Relativity 9 - mass and energy

The most recent in a series by one of my favorite science posters on YT. This is my first sift, let me know what you all think.

As much as i love science, i really can't appreciate this style. I watched a few bits and found that the language he used was over complicated for simple ideas, he talked very quickly over even mathematical content and in a fairly monotone style which only made it more difficult to follow, and the visuals weren't very good either because they were utterly filled with text - the whole point of visuals is to simplify.

I think anyone would get more out of even a half decent text book.

I was thinking the same as you two, especially about the level, but then again, anybody who thinks they're going to understand relativity without a very strong grasp on mathematics is, well, like me, totally deluding themselves that they can ever really understand it. But still I plod on, starting with a couple hundred hours of Khan Academy videos. Hopefully there'll be some quantum physics ones up there by the time I'm through the Linear Algebra, Calculus and Physics playlists.>> ^dannym3141:

Yeah, this is perhaps too advanced for somebody without a very solid foundation of maths. Still nice though.

Yeah, I think you're right. Mathmatics is the language of Science. People are turned off by seeing equations with wierd triangles in them, and letters with subscript 1s and 0s when its really just shorthand for things they already understand. I think it would be possible to describe almost all the contents of this video in plain english with simple maths, but it wouldn't be nearly as concise or precise.

Basically. I watched this video because my 16yr old sister has been doing relativity in school and I thought she might find it useful. After watching for about a minute I realised she wouldn't get any of it.

I'm doing physics at a master's level right now, i understood the video because i already understood the physics, however the maths explanations were too fast and confusing for me to even relate to the maths that i already know must appear! It's only when i saw it on a huge screen of formulae that i strung it all together.

As for your sister; that's why i mentioned the text book. This is degree level stuff, and anyone understanding it either already knows it or would get far more from a textbook anyway. Tipler 6th edition for example explains this in less time (!) and better.

It's just a bad presentation, but i knew it would get 10 votes and i'm happy to see you lose your p. (to bloodscourge that is, ofc)
