Tenía el archivo de voz (mp3) y lo he manadado traducir de voz a texto (en español) y me ha producido esto, que me da que no es un buen castellano.
Today I am going to talk about the concept of gravity that Leonardo da Vinci had. Aristotle is a figure who made great contributions in many fields, including science, but he was wrong about many things. The serious issue is not that he was mistaken, but that for many centuries it was believed that if Aristotle said it, it was dogma of faith. The concept of gravity that Aristotle had was strange and extremely erroneous. For him, objects fell because they tended to occupy their natural place in the universe. Heavy objects tended to go to the ground, to the earth, as that was their natural place. While this is aberrant and wrong, the most serious thing is that he believed that the speed of fall was proportional to its weight. That is, a heavier body fell faster than a lighter one. This error persisted throughout the Middle Ages and really until Galileo. On some occasions I have said that Galileo's great triumph was to question Aristotle, to show that he was wrong, and that the fall of bodies was an acceleration independent of their weight. The surprise has been that Morteza Garib, from the California Institute of Technology, reviewing Leonardo da Vinci's work called the Arundel Codex, discovered that the great Leonardo had already conducted experiments and had demonstrated that gravity was an acceleration and independent of the weights of objects. He tried to find mathematical formulas to describe it, but he did not succeed. That merit we owe to Isaac Newton. This fact makes me think of a fundamental characteristic of science, the need to publish discoveries. If Leonardo, instead of keeping his discovery hidden, written in his characters, opening quotes, secrets, closing quotes, had published it openly, today we would consider that the one who defeated the existing dogmatism against Aristotle was not Galileo, but Leonardo. That's all, until next time.
