One Night... Down in the Snow Lab

Although no two snowflakes are exactly alike, physicist Ukichiro Nakaya recognized that they have basic structures. He created the first system to classify snowflakes, and divided falling snow into 41 individual types.

Trained as a nuclear physicist, Nakaya was a professor in Hokkaido, the North Island of Japan - where there were no facilities for nuclear research. However, there was plenty of snow, so he turned his attention to snow crystals. (Hey, it's better than working on bombs!)

Professor Nakaya was also the first person to make artificial snow (1936), starting a process that extends the seasons of ski hills worldwide.

Today, the Ukichiro Nakaya Museum of Snow and Ice is located in Nakaya's hometown of Katayamazu, Japan.
