Leonardo da Vinci's centuries-old sketches reveal he may have understood key aspects of gravity long before Galileo, Newton and Einstein.
would expand on that to develop a law of universal gravitation, describing how objects are attracted to one another," according to the statement."Da Vinci's primary hurdle was being limited by the tools at his disposal. For example, he lacked a means of precisely measuring time as objects fell."Some of da Vinci's sketches show triangles created by particles pouring out of a pitcher when moved along a straight path parallel to the ground.
One of da Vinci's sketches detailing an experiment involving pouring water from a pitcher to help understand the effects of gravity. "What caught my eye was when he wrote 'Equatione di Moti' on the hypotenuse of one of his sketched triangles — the one that was an isosceles right triangle," Mory Gharib, lead author of the study and professor of Aeronautics and Medical Engineering at Caltech, said in the statement."I became interested to see what Leonardo meant by that phrase."
When analyzing the sketches, the researchers had to translate da Vinci's Italian notes, which were written in his famous left-handed mirror writing that reads from right to left. The researchers then used computer models to replicate da Vinci's experiments. , and that as the particles fall, they are no longer influenced by the pitcher, but instead accelerated by only gravity pulling them downward. However, he was unable to formulate his observations into an equation at the time.
"What we saw is that Leonardo wrestled with this, but he modeled it as the falling object's distance was proportional to 2 to the t power [with t representing time] instead proportional to t squared," Chris Roh, co-author of the study and assistant professor at Cornell University, said in the statement."It's wrong, but we later found out that he used this sort of wrong equation in the correct way.
