Little Big Pictures

This page contains early efforts of software for mobile devices. All of the content on this page is programmed using Javascript and the HTML5 canvas. Thus, it should function on desktops, tablets, and smartphones with browsers that support the HTML5 canvas. The code has been extensively tested on the iphone and android devices. However, it is not possible to test the code on every mobile device and each has its own ideosyncracies.

The modules provided here are termed "little big pictures" since they focus on a central concept in astronomy, yet are small enough to run on a smartphone. They consist of a simulator, background information, and exercises to be completed in the simulator. The content here will likely be in a state of flux for a while as it is being fine-tuned. We would appreciate feedback.

Coming Soon: more expansion of the universe, lunar phases.
