Shake a metal plate covered in sand at certain frequencies and mysterious patterns appear. The demonstration, published in 1787 by Ernst Chladni, illustrates a concept known as "fundamental modes of vibration." Jon Jacobsen, a mathematician at Harvey Mudd College, explains why the experiment still captivates scientists and students today.
