The great biologist, who showed those plants, too can feel in their own way. He saved money: he bought a small laboratory and built his equipment, and scientists in Europe and America wondered at his discoveries. A true patriot and a great man.

He is still relevant that Google dedicated a day’s doodle with this great scientist.

Suppose there is a lush green plant and its leaves are a sparkling green in the shining sunlight. We feel like pulling out a leaf to feel it. But we do not think of what goes on inside the plant.

Maybe, we feel that the plant does not suffer like us. But the plant does suffer. In fact, the pulsation of the plant stops where the leaf was plucked.

In a short time the pulsation again begins at the spot, but this time very slowly. And then it completely stops. That spot is as good as dead for the plant.

It was Jagadish Chandra Bose, an eminent Indian scientist, who explained that plants also suffer pain like us. Though he worked in other fields of science, he is best known for his research into the life of plants.

The Parents

Jagadish Chandra Bose was born on the 30th of November 1858 in Faridpur in Dacca District.

Faridpur was a part of India until 1947; now it is in Bangladesh. His mother Abala Bose was a tender-hearted and affectionate woman. His father Bhagawanchandra Bose was a man of excellent qualities. Bhagavanchandra Bose was Deputy Magistrate of Faridpur. He helped very generally the poor and the needy. He would comfort people in sorrow. There was a famine in Bengal in the year 1880. Bhagavanchandra Bose spent his own money to help the poor villagers.

In the year 1874, hundreds of families suffered because of widespread malaria. Thousands of children lost their parents and became orphans.

Bhagawanchandra Bose helped these orphans.

He spent money from his pocket to start a factory. But he never regretted doing so.

Early Education

In the days of Jagadish Chandra Bose’s boyhood, the well educated and the well to do people were attracted by Western culture. A man was proud if he had learned English. But Jagadishchandra Bose’s education was really remarkable;

it was due to his father. As long back as a hundred years ago, Bhagawanchandra Bose started schools in which children were taught in Bengali. Jagadish Chandra also received his early education in this school. Jagadish mixed with the poor boys freely and played with them; so he gained first-hand knowledge of the sufferings of poor people.

He learned much more. He learned how the fisherfolk moved on the broad rivers in their boats, how the fishing rod was cast in the flowing water, how plowing the land and sowing seeds in it grew the crops and how the cattle were taken to graze on the distant hills. He was all ears when the fishermen and the farmers gave such accounts. He was thrilled by their adventurous life and it made him more courageous in life.

There was another interesting person in his early life. This was a servant who used to take Jagadish Chandra to school every day. He had been a dacoit in the past.

Bhagawanchandra Bose as a judge had sent him to prison. After some time the dacoit came out of prison. But how was he to live? Bhagawanchandra Bose was a very good-natured man. So he employed him as a servant. The dacoit used to tell little Jagadish Chandra events of his past life, the robberies he had committed and his cruel deeds.

His adventures made a lasting impression on the boy.

Young Bose was all curios. He wanted to know about everything that happened around him. What is glow-warm? Is it fire or spark? Why does the wind blow? Why does the water flow?

He was always ready with a string of questions.

His father would answer as many questions as he could. But he never tried to impress upon his son that he knew everything. If he could not answer a question, he would frankly tell his son so. Thus Jagadish Chandra’s parents took great interest not only in his studies but also in everything that shaped his character. They narrated stories from the Ramayana (by Valmiki) and the Mahabharatha to him (by Vyasa).

Karna of Mahabharatha was ideal for him. (Karna was a great hero but, more important still, very generous.) He went with his parents to see the performances of folk drama. (These were staged in open-air theatres.) They treated all his friends alike. Such was the environment for Jagadish Chandra in his boyhood. He grew up to be ‘ broad-minded, patriotic, obedient to elders, affectionate towards his fellowmen. He never made any distinction between the rich and the poor; all men were equal in his eyes.

Generally, it is easy to understand a subject if it is taught in the student’s language; it becomes difficult if it is taught in some other language.

Jagadish Chandra did not face this problem since he studied the subjects in his own language. He understood them easily. He was in the habit of thinking for himself whenever he studied. He learned many things on his own by studying at home. But he was not a bookworm. He was very enthusiastic about games too. Cricket was his favorite sport.

In Calcutta

Jagadish Chandra began a new chapter in his life at the age of nine. He had to leave his hometown. He went to the big city of Calcutta for further education. He was admitted to Saint Xavier School there. There was a world of difference between the previous school and this one.

In Faridpur he had studied everything in his own language. But here in Calcutta, his schoolmates knew only English. The city boys, especially the English boys, teased him. One of them even hurt Jagadish Chandra in a bout of boxing. Jagadish was provoked and he taught the boy a well-deserved lesson. That was the end of any teasing.

While he was studying at Saint Xavier’s, Jagadishchandra was staying in a boarding house. He had no friends and was lonely here.

But he was a born scientist. Even as a boy he had many hobbies that showed his scientific interest. He used to breed frogs and fishes in a pond nearby. He would pull out a germinating plant and observe its root system. He had also a number of pets like rabbits, squirrels and non-poisonous snakes. Even in Calcutta, he continued these hobbies to get over his solitude. He grew flower-bearing plants and had animals and birds as pets. He did well in his studies and was in the forefront. The teachers liked him for his intelligence. Jagadish Chandra passed the School Final Examination in the First Class.

He joined the B.A. class in college. In those days, science subjects formed a part of this course. He was most interested in Biology (the science of life). But Father Lafont, a famous Professor of Physics, inspired in Bose a great interest in the science of Physics and Bose became his favorite student. Even so, Bose was always interested in any branch of science. Botany, the science of plants, still attracted him much.

In London

JC Bose Early Education

By nineteen, Jagadish Chandra was a Bachelor of Arts student. He wanted to go to England for higher studies. He wished to try his luck at the Indian Civil Service Examination or to study medicine. If he entered the Civil Service, he would be a government officer. This would mean subordination; his father did not want Jagadish to work under others. And he did not have enough money to send the boy abroad. Besides, he wanted that his son should become a teacher and serve his people and his country. Even Jagadish Chandra’s mother was not quite willing to send him, because she thought it was against their religion.

She was pained at the thought that her son would be far away from her. Jagadish Chandra Bose did not wish to do anything against the will of his parents.

Finally, his good mother allowed him to go.

She had saved some money. She also wanted to sell her jewels to meet the expenses of her son’s voyage. Bhagawan Chandra Bose prevented her and he managed to find the money on his own.

At last, Jagadish was on his way to England. The year was 1880. Twenty-two-year-old Jagadishchandra Bose stepped into the ship; he was stepping into a new phase of life which laid the foundations of a brilliant future.

In London, he first studied medicine. But he repeatedly fell ill. So he had to discontinue the course. He then studied Natural Science at Christ Church College, Cambridge. It was necessary to learn Latin in order to study Natural Science; Jagadish had already learned it. He passed the Tripos Examination with distinction. In addition to the Cambridge Tripos Examination, he passed the Bachelor of Science Examination of London University also.

The Young Scientist His Own Smith, Too

Young Scientist JC Bose

Jagadish Chandra Bose was back in India. He joined the staff of the Presidency College, Calcutta. There was a peculiar practice in that college. The Indian teachers in the college were paid one-third of what the British teachers were paid! So Jagadish Chandra Bose refused his salary but worked for three years. He could not even get the scientific instruments he needed for research. He was not shown the respect due to him. This did not continue for long. His deep knowledge zest for work and cultured behavior won over those in charge of the college. They saw to it that he was given the full salary of the post and not one-third.

Teaching the same lessons year in and year out was very tedious to Bose. His, was an alert mind, always on the lookout for new ideas. He wanted to do research, to widen his knowledge and discover new things.

A laboratory is necessary for research. Many scientific instruments are required. Jagadish Chandra Bose had no laboratory and he did not have the instruments. But he was not disheartened.

For eight or ten years he spent as little out of his salary as possible, lived a very strict life, saved money and bought a laboratory!

Generally, Marconi’s name is associated with the invention of wireless. (This made possible the use of the radio.) Jagadish Chandra Bose had also conducted independent research in the same field. Marconi was able to announce the result of his work and show how wireless telegraphy worked, earlier than Jagadish Chandra Bose.

So he is called ‘the father of the radio’. In the year 1896 Bose wrote a research article on electromagnetic waves. This impressed the Royal Society of England (which is famous all over the world). He was honored with the Degree of Doctor of Science. He needed money to continue his work. Bengal, his homeland, came forward to bear the expenses. Those were the days when the British Government would not help an Indian to go abroad for studies. Bose had the honor of getting encouragement even from the British Government and he made excellent use of this.

Bose became famous in the world of science.

In India and in other countries there was a strong belief that only Westerners could achieve anything worthwhile in science. Bose proved this concept wrong. He showed that there were geniuses elsewhere too. He visited England again, this time to explain his discoveries to the scientists of the West.

Bose needed scientific equipment. But the instruments he needed were not available. But this did not hamper his work. Early in his life, he had learned to make his equipment with his own hands. The scientific instruments he took to England were those he himself had made.

Electricity was then his special field of work.

He had successfully worked at transmitting electro-magnetic waves from one place to another.

He had determined the type of instruments required both at the transmitting end and at the receiving end; he had found out what the distance should be between these two ends. He was using the instruments he had himself made.

JC Bose using own instruments

Bose demonstrated his discoveries at the Royal Society in England. The gathering of scientists was profoundly impressed. They praised this achievement as a singular one from a citizen of India. Our country was until then famous only as of the home of philosophy and religion. Bose won respect for Indians in science too. The renowned papers of London namely ‘The Spectator’ and ‘The Times’ was all praise for this Indian scientist. For, without proper facilities and with the available material, Bose had achieved wonderful results and he had done his research along with his teaching work.

Fame

After he lectured at the Royal Society, scientific associations in many other countries invited Jagadish Chandra Bose. He visited France, Germany, America, and Japan besides England. He lectured at several places and explained his discoveries.

When electricity passes through a man, animal or plant, we say there is a ‘shock’. When it is passed through a living being the being gets excited, ‘irritated’. Bose developed an instrument that would show such a reaction of the organism on a graph. When electricity was passed through zinc, a non-living substance, a similar graph was obtained. So he came to the conclusion that living and non-living things were very similar in certain reactions.

In Paris, he gave a lecture on this similarity between the living and the non-living world.

Have you heard of ‘radar`? This is a very wonderful scientific device. Sailors on the sea use it; it is also used to get information about airplanes coming towards a place. So you see how useful it is during a war. If the airplanes of the enemy try to attack a city, the radar shows their movement. J.C. Bose worked out some details of very great importance; these are being used in the working of the radar. When Jagadish Chandra Bose again visited England, Cambridge University honored him as a Professor.

Generally, when a man invents something new, he declares that nobody can make use of it without his permission. If anybody desires to, make use of it, he will have to pay him money, why? Because the inventor has worked hard and he has used his time and brains for his invention.

It is not right to make use of his work without paying him. An inventor can make lakhs of rupees by just one or two inventions. Bose had invented many instruments. They have since been used by many industries. When he was offered money for these he did not accept it. He was very generous and noble; he felt that knowledge was not any one’s personal property. He permitted any one to use the fruits of his work.

The Davy-Faraday Research Institute is a very famous scientific institute for scientific research in England. This institute requested Jagadish Chandra Bose to continue his research there. Many eminent scientists pressed him to do so. Hence tie worked there for some time and discovered new things. When an outside stimulus is applied to the muscles of a man or a non-living thing (says a mineral), they respond to it. Bose wondered whether this could happen in a plant also. To test this he brought a leaf, a carrot and a turnip from the garden. He applied stimulus and electricity. It was confirmed that plants also respond in a similar way. Jagadish Chandra Bose explained this at a meeting of the Royal Society. While explaining his discoveries he said that the Indian sages had understood such principles thousands of years ago. He modestly added that his discoveries were an insignificant part of the great truth that our ancient sages had realized.

Challenges

When anything new is discovered, there will always be people who question it. The results of Bose’s work, too, were not accepted by all. There were people who challenged them and even said that there was not much truth in them. Bose gave a lecture at the Linnean Society next year to a gathering of scientists. He explained with suitable experiments about how plants respond to stimuli.

Even those who had challenged him could not find fault with his experiments or conclusions.

There is an interesting story about a demonstration that Bose gave in England. On that day he wanted to show some new things that he had found out. He had come to the conclusion that plants can feel pain like animals; that when we pinch them they suffer; and that they die in a few minutes after they are poisoned. Bose wanted to show experiments to prove these conclusions. A number of scientists and other leading men and women had gathered to hear him. Bose started the experiments by injecting poison into a plant.

The plant should have shown signs of death in a few minutes. On the contrary, nothing happened. The learned audience started laughing.

JC Bose and his experiements

Even at this adverse moment, Bose showed admirable calmness. He thought quickly. The poison that he injected into the plant did not kill it. So, he supposed that it would not hurt him also.

With full confidence, he got ready to inject the poison into himself. At that instant, a man got up and confessed that instead of poison he had put similar colored water. Now, Bose conducted the experiment again with real poison, whereupon the plant withered and died as expected.

Jagadish Chandra Bose continued his work and made new discoveries. He found that plants shrink a little during the night. He found out why plants always grow towards light even if they have to bend. He also found out the reason why some plants grow straight and some do not. He explained that this was due to the ‘pulsation’ in plants. This pulsation quickens by heat and slows down by cold in plants.

Jagadish Chandra Bose did remarkable work, and scientists outside India had honored him.

Yet there were people who opposed him. As a result, even the Royal Society delayed publishing his valuable work in its publications, But nothing could make him give up his work. He was sure that years of research had led him to the truth.

So he did not feel that it was very necessary to depend on scientific journals only. He wrote books and published them on his own.

By this time Bose had made a name for himself as a great scientist. The instruments he had developed were being used in some Western countries too. He visited Europe and America in 1907 and 1914; scientific institutions invited him to explain his discoveries. He visited Japan also.

Most of us have seen a particular kind of plant called the mimosa (touch-me-not’) which spreads on the ground. It has very small leaves.

It is extremely sensitive. If we just touch one leaf, that leaf and the leaves nearby all fold up.

The greater the force we use, the larger the number of leaves that fold up. The whole row of leaves of the branch can be made to fold like this by touching it with a little greater force.

Why does only this plant react like this? We have often wondered, haven’t we? Bose wondered, too. And he went on to find out. He found that other plants also react to a man’s touch in the same way. The only difference is this: We cannot see the reaction of other plants but we can see the reaction of the mimosa. But Bose wanted to study the reaction of other plants, too. He designed delicate instruments that would show such reactions in them. When he went abroad he took these instruments and also some of the plants with him. It was very difficult to’ keep the plants alive in the climate of foreign countries.

Jagadish Chandra Bose showed the experiment in Cambridge and Oxford. The scientists were fascinated by the extreme sensitivity of plants; they were also filled with wonder when they saw the excellent instruments, Jagadish Chandra Bose, himself had made. No one had done work of this kind in Biology. It was news that plants could also experience different sensations like us.

Jagadish Chandra Bose continued his search for new knowledge. His achievements were many. The British Government honored him more than once. In 1915 when retired from service he was made an Emeritus Professor. He was to get Rs. 1500 a month as long as he lived.

He was honored as a Fellow of the Royal Society (F.R.S) in 1920. In 1927 he presided over the Indian Science Congress.

A New Temple

Bose had worked all along without the right Wind of scientific instruments and laboratory.

JC Bose and his own Laboratory

For a long time, he had been thinking of building a laboratory. The result was the ‘Bose Research Institute’ which is in Calcutta. Even now it is famous as a center of research. Bose had been collecting funds for this Institute for quite some time. More than sixty-five years ago, he had realized the importance of a research institution in India. While inaugurating the Bose Research Institute he said, “This is not a laboratory but a temple.” Such was his devotion to work. He felt everybody must have the same enthusiasm for research in a country. In the Bose Research Institute research is conducted in Botany and Physics – the two branches of science in which Bose had won fame.

He worked in this laboratory for 20 years, up to the very end of his life. We should not depend on others to do our work, we ourselves must do our work, but before we can do this we must get over our pride – this was his firm belief. He confessed that he had learned this lesson from his parents.

The Questioning Boy – The Great Scientist

Nature had always been a source of attraction right from an early age to Bose. There are flowers on plants; flowers give fruits; the leaves fall off; seeds germinate into new plants – we see all these around us.

But Bose was interested in these happenings, which to many people seem quite ordinary. He asked others questions; he asked himself, too:

‘How do these things happen?’ Not always could he satisfy his curiosity. But it was his way to try to find answers to any questions arising in his mind.

We may consider here the more important of his discoveries. Plants respond to stimuli from outside. We draw away hand when it touches fire. When it is extremely cold we may even die.

Plants also experience heat and cold in this way.

This can be measured with a thermometer. At 60 degrees Centigrade, a plant will faint because of the extreme heat and at very low temperatures it will react similarly to cold. Plants always react to the rise or fall of temperature in the atmosphere around them. When heat or cold is extreme, plants will faint or may even die. Bose had designed very delicate instruments that could record even this. When a plant is hurt at one point, the shock of this is transmitted to all the other parts and the whole plan gets tired and it bends down. Plants grow every second by 1/50,000th of an inch! How is this to be measured – it is so very, very, very small? Bose himself devised a delicate instrument, which could measure even this length.

Plants do not grow in a perfectly straight line.

There are small twists and turns, Why? The answer Bose found out is very interesting. He said, that plants have positive and negative charges. If one of these pushes a part of the plant-forward, the other pushes it backward. The growth of the plant is affected by these pushes and it becomes slightly curved instead of being straight. Plants grow towards light even when kept in a dark place, why? The roots of plants always grow downwards, why? Bose found answers to all this.

We all know that the lovely flower, the lotus, opens up as the sun rises in the sky. When the sun sets the lotus closes its petals. The popular belief is that this is because the lotus loves the sun. But Bose explained this peculiar behavior of the lotus. It opens when there is a rise in the temperature and closes as the temperature drops. The same is true of the sunflower. He called this peculiarity ‘the thirst for light’.

The other peculiar thing he demonstrated was the way plants behave differently at different times of the day. He established that from 6 in the morning to 3 o’clock in the afternoon, the plants behave in one way; and from 3 in the afternoon to 6 in the morning plants behave differently. As an example he chooses a palm tree in Faridpur-This palm in Faridpur would bend down every evening. The people of the place had their own explanation.

They believed that the soul of some holy man lived in the tree. Every evening when the temple bells rang, this holy spirit bowed in devotion – this was their belief. But Jagadish Chandra Bose discovered the real cause. He gave a scientific explanation. The tree bent down in the evening and raised itself in the morning because of the fall and the rise in the temperature.

Water is very essential to plants. The root of the plant absorbs water. But even without roots plants can take in water. This was demonstrated by Bose. He showed that when the root is cut and the plant stem is placed in, water it starts taking in water. Suppose you remove the plant from the soil and place it upside down (with the branches below and the roots above); what happens? The leaves and the stem absorb water. Bose proved this by means of experiments.

The cells of a plant function like a man’s heart.

The heart contracts and expands to pump blood; in the same way, the cells of a plant expand and contract.

This had to be proved by experiments. So, Bose himself devised a new instrument; this could show how the cells worked.

Spirit of Adventure

Jagadish Chandra Bose had to face many difficulties and problems in his life. But he never lost courage. He was clear, even in the most adverse situations. This was seen even in his very early years. When he was only five, he used to go to school on horseback. Once there was a local horse race. Young Jagadish Chandra was also there to watch the race. Somebody said, “Why don’t you also ride?”. The horse should be brindled and the rider should have stirrups, to ride. But young Jagadish Chandra’s horse was not even brindled.

Ever Courageous J C Bose

There were no stirrups. Yet he patted the horse and away, the horse galloped. The boy’s legs were bruised and blood flowed. But the rider and the animal completed one full circle on the race track. So young and brave, he was the center of appreciation.

There was another hazardous ride he undertook early in his youth. He had gone out hunting on horseback. While returning he had an attack of fever. He was all alone. The horse he was riding was rather a troublemaker. He started to run at full gallop. There used to be a bridge on the way, but the floods had washed away this bridge. Jagadish Chandra’s horse was heading for this broken bridge. Jagadish Chandra was very weak because of the fever. But at the very last moment, he pulled the bridle very hard.

The horse changed his course and crossed the stream on the bridge nearby.

Scientist And Man Of Letters

JC Bose and Robindranath Tagore

Jagadish Chandra Bose was famous as a scientist. He brought laurels to his motherland. But his interests were many-sided. He was especially interested in literature and fine arts. The great poet Rabindranath Tagore and Jagadish Chandra Bose were very good friends. The first time Tagore visited Bose, he was not at home. Tagore left a bunch of champak flowers. This was the beginning of their friendship.

Tagore invited Bose to stay with him for some time. Bose agreed to do so on one condition.

The condition was that Tagore should narrate a story to him every day. This is how a number of Tagore’s stories came to be written. Have you read the story ‘The Cabuliwallah’? It is a very fine story; it narrates how a deep and strange friendship grew up between a rough Pathan and a tine Bengali girl. This has been translated into several languages and is well known in a number of countries. Tagore wrote this story when Bose was staying with him. And Bose, the great scientist, was also President of the Bengali Sahitya Parishat.

Patriot and a Good Friend

We have already seen how Bose honored Indian sages of the past. Scientists of other countries praised Bose’s important discoveries; Bose used to say, “The sages of India knew all this long ago”.

He loved to visit the various shrines of India.

Accompanied by his wife he would make these trips whenever he could find the time. He used to take photographs of the places he visited and had quite a collection of these photographs.

He went to places of historical or mythological interest. The famous sculptures and the temple architecture of our land always thrilled him. He visited Sanchi, Chittorgarh, Ajmer, and Nainital as well as the cave temples of Orissa and the famous Ajanta and Ellora Caves. He visited the Puri Jagannatha Swamy Temple. He also visited well-known places of pilgrimage of South India like Rameshwaram, Madurai, and Tanjore.

He visited the shrines at the foot of Himalayas; Kedarnath particularly appealed to him.

Jagadish Chandra Bose was not a proud man.

He was simple, affectionate and warm. It is not surprising that many great persons of the day were his friends. Prafulla Chandra Ray, another famous scientist, was one of his close friends.

Eminent men like Gopalakrishna Gokhale and Mahatma Gandhi knew and respected him.

Sister Nivedita was another good friend. She was an Irish lady; her name was Margaret Nobel.

She was the disciple of Swami Vivekananda.

She settled down in India and spent her life in the service of the people of this country. She recognized the genius in Bose. Bose toiled hard to educate the people about the importance of science, and Sister Nivedita admired his efforts.

JC Bose and Sister Nivedita

So she was keenly looking forward to the birth of the Bose Research Institute. In memory of her, Bose placed in front of the Institute the statue of a woman stepping forward with a light in her hand.

He had another good friend, one Mrs. Bull.

While touring America he was her guest. She had taken care of him as a mother. When he fell ill in Paris, she traveled to Paris, made arrangements for his treatment and personally looked after him. There were two other friends of his, two giants of the literary world. They were George Bernard Shaw, the English dramatist and Romain Rol and, the French writer. Both of them dedicated one book each to Jagadish Chandra Bose.

Abala Bose, a Worthy Wife

Jagadish Chandra Bose was very busy throughout his life. He had no time to think of the problems of the household. His wife Abala Bose looked after their home all by herself; he did not have to think of the management of the house.

She was herself a student of medicine when her marriage to Bose was settled. Bose’s parents were very kind and generous; they had helped many people with money. So, at the time of Bose’s marriage, the family was in heavy debt.

Jagadish Chandra Bose had to repay the debts. So Abala Bose was very, very careful in spending money, and saved as much as possible. Unfortunately, the Bose couple had only one child, who did not live long. They looked after the students, as their children. Abala Bose started girls’ school in Calcutta and took upon herself the responsibility of maintaining it. She went with her husband when he went to foreign countries, and even helped in his scientific work.

Abala Bose, wife of JC Bose

Jagadish Chandra Bose has a permanent place in the world of science, especially in Botany. He began the Age of Modem Science in India and deserves honor for this. He had all the qualities that research requires. He had keen powers of observation and he was patient. He was also a very good lecturer. His students loved his lectures. He did not teach only for the sake of the examination. Students should study books and study what the teacher teaches, but this is not enough; they should use their brains and think for themselves; they should be eager to discover new knowledge – this is what he taught his students. He encouraged them to observe, to experiment and to think, without depending only on books and teachers.

Jagadish Chandra Bose died in November 1937. To the very end, he was busy with research.

Wealth and power never attracted Jagadish Chandra Bose. He toiled for science like a saint, selflessly. This great scientist is a great example to all.
