Tides Typo Terminated

The Tides Gizmo had a typographical error. This was fixed this morning. It previously said that the distance from the Earth to the moon was approximately 3 Earth diameters. It now lists 30. Losing a zero really does make a big difference, even if it represents nothing!

"If a nonnegative quantity was so small that it is smaller than any given one, then it certainly could not be anything but zero. To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero."
-- Euler, Leonhard (1707 - 1783)

Thanks to the Curry School at UVA for reporting this bug.
