Who invented dynamite?
In the middle of the 19th century, a famous Swedish scientist named Dr. Alfred B. Nobel invented dynamite. He was an engineer and chemist. His invention caused a huge response all over the world at that time. As soon as dynamite was discovered, there was a response all over the world and everyone started praising Nobel. By selling dynamite, the devotee Nobel got a lot of money. At the time of his death, he had made a “will” that five “prizes” or awards would be given every year from the interest of his accumulated money.
Five people who are considered the best in the world in five different subjects every year would receive the awards. Out of these five subjects, one was physics, one was chemistry, one was physiology or medicine, one was literature and the fifth was about establishing peace.
Who got the first Nobel prize in India?
Since the death of Dr. Nobel, many great intellectuals from different countries have been considered the best in the world and have received this world-famous prize as a sign of this. In our country too, two great intellectuals have received this honor. First, the world-famous Bengali poet and writer Rabindranath Tagore received the “Nobel Prize” in 1913 for being considered the best in the world in poetry and literature. Later, the Madras physicist Chandrashekhar Venkata Raman received this award in 1931 for being the best in physics.
Dynamite, dry-cell, beet sugar, stainless steel, electroplating, soda, air and the animal and plant world, kachuripana, hydro-electricity, lignites, methane, rayon etc. have been beautifully illuminated in this book ‘Kajer Bigyan’.
