Worlds between theory and experiment
Once Isaac Newton showed that a single gravitational law plus his rules of dynamics could reproduce the orbits of planets that Johannes Kepler had predicted, explain tides on Earth, and predict that a…

A gentle reminder before we begin: you're allowed to be interested in particle physics. 😉 Neutrinos are among the most mysterious particles in physics. They are extremely light, electrically neu…
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 co…
This page appeared in The Hindu’s e-paper today. I wrote the lead article, about why scientists are so interested in an elementary particle called the top quark. Long story short: the top quark is th…
My first byline as a professional journalist (a.k.a. my first byline ever) was oddly for a tech story – about the advent of IPv6 internet addresses. I started writing it after 7 pm, had to wrap it up…
At 9 pm India time on April 7, physicists at an American research facility delivered a shot in the arm to efforts to find flaws in a powerful theory that explains how the building blocks of the univer…
In the face of complaints about how so few women have been awarded this year’s Swarnajayanti Fellowships in India, some scientists pushed back asking which of the male laureates who had been selected…
Every July 4, I have occasion to remember two things: the discovery of the Higgs boson, and my first published byline for an article about the discovery of the Higgs boson. I have no trouble believing…
I was randomly rewatching The Big Bang Theory on Netflix today when I spotted this gem: Okay, maybe less a gem and more a shiny stone, but still. The screenshot, taken from the third episode of the s…
A fascinating observation by Cixin Liu in an interview in Public Books, to John Plotz and translated by Pu Wang (numbers added): … technology precedes science. (1) Way before the rise of modern scien…
Say you're in a dark room and there's a flash. The light travels outward in all directions from the source, and the illumination seems to expand in a sphere. This is a visualisation of how the…
One of the more fascinating bits of high-energy physics is the branch of physics called quantum chromodynamics (QCD). Don’t let the big name throw you off: it deals with a bunch of elementary particle…
