Timeline of snowflake research

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The hexagonal snowflake, a crystalline formation of ice, has intrigued people throughout history. This is a chronology of interest and research into snowflakes. Artists, philosophers, and scientists have wondered at their shape, recorded them by hand or in photographs, and attempted to recreate hexagonal snowflakes.

Chronological list[edit]

BC to 1900[edit]

1901 to 2000[edit]

2001 and after[edit]

  • 2002 - Kazuhiko Hiramatsu (平松和彦?, Hiramatsu Kazuhiko) devises a simple snow crystal growth observatory apparatus using a PET bottle cooled by dry ice in an expanded polystyrene box.[18]
  • 2004 September - Akio Murai (村井昭夫?, Murai Akio) invented the apparatus named lit. Murai-method Artificial Snow Crystal producer (Murai式人工雪結晶生成装置) which makes various shape of artificial snow crystals per pre-setting conditions meeting to Nakaya diagram by vapor generator and its cooling Peltier effect element.[19][20]
  • 2008 December - Yoshinori Furukawa (吉川義純?, FurukawaYoshinori) demonstrates conditional snow crystal growth in space, in Solution Crystallization Observation Facility (SCOF) on the JEM (Kibō), remotely controlled from Tsukuba Space Center of JAXA.[21][22]
