I'm finally getting around to publicly posting my lecture notes from the graduate (quantum) condensed matter physics course I'm teaching. You can find them here, along with my previous lecture notes from freshman-level E&M: u.osu.edu/skinner-352/

This is one of the great (and dangerous) things about getting a PhD: it the last remaining realm of education where there is enormous variance in what and how you learn. It still produces a wide range of thinking styles and competencies among people getting the same degree.

That one time @DavidDeutschOxf spoke to Richard Feynman: “We had a wide-ranging conversation, mostly about quantum theory and computation, but we deviated a bit to talk about physics generally. And I said that physics seems to have slowed down, and he said, “There will be no…



... huh.

This is one of the most aesthetically unpleasant things I have ever seen. Imagine thinking that quantum mechanics is just a jumble partial differential equations and ugly special functions.

Update: I plan to release a second edition of Plastic Fantastic by Kindle and Paperback through Amazon, correcting typos but otherwise not making changes. If you are or know a skilled typesetter available to help me reformat the cover art and manuscript please reach out.

Today the rights to publish Plastic Fantastic: How The Biggest Fraud in Physics Shook The Scientific World, originally published 2009 by Palgrave Macmillan concerning the fraud of Jan Hendrik Schon at Bell Labs, reverted to me the author. 🧵



"almost every physicist uses machine learning in some form" 😭

I'd like to politely disagree with Noah here. First thing - almost every physicist uses machine learning in some form. Not just as a tool among many, but as part of their overall research paradigm, because there's just so much data. BUT, more importantly:

Got a really lovely comment about this lecture from a student feedback survey:

On a whim, I decided to upload one of my favorite lectures: the day I introduce my graduate class to "semiquantitative derivation." I show how they can derive things like the speed of water waves without ever writing a differential equation youtube.com/watch?v=W51GIk…

If anyone knows of an open access platform or printing service that they'd recommend for this kind of re-release let me know.

It's too late: millennials secretly love this outcome and now they're in positions of power.

The government decided to let robocall scammers completely overwhelm our telephone system to the point where it’s basically unusable. Maybe fixing this should be a priority?
