Proved that the relative quantities of any given pure chemical compound’s constituent elements remain invariant, regardless of the compound’s source. This is known as Proust’s law.
-
He produced electromagnetic waves in the laboratory and measured their length and velocity.
-
Discovered the electron.
-
Originated quantum theory.
-
Won Nobel Peace Prize in Physics for discovery of radium and polonium in their investigation of radioactivity.
-
Won Nobel Peace Prize in Physics.
-
Won Nobel Peace Prize in Chemistry.
-
Reported that alpha particles from a radioactive source were occasionally deflected more than 90° when they hit a thin metal foil. This observation helped Rutherford develop the nuclear model of the atom.
-
Discovered that the atom consists of a heavy positively charged nucleus with substantially lighter negatively charged electrons circling around it at considerable distance.
-
Einstein completed his General Theory of Relativity.
-
Won Nobel Peace Prize in Physics.
-
Won Nobel Peace Prize in Physics.
-
Won the Nobel Peace Prize
-
The so-called Compton effect is caused by the transfer of energy from a photon to an electron.
-
He worked with Ernest Rutherford in the Cavendish Laboratory, Cambridge, where they studied the transmutation of elements by bombarding them with alpha particles and investigated the nature of the atomic nucleus, identifying the proton, the nucleus of the hydrogen atom, as a constituent of the nuclei of other atoms.
-
Broglie developed his revolutionary theory of electron waves.
-
Discovered a way to formulate quantum mechanics in terms of matrices.
-
Synthesized new radioactive elements.
-
He used his counter to confirm the existence of light quantum, or packets of energy.
-
Discovered that in an atom no two electrons can occupy the same quantum state simultaneously.
-
Nobel Prize for Physics for his discovery and explanation of the change in the wavelength of X rays when they collide with electrons in metals.
-
Relativistic quantum theory of the electron.
-
Won Nobel Peace Prize in Physics.
-
In 1932 Chadwick observed that beryllium, when exposed to bombardment by alpha particles, released an unknown radiation that in turn ejected protons from the nuclei of various substances. Chadwick interpreted this radiation as being composed of particles of mass approximately equal to that of the proton, but without electrical charge—neutrons.

-
Won the Nobel Peace Prize for Physics his discovery of the positron, or positive electron, the first known particle of antimatter. In 1936 Anderson discovered the mu-meson, or muon, a subatomic particle 207 times heavier than the electron.
