Gaileo Galilei : A Herestic ???

Gaileo Galilei (1564 - 1642) was one of the influential scientists of this millenium, however he live during a time when the protestants reformed was gaining momentum and Europe was in turmoil. The Catholic Church was losing its hold on the northern Europe and the Thirty Years' raged. Chinese Proverb quote : " A hero live in wrong time ." Gaileo resided on the Italian peninsula , where the Church maintained a strong hold, and he could not rely on the protection of the reformers in other part of Europe. None-the-less, even though "pagan" belief associated wit frequency and resonance-related phenomena had been banned by the Church for centuries, Gaileo performed research on natural resonant frequencies in a pendulum system. In 1632, Gaileo published his "Dialogue" and a daring move described the mechanics of the natural resonant frequencies writing, " "The Pendulum make its vibrations with one and the same frequency and "every Pendulum hath the Time of its Vibrations...pre-fixed...{and} and it is impossible to make it move under any other Period, than that is natural unto it ." He desribed the resonant accelerating forces produced by precise time puffs of his breath stating, "by blowing upon {the Pendulum one may} confer a Motion, and a Motion considerably great by reiterating the blasts, but only under the Time properly belonging to Vibrations.". Gaileo thus provided one of the first documented description s of resonance, namely the increase in amplitude and energy of a system of vibrations when an applied vibration , motion or energy matched the natural frequency of the system. Unfortunately, the Church was less accommodating than Gaileo had anticipated. He was convicted of heresy and placed under house arrest for the rest of life. Sigh!!!
