The Great INDIAN Scientist


No one knows about the scientist who was already discovered the god particles

Let us know about him 

The Great scientist name was Satyendra Nath Bose 












Born: January 1, 1894
Died: February 4, 1974
Achievements: Famous for "Bose-Einstein Theory". A subatomic particle Boson has been named after him. Honored with "Padma Bhushan". 

Satyendra Nath Bose was an outstanding Indian physicist. He is known for his work in Quantum Physics. He is famous for "Bose-Einstein Theory" and a kind of particle in atom has been named after his name as Boson.

Satyendranath Bose was born on January 1, 1894 in Calcutta. His father Surendranath Bose was employed in the Engineering Department of the East India Railway. Satyendranath was the eldest of his seven children.

Satyendra Nath Bose had his schooling from Hindu High School in Calcutta. He was a brilliant student. He passed the ISc in 1911 from the Presidency College, Calcutta securing the first position. Satyendra Nath Bose did his BSc in Mathematics from the Presidency College in 1913 and MSc in Mixed Mathematics in 1915 from the same college. He topped the university in BSc. and MSc. Exams.

In 1916, the Calcutta University started M.Sc. classes in Modern Mathematics and Modern Physics. S.N. Bose started his career in 1916 as a Lecturer in Physics in Calcutta University. He served here from 1916 to 1921. He joined the newly established Dhaka University in 1921 as a Reader in the Department of Physics. In 1924, Satyendra Nath Bose published an article titled Max Planck's Law and Light Quantum Hypothesis. This article was sent to Albert Einstein. Einstein appreciated it so much that he himself translated it into German and sent it for publication to a famous periodical in Germany - 'Zeitschrift fur Physik'. The hypothesis received a great attention and was highly appreciated by the scientists. It became famous to the scientists as 'Bose-Einstein Theory'.

In 1926, Satyendra Nath Bose became a Professor of Physics in Dhaka University. Though he had not completed his doctorate till then, he was appointed as professor on Einstein's recommendation. In 1929 Satyendranath Bose was elected chairman of the Physics of the Indian Science Congress and in 1944 elected full chairman of the Congress. In 1945, he was appointed as Khaira Professor of Physics in Calcutta University. He retired from Calcutta University in 1956. The University honored him on his retirement by appointing him as Emeritus Professor. Later he became the Vice Chancellor of the Viswabharati University. In 1958, he was made a Fellow of the Royal Society, London.

Satyendra Nath Bose was honored with 'Padmabhusan' by the Indian Government in recognition of his outstanding achievement. He died in Kolkata on February 4, 1974.

Hawking's




                           Where do we come from?  

                           How did the universe begin?                             

                          Why is the universe the way it is? 

                           How will it end?





                 "All my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.  The questions are clear, and deceptively simple. But the answers have always seemed well beyond our reach. Until now.


              "The ideas which had grown over two thousand years of observation have had to be radically revised.  In less than a hundred years, we have found a new way to think of ourselves.  From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy. And our galaxy itself is just one of billions of galaxies, in a universe that is infinite and expanding. But this is far from the end of a long history of inquiry.  Huge questions remain to be answered, before we can hope to have a complete picture of the universe we live in.


              "I want you to share my excitement at the discoveries, past and present, which have revolutionized the way we think. From the Big Bang to black holes, from dark matter to a possible Big Crunch, our image of the universe today is full of strange sounding ideas, and remarkable truths. The story of how we arrived at this picture is the story of learning to understand what we see."
