Particles In A Solid

Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.

The Ball in a Wedge model displays a ball confined to move between two walls that form a wedge shape. The ball undergoes elastic collisions with the walls of the wedge. The angle of the wedge can be changed by setting the angle with the text box or dragging one of the wedge walls. By clicking in...

Wiki in a Jar is a small (one jar file, Why? To reveal the power of plain text. Plain text files can be opened with almost any editor and by keeping the markup simple it is very easy to transform the content to any other desired format even after years, when the original editor is not available...
