I’m loving this Youtube channel, Numberphile. It might be a way to try to bring some media into the classroom in a non-boring way. I hope they’ll get students to wonder about math in a more general non-skills based way.

I had a couple of students send this in. I’ve definitely been there myself. Some of the word problems in textbooks really make you wonder (or jump out of a window).

Thanks, Lori and Nilsa :)

Rob Clark sent this trig joke over. It makes me wish Bill Cosby was my math teacher. Just look at that face!

Thanks, Rob.

I just dropped my first single, as my students would say. Check me out. I think with a little auto tune I might be taking over the top 40.

I found this stunning visualization on open culture.

I was presenting at Post’s Shaping the Future Conference last Friday. Post held the conference at the Mattatuck Museum in downtown Waterbury. I had no idea the museum had so many works by Sol LeWittt there. It was sometimes tough to concentrate on online education. Here is a snap of one of the sculptures. It reminded me of one my posts just a few weeks back.

I came across the Miura Fold on Lifehacker. It basically allows one to fold/unfold something with a single motion. The easiest way to think about the value of the Miura fold is in terms of a map. I can’t count the number of maps I’ve screwed up by not folding it back up the right way. Unfortunately it’s fairly hard to learn the fold. I have to build up those origami skills.

I found a sine sink at the Brevard County Zoo on spring break in Florida last week. Need one for my house. That would be the ultimate in math home decor.

Instant reblog. God, I love xkcd! I’ve never been a bumper sticker guy, but this might just turn me.
