#TodayInHistory Homi Jehangir Bhabha, the father of India’s nuclear program, founder of TIFR and Atomic Energy Establishment at Trombay, one of the most brilliant minds ever, dies in a rather mysterious plane crash in 1966.

He was born into a well to do family in Mumbai on October 30,1909 to Jehangir Hormusji Bhabha, a prominent Parsi lawyer, and Meheren. He was related to prominent Parsi businessmen like Dinshaw Petit and Dorabji Tata.
He attended Royal Institute of Science in 1927, and his uncle Dorabji wanted him to do engineering so that he could join Tata Group. However his main interest was physics, and he had no desired for Engineering. #homijehangirbhabha
I am burning with a desire to physics. …. It is my only ambition. I have no desire to be a “successful” man or the head of a big firm.” #homijehangirbhabha
And his parents agreed to his wish and sent him to Cambridge.
Bhabha’s father understanding his son’s desires, agreed to fund his higher studies in Science, provided he passed the Tripos exam in Mechanical Sciences. Bhabha passed with first class in June 1930, and he later did his Mathematical Tripos under noted physicist Paul Dirac.
Around the same time he also began to work at the Cavendish Laboratory, which was the center for a number of significant breakthroughs in science. Be it James Chadwick’s discovery of the Neutron or John Cockroft, Ernest Walton splitting the atomic nucleus.
Around this time nuclear physics was gaining importance, attracting some of the best minds, primarily due to the fact that unlike conventional physics, there was much larger scope for experimentation here.
He had a lifelong passion for conducting experiments on radiation emitting particles and in 1933 he received the doctorate in nuclear physics, after publishing his first ever scientific paper “The Absorption of Cosmic radiation“. #homijehangirbhabha
Dealing with electron shower production in cosmic rays, he won the Newton Studentship in 1934 for the paper. He balanced time between Cambridge and working with the noted physicist Niels Bohr. #homijehangirbhabha
He also co authored a paper “The Passage of Fast Electrons and the Theory of Cosmic Showers” along with Walter Heitler in 1936, which described how primary cosmic rays from outer space interact with the upper atmosphere to produce particles observed at the ground level.
When World War II broke out in 1939, Bhabha who was in India then decided to stay back, and accepted an offer to serve as reader in Physics Dept of then newly founded IISC.
He set up a Cosmic Ray Research Institute there with the funding he got from Dorab’s trust, and he would later set set up the TIFR(Tata Institute of Fundamental Research) with ample support from JRD Tata. #homijehangirbhabha
Bhabha was the first director of TIFR, and after independence he played a role in setting up the Atomic Energy Comission, in 1948, also served as it’s first chairman. Nehru also gave Bhabha the responsibility of heading India’s nuclear program.
He literally built India’s nuclear program from scratch, considering there was no infra to do research in nuclear physics, cosmic rays when he started out. #homijehangirbhabha
TIFR was the outcome of his dreams, as he raised the funds for it and then built it all the way with support from JRD.
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. #homibhabha
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. #homibhabha
More than anything he was the visionary behind India’s 3 point Nuclear Program. In sharp contrast to other nations that used uranium for nuclear energy, Bhabha focused more on India’s extensive thorium reserves, which made more sense, as importing uranium would have been costly.
#homibhabha 's 3 stage program
Stage 1
First generation of Atomic power plants using natural uranium fueled pressurized Heavy Water Reactors to generate power, while generating Plutonium-239 as a by product. Most of the base of India’s existing nuclear power is first stage.
Stage 2
Plutonium 239 generated in Stage 1, would be used as fuel for Fast Breeder Reactors , which in turn would generate more fuel during fission process. The proposed Prototype FBR at Kalpakkam was in Stage 2, but delayed due to many reasons. #homijehangirbhabha
He gained fame deriving a correct expression for the probability of scattering positrons by electrons, which gave rise to the Bhabha Scattering in quantum electrodynamics. He also played a pivotal role in guiding Vikram Sarabhai in setting up ISRO. #homijehangirbhabha
January 24, 1966
The flight on which he was travelling to Vienna crashed on Mont Blanc, a terrible tragedy. The father of India’s nuclear program, Homi Jehangir Bhabha was no more. A brilliant career and life cut short.
There is speculation that Homi Bhabha could have been the victim of a CIA plot, with the US wary of India’s growing nuclear power, especially after the defeat of it’s ally Pakistan in the ’65 War. This was stated by ex CIA operative Bob Crowley in an interview.
Conversations with Crow, book on a series of telephonic talks and interviews between ex CIA operative Bob Crowley and journalist Gregory Douglas, has the former stating that the CIA had a hand in the plane crash that killed Bhabha, remains a mystery to date. #homibhabha
Atomic Energy Establishment at Trombay has been named in honor of Bhabha as BARC, The famous radio telescope at Ooty was another of Bhabha’s initiative, that went operational after his death. #homijehangirbhabha
His sprawling bungalow Mehrangir named after his mother, was given to NCPA, which unfortunately was demolished by the Godrej Family in 2016 who had bought it in 2014.
Homi Jehangir Bhabha one of the great Indian scientists of the modern era, father of India's nuclear program, whose life unfortunately was cut short, in a rather mysterious plane crash on this date in 1966. #LestWeForget

Krantiveera Sangoli Rayanna
Born-August 15, 1798
Died- January 26, 1831
A great revolutionary not known outside of Karnataka, but whose story we should all be knowing. #RepublicDay2022 Image
Sangoli Rayanna,was the loyal general of Kittur Rani Chenamma, who fought by her side in her resistance to the British rule. Even after Kittur fell, and the Rani was captured, he still continued his struggle against the British before he was finally captured and executed.
Kittur is located in the district of Belgavi, in Northern Karnataka. The town would however earn a place in Indian history for the resistance against the East India Company by Rani Chenamma in 1824 when the British threatened to annex her kingdom over the Doctrine of Lapse. Image

#TodayIdHistory The Battle of the Bulge ends in 1945, as the Allies overcome an intense German offensive in the Ardennes, to stop the Allied use of Antwerp, and split the Allied lines, enabling them to be encircled. ImageImageImageImage
It was one of the largest German attacks on the Western front, with over 410,000 men, 1,400 tanks, 2600 artillery and 1000 combat aircraft. And they also lost close to 98,000 men in what was one of the bloodiest battles of the War.
The Allies too suffered great casualties, with the Americans losing around 89,000, making it one of the bloodiest battle ever fought by US in the War, and the 3rd deadliest one after Normandy and Meuse–Argonne offensive in WW1.

For starters #Netaji was no big admirers of either Hitler or the Nazis. It was the Soviet Union whose support he had sought, but Hitler's invasion of Russia and the War between them completely spoilt his plans. Allying with Hitler was a last option for Netaji.
In fact Hitler did nothing to support #Netaji and that is why he made that long trip by U-Boat to Japan. Regarding Japan as an ally, there were a whole lot of reasons, one was it's support for India's independence, and giving shelter to many Indian freedom fighters in exile.
Rash Behari Bose ,was the one who laid the foundation for the INA, building it up, and this was possible only with active Japanese support and the refuge it offered him. So #Netaji allying with Japan was pretty natural, with Russia part of the Allies during the War.

Veer Surendra Sai, who led a long tribal revolt against the British rule in Sambalpur, harassing them to no end. Born on the same date as #NetajiSubhasChandraBose , thread on a rather not so well known freedom fighter.
A born rebel, #veersurendrasai , hailed from the small village of Khinda, and was a Rajput belonging to the Chauhan clan of Khinda-Rajpur. His father Dharam Singh, was a descendant of Aniruddha Sai, the fourth Chauhan ruler of Sambalpur.
When Maharaja Sai passed away in 1827 AD, Surendra Sai presented his legitimate claim to the throne of Sambalpur, as the Maharaja had no male heir.The British however found him too much of an independent thinker for their own good. #veersurendrasai

Rash Behari Bose, founder of INA, mentor to Netaji. a brilliant revolutionary, entrepreneur who set up the first Indian restaurant in Japan, the brains behind the entire INA movement.
Thread on his death anniversary today
There is a whole lot to Rash Behari Bose, one of the masterminds behind the plan to assassinate Lord Hardinge, the Viceroy, a key mover in the Ghadr conspiracy, meant to weaken the British army from inside, a master of disguise, camouflage and the founder of the INA
In many ways Rash Behari was the opposite of his more famed namesake, Subash Chandra Bose. Netaji was a brilliant orator, charismatic leader, who cud sway the masses. Rash Behari on the other hand was more subdued, the brains behind the scene, a strategist.

#TodayInHistory John F Kennedy is sworn in as the youngest President of the US in 1961, and also the only Catholic to date. His inauguration would be marked by the attendane of around 150 scientists, writers, scholars including likes of Ernest Hemmingway.
It was in his inaugural address that JFK uttered the by now famous lines.
Ask not what your country can do for you—ask what you can do for your country.
The inaugural address had both the former Presidents Truman, Eisenhower, as well as future Presidents Nixon, Johnson, Ford making it one distinguished gathering ever.
