Lead ball vs feather

Lead ball vs feather

Source/Fuente

Galileo Galillei once said that

a cannonball and a feather would reach the ground at the same time if there was no air resistance

At that time demonstrating it was impossible, but I try to prove it, climbed the tower of Pisa and launched two sphere, one lead and another wooden, the same volume to reduce the resistance variable; he knew that by throwing a feather it was impossible that air resistance would not influence his experiment.

It took five centuries for someone to reproduce his experiment and in a unique place; the moon, that time the astronauts of Apollo 15 could verify Galileo Galillei's theory, then the video. (Please refrain from comments that the man did not reach the moon by the terraplanista)

Today thanks to the inexhaustible curiosity of the man and the program Human Universe of the BBC (in the NASA), they returned to reproduce the experiment, with the technology of the moment they could reproduce the necessary conditions.

Thanks to the reason of some men who overcomes the senses, has led and will lead man to discover the secrets of the universe.
