So I have a list of video channels I turn to for my youtube science and information tidbits. I figured I would share mine, and we can make a list

I also subscribe to a number of thorium energy channels for their video content, which is a very narrow focus, but Ill throw them in anyway.

what yall got?! I am interested in more chemistry and geology if you got it!

Facts and figures about this video at http://periodicvideos.blogspot.com/2011/04/egg-crash-test-stats.html

X-Rays are extremely high energy Photons which have enough energy to pass through dense material(as with Gamma rays), this allows most X-Rays to pass through the body, with extra dense part(bones etc) to absorb them.

I'm not sure how this relates in terms of the Energy Gap though; you should e-mail such questions to sixtysymbols@hotmail.co.uk and I'm sure Brady will pass them on to the Professors.

A ton of other videos can be found at www.sixtysymbols.com too, and chemistry based videos are also found at http://www.periodicvideos.com/

All answers are given by staff at The University of Nottingham (UK), I'm a student there and have been(and still currently being) taught by most of the people in these Physics videos and it's great seeing people so amazed by some of the stuff they say in their videos, their lectures are always as good too!
