Isaac Newton

The Principia (1687)

Provides the formulas for the mechanics of the universe

Isaac NewtonHow does Isaac Newton’s Principia relate to our ability to go to leave the Earth’s atmosphere and

explore outer space?

Universal law of gravitation: law

that explains why the planetary

bodies do not go off in straight

lines but instead continue in

elliptical orbits around the sun!

•Objects are attracted to each other by the force of

gravity.

This is Isaac Newton’s most famous quote. What does it reflect about his

personality?

Source: Isaac Newton. English Scientist. Letter to Robert Hooke. February 5, 1676

“What Descartes did was a good step. You have added much several ways, and especially in taking the colours of thin plates into philosophical consideration. If I have seen a little further it is by standing on the shoulders of Giants.”

Now, Consider the Robert Hooke had many physical deformities, including a very small

stature, and had recently criticized Newton’s theory of light.

Newton’s Cultural Impact

Nature and Nature's laws lay hid in night: God said, "Let Newton be!" and all was

Poet. Epitaph intended for

Isaac Newton

EventuallySOMEBODYwill discoveranomalies in

the Newtonian model of the

universe, as well. Another paradigm

shift will occur.

Medicine and Chemistry

Medicine in the Middle Ages was based on Galen’s investigation.

Greek, 2nd century A.D.

Observations made on animals

Vesalius also made new discoveries by

dissecting the human body

Arteries and veins

William Harvey1578-1657

Wrote On the Motion of the Heart and Blood.

Heart was the beginning point of the circulation of the body.

Same blood in veins and arteries

Circuit

Robert Boyle1627-1691

One of the first Chemists

Conducted experiments

Boyle’s Law: Volume of a gas varies with the pressure exerted on it.
