactful class I have ever taken. Junot Díaz approaches stories like an engineer, and he understands story like an engineer understands physics or how parts come together or measurements or whatever it is that engineers actually do (I’m pretty sure it’s magic). If I could sit and listen to Junot Díaz dissect stories for three hours a week every week for the rest of my life I would be so happy (and such a good writer, maybe).

At some point after much hyping myself up about it I came to office hours and had nothing particularly useful to say and asked for advice (this was before I started my PhD and learned that it is important to draw out an agenda for every single meeting). He told me to travel and to get my heart broken and to read every day, and he said that reading every day was much more important than writing every day. He said that Lydia five years from then who read every day for five years would be a better writer. I took that advice very seriously and try very hard to make space to read every day, and I try to pay attention to the people and the world around me and to write down what I feel when I feel something. (I think I’m a better writer for it—I’m definitely a better person for it.)

I hadn’t read anything he had written at the time. I bought This Is How You Lose Her at the airport on my flight to join my family for winter break when the semester had ended. There is something very special about reading a new favorite book on the plane, as your one world gets smaller and disappears beneath you and you contemplate your mortality and forgive your life so far and welcome the new world and the new time you’re entering when the plane lands. Like with Hemingway and Fitzgerald I can feel that every word and every punctuation mark is carefully and intentionally placed, and Junot Díaz’s voice (even though I’ve heard his out-loud voice, which I would expect to interfere but it doesn’t) is more real than my own reality. This Is How You Lose Her is another of the few books that consistently brings my own voice back—even if I am stuck and nothing in my head sounds okay and I can’t seem to remember how to write, This Is How You Lose Her makes the words come easily. It is as if the book leaks some of the effort put into it for the reader to absorb. Truly a gift to get to read.


The Position by Meg Wolitzer

The separate but interwoven lives of a family after four children discover an illustrated sex manual (including a brand new position) authored and posed for by their parents. Hilarious and beautiful and heartful and beautiful.


Arch of Triumph by Erich Maria Remarque

Arch of Triumph is one of my mom’s favorite books and now it is once of my favorite books. The voice of the protagonist is incredibly strong and worms into the mind. The first few times I read it, in high school and college, I mainly absorbed the romance plot. When I reread it this year I focused more on the refugees and how the story relates to the world we live in now, and absorbed the romance plot as a metaphor. I like when a story changes as I change and I like this story in particular.


Zoobiquity: The Astonishing Connection Between Human and Animal Health by Barbara Natterson-Horowitz and Kathryn Bowers

Zoobiquity is quite probably my very favorite popular science book. It is hilarious and it is even more insightful and it entirely changed my perspective on our relationship with animals and on our place in history and on my research.

I got to TF Evolutionary Medicine (HEB 1328) with Barbara Natterson-Horowitz in the fall of the second year of my PhD. The class built on Zoobiquity the book. In addition to being an excellent writer and lecturer Barbara Natterson-Horowitz is herself an amazing person—she’s accomplished so much, from her writing to her work in medicine to her teaching and research and beyond, and she has had the most extraordinary adventures—on a more personal level, she believed in me and in my career, both the science and the writing, and being around her and getting to work with her every week was practically intoxicating and of course one of the highlights of my PhD so far.


The World Without Us by Alan Weisman

“They didn’t get that when you cut down the forest, you expose a new forest that rooted in its shade. They never read Thoreau.”

A very well-researched thought experiment previewing the Earth after humans have left. Beautiful and interesting and strange and horrifying and very informative and overall an excellent read.


J.R.R. Tolkien

LOTR is in my opinion by far one of the most beautiful pieces of writing—and of course has extremely engrossing, realer-than-real worldbuilding. The last time I reread it it took me an appallingly long time to get through because I had to stop every paragraph to write down a sentence I found too beautiful to not write down (or more often too beautiful to not post-it-note and type it up later). Tolkien’s world and books were also among Junot Díaz’s favorites to reference in class.

“Here and there golden leaves tossed and floated on the rippling stream. The air was very bright and still, and there was a silence, except for the high distant song of larks.”

“There long the golden leaves have grown upon the branching years…”

The Lord of the Rings

The Hobbit, or There and Back Again

“But if I may be so bold, you’ve come back changed from your travels, and you look now like folk as can deal with troubles out of hand.”

“But when dark things come from the houseless hills, or creep from sunless woods, they fly from us.”


Terry Pratchett

“Sometimes the truth is arrived at by adding all the little lies together and deducting them from the totality of what is known.”

I was first introduced to Discworld by Rob Miller, one of the professors who teaches my favorite computer science class (6.005) and whom I got to TA for during my MEng. Terry Pratchett delivers multiple laughs per page and correspondingly a lot of happiness—a very valuable commodity that, if it can be gotten for free by borrowing a book from a library, should absolutely be gotten for free by borrowing a book from a library.

The Discworld universe is vast. Mort and Going Postal are where I started and I think they were excellent starting points. Going Postal especially is a very excellent book for anyone who codes (but also anyone who does not code!).

Mort

Going Postal

“They listened. They argued. They resorted to mathematics, while words sailed through the night above them.”

Before I started my PhD, I used to collect phrases and sentences I especially liked (snippets) and words I didn’t know well enough to use (new words). Here is that collection:
