A pendulum is an object or weight suspended from a pivot point. When a pendulum is set in motion, gravity causes a restoring force that will accelerate it toward the center point, resulting in a back and forth swinging motion. The word "pendulum" is new Latin, derived from the Latin "pendulus," which means "hanging." Pendulums were used in many historic scientific applications.
Dutch scientist Christiaan Huygens built the first pendulum clock in 1656, increasing timekeeping accuracy from 15 minutes to 15 seconds per day
n 1818, Henry Kater devised the reversible Kater's pendulum to measure gravity, and it became the standard measurement for gravitational acceleration over the next century.

On the left, a symbolic figure of the Wind grasps a sundial and compass. Calm is shown to the right, holding a modern sextant. The moon orbits diagrammatically around the two figures. At the top is an astrolabe, an early astronomical instrument.

Johannes Hevelius with one of his telescopes (from Selenographia, 1647, an elaborate map of the moon). Hevelius, who lived in Danzig, Poland, built one enormous telescope 150 feet long. he also published an important star atlas. (No drawing or engraving records Galielo's telescopes, and the two of his manufacture which survive are not as powerful as the one he was using in 1610/11. Thus we do not know what this own astronomical telescope looked lime)

Vegetation is really controlling what happens . . .
whereas the emphasis in the climate models
has always been on the atmosphere.

From Hollywood
A century-old record was broken in downtown LA as other areas got as much as 5 inches of rain. ~ Dec 2021
