Last Post on Wordpress

Screen Shot 2015-01-19 at 10.10.51 PMHey, I wanted to let everyone know that YofX is moving over to Tumblr. As my blogging style has morphed over the years WordPress has been a tougher and tougher fit. What you can expect on the Tumblr incarnation of YofX is a more visual experience with increased posting frequency–I’m aiming for about one post a day. Here is the URL for the new YofX

and here is the rss with which to subscribe. I hope to see you over there.

Did you know?

Here is a fun fact to demonstrate to your students:

Think of two positive integers.
Add them to get a third number.
Add the second number and the third number to get a fourth number.
Continue in this way until you have 10 numbers.
The sum of the 10 numbers is 11 times the seventh number.

Sheet Music

This is Sheet Music Montage, Coney Island 1950 by Harold Feinstein. I found it via Sad Burro. I’m not sure why, but the patterns and reptitition in this image speak to my mathy sense of beauty

MathChat

mathchat

I’m really excited about the potential of a new app called MathChat. It is an app that allows students to key in problems, start to solve them, and when they get stuck have their peers comment and help. It is kind of a mobile version of the OpenStudy website. A couple of perks: as students work through expressions/equations, MathChat checks their work line by line. It only tells them if it is equivalent or not. The student still has to find the mistake and fix it. Also, MathChat uses the touch capabilities of the mobile environment, so that peers can give you help by writing on your problem. This is a real nice touch. It is early and I haven’t really had a chance to test drive this app with students, but the app holds a lot of promise.

Go Lee Bradley!

One of our own, Lee Bradley, has just written a book called A Programmer’s Guide to the Meaning of Life. Knowing a little about Lee’s eclecticism, this is sure to be a good read. I’m heading to pick up a copy now at lulu.com. Go Tunxis community!

Desmos + Math

I was really blown away with Desmos. They just keep getting better. I found out this week they have apps now for i0S and Android and let you upload pictures. I was trying to figure out the parabola of my smile here. I uploaded my headshot and used a slider to play with the leading coefficient. Looks like I’m y=0.4x^2
