Snowflakes that look identical, but may vary at the molecular level, have been grown under controlled conditions. [12] Although snowflakes are never perfectly symmetrical, the growth of a non-aggregated snowflake often approximates six-fold radial symmetry, arising from the hexagonal crystalline structure of ice. [13]
The term "Generation Snowflake" or "Snowflake Generation" was popularized by Claire Fox's 2016 book I Find That Offensive!. The book discussed a 2015 student/faculty confrontation at Yale University between university students and faculty head of college, Nicholas A. Christakis that was recorded and uploaded to YouTube .
The snowflakes were too complex to record before they melted, so he attached a bellows camera to a compound microscope and, after much experimentation, photographed his first snowflake on January 15, 1885. [5] He captured more than 5,000 images of crystals. Each crystal was caught on a blackboard and transferred rapidly to a microscope slide.
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.
