Applications of Classical Physics
- octed 1y agoFor those who would like a print version, this manuscript eventually got published as Modern Classical Physics https://press.princeton.edu/books/hardcover/9780691159027/modern-classical-physics https://press.princeton.edu/books/hardcover/9780691159027/mo...
- mhh__ 1y agoI was weighing up (...) buying a copy of this the other day, in a physical bookshop. The thing was so big I couldn't actually buy it.
- kurthr 1y agoThere has always been commentary that the size (over 1300 pages) of the General Rel book Gravitation by Meisner Thorne and Wheeler was done for demonstration purposes. Apparently, modern versions are only 2.5" thick which leads me to believe they must be on incredibly thin paper. I remember it being about 4-5". https://www.amazon.com/Gravitation-Charles-W-Misner/dp/0691177791 https://www.amazon.com/Gravitation-Charles-W-Misner/dp/06911... Maybe tome size a Kip thing?
- mhh__ 1y agoThe thing with MTW is that it's so big that it's quite hard to really mull over it (for me at least). it's a book that I can imagine reading a lot in a very quiet world (i.e. basically a dorm or library before phones or computers) but it's very hard to actually get my teeth into it without that.
- kurthr 1y agoYeah, unless you're taking a class like ph236 covering the material it's just absurd. I hadn't realized it, but it looks like this new book is for ph136 the junior level (1st year grad) general rel prep class. https://www.its.caltech.edu/~esp/ph136b/text.html https://www.its.caltech.edu/~esp/ph136b/text.html
- mhh__ 1y ago"General relativity for the gifted amateur" just came out by the way. I suspect an instant classic. I am very rusty so shall be going through it.
- cshimmin 1y agoInteresting that they changed the author order to put Kip Thorne first... marketing?

- macintux 1y agoWell, that sounds legit. > Many so-called mainstream physicists who believe in quantum theory dismiss your theory as pseudoscience. What is Mills Grand Unified Theory of Classical Physics (GUTCP) underlying the SunCell® that harnesses the new, pollution-free primary power source based on forming Hydrinos®?
- omneity 1y agoFor me it’s the double question marks that showed me how serious they are: > Q: What is the founding principle of Mills GUT-CP??

- dave333 1y agoOn page 15 of the Introduction in https://brilliantlightpower.com/GUT/GUT_Volume_1/ https://brilliantlightpower.com/GUT/GUT_Volume_1/ there's a list of 19 (counted em) shortcomings of Quantum Theory based on Schrodinger math.
- xqcgrek2 1y agoFor an idea of how far the average US physics education has been dumbed-down in the past three decades, I doubt a 3rd year US-educated physics graduate student could pass a test on any of the chapters.
- slyfox125 1y agoWe are victims of our success.
- TimorousBestie 1y agoI don’t think this is very accurate. Classical fluid dynamics is a dying art, yes, but classical mechanics and electromagnetics are still a huge part of the curriculum.
- kurthr 1y agoWith or without a LLM "partner"?
- momoschili 1y agoThe vast majority of US grad students already pass tests on chapters 1-9 (the ones that are taught) before they even begin their "true" graduate career (aka their "masters"). Most graduate E&M (Jackson) and Thermo/Stat (Landau) mech classes cover their individual topics to an even greater level of detail than these materials. As for the uncovered subjects, it turns out quantum mechanics occupies a large space of the "new physics" that graduate students are trained to do. There are definitely an incredible amount of utility and knowledge to be gained from the classical field theories, and obviously many outstanding and new problems that I think need more attention as well. At the same time let's not understate the utility of quantum mechanics that most grad students are specializing in. You are speaking out of turn.

- srean 1y agoI will probably date myself with this comment, but in my highschool days there used to be this TV series called the Mechanical Universe produced by Caltech. It was so fantastically good, perhaps peak pedagogy for its time. https://youtube.com/playlist?list=PL8_xPU5epJddRABXqJ5h5G0dk-XGtA5cZ&si=ejT8_7Dma0vWOodH https://youtube.com/playlist?list=PL8_xPU5epJddRABXqJ5h5G0dk...
- hyperjeff 1y agoI watched that series multiple times when i was in high school and early college. Really inspiring and the visualizations still live in my head. Unusually good production for an educational show. Set a new standard.
- zokier 1y agoInteresting that relativity is included here; to me it's one of the main things separating modern physics from classical.
- matheist 1y agoI think in modern physics "classical" often means "not quantum", rather than "pre-modern".
- dawnofdusk 1y agoTypically non-relativistic and non-quantum is called "Newtonian". Classical is just for anything which is not quantized, and so far no one knows how to quantize general relativity.
- dreamcompiler 1y agoClassical means "not quantum." It doesn't mean "not relativity." Relativity is a classical discipline.
- momoschili 1y agoI just looked through the diffraction chapter and some chapters I'm much less familiar with. This is an incredible ~graduate level text for these subjects. I've been looking for something like this for a while! Thanks!
- reader9274 1y agoSkimmed through chapter 1. That sounds like the way I was taught this subject in high school, nothing revolutionary. Not sure why they're talking so much about its brilliance
- dawnofdusk 1y agoYou learned about stress tensors and PDEs in high school?
