e-Learning, or electronic learning, is the delivery of learning and training through digital resources. Although e-Learning is based on formalized learning, it is provided through electronic devices such as computers, tablets and even cellular phones that are connected to the internet. Now a days due to covid pandemic many of the people used to study e-Learning method. It is useful for us to save our time. 

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...

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 ...

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 ...

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...
