    Albert Einstein

    • Albert is most famously known for his formula E=mc^2. This equation was used to show that energy and mass are the same thing. (1905)
    • Born 3/14/1879 and passed away on 4/18/1955
    • His discovers were important because we use his equation in science when were dealing with mass and energy.
  • Period: to

    • Mathematician
    • Born 276 BC. Died 194 BC
    • Most famously known for measuring the size of the Earth.
    • His discovery's help us today in many math classes, and in some schools he is very well known.
