-
He was the first to propose an atomic universe. Democritus reportedly wrote over 70 treatises, only a few hundred fragments have survived.
-
He was founder of the Platonist school of thought, and the Academy, the first institution of higher learning in the Western world.
-
He made significant contributions to astronomy simply by observing how nature behaved and always being inquisitive about the mysteries of the world.
-
they discovered phosphorus. Johann Georg Rapp was a famous alchemist.
-
He discovered that the volume of a gas decreases with increasing pressure. He is known by many as the Father Of Modern Chemistry.
-
Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. He also named oxygen and hydrogen.
-
He did experiments on gases that led him to discover that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space.
-
He is best known for his discovery of the periodic law, and for his formulation of the periodic table of elements.
-
He announced his discovery that atoms were made up of smaller components. And discovered the electron and then went on to propose a model for the structure of the atom. He invented the plum pudding model.
-
He came up with the concept that light is made up of particles called photons. Most scientists of his day didn't agree, but later experiments showed this to be the case.
-
He was a physicist who discovered the elementary charge of an electron using the oil-drop experiment. He charged droplets of oil between two electrodes and balanced the gravitational force with the upward forces
-
He postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay.
-
Neils Bohr discovered that electrons travel in separate orbits around the nucleus, and that the number of electrons in the outer orbit determines the properties of an element.
-
He used self-built equipment to prove that every element’s identity is uniquely determined by the number of protons it has. His discovery revealed the true basis of the periodic table
-
She championed the use of portable X-ray machines in the field for WW1. These medical vehicles earned the nickname "Little Curies."
-
He discovered a way to formulate quantum mechanics in terms of matrices. He also was a main contributor to the German atomic program during World War II, in direct competition with the Manhattan Project.
