1905 – photoelectric effect

Maxwell‘s equations showed that light, electricity and magnetism all had similar wave characteristics and suggested that light was a variation of the electro-magnetic wave form. If this was true, light and other electro-magnetic waves impacting metal would cause a flow of electric current in the metal. At the time, scientists were using electrified glass tubes […]

1900 – Pauli – bio

Wolfgang Pauli was born in Vienna, Austria in 1900 and was a physicist known as one of the creators of quantum mechanics. He particularly become known for the “Pauli Exclusion Principle” which states that no two electrons can be in the same quantum state at the same time. PRECURSOR: 1831 – Maxwell 1838 – Mach […]

1858 – Planck – bio

Max Planck was born in 1858 in Kiel, Germany and was the physicist responsible for creating the beginnings of quantum theory. Planck was working on a description of electromagnetic radiation when he discovered that energy is only radiated in discrete bundles, or quanta. A constant derived from the equation he produced is now known as […]
