Aimé Argand
François-Pierre-Amédée Argand, known as Ami Argand (5 July 1750 – 14 or 24 October 1803) was a Genevan physicist and chemist. He invented the Argand lamp, a great improvement on the traditional oil lamp. Early life and education Francois-Pierre-Amédée Argand was born in Geneva, Republic of Geneva, the ninth of ten children. His father was a watchmaker, who intended for him to enter the clergy. However, he had an aptitude more for science, and became a pupil of the noted botanist and meteorologist Horace-Bénédict de Saussure. He published several scientific papers on meteorological subjects while in Paris in his late twenties. He took a teaching post in chemistry and developed some ideas for improving the distillation of wine into brandy, and, with his brother, successfully built a large distillery.

Alexander Mitchell (engineer)
Alexander Mitchell (13 April 1780 – 25 June 1868) was an Irish engineer who from 1802 was blind. He is known as the inventor of the screw-pile lighthouse. Early life Born in Dublin, his family moved to Belfast while he was a child, and he received his formal education at Belfast Royal Academy, where he excelled in mathematics. Career Originally working in brickmaking in Belfast, he invented machines used in that trade, before patenting the screw-pile in 1833, for which he would later gain some fame. The screw-pile was used for the erection of lighthouses and other structures on mudbanks and shifting sands, including bridges and piers. Mitchell's designs and methods were employed all over the world from Portland breakwater to Bombay bridges. Initially it was used for the construction of lighthouses on Maplin Sands in the Thames Estuary (the first light application, in 1838), the Wyre Light at Fleetwood in Lancashire (the first such beacon lit) completed, in 1839), and at ...

Pierre Jean Robiquet
Pierre Jean Robiquet (; 13 January 1780 – 29 April 1840) was a French chemist. He laid founding work in identifying amino acids, the fundamental building blocks of proteins. He did this through recognizing the first of them, asparagine, in 1806, while working as an assistant for Louis Nicolas Vauquelin. He likewise laid founding work in the industry's adoption of industrial dyes, with the identification of alizarin in 1826, and in the emergence of modern medications, through the identification of codeine in 1832, an opiate alkaloid substance of widespread use with analgesic and antidiarrheal properties. Robiquet was born in Rennes. He was at first a pharmacist in the French armies during the French Revolution years, and became a professor at the École de pharmacie in Paris, where he died. Notable scientific achievements were among other things his isolation and characterization of properties of asparagine (the first amino acid to be identified, from asparagus, achieved. In ...

Given annually, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray (scientist), Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". The medal is made of silver-gilt and awarded with a £25,000 prize. It is awarded to "senior scientists" irres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Chronometer
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), and the time at the current location found from observations of celestial bodies. When first developed in the 18th century, it was a major technical achievement, as accurate knowledge of the time over a long sea voyage was vital for effective navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man, John Harrison, spanning 31 years of persistent experimentation and testing that revolutionized naval (and later aerial) navigation. The term ''wikt:chronometer, chronometer'' was coined from the Greek words () (meaning time) and (meaning measure). The 1713 book ''Physico-Theology'' by the English cleric and scientist William Derham includes one of the earliest theoretical descriptions of a marine chronome ...
