Srinivasa Ramanujan

Biography of Srinivasa Ramanujan

Born on 22nd December 1887 in Tamil Nadu, Ramanujan was an eminent mathematician who had made significant contributions in mathematical analysis, infinite series, number theory and continued fractions. An independent mathematician, he developed original and novel results such as the Ramanujan theta function, the Ramanujan prime, mock theta functions, partition formulae etc. A scientific journal was established to publish research in all the areas influenced by him, named The Ramanujan Journal. He was the first Indian to be elected a fellow of the Trinity College, Cambridge and was one of the youngest fellows of the Royal Society. Ramanujan died on the 26th of April, 1920.

National Science Day 2021: Know History, Significance,

National Science Day is celebrated every year on February 28 across the nation to mark and recognise the contributions of scientists towards the development of the country. National Science Day is held to commemorate the discovery of the Raman Effect. On February 28, 1928, Sir CV Raman discovered Raman Effect for which the Physicist was awarded the Nobel Prize in 1930. The theme for this year’s National Science Day celebration is “Future of STI: Impacts on Education, Skills and Work”. Raman Effect is the phenomenon in spectroscopy discovered by Sir Chandrasekhara Venkata Raman while working in the laboratory of the Indian Association for the Cultivation of Science, Kolkata. National Science Day 2021 Theme The theme for this year’s National Science Day celebration is “Future of STI: Impacts on Education, Skills and Work”. The theme this year has been chosen for the purpose of raising public appreciation of the scientific issues involved and the impacts science has on educat...

What do you feel when rubbing together your palms against each other? If you rub your hands together for several seconds, you'll notice that your hands feel warm . That warmth is caused by a force called friction. ... Friction happens when you overcome the resistance of one object rubbing against the other. The force of the friction is opposes the direction of the motion

Physics

Physics 'Knowledge of nature' Who named Physics? The History of Physics - Before Aristotle: Atomism and Natural Laws. Thales was the first physicist and his theories actually gave the discipline its name. He believed that the world, although fashioned from many materials, was really built of only one element, water, called Physis in Ancient Greek. Physics is considered to be one of the primitive subjects and academic disciplines to be discovered. It encompasses the study of matter, its motion and behaviour along with energy and force. As a vast discipline, it intersects with many different subjects and disciplines such as biophysics and quantum chemistry. Physics very often defines a wide range of principles and methodologies studied by other areas of sciences. It also suggests new areas of research for other academic fields, even mathematics and philosophy . Branches of Physics 1:Classical Physics Among the popular branches of ph...

Salim Ali

Biography of Salim Ali Popular as the Birdman of India, Salim Moizuddin Abdul Ali was born on the 12th of November, 1896 in Bombay, Maharashtra. A naturalist and ornithologist, Salim Ali was the first Indian who conducted systematic surveys on birds across India. He played an important role in the establishment of the Bharatpur bird sanctuary, along with contributing to the development of the Bombay Natural History Society which made him one of the profound Indian scientists. For his contributions, the Indian Government awarded him with the Padma Bhushan and the Padma Vibhushan in 1958 and 1976 respectively. He wrote the ten-volume Handbook of the Birds of India and Pakistan in association with the American ornithologist, Sidney Dillon Ripley. Salim Ali died on the 20 of June 1987.

C.V. Raman

Biography of C.V. Raman Chandrasekhara Venkata Raman was an eminent Indian physicist who had immense contributions in the field of light scattering. He was born on 7th November 1888 in Trichy, Tamil Nadu and is best known for his discovery of the phenomenon of scattering of light which is famously known as the Raman effect. He was awarded the Nobel Prize in Physics for his work in 1930, making him the first Indian or Asian to receive the prize in any branch of science. He was honoured with the highest civilian award by the government of India, the Bharat Ratna, in 1954. C.V. Raman died on 21st November

Chemistry

Chemistry is the scientific study of the properties and behavior of matter.[1] It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).

Aryabhatta

You will be surprised to know that a lot of scientific knowledge was evolved in ancient India, so many years ago. During this period Science and Mathematics were highly developed and Ancient Indians had contributed immensely. Ayurveda is the indigenous system of medicine that was developed in Ancient Period. Even the science of Yoga was also developed as an allied science of Ayurveda. In this article we will see the contributions of some scientists of ancient India. 1. Aryabhatta He was a fifth century mathematician, astronomer, astrologer and physicist. - At the age of 23, he wrote Aryabhattiya which is a summary of mathematics of his time. - First time he had calculated the value of pi at 3.1416. - He showed that zero was not a numeral only but also a symbol and a concept . Infact the discovery of zero enabled Aryabhatta to find out the exact distance between the earth and the moon. And zero discoveries opened a new dimension of negative numerals. ...
