ChatGPT: Sorry Dave, I can't do that.
Me: Fine, I'll do it myself...
I create videos about materials science.

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.

This is an example of how the “don’t comply in advance” idea falls apart.
I received a heartbreaking email today: A paper in a special issue I’m editing is being retracted because one of its authors is afraid of losing their job and their legal status in the U.S. if they publish a scientific study on evolution. Yes, on evolution, nature's engine of diversity.

Better download any NIST spectra you might need. Who knows if they will stay online after the atomic spectroscopy group gets shut down.

There is a movement afoot to get the SI unit for momentum (kg m/s) named after her:
It is time to honor Emmy Noether with a momentum unit
I have been teaching physics, on and off, for 30 years now, and every time I get to momentum and start writing “kg m/s” for the unit, my students ask if there i

The tech industry leadership seems to have concluded that AI will soon reach "PhD level". I wonder how much of them are thinking that they will soon be able to keep getting their cool shit without having the nerdy (science) baggage that come with it.
