Quote of the Day
“Gamma rays are the 800 pound gorillas of photons”
- Phil Plait, the Bad Astronomer in his post The Hulking Sky.
If that isn’t awesome enough for you, he even adds this qualifier:
“Come to think of it, if you could actually turn an 800 pound gorilla into photon, it really would be a gamma ray. When you convert an object into energy (which is what a photon really is), the amount of energy you get out is huge for even a tiny amount of mass. An 800 pound gorilla, converted into energy, would explode with the same yield as about 8000 one-megaton nuclear bombs. By definition, any photon above about 500,000 times the energy of a visible light photon is a gamma ray, so if you could somehow squish all that energy from the suddenly energized simian, it would be a gamma ray. And it would be really ticked off.”
Phil’s blog is truly fantastic, so I urge you to read it if you don’t already.

Phil is awesome. I remember writing to him back in the days before his world-wide fame, supporting his previous website, and he wrote a really nice message back. Not just a bad astronomer, but a really nice guy to boot!
Your posts are great Claire as well. Really enjoy reading about your fascinating career.
