Why Van Gogh's "Starry Night" Is Actually An Art Of Science
AdultsArtSciencePhysicsPhysicist Werner Heisenberg said, "When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first." As difficult as turbulence is to understand mathematically, we can use art to depict the way it looks.
