Try this experiment: put to mirrors parallel to each other, look at one of them close to a right angle, count how many repetitions of the same image you see and now think how many times light bounced before reaching your eye. Light bounces losing intensity depending on surface color or shape.

Oct 24, 2011 - I wish this guy helped to explain the 10 dimensions video which is floating around on youtube.

Oct 29, 2011 - wonderous, how IQ is not so much involved in genius. He had an IQ of "only" 125. This inspires me to study physics :)

Nov 9, 2011 - Every time I feel a bit down, all I have to do is get a good dose of Feynman. Cheer you right up...

Dec 3, 2011 - @nsrussell267 the "10 dimensions" stuff was invented by string theorists. An untestable, unprovable made-up mumbo jumbo that they themselves cannot understand. Richard Feynman disliked string theory. If you watch more stuff about Feynman you will eventually understand that this guy believes only in the stuff that is tested and proven and everything else is just "well it could be true or could be not true, I don't know". String theory is like a religion at this moment.

Dec 8, 2011 - @Indrius Incredible math... but unfortunately the theory is incredible too... As in NOT credible ... in-credible.

Jan 13, 2012 - So if light and heat and radio waves are all the same thing but at different wave lengths, what is it that is oscillating? Light particles? That would mean that a radio transmitter transmits light particles. That hurts my brain. Someone help?

Ixezed Says:

Jan 14, 2012 - @Paggee Electromagnetic waves are electric and magnetic field oscillating, one driving the other. There's no medium of propagation, electromagnetic waves can propagate in total vacuum. You could say it's pure energy propagating (quanta, photons) that exhibits wave-like properties.

Jan 23, 2012 - His fraternity challenges sound very intellectual. I thought that fraternities made guys drink 20 beers and then swim across the fountain with lit candle in their ass or something like that, not solve physics problems. Maybe it's changed since the 40s.

Graath666 Says:

Jan 28, 2012 - whats his story?

Penthaligon Says:

Feb 2, 2012 - But, this is awesome! He is making even me feel brilliant.

Feb 3, 2012 - @Graath666 Caltech genius of paticle interaction.

Feb 10, 2012 - Light is an electromagnetic wave. However, it is also a particle, a photon. Physicist can explain how it is both but it is. Is sound also a wave and a soundton?
