My personal blog, focusing on issues of chemistry and metascience, unified by trying to answer the question "how can we make science better"?

An (in)famous code challenge in computer graphics is to write a complete ray tracer small enough to fit onto a business card. I've really enjoyed reading through some of the submissions over the years (e.g. 1, 2, 3, 4), and I've wondered what a chemistry-specific equivalent might be. As a first step in this space—and as a learning exercise for myself as I try to learn C++—I decided to try and write a tiny Lennard–Jones simulation.

Spoilers below for Ursula Le Guin’s short story “The Ones Who Walk Away From Omelas.” If you haven’t read it, it’s short—go and do so now! TW: child abuse, suicide. In her short story “The Ones Who Walk Away From Omelas,” Ursula Le Guin describes an idyllic town (Omelas) built entirely on the misery of a single, innocent child.

The failure of conventional calculations to handle entropy is well-documented. Entropy, which fundamentally depends on the number of microstates accesible to a system, is challenging to describe in terms of a single set of XYZ coordinates (i.e. a single microstate), and naïve approaches to computation simply disregard this important consideration.

In the course of preparing a literature meeting on post-Hartree–Fock computational methods last year, I found myself wishing that there was a quick and simple way to illustrate the relative error of different approximations on some familiar model reactions, like a "report card" for different levels of theory.

Who is Peter Thiel? Tyler Cowen calls him one of the most important public intellectuals of our era. Bloomberg called him responsible for the ideology of Silicon Valley “more than any other living Silicon Valley investor or entrepreneur.” Depending on who you ask, he’s either a shadowy plutocratic genius or a visionary forward-thinking genius: but everyone seems to at least agree that he’s a genius.

This is the second in what will hopefully become a series of blog posts (previously) focusing on the fascinating work of Dan Singleton (professor at Texas A&M). My goal is to provide concise and accessible summaries of his work and highlight conclusions relevant to the mechanistic or computational chemist. Today I want to discuss one of my favorite papers, a detailed study of the nitration of toluene by Singleton lab at Texas

Over the past few weeks, I’ve been transfixed, and saddened, by Eric Gilliam’s three-part series about the history of MIT (my alma mater ). I’ll post a few quotations and responses below, but if you’re interested you should just go read the original essays (1, 2, 3). Why MIT Was Created This quote highlights how MIT was intended to be a counter-cultural university, founded on a distinctly different model than other institutions (like
