Newsletter for Saturday 14 June


TODAY IN SCIENCE HISTORY
NEWSLETTER - 14 JUNE

Feature for Today
On 14 Jun 1736, Charles-Augustin de Coulomb was born, whose contributions to the measurement of electrical charge were recognized by the naming of its unit after him.

A biography of Charles-Augustin de Coulomb in Pioneers of Electricity (1890) is very informative on the diverse interests of this remarkable scientist. Among the interesting facts you probably did not know about him was that he was sent to the prison of the Abbaye over a report on a canal!

Of course, as you would expect, his introduction of measurement to the study of electrical charge is a large part of this biography of this remarkable person - another scientist about whom you can learn some background you perhaps would never have otherwise known he studied (for example, about the sap of poplar trees!).

Book of the Day
On 14 Jun 1946, A Scottish engineer died who was the first man to televise outline pictures of objects (1924) followed the next year by recognizable human faces. You may be able to name him in the quiz below.Today's Science Store pick is: Television and Me, an autobiography by that pioneering TV engineer. He writes with blunt candour and caustic wit about the wild escapades of his early business career and later troubled relationship with Lord Reith and the fledgling BBC. With much new material, including a recently discovered final chapter by his wife, this heavily illustrated edition of his autobiography gives us a very human portrait of one of the creators of the modern world. Price New $19.95. Also available Used from $4.74 (as of time of writing).

Yesterday's pick: The Man Who Changed Everything, by Basil Mahon.

Quotations for Today
"Our brains seem to be organised to make random comparisons of the contents of our memories. Daydreaming allows the process to go into free fall. Suddenly, there is a new idea, born with intense excitement. We cannot organise this process but we can distort or even defeat it." (Commenting that creativity is not a method that can be learnt and taught.)
- Sir James Black, Scottish pharmacologist (born 14 Jun 1924) Quotes Icon
"A single kind of red cell is supposed to have an enormous number of different substances on it, and in the same way there are substances in the serum to react with many different animal cells. In addition, the substances which match each kind of cell are different in each kind of serum. The number of hypothetical different substances postulated makes this conception so uneconomical that the question must be asked whether it is the only one possible. ... We ourselves hold that another, simpler, explanation is possible."
- Karl Landsteiner, Austrian-American physician, immunologist and pathologist (born 14 Jun 1868) Quotes Icon
"Moreover, the sciences are monuments devoted to the public good; each citizen owes to them a tribute proportional to his talents. While the great men, carried to the summit of the edifice, draw and put up the higher floors, the ordinary artists scattered in the lower floors, or hidden in the obscurity of the foundations, must only seek to improve what cleverer hands have created."
- Charles-Augustin de Coulomb, French physicist (born 14 Jun 1736) Quotes Icon

Births
On 14 Jun 1864, the German psychiatrist, who recognized a disease named after him, was born. In Nov 1901, a 51-year old female patient with signs of dementia had been admitted to the Frankfurt hospital where this doctor was working. At a meeting German psychiatrists in Nov 1906, he reported on this patient. The title of his lecture was �ber eiene eigenartige Erkrankung der Hirnrinde (On a peculiar disorder of the cerebral cortex): Presenile dementia is a progressive, degenerative disorder that affects the brain. The first symptoms are loss of memory, inability to think and understand and gradual behaviour changes. Death follows in from 8 to 20 years. Presenile dementia is now known by the name of this psychiatrist.

Charles-Augustin de Coulomb was born 14 Jun 1736, the French physicist who is best known for the formulation of Coulomb's law. In 1777, he invented a torsion balance which he subsequently modified for electrical measurements. He also did research on friction of machinery, on windmills, and on the elasticity of metal and silk fibres.
What is Coulomb's law?
Deaths
A Scottish engineer (1888-1946) was the first man to televise outline pictures of objects (1924) followed the next year by recognizable human faces. By 1926, he was able to demonstrate TV for moving objects at the Royal Institution, London. He demonstrated colour television in 1928. The British Broadcasting Corporation (BBC) formed in 1936 considered his system, but it was the competing system of Marconi Electric and Musical Industries that the BBC adopted in Feb 1937. He continued experimenting, and was reported to have completed his researches on stereoscopic television in 1946.
