*This is another post in my series on math in the real world.*

Vi Hart explains much of the mathematics behind noise in great detail, so watch her awesome video below. Thanks to @delta_dc for sharing it with me.

Notice her use of Audacity? I think we could quite easily turn this into a lesson plan… perhaps related to fractions, or to sine and cosine waves.

I’ve been playing with the idea of connecting math and music together into a unit. It’s a really rich field, and incorporates lots of different mathematical topics, not just those of sinusoidal functions. I gave talks at pre-calculus conferences held at Rutgers in 2010 and 2011 on this idea; if anyone out there is interested in receiving the two PowerPoint presentations from my talks, please e-mail me (michael DOT r DOT thayer AT gmail DOT com)!
