François Lenormant and the Akkadian Language

Harald Sack
On January 17, 1837, French assyriologist and archaeologist François Lenormant was born. Lenormant recognized, from cuneiform inscriptions, a language now known as Akkadian that proved valuable to the understanding of Mesopotamian civilization 3,000 years before the Christian era. François Lenormant – Youth and Education François Lenormant was born in Paris, France, to his father Charles Lenormant, who, distinguished as an archaeologist, numismatist and Egyptologist, was anxious that his son should follow in…

Stephen Hawking and the Hairy Black Holes

Stephen Hawking and the Hairy Black Holes

Harald Sack
When I read the news that Stephen Hawking passed away, I was rather sad. I grew up with a fascination for astronomy and cosmology. Trying to understand the fabrics and working of the universe, I devoured his popular books and articles and I am rather thankful. Amongst others it was foremost this unique physicist, who planted the seed for my decision to become a scientist myself. However, I abandoned physics after high…

The Short Life of Srinivasa Ramanujan

The Short Life of Srinivasa Ramanujan

Harald Sack
On December 22, 1887, Indian mathematician and autodidact Srinivasa Ramanujan was born. Though he had almost no formal training in pure mathematics, he made major contributions to mathematical analysis, number theory, infinite series, and continued fractions. Supported by English mathematician G. H. Hardy from Cambridge, Ramanujan independently compiled nearly 3,900 results during his short life, which all have been proven correct. “Sir, an equation has no meaning for me unless it expresses…

Charles Coulson and the Molecular Orbital Theory

Harald Sack
On December 13, 1910, British applied mathematician and theoretical chemist Charles Coulson was born. Coulson was as a pioneer of the application of the quantum theory of valency to problems of molecular structure, dynamics and reactivity. He is known for the application of molecular orbital theory to chemical bonding, the electronic structures of molecules and the concept of partial valency, and developed many mathematical techniques for solving chemical and physical problems.

Robert Noyce – the “Mayor of Silicon Valley”

Tabea Tietz
On December 12, 1926, American engineer and inventor Robert Noyce was born. Nicknamed “the Mayor of Silicon Valley,” Noyce co-founded Fairchild Semiconductor in 1957 and Intel Corporation in 1968. He is credited along with Jack Kilby with the realization of the first integrated circuit or microchip that fueled the personal computer revolution. “Innovation is everything. When you’re on the forefront, you can see what the next innovation needs to be. When you’re behind, you…

Heinrich Barkhausen and the Barkhausen Effect

Tabea Tietz
On December 2, 1881, German physicist Heinrich Barkhausen was born. Barkhausen discovered the Barkhausen effect (1919), a principle concerning changes in the magnetic properties of metal. With K. Kurz, he invented the Barkhausen-Kurz oscillator, the first vacuum tube electronic oscillator to use electron transit-time effects. Heinrich Barkhausen – Early Years Heinrich Barkhausen came from a respected Bremen middle-class family. He showed interest in technology and natural sciences in his early youth, whereupon his…

Yuri Knorozov and the Decipherment of the Mayan Language

Harald Sack
On November 19, 1922, Soviet linguist epigrapher and ethnographer Yuri Knorozov was born. Knorozov is particularly renowned for the pivotal role his research played in the decipherment of the Maya script, the writing system used by the pre-Columbian Maya civilization of Mesoamerica. “There are no indecipherable writings, any writing system produced by man can be read by man.” — Yuri Knozorov, Epigraphic Atlas of Petén Phase 1 Youth and Education Yuri Knorozov was born…
