A review on protein language models
Protein “language” is a lot like human language. Given the similarities, researchers have been building and training language models on protein sequence data, replicating the success seen in other domains, with profound implications. In this post, I will explore how transformer models have been applied to protein data…

If I could dissect a sauropod
Luke Horton asked in a comment on a recent post: Given the chance to examine a titanosaur cadaver with your hypothetical army of anatomists, what would you look for first? *FACEPALM* How we’v…

My Hour of Memoryless Lucidity
Yesterday, I had a coronectomy: the top halves of my bottom wisdom teeth were surgically removed. It was my first time being sedated, and I didn’t know what to expect. While I was unconscious…

Quark Stars
Wow — evidence that very massive neutron stars may have cores made of deconfined quark matter! The idea of a ‘quark star’ is not new, but I didn’t know it was a serio…

Ten Noteworthy AI Research Papers of 2023
This year has felt distinctly different. I've been working in, on, and with machine learning and AI for over a decade, yet I can't recall a time when these fields were as popular and rapidly evolving as they have been this year. To conclude an eventful 2023 in machine learning and AI research, I'm excited to share 10…

Legendre transform, better explained (2017)
The way that most physicists teach and talk about partial differential equations is horrible, and has surprisingly big costs for the typical understanding of the foundations of the field even among professionals. The chief victims are students of thermodynamics and analytical mechanics, and I've me

Hacking physics from the back of a napkin (2020)
February 24, 2020. The computational power of a humble napkin is awesome. I discuss three napkin algorithms — dimensional analysis, Fermi estimates, and random walks — and use them to figure out why rain falls, the length of the E. coli genome, and the mass of a proton, among other things. These examples suggest a…
