CONTRIBUTION OF THE SCIENTISTS #6 CURIE

Image
Marie Curie Marie Sklodowska Curie (1867 – 1934) was a Polish-born French scientist, who is one of the most famous women in the field of science. Her work on radioactivity paved the way for future scientific as well as medicinal advancements. Coming from a family of teachers, Marie deeply believed in the importance of a good education. She studied Physics and Mathematics at the Sorbonne University in Paris. Curie is most famous for her work on radioactivity along with her discovery of two radioactive elements, Radium and Polonium. Marie Curie often worked along with her husband, Pierre Curie, who unfortunately died in 1906 in a road accident. Curie is the first woman to have ever won a Nobel Prize and the only person till date to have won it twice in two different disciplines of science. Her contributions are not only limited in the laboratory and not many are aware of the important role she played in the First World War. Know more about her scientific accomplishments of Marie Curie th...

CONTRIBUTION OF THE SCIENTISTS #5 BOSE

Image
J. C. BOSE After completing his degree, Bose returned to India and took a position as a professor of physics at Presidency College in Calcutta. Although he taught classes at the college, there were no adequate research laboratories there, so he was forced to fund his own research and perform experiments in his home. In addition, because he was Indian, his salary was much less than that of the other, primarily British, professors. When he discovered this, he refused to take any more money and worked for free for three years. Although this made for a difficult few years for Bose, things would get better. Eventually, the college decided to pay him the full salary for the three years he had worked for free and to continue paying him at the same rate as the other professors. Despite the difficulties he faced, Bose persevered and continued working. During the early years of his career, his research focused primarily on improving radio technology, specifically on the transmission ...

CONTRIBUTION OF THE SCIENTISTS #4 C. V. Raman

Image
C. V. Raman On 28th February 1928, Raman leads an experiment at the IACS (Indian Association for the Cultivation of Science) in Kolkata with collaborates including K.S Krishnan, on the scattering of light. When he discovered what now is called Raman Effect. It was initially clear that this discovery was of huge value. It gains further proof of the quantum nature of light. Raman Spectroscopy came to base on this phenomenon and Ernest Rutherford referred to it in his presidential address to the Royal Society in London 1929. Raman also worked in the acoustics of musical instruments. He worked out the theory of transverse vibration of the bowed strings, based on the superposition of velocities. He was also the first to investigate the harmonic nature of the sound of Indian drums such as table He is also interested in the properties of other musical instruments based on forced vibration such as the violin. He also investigated the propagation of sound in whispering galleries, Raman work on ...

CONTRIBUTION OF THE SCIENTISTS #3 Bhor

NEILS BHOR Active in the nineteenth century, Niels Bohr (1885 – 1962) was a Nobel Prize winning Danish physicist who made several important contributions to science including his revolutionary model of the atom, complementarity principle, Copenhagen interpretation of quantum mechanics and the liquid drop model explanation of nuclear fission. Know more about his discoveries, theories and other accomplishments as a scientist by studying his 10 major contributions to science     HE DISCOVERED THE BOHR–VAN LEEUWEN THEOREM IN 1911 Niels Bohr worked on his PhD thesis during 1910 – 1911, in which he discovered the Bohr–van Leeuwen theorem. Later rediscovered by Dutch physicist Hendrika Johanna van Leeuwen, the theorem states that when statistical mechanics and classical mechanics are applied consistently, the thermal average of magnetization is always zero. The importance of Bohr’s discovery is that classical physics does not allow for such things as paramagnetism, diamagnetism and f...

CONTRIBUTION OF THE SCIENTISTS #2 Newton

NEWTON Nature and nature’s laws lay hid in night God said, “Let Newton be” and all was light. — Reads the epitaph for Sir Isaac Newton written by poet Alexander Pope. He discovered the Laws of Gravity and motion and invented the Calculus. But, Newton’s childhood did not give a clue to what was to come. He was a posthumous child, his father had died a few months before he was born. His father’s name was Isaac Newton as well. Newton senior was a farmer and could not even sign his name, according to sources. Junior was a premature baby and his mother said he could fit in a quart mug. She remarried before the boy turned three and so little Isaac was brought up by his grandmother. His stepfather died when Isaac was 10 and he moved in with the extended family of mother, grandmother and half-brothers and half-sister. Mother wanted him to take care of the estate, but Isaac was not interested. Thanks to an uncle, he was sent back to Free Grammar School to complete his education.Isaac entered Ca...

CONTRIBUTION OF THE SCIENTISTS #1 Einstein

Image
ALBERT EINSTEIN Quantum Theory of Light: Albert Einstein Quantum theory of light proposed that light is composed of small packets of energy called photons that have wave-like properties. In the energy, he also explained the emission of electrons from some metals is struck by lightning-this was called the photoelectric effect. This theory later led to the invention of the tv, the mobile, which gave technologists a vision to return up with a modern-day screen device (Smartphones, Computer, Laptops). E=mc² He demonstrated the link between mass and energy that lead to Nuclear energy today. Brownian movement This might far and away be the simplest Einstein discoveries, Where his observation of the Zigzag movement of particles in Suspension, It helps to prove the existence of atom and molecules and we all know how fundamental his discoveries is to almost every branch of science today.  Manhattan Project Albert Einstein created the Manhattan Project research supported by the U...
