  • Born on January 8,1942 in Oxford, England.

  • Physics was not his primary choices in college.

  • Has ALS- Amyotrophic Lateral Sclerosis or commonly known as Lou Gehrig's disease.

Stephen Hawking

  • Went to Cambridge and got Ph.D in cosmology

  • Cosmology-the study of the universe as a whole

  • Has 12 honorary


Stephen hawking3
Stephen Hawking

  • Developed theories for black holes saying that they emit radiation which can be detected by special instrumentation.

  • First theorized that black holes can never decrease in size nor can they split in two to create two black holes.

Stephen hawking4
Stephen Hawking

  • He realized that particles, in fact, do leak from black holes.

  • As matter compresses, it emits radiation into a surrounding curved sphere of space called an “event horizon”.

  • As the black hole shrinks into its own gravitational pull, the temperature rises and so does the rate at which particles are emitted into the event horizon. This process is now called Hawking’s Radiation.

  • Hawking’s Radiation is the process through which a black hole turns in on itself, essentially turning itself inside out, and disintegrating.

Nicolaus Copernicus was born on the 19th of February 1473. He passed away at the age of 70 on the 24th of May 1543.

Nicolaus was born in the city of Thorn in Royal Prussia, part of the Kingdom of Poland.

His field of expertise was in mathematics, astronomy, canon laws, medicine, and economics.

He studied at the University of Cracow from 1491 to 1494.

He spoke 5 different languages which include: Latin, German, Polish, Greek, and Italian.

Nicolaus came up with a theory that the Earth isn’t the center of the universe. He believed that the center of the Earth is the sun. The planets go around the sun, instead of the universe circling the earth.

He proposed a heliocentric and suggested that Earth was a planet, that it rotated, and that Earth and the other planets revolved around the sun.

His real name was Nikals Kopenik and it was Latinized to Nicolaus Copernicus. He came from a middle class background. When Nicolaus Copernicus was 10 his father died and he was raised by his uncle. His uncle gave him a good education.

Biography continued1


Nicolaus Copernicus was a true Renaissance man. He also was a lawyer, tax collector, a doctor, military governor, judge, vicar-general of canon law and a Polish astronomer.

His book De Revolutions “On the Revolutions of the Heavenly Spheres” was his most famous piece of work.

Copernicus book was published in March 1543 at Nuremberg

Nicolaus Copernicus's knowledge was spread to others and he also set the scene for major advances in science. Copernicus also marked the beginning of a scientific revolution and astronomy.

Copernicus first studied astronomy and astrology at the University of Cracow (1491-94).

Copernicus studied medicine at the University of Padua (1501-3)

And then moved on to the University of Ferrara where he obtained a doctorate in Canon Law (1503).

After he published his book two months later, Nicolaus Copernicus died from a stroke induced coma in 1543.

Important accomplishments discoveries
Important Accomplishments/ Discoveries

  • Newton invented Newton’s Laws of Motion:

  • Every object remains in rest unless acted upon by an external, unbalanced force

  • Rate of change of momentum of a body= to the force applied to that body & direction of the force

  • Every action has an equal & opposite reaction

  • He formed a new formula to calculate Pi

  • Newton led the discovery that a prism can decompose white light into a spectrum of colors

  • Universal Gravitation states every point mass in the universe attracts another with a direct force

  • Probably was born around 85?-165?

  • Born in Egypt

  • He created horoscopes

Claudius ptolemy2
Claudius Ptolemy

  • Made his most original contribution by presenting details for the motions of each of the planets.

  • The earliest and most important of Ptolemy’s work that has survived is the Almagest.

Claudius ptolemy3
Claudius Ptolemy

  • He wrote 13 books.

  • Ptolemy first of all justifies his description of the universe based on the earth-centred system described by Aristotle.

Claudius ptolemy4

  • In books 4 through 6, Ptolemy gives his theory of the moon.

  • The next 2 books deal with fixed stars.
