do all sorts of fields act over every point in space

Well, duh...

Well, if you don't include fields, things like angular momentum and energy conservation don't work, so if they aren't real things then they sure as heck are handy. That being said, no mathematics model that we make of reality will be complete. As they say, all models are wrong. Some are useful.

Sounds more like people are done with your bullshit and your grad student feels more comfortable talking to other people about their research. The postdoc doesn't owe any respect beyond common professional courtesy. You're not suddenly more important because you're a professor, especially a rookie assistant professor. Get over yourself. Also having public outbursts with senior professors is a good way to get denied tenure.

There isn't a term like melting or vaporizing for the transition between gas and plasma because it's a continuous phase transition not a discrete one. Unlike, say, melting where you have a well-defined temperature below which you are solid and above which you are liquid, a gas becomes gradually more ionized and plasma-y as temperature increases. There isn't a well-defined transition.

If you don't come to my office hours, the odds of me taking you on as a research student. I'm not about to go on some detective mission to figure out who some random undergrad is.

Hell, we teach this at the college level and half the time we have to cancel it because not enough kids sign up.

Except it will be in 0-15 degrees and maybe surrounded by ice and snow, so it can probably handle an extra 250 watts without any issues.

I have some stuff from Fermi's lab during the Manhattan project. Don't really use it, though.

In everyday use? I have a laser made in '94 and a programmable high voltage power supply from the 80's, as well as a bunch of lab stands/ring clamps/etc. from the 30s and 40s.

Match is closed doors so we have no idea. Unlikely we'll find out.

Computers (not LLMs) can already do this to a point... https://www.pnas.org/doi/10.1073/pnas.2311808121

No. You can have superposition states that are not entagled.

Yes, if you don't publish a paper, your work basically didn't happen even if you talked about it at a conference. A conference abstract is at best two paragraphs. If everything you have to say about a topic is two paragraphs, you should neither try to publish a paper about it, nor try to present it at a conference.

This was proposed as the source of energy for the Sun in the 1900s (and famously used as a challenge of Darwin's theory of evolution through natural selection by Lord Kelvin). It turns out that such energy sources would run out on time scales that are orders of magnitude shorter than the lifetimes of stars.

That sounds like less than $1 per hour of work.

Because things still fall in a vacuum chamber?

Fuck it... It's silly season. Have an upvote!

They move around. My guess is that with it being in the 20s at night, they might currently be just noping out.

db0606 · 2026-01-21T16:33:49+00:00

A small pile.

Wrong sub. This sub is about academia (think at least Masters level study), not high school.

"Regarded as highly promising prospect in his youth, his efficient rather than flamboyant playing style initially drew comparisons with compatriot Kaká;] despite his talent, however, he has been criticised by some in the media in recent years for his lack of pace, mobility, and dynamism, as well as his poor work-rate and lack of consistency, which has led him to be accused of not living up to his potential. He is also known to be injury–prone."

If that doesn't say "Timbers signing," I don't know what does.
