Nicolaus Copernicus
1473-1543, Polish astronomer, believed that
the Earth revolved around the Sun, This agreed with Aristarchus and disagreed with Ptolemy. His
conclusion was based on his work charting planetary motion and it would be
confirmed later by Galileo.
Galileo
1564-1642 was born in Pisa Italy, moved to Florence in 1570, was schooled in a
monastery and admitted to Medical School in 1581. He was drawn to pursue
Mathematics and Aristotelian philosophy and lectured in 1585. He designed a scale to measure small
quantities. He studied and lectured on motion, gravity and mechanics. He became
a fan of Archimedes and Chaired Mathematics at Padua University from 1592 to
1610. He subsidized his own research by selling his compass and tutoring
students.
Galileo
developed the scientific method requiring proof of theories through
experimentation. Galileo’s insistence on measuring incorporated mathematics as
the language of science. His early work in Physics established the law of
gravity in 1609.
The
telescope was invented by Dutch eyeglass maker Hans Lippershey in 1608. Galileo improved the telescope in 1611 and
began to publish his discoveries in astronomy.
His study of the movement of planets convinced that the earth revolved
around the sun. The Bible didn’t take sides, but the Church interpreted in
Genesis that the sun revolved around the Earth. He published his observations
in 1632.
Isaac
Newton 1643-1727, English physicist, mathematician and astronomer followed on
Galileo’s work. He entered Cambridge in 1661 at age 18 and became Professor of
Mathematics in 1669 at age 26. He was elected to Parliament in 1689, became
Master of the Mint in 1699 and was knighted in 1705. He experimented and published in optics,
mechanics, gravity, chemistry and physics. He advanced mathematics. He
continued the scientific method and established proofs.
Albert
Einstein 1879-1955, published his gravitational field
equations
of general relativity in 1915. He was
interested in the natural phenomenon that was not yet known or proven using the
scientific method of proving theory using mathematical equations. He was only
interested in answering the hard questions.
He was interested in light, how fast it traveled and what it was made
of. Now that the dual nature
of light as "both
a particle and a wave" has been proved, its
essential theory was further evolved from electromagnetics into quantum
mechanics. Einstein believed light is
a particle (photon)
and the flow of photons is a wave.
He was interested in gravity in space and how to measure it and prove his
equations. He was interested in gravitational radiation, radio signals and
electromagnetic science. He was interested in space and time and the nature of
space and its ability to curve. He was interested in energy and its
relationship to matter and concluded E=MC2.His work enabled others to develop radar,
wireless communications, optical devices, nuclear power, space travel and further
understanding of atoms.
