If you’ve taken a good art history course on the Impressionists and Post-Impressionists, you’ve inevitably encountered Vincent van Gogh’s 1889 masterpiece “Starry Night,” which now hangs in the MoMA in New York City.

Van Gogh’s impasto technique, or thickly applied colors, creates a rhythmic effect—the picture seems to constantly move in its frame.” Artistically, van Gogh managed to capture movement in a way that no artist had ever quite done it before. Scientifically, it turns out, he was on to something too. Just watch the new TED-ED lesson above, The Unexpected Math Behind Van Gogh’s “Starry Night.”
