|This telescoping Java applet illustrates powers of ten. View the Milky Way at 10 million light years from the Earth, move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree -- then 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. With a primer of exponential notation, a downloadable screensaver, and a classroom activity on microscopy.|
