    My anology: Race cars driving in circles around a sphere.

  • Mari curie

    Mari curie
    Country: Poland
    Discovery: Marie curie studied the radiation of all compounds containig radioactive elements including uranium and thorium.
    -she also discovered that you can measure the exact strenghth of radiation from uranuim.
    -And that the amount of uranium or thorium in the compound predicts the intensity of radiation.
    - The ability to extract radiation does not depend on the way the atoms are arranged it has something to do with the atom iyself.
