My classes quickly learn that I am easily side-tracked by interesting math ideas and conversations. This VSauce video was sent to me by a student and I felt compelled to share it with the rest of the class. In the last two years, we have tackled the concept of infinite, on multiple occasions. This video does a tremendous job of simplifying this abstract and complex idea. Our brains were stretched and I loved the interesting ideas it generated in class. I hope if you are interested in learning more, you will check out the links on the YouTube page and the many books referenced at the end of the video.
