Today we learned about convolution. I researched it and came across this defintion on wikipedia: In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions.

I also found that there are different types of convolution, like circular and discrete.

I also found: It has applications that include statistics, computer vision, image and signal processing, electrical engineering, and differential equations.

I think this last piece of information is particularly interesting considering many of my students will ask me, when will I ever use (some mathematical topic) in real life? While, I find convolution interesting, I know many students (including college students!) who don't have a strong appreciation for math wouldn't. So, I feel that if I'm able to find out how college math, which seems unrelated to the real world most of the time, can be applied in real life, I should be able to find ways to apply other areas of math to my students lives.
