Born on June 13, 1773 at England, Thomas Young who revived the wave theory of light propounded by Christian Huygens, was also a child prodigy able to read at the age of 2. He had read through the Bible twice by the time he was four. Though he attended two boarding schools between 1780 and 1786, he was largely self-taught. Thomas Young was the first to show that colour sensation in eyes is due to the presence in the retina of the structures which corresponds to three colours – red, green and violet and there is no need for a separate mechanism in the eye for every colour. His contribution was formulated into a proper theory of vision by Helmhotz (1821-1894). This three-contour theory is used in colour television and colour photography.

Boren in London on June 13, 1854, Charles Parsons was the first engineer in England to be admitted to the celebrated decoration, Order of Merit. He patented his several innovations in the domain of turbines. His innovation of allowing steam to expand across the turbine blades resulted in significant improvement in the performance of his steam turbines. Parson’s turbines worked at 18,000 revolutions per minute (rpm) while the electrical generators worked at 1500 rpm. From 1894, Parsons turned to the application of his turbines to ships which achieved initially a speed of 20 knots. Soon the turbine became standard in British warships from 1905.For insightful knowledge on national and international science, explore @startoutreach#CharlesParsons #SteamTurbine #EngineeringPioneer #PowerRevolution #MarineTech#EnergyHistory#IndustrialInnovation#OnThisDay #Turbinia #EnergyEngineering#SteamPower #LegacyOfParsons … See MoreSee Less
Born on June 10, 1832, Nikolaus Otto, as a self-taught technologist, brought to a successful conclusion two centuries of experiment to harness the energy resulting from an explosion in a closed cylinder. The principle employed was that of the double-acting steam engine. Instead of steam, gas and air were successively admitted at each end of the cylinder. Nikolaus Otto came out in 1876 with the patent for his four stroke engine. In 1877, he introduced a horizontal engine. More than 30,000 engines were sold in the first ten years of manufacture . the invention of the free-float carburettor by Wilhelm Maybach allowed petrol to be used as a fuel instead of gas.

Born on June 10, 1959, Siva Umapathy, a fellow of the Royal Society of Chemistry and the 2004 winner of Shanti Swarup Bhatnagar Prize for his contribution to chemical sciences, attempted to find unique signatures in cells called ‘bio-markers’ which are like fingerprints that could help in early cancer detection. After a long stint at the Indian Institute of Science, he served as the Director of Indian Institute of Science Education and Research, Bhopal, from 2028 to 2023.

Born on June 9, 1781, George Stephenson in England, George Stephenson was the inventor of the steam locomotive. Following the invention of the steam engine by James Watt (1736-1819), George Stephenson pioneered the building of the first railway in England which marked a milestone in the history of surface transportation. He learned to read and write at the age of 17, by attending evening classes. Stephenson’s first invention was a safety lamp for miners (1815), which was developed at about the same time by Humphrey Davy (1778-1829). He tested it in the gas-infected tunnels. This led to a controversy as to who was the real inventor, but before long it was acknowledged that both men reached the same goal by different approaches.
