Mathemagician Vi Hart Explains the Science of Sound, Frequency and Pitch
By Maria Popova
You may recall mathemagician Vi Hart from her brilliant stop-motion explanation of the Victorian novella Flatland on a Möbius strip. This month, she’s back with another gem, this time exploring the science and mathematics of sound, frequency and pitch. From Pythagoras to the anatomy of the ear, Hart uses her signature playful hand-illustrations to reveal how simple mathematical ratios make pleasing melodies.
