The University of Nottingham is pretty awesome.

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!

hey, lets talk about x-rays!
skin is boring; I want to see skeletons!

University of Nottingham eh?

University of Nottingham has lots of cool video projects going on... Sixty Symbols, My Favorite Scientist, this series...

MRI Industry:
Reflecting the fundamental importance and applicability of MRI in the medical field, Paul Lauterbur of the University of Illinois at Urbana-Champaign and Sir Peter Mansfield of the University of Nottingham were awarded the 2003 Nobel Prize in Physiology or Medicine for their "discoveries concerning magnetic resonance imaging".

Microwave Industry & Cellular Communication Industry:
Maxwell, Hertz, and nearly half of all microwave parts that I can think of were first introduced at NIST... These two I am not going post supporting evidence for.


Nuclear Energy Industry:
Err... Quantum Mechanics- Hello?

Computer Industry(By way of the transistor, substrates, etc.)
http://en.wikipedia.org/wiki/Transistor
http://en.wikipedia.org/wiki/Julius_Edgar_Lilienfeld
He created it at the University of Leipzig. Funded by the German government.

Genetic Engineering Industry

Your claim is that without government incentives, these industries would not exist, or would have progressed slower? Can you prove that?

How can I prove something wouldn't exist if people hadn't invented it? The best I can say is it would not have been invented when it was. And scientist wouldn't research whatever they wanted without funding, which companies wouldn't and don't pay for because it is to financially risky. How do I know this? I am a scientist.

Another good example is your IPod and the colossal magnetoresistor in it's hard drive.
