WASHINGTON, Jan 21, 2016 -- A huge snowstorm could dump more than two feet of snow all over the East Coast, and that means trillions and trillions of tiny snowflakes. Through advances in crystallography, scientists have learned a lot about the structure of snowflakes. While they all start pretty much the same, once they start crystallizing, it's true that no two snowflakes are alike. In fact, the number of possible shapes is staggering.

There are few musical moments more well-worn than the first four notes of Beethoven's Fifth Symphony. But in this short, we find out that Beethoven might have made a last-ditch effort to keep his music from ever feeling familiar, to keep pushing his listeners to a kind of psychological limit. Big thanks to our Brooklyn Philharmonic musicians: Deborah Buck and Suzy Perelman on violin, Arash Amini on cello, and Ah Ling Neu on viola.
