Hi, I'm Drew Pendergrass. My GMO-free, boneless, gluten-free website is lovingly built from whatever I decide to post online. It hosts a variety of projects, resources, and ephemera made over the years, including experimental music, my writing, a video game, a fake startup that sells logs on wheels, a stupid Chrome extension, and esoteric sorting algorithms, as well as my research papers and conference presentations in atmospheric science and related fields.
Currently, I am a doctoral student in Environmental Engineering at Harvard University, studying under Daniel Jacob, and I freelance on the side for publications including Harper's and The Guardian (send me stories at drew@drewpendergrass.com). More importantly, I have never traveled to an exoplanet, I have no trouble distinguishing my right from my left, and I am not a closed, non-orientable, boundary-free manifold.
The latest science!
Pendergrass, D. C., D. J. Jacob, S. Zhai, J. Kim, J-H. Koo, S. Lee, M. Bae, and S. Kim. (2021). Continuous mapping of fine particulate matter (PM2.5) air quality in East Asia at daily 6x6 km2 resolution by application of a random forest algorithm to 2011-2019 GOCI geostationary satellite data. Submitted to Atmospheric Chemistry and Physics. PDF. Associated dataset available from Dataverse.
Figure: Daily PM2.5 concentrations during a pollution event in the North China Plain, around Beijing (December 16-21, 2016). Predictions from the random forest algorithm (background, on 6x6 km2 grid scale) are compared to observations made on the ground (circles). We see that the model is able to reproduce even this extreme level of pollution.

A Brief Q&A
Q. How can I contact you?
A. You can follow/DM me on Twitter, but I'm trying to stop using it so much, so it's best to email me at drew [at] drewpendergrass [dot] com (or the academic address in my CV). However, if your email is unpleasant, you should direct it to grievances@drewpendergrass.com, an inbox I definitely read.
Q. Why does this page keep changing?
A. This page is randomly generated by the server on each load. Most of the page's contents are not displayed on one particular load, so for the full experience reload a bunch of times.
Q. Why don't you just host this crap on Github like a normal person?
A. Github only allows static websites. I wanted my website to be different for every visitor. DrewPendergrass.com, like life itself, must always be in flux. You could say I'm an artist.
Q. Who are you?
A. Well, to start off, you cannot prove I have sympathies for the former state of Burgundy, I have never commanded an army composed of more than 100,000 soldiers, I hold no world records, I take my eggs over easy, and I did not orchestrate the Camp David Accords. If you for some strange reason would like to know something substantial about me, you can check out my projects page or my CV.

Some true statements
A Moving, and Random, Quotation
Only art penetrates the seeming realities of this world. There is another reality, the genuine one, which we lose sight of. This other reality is always sending us hints, which without art, we can't receive.

Three Cryptic Messages Regarding Matters of Supreme Importance
- Please beware your morals before they review your gods.
- All ideas have been purged. Please corrupt the liberties.
- Your regulations will be surrendered.
One randomly-generated sorting algorithm, please!
Do you have an unsorted list of N natural numbers? Do you just hate it when programs are guaranteed to terminate? Do you get angry when algorithms do better than factorial time? Then you're in luck! The following algorithm has been generated just for you:
- Feed your list into a black hole, permanently destroying the information. The list is as good as sorted now! If people shake their heads and insist you actually sort the list, just generate a new one and proceed to the next step.
- Uh oh! You've triggered a penalty step. Before you proceed, you must perform a task. Andrew Wiles's proof of Fermat's Last Theorem is 109 pages long. Assuming each page contains roughly 2000 characters, the text can be encoded in order 1,000,000 bits. Generate this number of bits and check to see if they prove Fermat's Last Theorem. If they do not, repeat this step. If they do, proceed! You've paid the penalty. (This step was defined in collaboration with Mirac Suzgun).
- You turn to mathematical ecology for inspiration. For each number in your list, generate a population of rabbits proportional to the number and a population of wolves inversely proportional to the number. Wait for each system to equilibrate. Read off the equilibrium population of rabbits in order of population size, printing the number corresponding to each. (My lab partner Jackson Wagner points out that this is not a true sorting algorithm, since you still have to sort the population sizes. To Jackson, I reply that this is the least of our worries.)
Congratulations! Your list is now sorted. You can find a permalink to this particular algorithm here.
