Marie Curie was born in Poland as Maria Sklodowska, discovered radioactivity, and was the first person to win two Nobel Prizes. She discovered that the activity of uranium depended only on its quantity and that radiation came from within atoms. Albert Einstein postulated that light travels in individual photons in 1905, and published his special theory of relativity that same year and general theory of relativity in 1916. He is renowned for his contributions to early 20th century physics. Niels Bohr researched the structure of atoms, first postulating that electrons travel around the nucleus and predicted splitting of uranium atoms.

extraordinary Facts relating to the Vision
of Colors. This was the first paper ever
to discover color blindness.

7. Who was it?
 I came to know that the activity of
uranium depended only on the quantity of
uranium present and that radiation did
indeed come from the atom itself rather
than an interaction between molecules.

physicist, astronomer, engineer,
and weapon-designer
 I also invented one of the most
fundamental concepts of physics-
