The title I get when I click on this is, "How (and why) to take a logarithm of an image"

YouTube has A/B testing features that allow videos to have multiple titles and/or thumbnails.

Right. So I thought it would be helpful to share the more-descriptive title that I got.

Clickbait title could use another pass. What is this about?

It's about examining the mathematical methods MC Escher used in one of his recursive drawings.

This would be an excellent title :)

I love 3B1B but generally don't have time to watch long videos. Can anyone sum up the punchline?

One of Dutch artist M.C. Escher's works is a man is admiring a piece of art that itself depicts the building the (very same) man is in [0]. Escher left out the middle bit of the painting, probably since it's fairly complicated, putting his signature there instead. The video itself is about the complex analysis used to fill in that missing middle, based on a paper ~20 years ago.

Depends how you define excellent. If the goal is to get more views then it's not all that great, and views are kind of the point of YouTube for many, especially if they are trying to make a living from it.

That's great for YouTube, but HN has some guidelines:

The whole point is the explanation... it's a bit like someone telling you to take a 2 week holidays somewhere and you'd just say: it's too long, can't someone just get me a plane ticket there and back the same day so I can compress the stay?
