This morning we awoke to find our world covered in soft, cold, white stuff.
The first person to create artificial snowflakes, and figure out why snowflakes grow into the unique shapes that they do, was a Japanese physicist by the name of Ukichiro Nakaya back in the 1930s. You see, Nakaya had a degree in physics, but the only job he could land was at the University of Hokkaido in Japan's far north which did not have any facilities for nuclear research experiments. Hokkaido does have an abundance of snowflakes however! Nakaya studied the crystalline structures using a microscope and camera and worked out how and why they form as they do.

Some flakes trivia: 1) "Films made prior to [It's A Wonderful Life, starring James Stewart] used cornflakes painted white for the falling snow effect. Because the cornflakes were so loud [when tread upon], dialogue had to be dubbed in later. Frank Capra wanted to record the sound live, so a new snow effect was developed using foamite (a fire-fighting chemical) and soap and water. This mixture was then pumped at high pressure through a wind machine to create the silent, falling snow. 6000 gallons of the new snow were used in the film. The RKO Effects Department received a Class III Scientific or Technical Award from the Motion Picture Academy for the development of the new film snow." (IMDb.com)
