1602 – Galileo made an important discovery to provide the basis of future work while in Pisa at University.
Oscillating movement, back and forth, like a pendulum “measures” an interval of time. The discovery was, time intervals were not dependent on the arc of the swing (isochronism). This lead to the creation of the pendulum clock.
A student of Greek philosophers, he argued Aristotle’s beliefs on Physics, and later proved that all objects, regardless of their density, fall at the same rate in a vacuum.
He invented a telescope and proved the Copernican System and disproved long-held beliefs that the Earth was geocentric. This obviously lead him to be in trouble with the Catholic church, whose main head-quarters are in the Vatican (Rome, Italy).
Leonardo de Pisa, a.k.a. Fibonacci, was born in Italy around 1175. He is accredited with the indentification of a series of numbers, or sequence which is apparent in nature.
To obtain each number of the series, you simply add the numbers that came before it. In other words, each number of the series is the sum of the numbers preceding it.
This essentially is bringing order from chaos. Order being form, chaos being dysfunction. This is the base for the numeric system, trigonometry, sacred geometry, binary evolution, technology advancement, understanding symbols and physics.
