Great scientists of the world and their inventions pdf
Is Science Stagnant? - The AtlanticLouis Pasteur , born December 27, , Dole , France—died September 28, , Saint-Cloud , French chemist and microbiologist who was one of the most important founders of medical microbiology. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization ; saved the beer , wine , and silk industries in France; and developed vaccines against anthrax and rabies. He also disproved the theory of spontaneous generation and contributed to germ theory and the study of infectious disease. Louis Pasteur is best known for inventing the process that bears his name, pasteurization. Pasteurization kills microbes and prevents spoilage in beer, milk, and other goods.
10 Famous Indian Scientists and their Inventions -- TTL
The 10 best physicists
This list of Indian inventions and discoveries details the inventions, scientific discoveries and contributions of India, including the ancient, classical and post-classical nations in the subcontinent historically referred to as India and the modern Indian state. It draws from the whole cultural and technological history of India, during which architecture , astronomy , cartography , metallurgy , logic , mathematics , metrology and mineralogy were among the branches of study pursued by its scholars. For the purposes of this list, inventions are regarded as technological firsts developed in India, and as such does not include foreign technologies which India acquired through contact. It also does not include technologies or discoveries developed elsewhere and later invented separately in India, nor inventions by Indian emigres in other places. Changes in minor concepts of design or style and artistic innovations do not appear on in the lists.
A crowd barged past dioramas, glass displays and wide-eyed security guards in the American Museum of Natural History. Screams rang out as some runners fell and were trampled. Upon arriving at a lecture hall, the mob broke down the door. The date was Jan. Einstein was not present, but 4, mostly ticketless people still showed up for the viewing. As a publicist might say, he was the whole package: distinctive look untamed hair, rumpled sweater , witty personality his quips, such as God not playing dice, would live on and major scientific cred his papers upended physics.
Historians and sociologists have remarked the occurrence, in science , of " multiple independent discovery ". Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton , Gottfried Wilhelm Leibniz and others, described by A. Rupert Hall;  the 18th-century discovery of oxygen by Carl Wilhelm Scheele , Joseph Priestley , Antoine Lavoisier and others; and the theory of the evolution of species , independently advanced in the 19th century by Charles Darwin and Alfred Russel Wallace. Multiple independent discovery, however, is not limited to such famous historic instances. Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science.

How often do we take out the time to think about those extra ordinary minds who made life easier for us? Raman also worked on the acoustics of musical instruments. He was the first to investigate the harmonic nature of the sound of the Indian drums such as the tabla and the mridangam. He discovered that, when light traverses a transparent material, some of the deflected light changes in wavelength. This phenomenon is now called the Raman scattering and is the result of the Raman effect. In October , he collapsed in his laboratory. He was moved to a hospital and the doctors gave him four hours to live.
Scientists are persons of great minds, who ask question about the phenomenon and systematically answer the question themselves. No doubt, they are curious, creative and well organised. They have the ability to observe new things in a different way. Their discoveries have change the world and gave it a new dimension. It is correctly said by George C.
