How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research -- for example in nuclear fusion research, when the walls of the ...

Isaac Newton would never have discovered the laws of motion had he studied only cats. Suppose you hold a cat, stomach up, and drop it from a second-story window. If a cat is simply a mechanical system ...
