The World’s Hidden Equations

Looking for some history and explanations, using every day language, of some of the concepts you’re learning in engineering?  Here’s a cool 3 minute video about:

  • The Wave Equation – the acceleration of a point on a vibrating string is proportional to the string’s tension – led to the development of radio
  • Maxwell’s Equations – calculate electric and magnetic fields, the change in an electric field causes a magnetic field, and vice versa – applies to radio waves, x-rays, visible light
  • the Fourier Transform – any wave, no matter how complicated, can be broken up into a combination of simple sine waves – used to compress digital photos and more!
