I'm not going to bother explaining this to anyone - I'm just going to show them this video instead. Couldn't be clearer. Great video!

How lucky we are that they are people like you in this world

Excellent introduction to persistent homology. Many thanks for the links to the relevant papers. [Some of the links are apparently no longer valid, but the valid links are very interesting and informative. ]

Thanks for this extremely accessible video. Quick question, at 8:00 what does the mathematical notation in the Persistent Homology module mean? The circle with a plus sign embedded in it.

From look and tone, it seems like an intro to calculus video. But turns out to be a perfect short explanation of a cutting-edge topic. Bravo!
May I ask what software you used for the animations?
