SULL'ISOCRONISMO


When he became interested all'isocronismo?

My first interest in the pendulum was a time I was in the Cathedral of Pisa for a religious function. As my mind distracted followed the long sermon, I saw a priest holding a candlestick. The chandelier hung from the ceiling by a long rope and the priest pulled him aside. When he finished the sermon, the priest left that the chandelier began to sway. I looked at him and began to consider the time it takes to make a swing full circle. To measure time, swing sfruttai the beat of my wrist, and while the oscillations gradually decreased in size, I made an amazing discovery: he had the same swing every time, even though each had a width less than the previous year. Not sure what the eyes and the pulse of the wrist were proving to me, I ran home to repeat what I had seen in the Cathedral. Semplificai the experiment by replacing the chandelier a pendulum, a simple small weights tied to a string. What he discovered in 1602? In 1602 I made the greatest discovery about the pendulum. I discovered that the time of oscillation depends on the extent of the arc is not completed (isochrone). I found out by producing two pendulums of equal weight with different initial elongation, and counting the number of complete oscillations in the same period of time. To my amazement I saw that the pendulum with an initial elongation of 5 degrees had the same period of oscillation with the initial elongation of 45 degrees.

She is really a genius! I wonder how many people will be taught these things?

"We can not teach anybody anything, but we can help everyone make their own discoveries. In scientific matters, the authority of thousands of people worth the humble reasoning of a single individual. "
