Video: Can a snow sculpture explain quantum physics?

Few understand the concepts of potential barriers and quantum tunneling, so it follows that trying to illustrate these scientific ideas with a snow sculpture would be futile — but not for chemistry major Sarah Charley ’11 of Portola Valley, Calif., who gamely explains the meaning of a sculpture that she and fellow majors created on Jan. 28.

Around the Quad on Friday afternoon, science students created snow sculptures to illustrate scientific concepts, from evolution to an Erlenmeyer flask experiment gone awry. It was all a prelude to the evening’s Arts Crawl.
