    Mathematical definition of a rigid body

    I guess most people wouldn't see them in Math forums.

    Graduate What Exactly Is The Physical Content Of Maxwell's Equations?

    I have a problem with coming up with something at hand, I learned most of these things from different papers and from people I worked with. And from lecture notes, but these are in polish. But I do have a lot of materials from that period (it's been over 10 years ago) on my backup disc, I'll...

    High School Photoelectric and summation of photons energy

    As far as I know, proper quantum mechanical explanation does not require EM field to be quantum. It requires electrons to be quantum, EM field can be treated classicaly. I know everyone is hung up on Einsteins explanation from 1905, but it was (by his own words) heuristic and things moved on...

    Graduate What Exactly Is The Physical Content Of Maxwell's Equations?

    May or may not. Differential geometry is my specialisation within mathematical physics, and when I tried to study geometric algebra it only gave me headache and different forms of depression. Differential geometry, done properly (not like most physicstis do) is (for me) the way to go. Long live...

    Undergrad Looking closely at the descent into a black hole

    I still see no math, only bunch of words.

    High School Is there anything in the Universe that is not fundamentally made up of matter?

    Oh please, stop this nonsense. Even in ordinary language there are tons of words that have multiple meanings, depending on the context. It may be a problem for those who are learning the language, but not for those who are fluent. The same goes with physics, maths, every science, and other...

    High School Is there anything in the Universe that is not fundamentally made up of matter?

    @Amazed, could please stop telling me, and other physicists, how to do, understand and think about physics? You don't go to surgeons and tell them how to perform surgeries, do you? So I don't see why you do that with physics. Don't waste your time, take textbooks and LEARN PHYSICS. At some point...

    Can Dogs Talk Using Buttons?

    Oh I hate most dog owners. Especially those whose dogs run around without leash and approach my dog. My dog also always walks without leash, but he does not run to other dogs, he sticks with me. And my favourite "He/she won't do anything!"... Well, "But I will." :cool: Anthony has been attacked...

    Undergrad The missing 3D magnetism theory

    I don't think paragraphs can help: I don't know what you are talking about. The same goes with rest of your post.

    Music What Happened to Talent?

    Well, some people genuinly like artists in slutty clothes. I do. I also like electronic music and processed vocals. And to make something good out of it requires talent. A lot. And I rarely like someone who only sings power ballads with 5 octaves and stands still on stage. If one does like that...

    Convert Circular motion into figure-8 shaped loop

    Well, I'm interested in that too, so thanks for the digression :wink:
