Sir Joseph William Bazalgette and the Great Stink of 1858

Sir Joseph William Bazalgette and the Great Stink of 1858

Tabea Tietz
On March 28, 1819, British civil engineer Joseph William Bazalgette was born. As chief engineer of London‘s Metropolitan Board of Works Bazalgette‘s major achievement was the creation in response to the Great Stink of 1858 of a sewer network for central London which was instrumental in relieving the city from cholera epidemics, while beginning the cleansing of the River Thames. From Railway Projects to London’s Sewers Joseph William Bazalgette was mainly educated at home…

James Prescott Joule and the True Nature of Heat

James Prescott Joule and the True Nature of Heat

Tabea Tietz
On December 24, 1818, English physicist and brewer, James Prescott Joule was born. Joule studied the nature of heat, and discovered its relationship to mechanical work. This led to the law of conservation of energy, which led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after James Joule. “My object has been, first to discover correct principles and then to suggest their practical…

Lord Kelvin and the Analysis of Thermodynamics

Lord Kelvin and the Analysis of Thermodynamics

Harald Sack
On December 17, 1907, Irish physicist William Thomson, 1st Baron Kelvin of Largs, passed away. Thomson did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics. Absolute temperatures are stated in units of kelvin in his honour. He was ennobled in 1892 in recognition of his achievements in thermodynamics. Go, wondrous creature! mount where Science guides; Go measure earth, weigh air, and state…

Scientist and Politician François Arago

Tabea Tietz
On February 26, 1786, French mathematician, physicist, and astronomer François Arago was born. Arago discovered the principle of the production of magnetism by rotation of a nonmagnetic conductor. He also devised an experiment that proved the wave theory of light and engaged with others in research that led to the discovery of the laws of light polarization. “Connaître, découvrir, communiquer—telle est, au fond, notre honorable destinée. To get to know, to discover, to…

James Dewar and the Liquefaction of Gases

Harald Sack
On September 1842, Scottish chemist and physicist Sir James Dewar was born. He is probably best-known today for his invention of the Dewar flask, which he used in conjunction with extensive research into the liquefaction of gases. James Dewar Background James Dewar was born in Kincardine, Fife, Scotland, in 1842, the youngest of six boys. He lost his parents at the age of 15. He was educated at Dollar Academy and the…

John Tyndall and the Physics of Air

John Tyndall and the Physics of Air

Harald Sack
On August 2, 1820, British physicist John Tyndall was born. His initial scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air. As the most prominent example, he was able to demonstrate why the sky is blue. “Every occurrence in Nature is preceded by other occurrences which are its causes, and succeeded by others which are…

James Clerk Maxwell and the Electromagnetic Fields

James Clerk Maxwell and the Electromagnetic Fields

Tabea Tietz
On June 13, 1831, Scottish physicist James Clerk Maxwell was born. His most prominent achievement was formulating a set of equations that united previously unrelated observations, experiments, and equations of electricity, magnetism, and optics into a consistent theory. According to his theory he has demonstrated that electricity, magnetism and light are all manifestations of the same phenomenon, namely the electromagnetic field. This has been called the “second great unification in physics”, after the…

The Royal Society of London for Improving Natural Knowledge

Tabea Tietz
On November 28, 1660, at Gresham College, London, UK, 12 men, including Christopher Wren, Robert Boyle, John Wilkins, and Sir Robert Moray decide to found what is later known as the Royal Society of London for Improving Natural Knowledge, a learned society for science, and possibly the oldest such society still in existence. “Nullius in Verba.” (On no man’s word.) – Motto of the Royal Society It all started with Roger Bacon…

Humphry Davy and the Wonders of Electrolysis

Humphry Davy and the Wonders of Electrolysis

Tabea Tietz
On November 19, 1807, British chemist and inventor Humphry Davy reported to the Royal Society about the isolation of potassium and sodium from different salts by electrolysis. Davy was one of the pioneers in the field of electrolysis using the newly invented voltaic pile to split up common compounds and thus prepare many new elements.[6] “Nothing is so fatal to the progress of the human mind as to suppose that our views…

A Life of Discoveries – the great Michael Faraday

Tabea Tietz
On September 22, 1791, the famous chemist and physicist Michael Faraday  was born. He is responsible for the discovery of the electromagnetic induction, the laws of electrolysis and best known for his inventions, which laid the foundations to the electrical industry. But, to understand the person and the scientist Michael Faraday, we have to look a little bit into his background and his development. “I was at first almost frightened when I…
