The random, symmetrical beauty of snowflakes has been recreated in a computer program, U.S. researchers said on Tuesday.
It took four years for two mathematicians from the University of Wisconsin, Madison, and the University of California, Davis, to develop the computer model’s theory and perform the computations.
“Even though we’ve artfully stripped down the model over several years so that it’s as simple and efficient as possible, it still takes us a day to grow one of these things,” Wisconsin researcher David Griffeath said in a statement.
