  3. 3. <ul><li>Returned home started to work for Hieron II </li></ul><ul><li>Discovered volume when King Hieron II wanted to know if his crown was pure gold. Archimedes discovered solution while taking a bath from how much water overflowed the tub. </li></ul><ul><li>During second Punic war in 214BC, King Hieron II asked Archimedes to make inventions of war-machines for defense against Roman general Marcellus(second Punic War laid siege to Syracuse) </li></ul><ul><li>Archimedes was unsure about helping because he didn’t want to hurt anyone but in the end agreed to the job. </li></ul>Back in Syracuse Hieron II, 7 October 2010 www. chestofbooks .com
  4. 4. <ul><li>Archimedes claw (utilizing pulley system) – a type of crane with a hook that was able to life attacking ships partly out of the water. </li></ul><ul><li>Burning mirrors- Archimedes figured out you can use mirrors to concentrate the sun’s rays onto a small area and cause exposed areas to start to burn. Used to ketch attacking ships on fire. </li></ul><ul><li>Compound Pulley- Which is a rope, belt, or cable that runs over a wheel in a groove. They are used to change the direction of an applied force or transmit rotational motion. </li></ul><ul><li>Made improvements to Leonardo Da Vinci’s steam cannon, Zhang Heng’s Water clock, and the ancient catapult system </li></ul><ul><li>Odometer- indicates distance traveled </li></ul>Inventions for the Second Punic War Archimedes claw, 7 October 2010 www.nyu.edu
  5. 5. Mathematics Discoveries <ul><li>One of the first people to relate mechanics and mathematics </li></ul><ul><li>Discovered Powers </li></ul><ul><li>Determined exact value of pi between 3 10/71 and 3 1/7 </li></ul><ul><li>Archimedes made many contributions to geometry through his work on the area of plane figures and areas and volumes of curved surfaces. </li></ul><ul><li>His methods started idea for calculus </li></ul>Pi, 7 October 2010 www.archive. perfectduluthday .com
  6. 6. Science Discoveries <ul><li>Figured out every object has a center of gravity </li></ul><ul><li>Discovered density and volume </li></ul><ul><li>Created new theorems for law of buoyancy </li></ul><ul><li>Archimedes Principle- an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object </li></ul><ul><li>Made first planetarium </li></ul>Archimedes Planetarium, 7 October 2010 www. cs . drexel . edu
  7. 7. Survived Works <ul><li>On the Equilibrium of Planes, Part I </li></ul><ul><li>The Quadrature of the Parabola </li></ul><ul><li>On the Equilibrium of Planes, Part II </li></ul><ul><li>On Spirals </li></ul><ul><li>On the Sphere and the Cylinder, Parts I and II </li></ul><ul><li>On Floating Bodies </li></ul><ul><li>On Conoids and Spheroids </li></ul><ul><li>The Sand-Reckoner </li></ul><ul><li>The Method of Mechanical Theorems </li></ul><ul><li>Measurement of a Circle </li></ul>Measurement of a circle, 7 October 2010 www. historyforkids .org
  8. 8. Death <ul><li>A Roman Soldier killed Archimedes after the siege of Syracuse because Archimedes would not follow the Soldier’s orders. When Marcellus, Roman commander, herd about Archimedes death, he ordered a monument be put up in Archimedes honor. </li></ul>Death of Archimedes, 7 October 2010 www. mlahanas .de
