WHO MADE AN IMPORTANT DISCOVERY BY FEELING HIS PULSE?
The great Italian scientist, Galileo, made a famous discovery in 1581, while he was still a teenager. While attending services in Pisa Cathedral, a chandelier swinging in the air caught his eye. It seemed that the chandelier always took the same time to swing first one way and then the other, regardless of how far it swung each time.
As there were no accurate clocks in those days, Galileo measured the time of each swing by feeling his pulse and counting the beats. The answer was always the same.
What Galileo had discovered was the pendulum. Using this, it proved possible at long last to build clocks which kept time accurately.
