In this universe, Science has given us answers to many unknown questions. Those who are behind these are scientists. Every invention is important and has played a role in advancing human civilization. Some of these discoveries are more important. The inventors of these inventions changed the world.

When the current generation is asked to know the names of two or four world-famous scientists, the first answers that usually come are Sir Isaac Newton, Einstein, Stephen Hawking. But a great scientist born on this land of Bengal who has recognition at home and abroad, a patriotic and pure man, the great scientist Jagdish Chandra Bose rarely comes first. Jagdish Chandra Bose changed Europe and America's view of the Indian subcontinent. As a scientist he was equal to Newton or Galileo.

It is his work that defines him. Einstein said of him, Jagadish Chandra should set up a victory pillar for any of the invaluable information he has gifted to the world. This man is the father of science in the Indian subcontinent. We all know this man as the scientist who proved that plants have life. In practical terms this is a very brief description of it. Because people may have had an idea that trees have life. Trees are born, grow and die. But Jagdish Chandra Bose clarified how the tree responds when hit. To know him, to recognize him, it is necessary to know about him in detail.

A scientist spends all his life time and money to excel in science. His research work, his pursuit of science put him in the ranks of famous scientists. Today we use many things including mobile, laptop, Bluetooth e.t.c. Jagdish Chandra Bose's contribution is behind all this. Again, we all know the name of the scientist Markani as the inventor of radio. But before that he explained about electromagnetic waves. Scientist Jagdish Chandra Bose's patriotism is evident from his biography. This scientist, ranked seventh in the BBC Bengal survey, was born on November 30, 1858 in Mymensingh. His family's original residence was Rahikhal in Vikrampur. His father's name is Bhagwan Bose. Bhagwan Bose served as a head teacher and later as Deputy Magistrate at various places. Although working as a government official, his passion for Bengali language was deep and from there he enrolled his child in Mymensingh District School. In that case, his argument is that he thought that in order to learn English, native children should learn their mother tongue. Jagdish Chandra Bose passed BA from St. Xavier's College in 1879.

Then, with his father's wish and interest, he went to London in 1880 to study medicine but could not continue his studies for long due to illness. He returned to India in 1885. Jagadish Chandra Bose was a man of great self-respect, self-awareness and self-confidence. This is evidenced by his return to India, where he joined the Presidency College as a Professor of Physics. But he was given no proper facilities for research there and was paid less than half the salary of European professors. In protest, he stopped taking a salary from it and continued to teach for three years without pay. As a result of his protest, his salary was made equal to that of Europeans. He was a science loved and minded man.

Although there was no suitable environment in the college, he continued his scientific research. Within a year of joining there, he emerged as a pioneer in wireless research. In 1887, he got married to Abla Bose, daughter of Durga Mohan Das, a famous reformer of Brahmo Samaj. At that time he was in financial crisis due to various reasons. Jagdish Chandra Bose spent eighteen months researching microwaves at Presidency College. In 1895 he succeeded in creating microwaves and transmitting them from one place to another without wires.

The triumph of microwaves in science today, the use of microwaves in radar, television and space communication, came from the invention of Jagdish Chandra Bose. The lecture he gave to the British Association entitled 'On Electric Waves' amazed and astonished everyone. It was written in the Times periodical about this, the most significant thing in the meeting of the British Association this year is Professor Bose's speech about electric waves.

A graduate of Calcutta University, an MA from Cambridge and a Doctor of Science from London University, the fundamental research done by this scientist on the convergence of the universe has sparked interest in the European scientific community. The paper on the determination of wavelength and refraction of electric rays was highly commended by the Royal Society.” Through this, Jagdish Chandra Bose earned the respect of world-renowned scientists. From 1899 to 1907, he researched on the reactions of organisms and inanimate objects. He was the first to reduce electromagnetic wave lengths to millimetres. The issue of patriotism came up again and again in his speech.

In 1927, the then Vice-Chancellor of Mysore University, Professor Brajend On the invitation of Ranath Sheel, speaking at the convocation ceremony of that university, he said about "the trend of education in India" - geographical barriers in the promotion of education have never been able to create any obstacles in India. If we look at the past, we can see that the immortal Acharyas are still alive and encouraging us. I see, Acharya Sanka also came out victorious under the influence of scholars and conquered all the countries starting from the south and ending at the end of northern India.

I see the scholars of Bangladesh crossing the Himalayas with only a few palm leaves. This statement has more parts. Jagdish Chandra Bose has another identity. That is his identity as a writer. He wrote a science fiction story called ``Niruddesh''. One of his famous books is called 'Abyakta'. He was the first to invent the technology of transmitting sound wirelessly. That is why the Institute of Electrical and Electronics Engineers called him the father of radio science. Jagdish Chandra Bose has made important contributions to the information and communication technology that the world is talking about today. His contribution to the future development of science is also undeniable.

He established the 'Vasu Vigyan Mandir' in Kolkata on 30 November 1917 for research on plant physiology. He spent all the money he earned in his life to build this laboratory and buy the necessary materials for it. In 1858, on the occasion of Jagadish Chandra's birth centenary celebrations, the West Bengal government launched a scholarship called "JBNSTS". He was knighted in 1916, Fellow of the Royal Society in 1920, Member of the Vienna Academy of Science in 1928 and President of the 14th session of the Indian Science Congress in 1927 for his outstanding contribution to science. This great scientist died on 23 November 1937.
