The Story of Bangladeshi Scientist

When we were children we were very careful to pluck leaves or break branches. Because since that birth I have heard scientist Jagdish Chandra Bose saying that trees have life, trees also feel pain like humans. It is not that the words of all the scientists of the world were taken as such, but the words of Jagdish Chandra Bose had a different importance because he was a Bengali. 

Not only that Bengali - he was born in our Munshiganj, Bangladesh. Growing up, I learned that it is true that trees have souls, but trees do not have nerves like humans, so they feel pain, which is not entirely true. 

The prevailing belief at the time was that information was transmitted through chemical reactions in trees, but Jagadish Chandra Bose showed that it was actually transmitted through electrical signals. About a hundred years ago, it was not an easy task for a scientist in our country to come up with such a research.

We remember Jagdish Chandra Bose, read about him in books, discuss him, mainly because he is a Bengali scientist. People of other countries of the world have no reason to discuss him. But since 1998, his name is suddenly coming up in the scientific circles because a groundbreaking report was published in the proceedings of IEEE that year, in that report it is written that the real inventor of radio is not Marconi, but the real inventor of radio is our Bengali scientist Sir Jagdish Chandra Bose from Munshiganj. 

Marconi is called the inventor of radio because in 1901 he was the first to send a signal across the Atlantic Ocean without wires. In 1901, the radio was nothing like the small device we put in our pocket to listen to music or news today. The antenna used to transmit the signal was about two hundred feet high, required 25 kilowatts of electricity to run it, and the capacitor inside was about the height of a man!

What was used to listen to the signal was even more amazing! An antenna about four and a half hundred feet long had to be flown into the sky by a kite to pick up the signal. The wireless signal across the Atlantic Ocean was so weak that it required very delicate equipment. This historic experiment would never have been possible had it not been for sophisticated equipment. 

The device Marconi used to perform this delicate experiment was called a coherer. The coherers then used did not work very well – immediately after receiving a signal the coherer had to be hit with a small hammer to prepare for the next signal. The coherer that Marconi used in his experiments was the very essence of the process of sending radio or wireless signals. 

Neither Marconi nor any of his contemporary scientists ever forgot to admit that it was actually discovered by the scientist Jagdish Chandra Bose! Therefore Marconi's name has entered the world of science instead of Jagadish Chandra Bose as the discoverer of radio.

Interestingly, about ten years before this, in 1899, the scientist Jagadish Chandra Bose read an article about this coherer at the Royal Society of London. Many of the machines he built are kept at the Bose Institute in Kolkata. History bears witness that long before Marconi, he sent wireless signals to Calcutta. 

If this is true, the question may arise in the minds of common people, then why is there no name of Jagadish Chandra Bose as the inventor of radio in the history of the world? The answer is very simple, the main problem is Jagdishchandra Bose himself! After Marconi's historic experiment in 1901, Jagdish Chandra Bose wrote a letter to poet Rabindranath Tagore, the reason becomes clear. The original letter was probably written in Bengali, from its English translation back into Bengali, it looks like this:

“Shortly before my speech the millionaire owner of a very famous telegraph company sent me a telegram saying that he wanted to see me on a very important matter. I told him I don't have time. He replied that he was coming himself, indeed he came to meet me in a few moments, a patent form in hand. 

He came and strongly requested me that I should not share all the information of my research in today's speech. He said, "There is a lot of money in it! Let me get you a patent, you can't imagine how much money you're throwing away. Etc etc”, the man informed me of course, “I will only take half of the profit, the whole cost is mine etc!” This millionaire man came to me with folded hands like a beggar just to make some more money. 

My dear friend, if you only see the greed and lust for money of the people of this country! Money money and money - what ugly greed! Once I fall into this money trap, I can never get out of it. You must understand that the research I do is not for commercial purposes. I'm getting old, I don't even have time to do the things I want to do these days. So I sent the man away without saying anything."

This is the gist of his letter – a reading reveals that Scientist Jagdish Chandra Bose had no ambition for money or fame. Therefore, the results of the research that could be earned by patenting millions of rupees, he announced the results in front of everyone at the meeting of the Royal Society. Among other things, he designed a new type of coherer, placing a bit of mercury between two pieces of metal sheet. 

Marconi was an enterprising man – he made a very minor change to Jagadish Chandra Bose's design and patented it. Jagdishchandra Bose's Kohera was like the English U (U), Marconi's Kohera was straight – everything else was the same inside! By taking out the coherer, he made his name in history by sending the first radio signal across the Atlantic Ocean.

Starting from 1901, the world's scientists never once mentioned Jagadish Chandra Bose's name while discussing Marconi's groundbreaking radio wave experiments! How is it that a brown-skinned Bengali scientist will take the honor of inventing radio or wireless communication when white-skinned people control all the knowledge of the world?

So there was no discussion about it for almost a hundred years. Finally, in 1998, the truth was revealed in a new way in the history of science. The entire history is detailed in the journal I Triple Year, the world's most important engineering organization (IEEE). 

It is acknowledged for the first time that Marconi made his radio communications using the coherer invented by Jagdish Chandra Bose. So the discoverer of radio alone is Marconi the discoverer of non-radio together with our Munshiganj Bengali scientist Jagdishchandra Bose! The matter has not yet reached everywhere, the new era is the era of information exchange, so it is only a matter of time when we see the people of the world chanting the name of Jagadish Chandra Bose before they chant the name of Marconi as a radio discoverer!

Sir Jagdishchandra Bose did many things first! Everyone knows that he wrote the first science fiction of Bengali literature? His first science fiction was published in 1896 – titled 'The Story of Niruddesa'!

Sometimes it seems that rediscovering its place in the history of the world is really a story of no purpose.
