In class today we used Maxwell's equations to derive the wave equation for the E & B fields in empty space.
When you ask them to calculate 1/sqrt(mu_0 epsilon_0) and they realize that number is the speed of light is a pretty great moment!

Physics is the realization that math represents reality. Physics is fundamentally, *essentially* theoretical.
Where experiment comes in is that nature is the arbiter of our theories.

Tangentially, consider the following: if you like your insurance and want to keep it, there's a very good chance that's because you haven't had to use it and thus don't realize what garbage it is...

More than once I've heard "I have a comment" followed by "I have a comment on the comment" followed by "I have a comment on the comment on the comment".
Sometimes that leads to "DOES ANYONE HAVE A QUESTION FOR THE SPEAKER?" but not often enough.

I honestly think it's a good amount of both. And as an addendum to that, I think the nearly impossible job market is really a key part of the disillusionment with academia (even though there are many other things about it that can also cause disillusionment, especially now).

Noether BTW was one of the greatest mathematical physicists in history. Her insights underpin much of modern day fundamental physics. The unifying idea behind linear & angular momentum conservation? Noether’s theorem. Scandal that she’s not more famous

You don't learn anything just by measuring shit. You learn by measuring shit and then comparing that new information to what you knew before. Sometimes it's direct comparison to models, other times it's comparing to (and building on) previous experimental results.

A humble request to the physics and astronomy communities: just abolish the Rumor Mill entirely. It benefits no one and harms many.
And as a friendly request, for both your mental health and the health of our server, please go easy on refreshing the Rumor Mill pages. That didn't cause the problems this morning, but it has given us issues in the past.

All experimental results, even completely by themselves, rest on previous theoretical knowledge. Sometimes that knowledge is so well-established that it's all too easy to overlook, but it's still there.

My favorite physicist of all time. I always discuss her and this result when I give talks about searches for P- and CP-violation in heavy ion collisions. She definitely deserved the Nobel Prize, and it’s shameful that she didn’t get it.
Chien-Shiung Wu, who gave an experimental proof of parity violation in weak nuclear decay, was born
#OTD
in 1912. Her 1956 experiment involving the decay of Cobalt-60 confirmed that the weak interaction does not respect what many had assumed was a fundamental symmetry of nature.

One of the greatest experimental physicists of all time, and a personal hero.
Some truly exciting news: my grandmother, Dr. Chien-Shiung Wu, is going to be on a Forever stamp from the U.S. Postal Service. She was a nuclear physicist who helped disprove a fundamental law of nature and changed a field dominated by men. We’re so grateful for the honor.

Awesome thread with lots of great stuff about blackhole thermodynamics, which I hope to touch on in my thermal physics class this semester!
Stephen Hawking was born

in 1942. He developed theorems with Penrose that determine when general relativity produces singularities, established classical laws of black hole mechanics, and hypothesized that quantum effects make black holes radiate.

Nonsense like this:
Controversial opinion: Physics is overrated. Statistics gave us linear regression which allows us to make simple extrapolations from almost any kind of numerical data. This ability has contributed massively to human progress. Much more useful that some silly physics equation.

I'm thinking about pure math and pure physics which, in contrast to their applied variants, do not have any direct or obvious technological applications. We do them because we love them, not because they have any practical value. They are, perhaps paradoxically, very human.
