Thanks to Ed Kellogg for this interesting video link (Times Tables, Mandelbrot and the Heart of Mathematics by Mathologer) and his comments: “This looks like a real treasure trove to me! And not just Mathologer – looks like a lot of other mathematicians or mathematics enthusiasts have put up some great videos since the last time I checked out this area on YouTube! Visually entertaining and illuminating videos illustrating mathematical concepts and processes used to seem almost as rare as hens teeth – nice to see how much that situation has improved.” … I agree, Ed… Looks like I’ll want to spend more time exploring more of his – and related – videos! :-)
