There are now an increasing number of resources to be found within the Physics area. There are notes and past paper questions. For the past paper questions I have written expansive answers that I hope will be a better aid in exam revision than just mark schemes.
I have recently discovered Processing, a tool that can be used to create animations. I'm hoping to make some of these soon, and make them available here. The first are a couple of animations of waves.
