Galileo’s Isochronous Pendulum: Galileo observed a lamp swinging from ceiling at Pisa cathedral ceiling. He was the first scientist to observe how long it took any object suspended from a rope or chain (a pendulum) to swing back and forth. There were no wrist watches at that time, so Galileo used his own pulse as a time measurement. Galileo observed that no matter how big the swings were, as in when the lamp was first swung, to how small the swings were as the lamp returned to a standstill, the time it took for each swing to complete was exactly the same. So, he concluded that the oscillations are isochronous. Anyhow, it was proved by advanced experimentation that the isochronism of simple pendulum is correct within 1% under the 30° of amplitude. It is confirmed that the period changes less than 1% until the amplitude is 30°. On the other hand, the period increased by more than 10% when the amplitude became larger than 80°. At the end of his life he devised a scheme for using a pendulum to regulate a mechanical clock. However, the first reliable pendulum clock was only demonstrated by Huygens 15 years after Galileo's death.

Galileo's Observation of Pendulum Time Period
Galileo was the first scientist to observe the time period of a pendulum. Here's an explanation of why he observed it:

Significance of Galileo's Observation
- Galileo observed a lamp swinging from the ceiling at Pisa cathedral.
- He used his own pulse as a time measurement since there were no wrist watches at that time.

Discovery of Isochronism
- Galileo noticed that regardless of the amplitude of the swings, the time taken for each swing to complete was the same.
- This led him to conclude that the oscillations of a pendulum are isochronous.

Confirmation of Isochronism
- Advanced experimentation later confirmed that the isochronism of a simple pendulum is accurate within 1% under a 30° amplitude.
- The period remains stable, changing by less than 1% until the amplitude reaches 30°.

Impact on Clock Regulation
- Galileo devised a scheme for using a pendulum to regulate a mechanical clock before his death.
- However, the first reliable pendulum clock was demonstrated by Huygens 15 years after Galileo's passing.
In conclusion, Galileo's observation of the time period of a pendulum and his discovery of isochronism were significant contributions to the field of physics and timekeeping.
