Life notes
I hadn’t checked my notifications on X.com in a while. When I did yesterday, I found Pradx had tagged me in a blog post called “a challenge of blog questions” in March. The point is to answer a short list of questions about my blogging history, then tag

From ’Sharks hunt via Lévy flights’, Physics World, June 11, 2010: They were menacing enough before, but how would you feel if you knew sharks were employing advanced mathematical concepts in their hunt for the kill? Well, this is the case, according to new research, which has tracked the movement

A heatwave is like the COVID-19 virus. During the pandemic, the virus infected and killed many people. When vaccines became available, the mortality rate dropped even though the virus continued to spread. But vaccines weren’t the only way to keep people from dying. The COVID-19 virus killed more people

In physics, the second law of thermodynamics says that a closed system tends to become more disordered over time. This disorder is captured in an entity called entropy. Many devices, especially clocks, are affected by this law because they need to tick regularly to measure time. But every tick creates

Scientists have made a new material that is both a quasicrystal and antiferromagnetic — a combination never seen before. Quasicrystals are a special kind of solid. Unlike normal crystals, whose atoms are arranged in repeating patterns, quasicrystals have patterns that never exactly repeat but which still have an overall order. While

In the last two or three years, groups of scientists from around the world have made several claims that they had discovered a room-temperature superconductor. Many of these claims concerned high-pressure superconductors — materials that superconduct electricity at room temperature but only if they are placed under extreme pressure (a million

There's no denying that there currently prevails a public culture in India that equates criticism, even well-reasoned, with pooh-poohing. It's especially pronounced in certain geographies where the Bharatiya Janata Party (BJP) enjoys majority support as well as vis-à-vis institutions that the subscribers of Hindu politics consider

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

Featured image: All matter around us is made of elementary particles, the building blocks of matter. These particles occur in two basic types called quarks and leptons. Each group consists of six particles, which are related in pairs, or ‘generations’. The muon is a type of lepton, denoted by the

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
