Okay lets get away from trucks for a few minutes and look at something else..........
The Universe..................
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.
I love this interactive Java, let the thing run then you can zoom in and out as is your want. Sort of makes you feel a little insigificant in the big scheme of things..............
