I work out of our office on One Market Street in San Francisco. My standup-desk is right across from our Gallery at One Market. One of our newer exhibits is called Powers of Design. It was first featured at the Technology Entertainment & Design (TED) conference last year. Powers of Design depicts the size of everything from the inconceivably small to the mind-blowingly large. I thought I'd cover the exhibit elements, one at a time, over the next few months. I started small and am working my way up. On Monday we talked about the size of the nothing space that exists between the nucleus of an atom and its electrons. Now we're jumping up in magnitude to a gamma ray. Whoo hoo!

Gamma Rays
Less than 10 Picometers
Long beloved by writers of science fiction and comic books, gamma rays have been responsible for everything from mutant lobsters to super powers. But gamma rays are actually quite prevalent in our lives. As electromagnetic radiation of high frequency and short wavelength, they can be produced in a variety of ways, including supernova explosions, the destruction of atoms, or the decay of radioactive material in space.
Gamma rays have wavelengths less than 10 picometers, or less than the diameter of an atom. Gamma radiation has several everyday uses, including sterilizing medical equipment, keeping food fresh, and gamma knife surgery, an effective treatment for brain tumors and functional disorders.
Gamma rays are responsible for turning Dr. Bruce Banner into the Incredible Hulk. They are the highest energy form of light. The rainbow of visible light that we are most familiar with is just part of a far broader spectrum of light, the electromagnetic spectrum. Past the red end of the rainbow, where wavelengths get longer, are infrared rays, microwaves and radio waves, while beyond violet lie the shorter wavelengths of ultraviolet rays, X-rays and, finally, gamma rays. source: livescience.com
Thanks to Global Content Manager, Matt Tierney, for the images and text that comprise the exhibit element. This is just one of the many exhibits in the gallery at One Market in San Francisco. The gallery is open to the public on Wednesdays from 12 pm to 5 pm, and admission is free. Visit us.
