This document discusses the importance of physics and provides examples of its impact. It describes how physics has revolutionized transportation, communication, entertainment and more from the past to present and will continue to do so in the future. It then profiles several famous pioneers and discoverers in physics throughout history, including Galileo, Aristotle, Copernicus, Kepler, Newton, Archimedes and more modern figures like Einstein, Tesla, Millikan and Stern. It emphasizes that physics has proven itself as a pioneering science that has shaped our lives and world.

Do you know how long it took
Magellan to reach the Philippines from
Spain?
 Almost two years.
That was about 500 years ago.
Today, you can travel the same

Some Pioneers and Discoverers of
Physics…Galileo Galilei is an Italian physicist and astronomer. Galileo
maintained that the earth revolved around the sun, disputing
the belief held by the Roman Catholic church that the earth
was the center of the universe. He refused to obey orders
from Rome to cease discussions of his theories and was
sentenced to life imprisonment. It was not until 1984 that a
papal commission acknowledged that the church was wrong.
Aristotle. Known to medieval intellectuals as simply “the
Philosopher,” Aristotle is possibly the greatest thinker in
Western history and, historically, perhaps the single
greatest influence on Western intellectual development.

Some Pioneers and Discoverers of
Physics…Polish astronomer Nicolaus Copernicus revolutionized
science by postulating that the earth and other planets revolve
about a stationary sun. Developed in the early 1500s but not
published until years later, his heliocentric (sun-centered)
theory disputed the Ptolemaic theory, popular at the time, which
held that the sun and the planets revolved about the fixed earth.
Copernicus at first hesitated in publishing his findings because
he feared criticism from the scientific and religious
communities. After suffering initial disbelief and rejection,
however, the Copernican system ranked as the most accepted
concept of the universe by the late 17th century.
Johannes Kepler believed that the Copernican
heliocentric view of the solar system, which held
that the earth rotates around the stationary sun,
was correct. Kepler formulated an accurate
mathematical description of planetary orbits that
gave mathematical rigor to the heliocentric model.

Some Pioneers and Discoverers of
Physics…Isaac Newton’s work represents one of the greatest
contributions to science ever made by an individual. Most
notably, Newton derived the law of universal gravitation,
invented the branch of mathematics called calculus, and
performed experiments investigating the nature of light and
color.
Archimedes discovered the principle of
water displacement while taking a bath.
He also developed simple machines
such as the lever and screw into useful
tools for war and irrigation.

Some Pioneers and Discoverers of
Physics…
Blaise Pascal is noted primarily as a
mathematician, scientist, and author.
Dutch-born Swiss scientist Daniel Bernoulli
was a pioneer of the study of how fluids
move. He formulated Bernoulli’s principle,
which states that a fluid exerts less
pressure as it moves faster, and vice
versa.

consultant for
the Manhattan
Project during
World War II,
helping to
design the

Nikola Tesla
Inventor of the

Albert Einstein is
considered one of the
greatest and most
popular scientists of
all time.
Robert A. Millikan
conducted a series of
experiments that
measured the electrical
charge carried by an
electron.
Otto Stern developed a
method for studying the
magnetism of atoms,
atomic nuclei, and
protons.
