how did galileo?

Question

come up with the idea or the law of the pendulum

Answer 1

Galileo was one of the first "Experimentalists". Prior to Galileo most science or natural philosophy as it was known then relied upon earlier conjectures passed down from the early Greeks, specifically Aristotle.

Galileo sought to actually observe what really happened by performing experiments. In devising his law of pendulums Galileo actually observed swinging pendulums of different masses and lengths and recorded his observations.

The patterns that emerged from these observations became codified into his "Law" of the pendulum; really a mathematical system for predicting the behavior of a pendulum.

Answer 2

GALILEO GALILEI (1564-1642)

Here is a list of Galileo's most famous discoveries.

1. The law of the pendulum.
According to a story that is probably not true, during a particularly boring mass in the Pisa Cathedral (a beautiful building that still exists, next to the famous Leaning Tower), Galileo noticed that an overhead lamp, hanging from a long chain, swung back and forth at regular intervals. He timed the oscillations against his pulse and determined that they were remarkably regular. Later, he was able to formulate pendular motion with mathematical precision. Today, we write the law of the simple pendulum thus: T = 2p ./ (L/g).

Answer 3

In the mid-1600s, Christiaan Huygens, inventor of the pendulum clock, empirically confirmed Kepler's proposal.

Apparently Galileo had nothing to do with it.
