HOMI BHABHA

My success will not depend on what A or B thinks of me.
My success will be what I make of my work.
               On April 20, 1944, Bhabha in a letter to Subrahmanyan Chandrasekhar (1910-95) wrote: "...I have recently come to the view that provided proper appreciation and financial support are forthcoming, 'it was one's duty to stay in one's country and build up schools comparable with those that other countries are fortunate in possessing."
           And we know now that he is the person behind the establishment of the two great research centers in the country,Tata Institute of Fundamental Research (TIFR), and the Atomic Energy Establishment at Trombay (which after Bhabha's death was renamed as the Bhabha Atomic Research Centre (BARC).
           

            He was born on 30th of october in 1909 at Mumbai.During the time of his education his father and uncle wanted him to become an engineer. If it so happened according to their wish, India might have lost a great personality...
     In 1928 Bhabha in a letter to his father wrote: "I seriously say to you that business or job as an engineer is not the thing for me. It is totally foreign to my nature and radically opposed to my temperament and opinions. Physics is my line. I know I shall do great things here. For, each man can do best and excel in only that thing of which he is passionately fond, in which he believes, as I do, that he has the ability to do it, that he is in fact born and destined to do it... I am burning with a desire to do physics. I will and must do it sometime. It is my only ambition. I have no desire to be a `successful' man or the head of a big firm. There are intelligent people who like that and let them do it... It is no use saying to Beethoven `You must be a scientist for it is great thing ' when he did not care two hoots for science; or to Socrates `Be an engineer; it is work of intelligent man'. It is not in the nature of things. I therefore earnestly implore you to let me do physics." 
          His father accepted but first after completion of his engineering studies.

And he made many significant contributions in his field.Some of them are
The explanation of relativistic exchange scattering (Bhabha Scattering).
The theory of production of electron and positron showers in cosmic rays (Bhabha-Heitler theory).
Speculation about the Yukawa particle related to which was his suggestion of the name meson.
Prediction of relativistic time dilatation effects in the decay of the meson.

         

            In 1939 he came back to India during world war.After spending a few years in India Bhabha was no longer interested in going back to England.
        He realised that there was no institute in the country which had the necessary facilities for original work in nuclear physics, cosmic rays, high energy physics, and other frontiers of knowledge in physics.
 This prompted him to send a proposal in March 1944 to the Sir Dorab J. Tata Trust for establishing 'a vigorous school of research in fundamental physics'. In his proposal he wrote : "There is at the moment in India no big school of research in the fundamental problems of physics, both theoretical and experimental. There are, however, scattered all over India competent workers who are not doing as good work as they would do if brought together in one place under proper direction. It is absolutely in the interest of India to have a vigorous school of research in fundamental physics, for such a school forms the spearhead of research not only in less advanced branches of physics but also in problems of immediate practical application in industry. If much of the applied research done in India today is disappointing or of very inferior quality it is entirely due to the absence of sufficient number of outstanding pure research workers who would set the standard of good research and act on the directing boards in an advisory capacity ... Moreover, when nuclear energy has been successfully applied for power production in say a couple of decades from now, India will not have to look abroad for its experts but will find them ready at hand. I do not think that anyone acquainted with scientific development in other countries would deny the need in India for such a school as I propose."
          Finally it came into existance as TIFR.



          Years before India became an independent nation, Bhabha was already in command of India's nuclear future.

       

Ramanna confirms that Bhabha planned from the very outset to establish an Indian nuclear weapons capability. Bhabha told Ramanna during that period that
   "We must have the capability.We should first prove ourselves and then talk of  Gandhi, non-violence and a world without nuclear weapons."
         On April 26, 1948 Bhabha sent a note entitled 'Organisation of Atomic Research in India' to the then Prime Minister of India, Jawaharlal Nehru. In this note Bhabha wrote: "The development of atomic energy should be entrusted to a very small and high powered body composed of say, three people with executive power, and answerable directly to the Prime Minister without any intervening link. For brevity, this body may be referred as the Atomic Energy Commission". Bhabha emphasised that the proposed Atomic Energy Commission should have "its own secretariat independent of the secretariat of any other ministry or department of the government, including the envisaged Department of Scientific and Industrial Research". He also suggested that once the Commission was appointed the existing Board of Research on Atomic Energy should be abolished. The Government of India accepted Bhabha's proposal within a few months after its submission and with the promulgation of the Indian Atomic Energy Act 1948, the Atomic Energy Commission was formed in August 1948 .

                      
 He is not only a person of science but considered as a complete person.He once said  "I cannot increase the content of life by increasing its duration, I will increase it by increasing its intensity. Art, music, poetry and everything else … I do have this one purpose — increasing the intensity of my consciousness of life.



                                           In his tribute paid to Bhabha, Lord Redcliffe-Maud has aptly described the different facets of Bhabha's personality: "Affectionate and sensitive, elegant and humorous, dynamic and now dead. Homi was one of the very few people I have ever known (Maynard Keynes was another) who enhance life whatever the context of their living. In Homi's case this was because he was fantastically talented but so fastidious about standards that he was never a dilettante. Whatever he set himself to do, he did as a professional- but one who worked for love. He was relentlessly creative, enhancing life because he loved all forms of it. So he became a living proof that scientific excellence can go with excellence in arts and racial differences need be no bar to friendship. When Indian Art was last exhibited in London, the one picture chosen for reproduction on the poster outside Burlington House was one of Homi's. He was as fond of music as he was of pictures, contriving to fly in from India as the first Edinburgh Festival began and, when the question of a late Beethoven quartet was raised in conversation, knowing the opus number. At one UNESCO conference after another he stood out even among the other distinguished members of the Indian delegation, as a world citizen qualified in all three subjects - education, science and culture - as hardly another member of the conference was. He was in fact an obvious choice for the headship of the Organization if he had felt inclined that way. Those qualified must judge how grievous was his death for India and for science and for civilization".

JATINDRA NATH DAS

A post from on 13th september 2011 read like this:
"In this season of fasts,does any one remember Jatin Das?"




Balbir K. Punj wrote "On September 13, 1929, a youth from Bengal gave up his life in a prison of Lahore fasting for 63 days. He literally fasted unto death in Gandhian fashion though Mahatma Gandhi himself never touched that apogee despite undertaking 17 fasts unto death in his lifetime.
…does any Congressman remember Jatindra Nath Das (1904-1929), who adopted the Gandhian instrument of fast unto death and adhered to it steadfastly unto his last? Of millions in the country who swore by Gandhism, Jatin Das alone walked till the end of path."
                                        



He is the only person in INDIA to fast unto death before the INDIAN Independence.

In November 1925, while studying for a B.A. at Vidyasagar College in Calcutta, Jatindra Nath was arrested for his political activities and was imprisoned at the Mymensingh Central Jail. While being interned there, he went on a hunger strike to protest the ill-treatment meted out to the political prisoners. After fasting for 20 days, the Jail Superintendent apologised and he gave up the fast. He was contacted by revolutionaries in other parts of India and agreed to participate in bomb-making for Bhagat Singh and comrades.


On 14 June 1929 he was arrested for revolutionary activities and was imprisoned in Lahore jail to be tried under the supplementary Lahore Conspiracy Case. In the Lahore jail, Jatin Das started a hunger strike along with other revolutionary fighters, demanding equality for Indian prisoners and undertrials. The conditions of Indian inhabitants of the jails was deplorable-the jail uniforms that they were provided with were not washed since several days, the kitchen area and the food was covered with rats and cockroaches, they were not provided with any reading material-no newspapers, no paper, while the condition of the English prisoners in the same jail was strikingly different. The memorable hunger strike started on 13 July 1929 and lasted 63 days.The jail authority took many measures to forcibly feed Jatin Das and the other freedom fighters, beat them and did not even provide them with drinking water. However, Jatindra did not eat. The jail committee recommended his unconditional release, but the government rejected the suggestion and offered to release him on bail. Jatin died on September 13, 1929, after his unbroken hunger strike for 63 days. Durga Bhabhi led the funeral procession of Jatin Das from Lahore to Kolkata. As his body was carried from Lahore to Kolkata by train, thousands of people rushed to every station to pay their homage to the martyr. A two-mile long procession in Kolkata carried the coffin to the cremation ground. The hunger strike of Jatin Das in prison was one crucial moment in the resistance against illegal detentions. After his death, the Viceroy informed London: ‘Jatin Das of the Conspiracy Case, who was on hunger strike, died this afternoon at 1 p.m. Last night, five of the hunger strikers gave up their hunger strike. So there are only Bhagat Singh and Dutt who are on strike .’


SUBASH CHANDRA BOSE chronicled, "As the days rolled by, one by one the hunger-strikers dropped off, but young Jatin was invincible. He never hesitated, never faltered for one small second but marched straight on towards death and freedom. Every heart in the country melted but the heart of the bureaucracy did not. So Jatin died on September 13th. But he died a martyr's death. After his supreme sacrifice, the whole country gave him an ovation which few men in our recent history have received. As his body was removed from Lahore to Calcutta for cremation, people assembled in their thousands and tens of thousands at every station to pay their homage".


The highest tributes were paid by almost every leader in the country. Mohammad Alam and Gopi Chand Bhargava resigned from the Punjab Legislative Council in protest. Motilal Nehru proposed the adjournment of the Central Assembly as a censure against the inhumanity of the Lahore prisoners. The censure motion was carried by 55 votes against 47.

 "Another name has been added to the long and splendid roll of INDIAN martyrs.Let us bow our heads and pray for strength to act to carry on the struggle, however long it may be and whatever consequences , till the victory is ours."This is what Jawahar Lal Nehru said while commenting on death of Jatin Das.

MISSILE MAN OF INDIA.

He is among the persons who lifted the glory of our country.
A.P.J. Abdul Kalam worked very hard when there was total loss of belief.He proved that we could indigenously build our own Launch vehicles and Missiles. A man of inspiration to all of us.
Do not look at Agni as an entity directed upward
to deter the ominous or exhibit your might.
It is fire
in the heart of an Indian. Do not even give it
the form of a missile
as it clings to the
burning pride of this nation
and thus is bright.
