Black holes sound wildly complicated. After all, there are all sorts of bizarre things going on: intense gravity, the warping of the fabric of space, the distortion of time itself. But when it comes to describing black holes, it comes down to just two numbers: the mass of the black hole and its spin. That’s right. Everything you physically need to describe a black hole is found in just these two numbers.

Chip Clark came to the Smithsonian's National Museum of Natural History in 1973, with a degree in biology and an interest in photography. He has been a photographer on staff ever since, documenting thousands of specimens and exhibits, and accompanying scientists on research trips around the world. He died June 12, 2010. This video interview was made by Lauren Dare, an intern with the Smithsonian Institution Archives, on May 27, 2010, as part of an oral history project for the National Museum of Natural History's Centennial (2010-2011). To learn more about Chip Clark, see his page on the Centennial website-- www.mnh.si.edu/onehundredyears/profiles/Chip_Clark.html -- where you also can find more videos and stories about the people and the work of the NMNH.
