  1. 1. E = mc2<br />A biography of the World’s Most Famous Equation <br /> By David Bodanis<br />
  2. 2. Brief Summary<br />Explores:<br />What does the equation mean:<br />What is Energy?<br />What is Mass?<br />What is the Speed of Light?<br />What are squaring and equality?<br />How Einstein discovered the equation<br />The formula in History<br />
  3. 3. Energy<br />Through vigorous experiments:<br />He found, as the amount of electricity went up the available magnetism went down<br />Discovered all types of energy are intertwined and can be measured<br />Lead to the Law of Conservation of Energy<br />Michael Faraday<br />
  4. 4. Mass<br />Perform precise experiments in most controlled conditions of his time with his wife<br />Eventually learn that substances can be burned, squeezed, shredded, but not destroyed. That the total mass throughout the universe remains the same.<br />Lead to the Law of Conservation of Mass<br />Antoine Lavoisier<br />
  5. 5. Speed Of Light<br />Comes from the Latin word celeritas translated as “swiftness” or “speed”<br />670,616,629 mph (constant used was 670 mil. mph)<br />
  6. 6. Squared and Equality<br />Robert Recorde<br />Du Châtlete<br />
  7. 7. Einstein<br /><ul><li> Thinks out of the Box:
  8. 8. It was THOUGHT that energy and mass were separate, but he connects them with the speed of light
  9. 9. Shuttle example
  10. 10. Discovers:
  11. 11. When someone watches an object recede away from them the object will be seen to undergo mass dilation, length changes, and time dilation.
  12. 12. Basically means that the mass of one object is a measure of its energy (and vice versa)
