In case you haven't heard about it yet, there is a new education app for iOS and Windows Phone devices called PhotoMath. Most basically, the app utilizes the camera on your device to recognize numbers and letters, runs an algorithm, and then displays a solution on the screen. From there you can follow the solution it generated step-by-step.
Here it is in action.
There are two ways to
Tape. It is not allowed. Origami models are traditionally made with one piece of paper (see Robert Lang‘s site for some amazing examples) that is only folded – never glued, taped, or cut. Modular origami follows the same rules – no glue,… Continue reading →

Penrose tilings are an example of the non-periodic tilings discussed in the last post. Recall that these are tilings that cover the entire infinite plane leaving neither gaps nor overlaps. Whats nice about these tilings is that the set of tiles used to construct the Penrose tilings only consists of two different basic shapes consisting of quadrilaterals.
Whats even more remarkable about Penrose tilings is that using just
I taught the Mathalicious Domino Effect lesson today. It was awesome. First, the lesson is free. Check it out here! I’m in the middle of a unit on linear equations, but it could be used as an intro with same basic background knowledge just as well. The lesson: The lesson has three main parts. First, it gives […]
