  1. EOC Review Famous Scientists

  2. Archimedes • He discovered pi. • He developed levers and pulleys. • Formula– surface and volume of a sphere.

  3. Archimedes Water screw • The waterscrew brought water to the surface, enabling farmers to irrigate their crops.

  4. Eratosthenes • Greek mathematician • Measured the circumference of the earth. • Did a good deal of work with prime numbers.

  5. Pythagoras • A(2) + B(2) = C(2) • Pythagorean theorem

  6. The Islamic Golden Age • “The Father of Algebra,” Muhammad ibn Musa al Khwarizmiwas a scholar in the House of Wisdom. • He was a mathematician, astronomer and geographer.

  7. Arab scholars also improved the workings of the astrolabe. • Astrolabes are used to determine one’s location based on the position of the planets and stars. • This made it possible for men like Columbus to sail to the Americas. A 16th Century Astrolabe above

  8. Nicolaus Copernicus • He was the 1st to claim that the Earth was not the center of the universe. • That planets, including the Earth, revolved around the sun. • This is the Heliocentric view of the cosmos.

  9. Galileo Galileo • With the use of his telescope, Galileo will prove that Copernicus was right. • He published TheStarry Messenger in 1610, radically changing our awareness of the cosmos. An original Galilean telescope.

  10. Galileo Galileo • In the Dialogue, Galileo put forth the Heliocentric view of the cosmos. The church brought Galileo before an inquisition and forced him to recant.

  11. Robert Boyle Robert Boyle • Boyle pioneered work on the properties of gases that led to Boyle’slaw : volume of a gas varies with the pressure exerted on it.

  12. Sir Isaac Newton Sir Isaac Newton • He is best known for his laws of: • Optics • Gravity • Motion • Inertia • Math - Calculus

  13. James Watt James Watt • Watt – Improved the steam engine. • Steam powered mechanical engines, allowing them to be placedanywhere. • Steam engines led to factories – radically changing the world from a rural one to an urban one.

  14. Charles Darwin Charles Darwin • 1859 - Published the Origin of the Species • Theories of: natural selection and survival of the fittest.

  15. Charles Darwin Charles Darwin • Theory of evolution – Belief that all forms of life, including humans, evolved from earlier living forms that had existed millions of years ago. • Directly contradicted creation theories.

  16. Marie Curie Marie Curie • Greatest female scientist of all time. • 2 time Nobel Prize winner in 1903 and 1911 for the following discoveries: • Discovered elements of radium and polonium.

  17. Marie Curie Marie Curie • She was the first woman to win a Nobel Prize in Physics and later in Chemistry. • She isolated properties of radium for use in x-ray machines.

  18. Louis Pasteur Louis Pasteur • 1870’s - Developed the process of pasteurization. • Discovered organisms he called bacteria. • Pasteurization is the use of heat to kill germs in liquids like milk.

  19. Albert Einstein Albert Einstein • Theory of relativity – argued that space and time are not constant. • New ideas on space, time, energy and matter. E=mc(2)

  20. Thomas Edison Thomas Edison • “The Wizard of Menlo Park.” • Inventor of the Light-bulb. • Invented the phonograph and movie projector.

  21. Impact – Gutenberg’s Printing Press • Information could be printed faster and cheaper than before. • Information spread quickly, powering the Renaissance, Protestant Reformation (Luther), and the Age of Discovery (Maps for Columbus).

  22. Impact – Edison’s Light-Bulb • It lengthened the work day. Businesses could now run 24 hours a day. • This made the Industrial Revolution in the USA even more productive than before.

  23. Impact – Watt’s Steam Engine • It powered the Industrial Revolution. • Factories could now be built almost anywhere. • Machines could produce more goods – faster and cheaper.
