Dear cosmologists, Do you love IA (Intrinsic Alignments)? Do you hate IA? Do you not really know what IA are but they seem important? If any of these apply then I have TWO exciting announcements for you:

Anirban Roy NYU Physics telling us about the mysteries of line emission from galaxies

Simon Batzner (DeepMind), speaking IAIFI two days ago; “Machine learning is IID; science is OOD.” I couldn’t agree more.

Trigger warning: The video to which he’s referring is awful. But we’ve unleashed something terrible. And by “we” I mean the scientists and engineers of the West. Now it’s our job to get these weapons all destroyed. This cannot be the legacy of our work.

Some news: in a few weeks I'll be leaving Flatiron CCA to join Google DeepMind where I'll be working on the JAX core dev team. It's bittersweet to leave astro which (for better or worse) has defined much of my identity for the past 15 years, but I'm excited about new adventures!

Black mathematics postdoc fired for nonviolent political protest: facultyforpalestine.education/april-26-press… #blackinstem #blackinmath

Protests over Israel-Hamas war have torn US universities apart: what’s next? nature.com/articles/d4158…

How is it that I work for an inhumane monstrosity?

Encontré muy interesante este artículo de Hogg y Villar sobre la ontología y la epistemología de machine learning, y su adecuación o conflicto con la práctica científica, arxiv.org/abs/2405.18095

I just had a dumb realization: In the northern hemisphere, your shadow moves clockwise through the day. Probably not a coincidence.

This WaPo article (very long read) is one of the best articles I’ve ever read in the press about engineering. wapo.st/4ghkL5t

There is now an arxiv link describing this work! Check it out: arxiv.org/abs/2409.08090

1 in every 3 people killed by a stranger is killed by a police officer. So you might think the biggest threat to your life is some random shooter or gang. But the one organized group that is most likely to shoot and kill you is the police, and it’s not even close.

Don't forget that, in 2021, the US and Israel were the only countries at the UN to vote against making food a human right.

Super proud of my PhD student Wilson Gregory He won a best paper award at #ml4ps2024 for our work with David W Hogg and Kaze Wong Robust Emulator for Compressible Navier-Stokes using Equivariant Geometric Convolutions ml4physicalsciences.github.io/2024/files/Neu… cis.jhu.edu/~wgregor4/

‘People used to say, about New York: “If you can make it here you can make it anywhere.” Nothing could be further from the truth. The whole point of New York was that it was the city that wanted you to make it.’ theguardian.com/us-news/ng-int…
