Color Uncovered Free App for the iPad

In his Ted Talks video "Eye vs. camera" Michael Mauser outlines the similarities and differences between your eye and a video camera. He shows us that your eyes don’t always capture the world exactly as a video camera would. But the eyes are remarkably efficient organs, the result of hundreds of millions of years of coevolution with our brains.   Exploratorium’s Color Uncovered iPad app provides a good introduction or follow-up to the TED-Ed lesson Eye vs. Camera. Explore the surprising side of color with Color Uncovered, an interactive book that features fascinating illusions, articles, and videos developed by the Exploratorium.

Desmos - A free Graphing Calculator

Desmos - A Graphing Calculator for iPad, Android, and Your Browser

Desmos is a free graphing calculator that has been available for a few years as a browser-based tool and as an iPad app. Late last month Desmos launched a free Android app. The Desmos calculator performs all of the functions you would expect to see in a graphing calculator with a couple of extras that you don't find in typical graphing calculators. Desmos allows you to share your equations and graphs. Desmos graphs your equations as you type them and redraws them as you alter your equations. See some of the best features of Desmos in the videos embedded below.
