    My word. He’s covered 50% of my entire knowledge base of infinite sets (I think the other 50% is the proof that you can always create a bigger set with the set of subsets of that set). Not only that but he’s done it in 7 minutes and has done it infinitely better then I ever could – that was great!

  2. Loved this TEDx. Timely as well as we were discussing ideas around infinity in our grade 8 class. I am going to see how well students grasp this video. It certainly brings back some ideas of set theory I studied in university but seems much more concise and easier to understand. Thanks for sharing.
