Scientists have studied Leonardo da Vinci’s early sketches: he understood gravity before Galileo and Newton

Scientists from the California Institute of Technology analyzed the sketches in da Vinci’s notebooks, which are more than five centuries old. The drawings show that the author understood the phenomenon of gravity even before Galileo, Newton and Einstein. This is reported by Space.com. Da Vinci conducted experiments in the early 1500s with falling particles of a jar and described the acceleration of the fall. “It wasn’t until 1604 that Galileo Galilei theorized that the distance traveled by a falling object was proportional to the square of the elapsed time, and it wasn’t until the late 17th century that Sir Isaac Newton extended this to develop the law of universal gravitation, which describes how objects are attracted to each other,” the statement said.

The artist and scientist recorded and schematically described his experiments. He drew triangles on which he showed the interdependence of movement and fall. The sketches also showed that if the pitcher’s motion is accelerated at the same rate as gravity, it creates an equilateral triangle that da Vinci identified as the “Equatione di Moti,” meaning “equalization (equivalence) of motions.” The researchers analyzed and translated the sketches and then used computer models to recreate da Vinci’s experiments. Da Vinci’s notes acknowledge that the velocity of the falling material is accelerated downward, but that their fall is not affected by the jug. However, at the time he was unable to formulate his observations into an equation. “He modeled it as the distance an object falls is proportional to 2 to the power of t [де t означає час], and not proportional to t squared. It’s wrong, but later we found out that he correctly used such an incorrect equation,” says study co-author Chris Roe. While simulating the water vase experiments, the team discovered the same mistake that da Vinci made several centuries ago. Scientists believe that a very progressive and non-standard vision that was far ahead of its time.
