From ‘What is next for Iran’s nuclear programme?’, The Hindu, June 28, 2025: As things stand, Iran has amassed both the technical knowhow and the materials required to make a nuclear weapon. Second, the Israelis and the Americans have failed to deprive Iran of these resources in their latest
'Quasi' means almost. It's an unfair name for quasicrystals. These crystals exist in their own right. Their name comes from the internal arrangement of their atoms. A crystal is made up of a repeating group of some atoms arranged in a fixed way. The smallest arrangement
A particle collider is a machine that energises two beams of subatomic particles and smashes them head on. The Large Hadron Collider (LHC) in Europe is the world's largest and most famous particle collider. It accelerates (with the effect of energising) two beams of protons to nearly the
In his latest newsletter, Bruce Schneier springboarded off of articles in Washington Post and The Atlantic to write: There’s a balance between the cost of the thing, and the cost to destroy the thing, and that balance is changing dramatically. This isn’t new, of course. Here’s an
Engineering as a methodology … contains a fundamentally materialist kernel, even if its present incarnation as a bourgeois science drives engineers to think and behave otherwise. — Nick Chavez, Engineers, Materialism, and the Communist Method After school, I studied mechanical engineering against my will. Most engineering students at the time did, and
NASA/SpaceX/Axiom will make their next attempt to launch the Axiom-4 mission to the International Space Station on June 11. Axiom Space’s tagline for the mission is “Realizing the Return”, alluding to three of the mission’s four crew members, including India’s Shubhanshu Shukla, will be taking
If the government has taken its hand off the wheel, it needn't be a bad thing that Rapido is helping auto drivers opt for more rational fares instead
If a state isn't swayed by public opinion and threatens violence against dissidents, is it worth reconsidering what sanctioning non-combatants can be expected to achieve?
From ‘Meghalaya’s new cave-dwelling fish adapts to streams overground’, The Hindu, May 25, 2025: An underground cave in Meghalaya, in focus for a conflict over a Shivalinga-like stone formation, has yielded a new-to-science fish that adapts to streams overground. A team of zoologists, led by Kangkan Sarma of Gauhati
There’s a concept in quantum mechanics, and also in parts of classical mechanics, called the Berry phase. Say you’re walking around a mountain. You start off along a path and follow it all the way until you’re back to the point where you started. You’re at
Every once in a while, I dive into a topic in science for no reason other than that I find it interesting. This is how I learnt about Titan, laser-cooling, and random walks. This post is about the fourth topic in this series: solitons. A soliton is a stable wave
There was an intriguing outpouring of concern worldwide when Sunita Williams and Barry Wilmore returned to Earth after 280-something days in space. People were particularly concerned about Williams’s health and how she was doing, as if Wilmore hadn’t been there with her living through the same mission. Researchers

The maximum daytime temperatures in the Kalaburagi and Belagavi districts of Karnataka this week are expected to be 41º C and in the late 30sº C, respectively. Research has found that if the relative humidity is high enough to render a wet-bulb temperature exceeding 30º C, outdoor exposure of even

From '‘The physics community has never split like this’: row erupts over plans for new Large Hadron Collider', The Guardian, March 29, 2025: However, if the FCC were given the go-ahead, it could lock up funds for decades and end up dictating the direction that particle physics will

I recently started reading a book entitled The Lions of Al-Rassan by Guy Gavriel Kay. It is historical fiction, immaculately detailed, with three excellent protagonists surrounded by a band of almost as admirable allies navigating a middle-era Spain in which three powerful politico-religious factions are vying for greater power. The

A day before NASA astronauts Sunita Williams and Barry Wilmore were to return onboard a SpaceX crew capsule, Prime Minister Narendra Modi published a letter in which he said he had inquired after her when he met U.S. President Donald Trump and that even if “you are thousands of

An odd little detail in a Physics World piece on Microsoft’s claim to have made a working topological qubit: Regardless of the debate about the results and how they have been announced, researchers are supportive of the efforts at Microsoft to produce a topological quantum computer. “As a scientist

After US troops withdrew from Afghanistan after two decades in 2021, the Taliban returned to power. In its oppressive regime many groups of people, but especially women, girls, and minorities, have lost most of their civil rights. In this time, Afghanistan has also suffered devastating floods and an ongoing famine,

While I have many issues with how the Nobel Prizes are put together as an institution, the scientific achievements they have revealed have been some of the funnest concepts I’ve discovered in science, including the clever ways in which scientists revealed them. If I had to rank them on

Finally some external validation. After months of insisting Sunita Williams and Barry Wilmore aren’t “stuck” or “stranded” in the International Space Station, after Boeing Starliner’s first crewed flight test went awry, the two astronauts have themselves repudiated the use of such words to describe their mission profile so
