International Day of Light

Mittwoch/Wednesday, 16.05.2018, Switzerland

Logo

The International Day of Light is a global initiative that provides an annual focal point for the continued appreciation of light.

The chosen date May 16th is the anniversary of the first laser emission by Theodore Harold Maiman (July 11, 1927 – May 5, 2007). He was an American engineer and physicist credited with the building of the first working laser.

Maser was invented by Charles Hard Townes  (July 28, 1915 – January 27, 2015). This American physicist shared the Nobel Prize in Physics during 1964 with Nikolay Basov and Alexander Prokhorov.

Max Born (11 December 1882 – 5 January 1970) was a German physicist and mathematician who was instrumental in the development of quantum mechanics.  Born won the 1954 Nobel Prize in Physics for his fundamental research in quantum mechanics, especially in the statistical interpretation of the wave function.

Jost Bürgi (28 February 1552 – 31 January 1632) was a Swiss clockmaker, a maker of astronomical instruments and a mathematician.
An introduction to some of Buergi's methods survives in a copy by Kepler; it discusses the basics of Algebra, and of decimal fractions. Some authors consider Bürgi as one of the inventors of logarithms. His legacy also includes the engineering achievement contained in his innovative mechanical astronomical models.

Jean-Baptiste Joseph Fourier (21 March 1768 – 16 May 1830) was a French mathematician and physicist and best known for initiating the investigation of Fourier series and their applications to problems of heat transfer and vibrations. The Fourier transform and Fourier's law are also named in his honour. Fourier is also generally credited with the discovery of the greenhouse effect.
