ResourceOn This Day - Apr 23 : Max Planck was born
Max Planck was the founder of quantum theory. He came up with the equation E = hν, which related the frequency of light emitted by a body to its energy.
-
ResourceOn This Day - May 24 : Daniel Fahrenheit was born
He invented the alcohol thermometer (1709) and mercury thermometer (1714). He also developed the Fahrenheit temperature scale by reference to three fixed points of temperature, where a mixture of ice, water and ammonium chloride was taken as 0 °F.

ResourceOn This Day - Jun 25 : Walther Nernst was born
He was a pioneer in physical chemistry. Nernst is best known for his theories relating to the calculation of chemical affinity, which is the ability of chemicals to form compounds with one another. He won the 1920 Nobel Prize in Chemistry.

ResourceOn This Day – Sep 28 : Metre was defined
One metre was defined as the distance between two lines on a standard bar of an alloy of platinum (Pt) with 10% iridium (Ir), measured at the melting point of ice. The original international prototype of the metre is still kept at the BIPM, Bureau International des Poids et Mesures, in Sèvres, France.

ResourceOn This Day - Jan 17 : Friedrich Kohlrausch died
His research focussed on the thermal, electrical and magnetic properties of electrolytes. He is recognised as one of the most important experimental physicists, with his early work contributing to the absolute system of electrical and magnetic measuring units.
-
ResourceOn This Day - Feb 19 : Svante Arrhenius was born
He is one of the founders of physical chemistry and perhaps most famous for proposing the Arrhenius equation, which describes the rate of a chemical reaction.

ResourceOn This Day - Jan 31 : Irving Langmuir was born
He was awarded the Nobel Prize in Chemistry in 1932 for his work on monolayers and surface absorption. He was the first non-academic chemist to be awarded the prize.
