R Rajaraman, the Indian physicist recruited by Robert Oppenheimer who always wanted to come home

R Rajaraman, the Indian physicist recruited by Robert Oppenheimer who always wanted to come home

In 1963, a young Indian confronted a dilemma that few in the present generation would have. Ramamurti Rajaraman had just obtained his doctorate from Cornell University, his supervisor being the future Nobel laureate Hans Bethe, who had played a major role in the Manhattan Project. In those days of frenzied armament, Ramamurti, just 24, with a doctorate in nuclear theory, was a prized catch for America. But he wanted to abandon his chosen discipline, return home and devote himself to social service. As his first death anniversary falls on July 12, Rajaraman’s life reflects how much India has changed since then. Born in 1939 in Coimbatore, Rajaraman shifted to Delhi with his parents. His father, Dr B Ramamurti, taught mathematics before he joined the founding team of the Central Statistical Organisation. Around that time, Tamils had begun arriving in Delhi for jobs in British bureaucracy. With command over English, they soon occupied government posts. And then emerged a concern: How to inculcate Tamil education in their children who had been removed from their culture? To …

Problematics | Einstein Bridge | Hindustan Times

Problematics | Einstein Bridge | Hindustan Times

Over the weeks, months and years, Problematics puzzles have gone into various games ranging from cricket and football to cards, dice and Chinese checkers, and occasionally lesser-known games too. One game we have not yet touched, however, is contract bridge. That is because our puzzles belong to a different world from bridge, even though it can be argued that the game’s intricate rules represent a whole puzzle universe in themselves. For representational purposes only. (Shutterstock) One way to bring bridge into Problematics is with an Einstein puzzle. For those who have never played or watched bridge, there is no need to go into the detailed rules for this puzzle. All we need to know is: (a) bridge is played by two teams, North & South (one pair of partners) vs East & West (the opposing pair of partners); (b) a “trick” is a set of four cards, one played by each player on the table; (c) this “playing” is preceded by a stage called “bidding”, in which players in turn call out the number of …

James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus

James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus

James Webb Space Telescope has recently captured a detailed image of an unusual cosmic occurrence. The latest images released by European Space Agency shows a glowing ring in the depths of space. It also reveals an effect that is caused by a massive galaxy bending light from another galaxy hidden behind it. The phenomenon has been recorded in the constellation Hydrus. It has been observed that light from the background galaxy forms a ring due to gravitational bending. Formation of the Einstein Ring According to the European Space Agency and the Canadian Space Agency the sight captured is known as an Einstein ring. It was reported that the effect is caused when a massive object bends light from another galaxy located behind it. The report further highlights that the foreground galaxy shown in the images belongs to a cluster known as SMACSJ0028.2-7537. The light from a distant spiral galaxy is being curved by the gravitational pull of the elliptical galaxy in front. As per the official statement from ESA, the effect is a classic case of …

Scientists discover “Einstein ring” around near-by galaxy: What it is — and its significance | Explained News

Scientists discover “Einstein ring” around near-by galaxy: What it is — and its significance | Explained News

The European Space Agency’s (ESA) Euclid space telescope has discovered a rare ring of light, known as an Einstein ring, around a galaxy nearly 590 million light-years away from Earth. Photos, which were taken by Euclid in September 2023 but released on Monday, of the Einstein ring show a bright ball of light in the centre with a bright, cloudy ring around it. The ring was discovered around NGC 6505, a galaxy that was first found in the 19th Century. Stephen Serjeant, an astronomer at the Open University, told The Guardian, “This is a beautiful, extraordinary, thrilling and lucky find in our first data.” Story continues below this ad What is an Einstein ring? An Einstein ring is a ring of light around a form of dark matter, galaxy or cluster of galaxies. It is essentially an example of gravitational lensing. Gravitational lensing is a phenomenon which occurs when a massive celestial body — such as a galaxy or cluster of galaxies — creates a gravitational field which distorts and amplifies the light from distant …

Euclid Space Telescope Discovers Rare Einstein Ring, Revealing Dark Matter Secrets

Euclid Space Telescope Discovers Rare Einstein Ring, Revealing Dark Matter Secrets

A rare Einstein ring has been detected by the Euclid space telescope, offering valuable insights into dark matter distribution. The phenomenon, created by the gravitational lensing effect of a galaxy located nearly 600 million light-years away, has provided researchers with a means to analyse the mass and composition of the lensing galaxy. The discovery occurred as Euclid commenced its mission to construct an extensive 3D map of the universe. Dark Matter Insights from Gravitational Lensing According to research published in Astronomy & Astrophysics, the gravitational lens responsible for this Einstein ring has been identified as the galaxy NGC 6505. Situated around 590 million light-years from Earth, the galaxy’s mass is significant enough to bend light from a more distant source, forming a nearly perfect circle. This alignment has enabled scientists to examine the lensing galaxy’s central region, where dark matter presence is notably lower than expected. As reported by space.com, the research team has referred to this structure as “Altieri’s lens,” named after astronomer Bruno Altieri, who played a key role in its identification. The …

Einstein’s Theory of Relativity Passes Its Biggest Test After Observations From Dark Energy Spectroscopic Instrument

Einstein’s Theory of Relativity Passes Its Biggest Test After Observations From Dark Energy Spectroscopic Instrument

In a new study published on Tuesday, researchers from the Dark Energy Spectroscopic Instrument (DESI) project suggest that the mysterious force known as dark energy might not remain constant over time, challenging existing assumptions in cosmology. While the findings hint that dark energy, believed to drive the universe’s accelerated expansion, may be waning, the study simultaneously upholds the validity of general relativity, Albert Einstein’s foundational theory of gravity. Published on the DESI project’s website and on arXiv, the study builds on an April report from the same collaboration that had indicated a similar outcome. DESI’s Expansive Galaxy Mapping Efforts The DESI project, conducted at the Kitt Peak National Observatory in Arizona, has created an unprecedented 3-D map of galaxies, which allows scientists to explore the structure and growth of cosmic formations over time. Unlike previous analyses, which primarily examined baryon acoustic oscillations — sound waves from the early universe that are still detectable — the latest study includes data on how galaxy formations evolve. Cosmologist Dr Dragan Huterer of the University of Michigan noted that …

Who’s Playing Albert Einstein? When And Where To Watch The Docufilm?

Einstein And The Bomb Documentary ( Photo Credit – Netflix ) Trust Netflix when it comes to releasing documentaries that will startle everyone. Earlier, the platform released Lover, Stalker, Killer, which got everyone talking about the twisted love and crime documentary. The latest one that has blown everyone’s mind is Einstein and the Bomb. The documentary film has used archival footage of the renowned physicist and presented the narrative with dramatic recreation. In this article, we will tell you everything you need to know about the docufilm. Einstein and the Bomb Plot/Synopsis The official synopsis reads, “What happened after Einstein fled Nazi Germany? Using archival footage and his own words, this docudrama dives into the mind of a tortured genius.” The events in the documentary take place in 1933, years before the atomic bomb was dropped on Japan’s Hiroshima. Simply put, all of this happened between the events in Christopher Nolan’s Oppenheimer movie. Albert Einstein was in Germany and about to get prosecuted during this time. The Nazis would do anything to assassinate him. However, …
