Newton deduced the principles of gravitation after seeing an apple fall.
We don't sell apples, but we do sell wonderful physics kits to help you
teach science in a fun and interesting way. Choose from some of the products

Newton and the Apple
Okay, we all know the story of Isaac Newton getting hit in the head with
the apple, but is this story true? Well, not exactly, but there's more truth
to it than you might think.
Newton grew up on a farm, where he certainly saw many apples fall from
trees. As a young man, Newton recalled those apples and wondered whether
the same force that causes apples to fall would account for the motion of
the moon across the sky.
Newton applied his newly-discovered mathematical technique, calculus
(he called his technique fluxions) to the problem and deduced that,
if his assumption was correct, the moon would orbit the Earth every 29.5
days. That's pretty close to the actual figure of 27.3 days.
So, no, Newton did not get hit with an apple, but he did get hit with a
pretty good idea thanks to an apple.

Comments From Our Physics Customers
The study of physics has scared off many a student. Too bad their teachers
hadn't heard about Maxwell Scientific's quality physics supplies. Read on.
"When I said I was going to teach holography, everyone figured I had busted
the budget. That was before they heard about your excellent hologram
Michael Roussiani. Bismark, ND
"My second graders loved the gyroscopes! And - miracle of miracles - the
gyroscopes survived the encounter."
