GREAT SCIENTISTS AND THEIR INVENTIONS

1. Michael Faraday

Michael Faraday was a British chemist and physicist who lived in the 19th century and became eminent as the ‘Father of Electricity. Electrochemistry and electromagnetism were his fields of work. In 1831, he disclosed electromagnetic induction which is the principle behind the working of electric transformers and generators. This discovery spotted electricity as a firing new technology. Faraday was involved in the coinage of certain terms like electrode, cathode, and ion. He discovered the laws of electrolysis and invented electromagnetic rotary devices.

2. Charles Darwin

Charles Darwin was an English naturalist who became distinguished for his idea on evolution. In 1831, he went for a sail on the HMS Beagle that spanned for five years. The job envisaged on him was to collect plant and animal specimens from the visited countries. The god part of the stay was spent in the Galapagos Islands which was the home of diverse plants and animals that can’t be found anywhere else. In 1859, Charles Darwin published a book named ‘On the Origin of Species’ which asserts that all species of life have evolved from common ancestors over time. Also, he proposed the theory of natural selection.

3. Louis Pasteur

Louis Pasteur is one of the important scientists in the world of science. He was a French chemist and microbiologist who made tremendous contributions in the study of the immune system, chemistry, and nature of diseases, and vaccination production. Pasteur showed that it’s microorganisms that cause diseases. Also, he investigated how milk and wine are spoiled by microbes like bacteria and brought up the remedy of heating such beverages. This method is known as `Pasteurisation’ that kills microbes in liquids and allows the beverages to last longer and be safer. He also produced vaccination for rabies thus saved a young lad in 1885. Louis Pasteur also made breakthroughs in chemistry by discovering the molecular basis for the asymmetric nature of certain crystals and made innovations related to the nature of tartaric acid.

4. Nicolaus Copernicus

Copernicus was the most influenced astronomer, mathematician, translator, and physicist who lived during the 15th century. He was best known as the first astronomer to put forward the idea that planets and planetary spheres circle the sun and he innovated a model of the planetary system based on this theory. This model was acceptable due to its accuracy and clarification and he proposed a formula for the calculation of the positions of planets at different times. The Roman Catholic Church questioned Copernicus’ theories and banned his book named `De Revolutionibus Orbium Coelestium’ and it was remained barred for about three hundred years after his death.

The hard work and dedication of all these scientists should be remembered as they are the ones who made our lives easy and effortless.
