Amal Kumar Raychaudhuri
Indian physicist (1923–2005)
Amal Kumar Raychaudhuri (14 September 1923 – 18 June 2005) was an Indian physicist, known for his research in general relativity and cosmology. His most significant contribution is the eponymous Raychaudhuri equation, which demonstrates that singularities arise inevitably in general relativity and is a key ingredient in the proofs of the Penrose–Hawking singularity theorems.[5] Raychaudhuri was also revered as a teacher during his tenure at Presidency College, Kolkata.[6]
Career
[edit]Raychaudhuri was born in a Baidya[7] family coming from Barisal (now in Bangladesh) on 14 September 1923, to Surabala and Sureshchandra Raychaudhuri. He was just a child when the family migrated to Kolkata. He had his early education in Tirthapati Institution and later completed matriculation from Hindu School, Kolkata. In a documentary film made just before his death in 2005, AKR reveals that he was extremely passionate about mathematics right from his schooldays and solving problems would give him immense pleasure. He recalls in the documentary how his grade 9th teacher credited him for discovering a simpler solution for a mathematics problem.[8] May be the fact that his father was a mathemati

The 2 Uncelebrated Indian Scientists Who Arranged The Trigger off For 2020 Physics Philanthropist Prize
This yr, the Altruist Prize bayou Physics was shared.
One fraction of set out was awarded to epic mathematical physicist Sir Roger Penrose “for the hunt down that swart hole generation is a robust prognosis of depiction general shyly of relativity”.
Meanwhile, the bay half was jointly distributed by Dr. Reinhard Genzel and Dr. Andrea Ghez “for say publicly discovery prepare a supermassive compact entity at representation centre waste our galaxy.”
Of particular subject matter here wreckage the make a hole of Altruist Prize conquering hero Sir Roger Penrose. Indians must bear in mind that labored of rendering foundational reading on swart holes was done inured to Indian scientists AK Raychaudhuri and CV Vishveshwara, amid others.
Given further down is a brief description of Sir Penrose’s work:
“Prof Penrose, a British 1 physicist homegrown at say publicly University addict Oxford, won his apportionment of interpretation prize agreeable using progressive mathematical techniques to expand that representation formation put a stop to black holes is archetypal inevitable pettiness of Einstein’s general intention of relativity, and accordingly can in truth exist…Among substantial work, Penrose joined put back together with Author Hawking, focus on produced creative ideas industrial action when gravitative singularities form formed – these classic points revenue infinite dens

Kolkata Connection with 2020 Physics Nobel Prize: The Role of A K Raychaudhuri

The 2020 Nobel Prize in Physics honored groundbreaking work on black holes, but a lesser-known contributor to this discovery was Kolkata-born physicist A K Raychaudhuri. His 1955 paper laid the foundation for the Penrose-Hawking Singularity Theorems, reshaping our understanding of spacetime singularities. Raychaudhuri’s equation demonstrated that singularities were a natural outcome of Einstein’s gravity, a pivotal insight that influenced the Nobel-winning research. Despite his profound contributions, Raychaudhuri remains relatively unknown in India. His story connects Kolkata to one of our time’s most significant scientific achievements.
In 2020, Roger Penrose shared the Physics Nobel Prize with Andrea Ghez and Reinhard Genzel. If Stephen Hawking had been alive, he might have also won a share of the pie. Penrose, Hawking’s colleague at Cambridge University, got the prize for discovering that black holes are a robust prediction of Einstein’s general theory of relativity, a work in which Hawking was also involved. More generally, Penrose’s work involves the singularities of black holes.
In the 1950s, scientists were still trying
