Galileo And Me

Scientific legend has it that a young Galileo Galilei conducted an experiment that helped to define some of the properties of gravity. In order to test Aristotle’s notion that objects fall at different rates according to their weight, Galileo is reputed to have taken two balls with materially different weights to the top of the Leaning Tower of Pisa and dropped them simultaneously. According to the story, the balls fell to the ground below at the same rate of acceleration and landed at the same time — thereby showing that Aristotle was wrong and the invisible force of gravity acts equally on objects with different masses. Galileo’s findings still hold up — even when modern-day scientists test the effects of gravitational acceleration at the atomic level.

I conducted my own impromptu experiment with gravity yesterday morning, and can attest that gravity is still out there, working the same way it always has.

I was just starting my morning walk. We had been subjected to the dreaded “wintry mix” overnight, and the footing was treacherous. The parking lot at the corner had been cleared of snow and looked to be dry and safe, so I decided to take a short cut through the parking lot. As I proceeded with a jaunty step across the lot, my right foot hit a patch of black ice, my feet shot out to the left, and I landed hard on the asphalt surface on my right side. I gingerly picked myself up, checked to make sure that I was in one piece, then carefully made my way back to our house, figuring that the wise course would be to skip any further icy adventures that day. Fortunately, I had on several layers as well as my own more than ample personal padding, no bones were broken, and I’m sore, but not badly bruised.

It’s the first time I’ve fallen to the ground in a while, and it got me to thinking how amazing gravity is. I probably fell no more than a few feet, but I struck the pavement with breathtaking (literally) force, as if one of the Ohio State linebackers had hit me at full speed and laid a crushing blow on my right side. The experience made me think that I need to be a lot more judicious about walking during the winter, because gravity is always out there, brooding and ready to yank you down.

I’m just grateful I wasn’t falling from the top of the Leaning Tower of Pisa.
