89 years




Max Karl Ernst Ludwig Planck was a German physicist who is considered to be the inventor of quantum theory. In 1899, he discovered a new fundamental constant, which is named Planck's constant, and is, for example, used to calculate the energy of a photon. Also that year, he described his own set of units of measurement based on fundamental physical constants. One year later, he discovered the law of heat radiation, which is named Planck's law of black body radiation. This law became the basis of quantum theory, which emerged ten years later in cooperation with Albert Einstein and Niels Bohr....

Maxwell, Light is an Electromagnetic Wave
James Clerk Maxwell was a Scottish mathematical physicist. His most notable achievement was to formulate the classical theory of electromagnetic radiation, bringing together for the first time electricity, magnetism, and light as manifestations of th... 






Ludwig Boltzmann, Statistical Mechanics and Thermodynamics
Ludwig Eduard Boltzmann was an Austrian physicist famous for his founding contributions in the fields of statistical mechanics and statistical thermodynamics. He was one of the most important advocates for atomic theory at a time when that scientific... 






Albert Einstein, Relativity Theory  1905
Albert Einstein was a Germanborn theoretical physicist. Einstein developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). Einstein's work is also known for its influence on the philosophy of science... 






Otto Hahn, Father of Nuclear Chemistry
Otto Hahn was a German chemist and pioneer in the fields of radioactivity and radiochemistry. He was exclusively awarded the Nobel Prize in Chemistry in 1944 for the discovery and the radiochemical proof of nuclear fission. He is referred to as the f... 






Niels Bohr, Quantum Theory of Matter
Niels Henrik David Bohr was a Danish physicist who made fundamental contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. He was also part of the team of physicists working on... 






Erwin Schrödinger, Schrödinger's Cat
Erwin Schrödinger, sometimes written as Erwin Schrodinger or Erwin Schroedinger, was a Nobel Prizewinning Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he f... 






Pauli, Discovery Exclusion Principle
Wolfgang Ernst Pauli was an Austrian theoretical physicist and one of the pioneers of quantum physics. In 1945, after being nominated by Albert Einstein, he received the Nobel Prize in Physics for his "decisive contribution through his discovery of a... 






Paul Dirac, Prediction Existence of Antimatter
Paul Adrien Maurice Dirac was an English theoretical physicist who is regarded as one of the most significant physicists of the 20th century.
Dirac made fundamental contributions to the early development of both quantum mechanics and quantum elect...
