Kenneth Libbrecht

Kenneth Libbrecht is currently the Executive Officer for Physics at Caltech. He received his Ph.D., at Princeton in 1984. His field is gravitational wave detection and crystal growth.

His research now centers around snowflake formation and propagation. Libbrecht, chairman of the physics department at California Institute of Technology, took the photographs of the snow crystals used for the US Postal stamps in Fairbanks, Alaska; the Upper Peninsula of Michigan; and in Cochrane, Ontario, Canada, according to a press release from Caltech media relations.

Where can the best snowflakes be found?
Libberecht says, "Northern Ontario provides some really excellent specimens to photograph. The temperature is cold, but not too cold, and the weather brings light snow frequently. Fairbanks sometimes offers some unusual crystal types, because it's so cold. Warmer climates, for example, New York State and the vicinity, tend to produce less spectacular crystals."

How to photograph a snowflake
He uses a microscope with a digital camera attached to photograph the snow crystals. He explained the process. "When photographing in the field, I first let the crystals fall onto a piece of cardboard. Then I find one I like, pick it up using a small paintbrush, and place it on a microscope slide. I then put it under the microscope, adjust the focus and lighting, and take the shot. You need to search through a lot of snowflakes to find the most beautiful specimens."

Libbrecht has been studing the physics behind the formation of snow crystals and snowflakes for several years.
