Jacobus Cornelius Kapteyn and the Rotation of the Milky Way

Harald Sack
On June 18, 1922, Dutch astronomer Jacobus Cornelius Kapteyn passed away. Kapteyn carried out extensive studies of the Milky Way and was the discoverer of evidence for galactic rotation. He used photography and statistical methods in determining the motions and spatial distribution of stars, the first major step after the works of William and John Herschel.[6,7] Jacobus C. Kapteyn – Early Year Jacobus Cornelius Kapteyn was born on 19 January 1851 in…

Alexis Claude Clairaut and the True Figure of the Earth

Alexis Claude Clairaut and the True Figure of the Earth

Harald Sack
On May 13, 1713, French mathematician, astronomer, and geophysicist Alexis Claude Clairaut was born. Clairaut was one of the key figures in the expedition to Lapland that helped to confirm Newton’s theory for the figure of the Earth.[3] In that context, Clairaut worked out a mathematical result now known as “Clairaut’s theorem“. He also tackled the gravitational three-body problem, being the first to obtain a satisfactory result for the apsidal precession of…

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 Clinical Teaching of Herman Boerhaave

The Clinical Teaching of Herman Boerhaave

Tabea Tietz
On December 31, 1668, Dutch botanist, chemist, Christian humanist and physician Herman Boerhaave was born. Boerhaave is regarded as the founder of clinical teaching and of the modern academic hospital and is sometimes referred to as “the father of physiology”. He is best known for demonstrating the relation of symptoms to lesions and, in addition, he was the first to isolate the chemical urea from urine. He was the first physician that…

William Cheselden and the Profession of Surgery

William Cheselden and the Profession of Surgery

Tabea Tietz
On October 19, 1688, English surgeon and teacher of anatomy and surgery William Cheselden was born. Cheselden was influential in establishing surgery as a scientific medical profession. Via the medical missionary Benjamin Hobson, his work also helped revolutionize medical practices in China and Japan in the 19th century. Cheselden published Anatomy of the Human Body, (1713) written in English instead of the Latin, which remained in print as a text for anatomy students…

Pierre Duhem and the Role of Theory in Science

Pierre Duhem and the Role of Theory in Science

Harald Sack
On June 10, 1861, French physicist, mathematician, historian and philosopher of science Pierre Duhem was born. He is best known for his work on chemical thermodynamics, for his philosophical writings on the indeterminacy of experimental criteria, and for his historical research into the science of the European Middle Ages. As a scientist, Duhem also contributed to hydrodynamics and to the theory of elasticity. “A physical theory … is a system of mathematical…

James Clerk Maxwell and the very first Colour Photograph

James Clerk Maxwell and the very first Colour Photograph

Harald Sack
On May 17, 1861, Scottish physicist Sir James Clerk Maxwell presented the very first colour photograph at the Royal Institution. The photograph showed a tartan ribbon and was made by Thomas Sutton according to the three-colour method proposed by Maxwell already in 1855. „Die Menschen empfinden im Allgemeinen eine große Freude an der Farbe. Das Auge bedarf ihrer, wie es des Lichtes bedarf.“ (“People generally take great pleasure in color. The eye…

Edmond Halley besides the Eponymous Comet

Edmond Halley besides the Eponymous Comet

Harald Sack
On November 8, 1656, English astronomer, geophysicist, mathematician, meteorologist, and physicist Sir Edmond Halley was born. Of course everybody has heard of Halley’s comet. We too already had an article on that topic [1]. But, Edmond Halley did much more than calculating the orbit of the eponymous comet. He compiled a catalogue of the stars of the Southern hemisphere, he also improved the sextant, and made observations about the ocean and the…

Maurice René Fréchet and the Theory of Abstract Spaces

Maurice René Fréchet and the Theory of Abstract Spaces

Harald Sack
On September 2, 1878, French mathematician Maurice René Fréchet was born. Fréchet is known chiefly for his contribution to real analysis. He is credited with being the founder of the theory of abstract spaces, which generalized the traditional mathematical definition of space as a locus for the comparison of figures; in Fréchet‘s terms, space is defined as a set of points and the set of relations. He also made several important contributions…

Archimedes lifted the world off its Hinges

Archimedes lifted the world off its Hinges

Harald Sack
Without knowing his exact date of birth or even death, we focus today on one of the leading scientists in classical antiquity: the ancient Greek mathematician, physicist, engineer, inventor, and astronomer Archimedes of Syracuse, who was born around 287 BC and died at about 212 BC. Only a few details of his life are known, but he is considered the greatest mathematician of antiquity and one of the greatest of all time. Archimedes…
