Albert Einstein studied physics. He became famous for developing the theory of relativity and for conducting extensive research on the Brownian movement of molecules and the thermal properties of light. In 1921, he received the Nobel Prize in Physics.
Einstein's theory of relativity plays an essential role in modern physics. Einstein used the relativity principle to develop his theory of gravitation. He also studied Newtonian mechanics, statistical mechanics and the theory of radiation. In 1911, the German scientist became a professor of theoretical physics at Prague, but he also taught at Zurich and Berlin. He received honorary doctorate degrees in multiple fields, including medicine, science and philosophy and was one of the first faculty members of the Institute for Advanced Study.Learn More
Some examples of luminous objects are a burning candle, a light bulb, the sun and other stars, fluorescent materials and tube lights, among other things. Any object is considered luminous if it emits its own light, either through stored energy or energy supplied to the object, which contrasts with non-luminous objects such as the moon, wood, plastics and metals; these objects merely reflect light instead of providing their own.Full Answer >
Drift velocity describes the overall velocity of a particle that moves continually and changes its velocities and directions randomly. This velocity is best understood when imagining the free electron movement in a conductor.Full Answer >
Nuclear fission was discovered in 1938 by two German scientists, Otto Hahn and Fritz Strassmann. In 1939, it was explained theoretically by Lise Meitner and Otto Robert Frisch.Full Answer >
Matter made up of a single kind of atom is referred to as an element. Atoms are defined as the smallest particles of a given element that still express the element's chemical signatures.Full Answer >
