already.

Since, for some reason, I am trying to blog everyday this month, I thought I'd join them.

Mathematics to me is noun and verb.

*Noun*: it's hard to do better than Eugenia Cheng's description, "the logical study of logical things." Quantities, their properties, operations on them, their properties, treat the operations as the new object and repeat. Pretty soon you have cohomological sheaves and categories dancing with your sugar plum fairies. "Mathematics is beautiful."

*Verb*: reasoning about, playing with, representing or describing mathematical objects or posing or solving the problems and questions that you have about them. "Hey, watch out, I'm doing mathematics over here."

Students first responses:

Milestones:

- Invention of number systems to record quantities, especially place value systems (Babylonians, Mayans, Indians)
- First application problems connected with measurement. (Egyptian and Babylonian stand out to me.)
- Mathematization: the study of the mathematics itself. Greeks, of course. Brahmagupta, Liu Hui, also.
- The Persian synthesis of algebra and geometry. Al Khwarizmi in the House! (House of Wisdom that is.)
- Descartes and the invention of analytic geometry.

Very hard to pick five. Not having Gauss or Euler is painful. But I'm big on synthesis. My favorite modern mathematics is the Atiyah-Singer Index Theorem.

p.s. If you're interested in the course, here's the Google doc of what we did the last time around.

p.p.s. Found this movie poster on this page. Haven't ever heard of this movie, but I'll be looking for it!

p.p.p.s Erin found the movie as released, which lost the cool

*x+y*title.

I just looked up the movie. Apparently the title was changed to "A Brilliant Young Mind", so it might be easier to find that way...although I like "X + Y" significantly better! Also, I'm intrigued by this course you're teaching!

ReplyDeleteThanks, Erin! Here's the IMDB page: http://www.imdb.com/title/tt3149038/

DeleteIt has become one of my favorite courses, so I'm glad it sounds interesting.

I don't think you included the google doc of the course? Would love to see it!

ReplyDeleteOops! Thanks for noticing. http://bit.ly/495-F15

ReplyDeletethank you!

ReplyDeleteIt was released in the cinema as x+y here in Australia at least. Didn't see it though.
