About mattlangston
https://x.com/mattlangston
https://mattlangston.com
Matt Langston holds a PhD in physics. As an experimental physicist at the Stanford Linear Accelerator Center (SLAC), he designed and built particle detectors to probe the foundations of physics at the quantum level.
He is also a Research Software Engineer with over 20 years of experience bridging research teams and software engineering teams - currently at Apple for over 10 years, and previously at SLAC, Microsoft Research, and several acquired startups.
Matt's current research applies the experimental physicist's toolkit to Large Language Models: measuring their equations of motion in search of an LLM Standard Model - a unified framework describing how and why LLMs work.

Software engineering is software engineering. An ace software engineer is not an ace because of tooling. It's not the plane, it's the pilot, or something like that.

Boris Cherny has said that Claude Code is simply a client of the public Claude API, so this may be a good thing for Anthropic to demonstrate Claude API best practices. Maybe CC "le…

I had the same SETI inspiration yesterday of "autoresearch swarms". Andrej and I had no coordination - we just both had the same idea at the same time. Experiments already running.…

The future is bright for software engineers. The big takeaway isn't reverse engineering the ANE per se, but what Manjeet could do with his software engineering skills when accelera…

The frontier-of-knowledge point is the right question. My own research is a case in point - I apply experimental physics methods to LLMs, measuring their equations of motion in sea…

Good question. It's mostly the third — but let me unpack that. The Standard Model predicts a specific value for the weak mixing angle, which determines the electron's vector coupli…

Comment #46965679
Fair - that sounds hyperbolic. But my point is specific: if the weak mixing angle is shifted from the Standard Model value, one of the standard explanations is a heavier cousin of …

Experimental particle physicist here. It's just hard. I measured the electron's vector coupling to the Z boson at SLAC in the late 1990s, and the answer from that measurement is: w…

It does well with screenshot-calculus for me. For example, I pasted a screenshot of the Layer Norm equation into Claude Code 2 and asked: "Differentiate y(x) w.r.t x, gamma and bet…

fwiw I live in [macOS emacs]( https://emacsformacosx.com/ ) all day long for systems engineering (C/C++) and have 201 open buffers, an uptime of 57 days and ~540 MB memory usage.

I have both a Claude subscription plan and console credits as my backup, which I thought was a reasonable solution.
