-
Albert's theory was of relativity. It was determined by the laws of physics. Also showed that the light within a vacuum is the same no matter the speed at which it travels.
-
His discovred the atomic structure. in which the electrons were embedded in a positively charged atom like plums in a pu dding.
-
He discovered the periodic table's true basics.
-
Neils Bohr introduced his model in 1913, that travel in a circular motion just like the solar system. The atoms travel around the nueclus
-
His atomic model was apart of modern physics that showed protons and neutrons. On the outside was the electrons orbiting the neucleus.
