This is cool
Just had this forwarded (is that a word?) to me by a friend, she, quite rightly, stated in the subject line of the email that “This is cool”. Indeed it is. I think it did the rounds a while ago but I didn’t check it out first time around.

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.”
