Grant Sanderson has released another excellent video, this time on the subject of [convolution](https://www.youtube.com/watch?v=KuXjwB4LzSA).

I am regularly impressed with the lucidity of his explanations. If you are interested in mathematics at all, you are probably already aware of his videos, but it doesn't hurt to highlight his work again and again.
