Science Friday Science Club: chladni 041709
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. https://www.youtube.com/watch?v=k_rCL0r4OAo
