A new study examining some of Leonardo da Vinci's sketches in the Codex Arundel reveals the artist calculated the earth's gravitational constant at a 97% accuracy rate.

Earth's oceans have topographic features and are held down by gravity, not contained by a giant Antarctic ice wall. Hotspots ranked Start the day smarter ☀️ Funniest cap messages Get the USA ...

A diagram of the proposed Underground Gravity Energy Storage system. Hunt, et al. Just because a mine has been exhausted of its ore, that doesn't necessarily mean it has no value.

In other words, gravity may not need to be as complicated as we’ve made it—at least, mathematically speaking. A key term in this research is normalization, or renormalization.

Instead of looking at the gravitational force and torque on all the individual masses in the crane plus tank system, I can just look at the center of gravity. Here is a diagram showing the forces ...

Gravity, or gravitational attraction, is the tendency of mass to gather toward itself, drifting together even across great distances due to curvature in spacetime.

A spacetime diagram of its trajectory is a parabola that starts 45 meters above the ground, and hits the x-axis (time axis) three seconds later. But three seconds in time is 3 x 300,000km, or nine ...

A recent study from the California Institute of Technology examined diagrams in da Vinci's notebooks that had been long forgotten about. These notebooks, which have now been digitized, show ...

This is a great question. It comes up quite often. If you ask the people around you, there are two common answers: Astronauts float around in space because there is no gravity in space. Everyone ...
