He was more comfortable in French than in German. However, he ended up in staying about a year in Paris. I came out thinking that perhaps after a few weeks in Paris I should be able to go to Berlin to see Einstein. However two things happened: i Friends ii Letter of introduction to Langevin. My friends, who received me on arrival there, took me to their boarding house, where they were staying. Then they all insisted that I should stay there. Well I found it convenient to be among friends.
After reaching Paris he wrote to Einstein requesting his permission to work with him and also for his opinion on his second paper.
I just saw it in print before I left India. I am rather anxious to know your opinion about it, as I think it to be rather important. I have been granted leave by my university for 2 years. I have arrived just a week ago in Paris. I am glad that I shall have the opportunity soon of making your personal acquaintance.
Your papers have already appeared sometime ago. Unfortunately the reprints have been sent to me instead of you. You may have them at any time. I am not in agreement with your basic principle concerning the probability of interaction between radiation and matter, and have given the reasons in a remark which has appeared together with your paper…We may discuss this together in detail when you come here.
However, he started thinking deeply about the objections raised by Einstein. In fact Bose had shown the manuscript to Paul Langevin in Paris, who thought it worth publishing. However, the paper was never published.
Bose wanted to familarise himself with latest developments in theoretical as well as experimental physics. Accordingly Bose thought that he should learn radioactivity techniques from Marie Curie and something of X-ray spectroscopy from Maurice de Broglie Accordingly Bose met Curie. This was because of earlier unhappy experience with an Indian student, who had no knowledge in French. So she had given Bose a long lecture emphasising the importance of knowing French.
Though Bose had a good working knowledge in French but he did not tell the same to Curie at their first meeting. If he informed Curie about his knowledge of French she would have accepted him as her research assistant. Throughout his life Bose never tried to draw attention to himself.
For example William A. Presumably Madame Curie would have accepted him as research assistant had he been able to convince her that he knew sufficient French. Yet he was either too polite or too frightened to interrupt he English monologue by replying in French and thus perhaps convincing her. With a letter of introduction from Langevin, Bose met Broglie, who readily allowed Bose to work with his chief assistant, Alexander Dauvillier. In October that is after spending about a year, Bose proceeded to Berlin.
He was anxious to meet Einstein. But he had to wait several weeks before he could meet Einstein, who was on his annual visit to Leyden. Bose did not work with Einstein but his meeting with him was quite profitable. In the latter half of Bose returned to Dhaka. Though he stayed nearly two years in Europe Bose did not publish anything. His friends suggested that he should apply for the post of Professor in the Physics Department of the Dacca University. They also suggested that he should get a letter of recommendation from Einstein.
Einstein was little surprised at the request because he thought Bose should naturally get the appointment. But he complied with the request. The post was offered to D.
However, when D. Bose declined the offer Bose was appointed as Professor and Head of the Department of Physics in At Dhaka he got engaged in experimental physics. He initiated studies on crystal structures. Perhaps such studies were undertaken for the first time in the country. He took up the task of designing his own experimental equipment. He designed and constructed X-ray diffraction cameras for rotation and powder photography.
He formulated a simple method for identifying the indices of the plane of reflection of Laue photographs recorded in cylindrical camera. He had a fascination for chemistry. So he started doing research in organic chemistry. He studied the reactions of p-acetyle-amino-benzene-sulphonazide with pyridine and he also worked on the synthesis of some r-pyrone derivatives related to Patulin.
In his chemistry related work he was assisted by P. In Bose investigated the problem of total reflection of radio waves in the ionosphere. It is said that it was M. Saha who induced Bose to look into this problem. Saha had once come to Dacca from Allahabad. He gave a lecture in the Physics Department. He addressed a huge gathering at the Curzon Hall. Saha spoke these problems relating to reflection of radio waves from the ionosphere on which he was working.
He asked his friend Bose to work out a solution for an intricate problem like this. Appleton had given three conditions for the reflection of radio waves, Saha introduced a fourth one based on the hypotheses that there is no absorption of radio waves in the ionosphere.
But Saha knew himself that the assumption was arbitrary. So he requested Prof. Bose in the open meeting to give a general solution to the reflection problem. After this lecture Satyendranath concentrated on the problem and finally succeeded in finding a general solution.
During Bose published five important papers on the Unified Field Theory. Although these papers were quite important but they did not create a great stir as earlier papers in He sent these papers to Einstein.
Bose wrote down his reply in detail and he was supposed to discuss it personally with Einstein at Bonn on the occasion of the celebration of the 50th anniversary of the discovery of the theory of relativity. It did not happen. Einstein died in When Bose came to know the death of his master as Bose addressed Einstein in his letters to Einstein he was so overwhelmed with grief that he tore and threw away the only copy of his important paper. And that was the end of his work on the unified field theory,.
He also tried to synthesise emetine and quinine but was forestalled by other foreign scientists. He initiated a systematic search for germanium in Indian sulphide minerals.
A large number of samples of clays, shale and soil from different parts of India were studied. X-ray diffraction methods and the differential thermal analysis were employed in order to understand the atomic structure of common clay minerals and the effect of the layer thickness upon cation exchange.
Since clays are poor reflectors of X-rays, there is a tendency to choose small diameter cameras but in general with small cameras important details of the power diagram may not be resolved. As such, an adjustable flat-plate camera was designed and used in this investigation. The differential thermal analyzer used in the present investigation was constructed after the design of Berkelheimer. Very little work was done in India at the time when this project was undertaken.
As clays were formed under widely varying environmental conditions the study of minerals from regions still unexplored is important both for the purpose of verification and for new information.
With this object in view a differential thermal analyzer and a micro-focus X-ray tube were designed at the laboratory for the study of a number of Indian clays obtained from a wide variety of sources and isolated from different types of soils.
Bose was to start teaching of science. He was also to initiate scientific research in the newly created University. However, Bose was not welcomed by the old-timers at Shantiniketan. In , he was awarded the Padma Vibhushan for his contributions to the sciences and became Fellow of the Royal Society four years later. He was also appointed as the vice-chancellor of Visva-Bharati University. Boson, a class of elementary subatomic particles, was named after Bose to commemorate his contributions to physics.
He was also proficient in knowing poetry such as the works of Lord Tennyson, Rabindranath Tagore and Kalidasa. Share Via. By HT Correspondent. Personal life In , Bose married Ushabala Ghosh who was then 11 years old.
