haha what the fuck? Is this a professor somewhere?

ITT other weird math shit you've found on youtube.

I see that a lot too. I don't believe it's inherently a bad thing though, at least not when the material is used as supplement. On the contrary, I think that in some cases it's a very good thing. Specifically with courses where one benefits from having access more examples and visual intuition such as this:

This lecturer makes a point that someone learning mathematics should ideally have more theorems than definitions and more examples than theorems (but that unfortunately most textbooks are written the other way around).

In general though I think modern technology gives us access to new ways of teaching mathematics that we should try to embrace.

There's a mathematician named Ralph Abraham. He founded the visual math institute (though it seems to be more or less defunct). Anyway, the guy was a big proponent of visualization and tried to design a standard way of demonstrating visual arguments in a textbook (the same way that one demonstrates them on a blackboard). Unfortunately I think he patented or something but last time I looked at it it gave some pretty sensible criteria. Anyway he wrote a big book of visualizations for dynamic systems theory (diff eq, chaos theory, other junk).

http://www.amazon.com/Dynamics-Geometry-Behavior-Ralph-Abraham/dp/0201567172

The book illustrates what I mean by depicting arguments in text in a way analogous to how they're depicted on a blackboard.

I don't think that youtube is necessarily the future, but I do hope some changes are coming our way.

>>	Anonymous Tue Dec 22 04:18:13 2015 No.7737496 >>7735465 Hell yea, he's the shit. He's funny too. Come to think of it I haven't seen any other math lecturers on youtube that draw lots of stuff like this guy.
