Thread: Review: Why Does E = mc2?

Started 1 month, 1 week ago by ottermon
THE breezy title of this book conceals the authors' ambition. To get at the origins of E = mc 2 , the poster-child for Einstein's special theory of relativity , they must delve into deep principles of science and wield a good deal of mathematics. They do it well, aside from a few too many digressions and an over-optimistic attitude that "you will have a go with the maths even if you...

Yeah, Otter(B) - i enjoy the Colbert Report, too

sisyphus replied 1 month, 1 week ago
Well, an interesting question, Otter(B). If one accepts Maxwell's lovely melding of 'electricity' and 'magnetism' into 'electro-magnetism'...there is an interesting parallel with Einstein's work. What word can we coin for this?? Hmmm 'kineto-[thinking 'gravitism', but that hasn't quite been elucidated, yet]-materialism' (as close as i can come, as 'kineto-massism' just doesn't seem to ...

Why Does E = mc2? Because Einstein said so

sisyphus replied 4 weeks ago
well, he tried 'E = m a^2" and "E = m b**2", first..but he thought that would be more memorable...

Because Einstein said so Another swallower of codswallop?

LOL. If ya ask me, I would say E=m. Mass is simply condensed energy. Can't fathom what the speed of light has to do with it.

simplykatie replied 3 weeks, 5 days ago
And the thing is, how would you know? How could one possibly measure the energy that makes up a single atom? We can observe that it's an amount. I'm not aware of any measuring device for this. Anyone know?

Well, when one considers the 'composition' of atoms, each element with its chararcteristic number of protons and electrons (with a varying, but limited range of the number of neutrons - the varying number of neutrons is waht makes them 'isotopes'), the atomic mass is defined as the number of protons plus the number of neutrons. The neutrons have slightly more mass than the protons, while the ...

Well, Katie(F)(B), i do enjoy the wider range of your thoughts and questions, musings. While there are 'scientific' views/interpretations of things, and 'mystical' interpretations, one should try to 'separate' the two.  (i consider myself an Alchemist, in the 'ancient' tradition, but also, quite the modern scientist). First, it is thought that the Sun radiates its light in all driections, as a...

Superlight! I like that. That fits with what I understand sort of. Need to think about it more.   In closing, a word about the significance of 'speed of light squared' in E = mc**2...      The acceleration of a falling body in Earth gravity is (I think!) Acceleration equals 32 feet per second per second, i.e. A = 32 (ft/sec)**2.  In other words, a falling object goes faster the...

Written out it reads: "The amount of energy contained in an atom of matter is equal to the mass of that atom times the speed of light multiplied by itself." The speed of light is not used as a measure of speed here but as a measure of amount only.

 Katie: So how much energy does an atom contain when not in motion..... http://web.jjay.cuny.edu/~acarpi/NSC/3-atoms.htm the particals in an atom are always in motion.....  or are you talking-asking about atomic weights???  if so then that varries by whatever element you are examining

Katie #50 " Golly Gosh. There has to be a simple way to explain all of this. And still nothing mentions what the speed of light has to do with it." "I have much more thinking to do on the subject. I tend to think beyond the norm when something doesn't make sense. " . As long as we are into speculative adventuring here, I'd like to throw yet another idea into the mix... the concept of SuperLight....
