For those who (like me) are constantly amazed by the scale of our universe… try this site.
“View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.”
Mike, if you havn’t seen the movie “Powers of ten” by Ray and Charles Eames, go get it. This is the movie where this idea came from and it is just awesome - and your kids will love it too.
