Engineers from the California Institute of Technology (Caltech) have discovered that Leonardo da Vinci’s understanding of gravity is centuries ahead of his time. In a paper published in the journal Leonardo, the team looked at one of Vinci’s notebooks and found that the famous scientist devised experiments to prove gravity was a form of acceleration. He even modeled the gravity constant with an accuracy of about 97%, Phys.org reported on Feb. 13. Notes of Leonardo da Vinci’s gravity experiments.

In most cases, passenger planes will fly at more than 9,144 meters , according to John Cox, a former commercial pilot and director of the consulting firm Safety Operating Systems . Planes can reach heights of 12,192 – 12,496m, but that is relatively rare. Tom Adcock,…
