If you love math and science as much as I do, you'll enjoy Powers of Ten, a short video produced almost three decades ago by Charles and Ray Eames that wisks you away from a picnic in the park to the outer limits of the universe, and back down into the microscopic world as seen in a man's resting hand.
The video takes you to both places by zooming out at 10 times 10 meters every 10 seconds until the universe is visible. The second half zooms downward even faster to the universe inside the human body.
