Conservation of Energy: Neat Video

We often talk about the basic principles of physics here, since they are so fundamental to our understanding of the various sources of energy available to us. One particularly important such theory is the conservation of energy, aka the first law of thermodynamics, which says that the amount of energy you put into something is the precise same amount of energy that is available to take out, in one form or another.  It’s the thing that makes perpetual motion impossible.

Now, if that seems like a fairly dry and uninteresting thing, check out the video below, explaining how a physicist and his artist wife team up to create mesmerizing kinetic sculptures.
