    On 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.

    On This Day - Mar 22 : Robert Millikan was born

    Famous for using oil droplets to measure the charge of an electron for the first time, Millikan went on to experimentally investigate the photoelectric effect corroborating Einstein’s theories. Millikan was awarded the Nobel Prize in Physics in 1923 for this work.

    On This Day - Mar 20 : Volta revealed the battery

    He wrote to the president of the Royal Society detailing his invention, which was initially called the ‘electric pile’. The battery consisted of alternating copper (Cu) and zinc (Zn) discs, connected by pieces of leather or card soaked in salt water.

    On This Day – Jul 11 : Samuel Goudsmit was born

    He introduced the concept of electron spin along with George Eugene Uhlenbeck in 1925. This phenomenon explains many aspects of atomic behaviour that cannot be explained by classical physics.

    On This Day – Sep 02 : Friedrich Ostwald was born

    He was one of the founders of classical physical chemistry. In particular, Ostwald was a pioneer of electrochemistry and chemical dynamics. He won the Nobel Prize for Chemistry in 1909 for his work on catalysis, chemical equilibrium, and reaction velocities.

    On This Day - May 01 : AC motor patented

    Not only was this the first alternating current (AC) motor, but it also heralded a new system of power transmission, which is the basis for the mains power we use today. The Serbian-American physicist, engineer and inventor is recognised as one of the pioneers of electric power.

    On 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.

    On 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.

    On 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.
