Snowflake physicist's photographs to be featured on 2006 postage stamps

Postage rates may keep going up, but when it comes to natural beauty and scientific wonder, one particular issue of stamps is going to be hard to lick.

Beginning next October, the U.S. Postal Service will issue a set of four commemorative stamps featuring images of snowflakes furnished by that hotbed of snowflake research, the California Institute of Technology.

The holiday snowflakes stamp set will display photographs taken by Caltech physics professor Kenneth Libbrecht.
