Slide 9 refers to “wavelength states” and “modalities”. What are these terms referring to?

Slide 8: Does “measuring the spectrum intensity” mean taking measurements of intensity at different wavelengths which can result in making a graph of intensity as a function of wavelength, as shown in slide 7?

“if a body does not absorb a particular wavelength and instead reflects it, then it’s not going to emit it.”
* all bodies, or just blackbodies?
* what does reflection mean in this context? Does it mean to pass through the body as if the body’s not there? -

“all matter at a temperature greater than absolute zero emit electromagnetic waves, i.e. light. And the reason why it does this, is because these, like, charged particles are being accelerated, and that gives out from the random thermal energy, and that gives off EM waves.”
To flesh this out in the case of a collection of non-ionized hyd…[Read more]

I transcribed the talk using a website, because sometimes I read better than I listen.
=====================Welcome to a series of presentations on the ultraviolet catastrophe and the quantum revolution, plus some statistical mechanics. I decided to pursue this topic because it’s something that is often given, I think, far too short shift in…[Read more]

I’m looking forward to seeing everyone. Mike and I have been dipping our toes into GR as well; would love to hear what you’ve been working on, @scott.

I’ll try to make it! I’ll be on a trip to Alaska but this should be feasible.
I’ve also been working through general relativity so would love to chat about that as a topic. I’m naturally interested in quantum mechanics as well!

Yes, still there. Great!

Yes, Sundays 4:00pm Denver (I *think* that’s 7:00pm in Montevideo. Are you still there?)
For the Portland crew, that’s 3:00pm US West Coast.
Basically, the same as always. -
Eduard Smetanin replied to the topic June 8th: Discuss upcoming meetings in the forum Meetings 3 months, 3 weeks ago
Is it 4pm Denver time?

It’s been a while since we’ve gotten together, and there are some things coming up. So I thought it might be a good idea to have a little informal get together and do some planning for upcoming topics. And generally see what everyone’s status is.
What’s currently on the table:
Stefan will be taking a look at the “Ultraviolet Catastrophe” which…[Read more]

I have a similar experience with AI. I’m curious if this is a fundamental problem with the architecture or it can be solved by enhancing it.
