I caught a great visualization for Pascal’s triangle on Visualizing Math’s Tumblr.
Whenever I’m teaching the quadratic formula I love telling students that there is a formula “like the quadratic” for cubic and quartic equations, but that after that there isn’t any. They seem amazed by it. I guess because it is still amazing to me. I found a real nice graphic by the mathematical poet with each of the formulas. I’m going to pull this out next time I have that discussion so they can see what the formulas look like.
I’ve been shopping for furniture for the last two weeks. Why won’t my wife take me to a store with math furniture? You might say there is no such thing as math furniture, but you’d be wrong.
The above drawer system is called the fractal 23 by Takeshi Miyakawa.
What can a math teacher find out about math from Twitter? I loved this Deb Costello post. I used to do the same thing before google shuttered real-time search. I loved pulling up “math” at the beginning of my classes to see all the post/updates that rolled in. It was always good for a laugh.
I caught a cute feature about Einstein on NPR. It is a quick 4 minute listen. It should make you feel better the next time you make a sign mistake to know that you are in great company.
I caught an interesting article in Quartz about aspects of American culture that make it a challenging culture in which to learn math. I definitely don’t agree with all their conclusions, particularly about requiring algebra for all, but I agree with the basic observation: the problem of math education has almost nothing to do with the intelligence students.
I caught a really interesting article in Science about researchers using monkeys to try and understand how the mammalian brain represents numbers. Who knew monkeys can do so much math?
My father sent over this great article from the New York Times on using fair division to split up rent with roommates when all rooms aren’t equal. Not only is it a nice application of math that guarantees an “envy free” living situation, but the NYT did a bang up job with the graphics. There is a Wolfram like manipulative and they give you a calculator as well. Well done, NYT!
I would never wished to get mercilessly beat outside a bar, but if I did it would be awesome to become a math savant. Rob Clark sent me a wild story of a man named Jason Padgett. Padgett wrote a book about the experience of going from someone who went from having trouble to a number theorist in a short space of time, Struck by Genius. Thanks, Rob, for sending that my way!
