In 2018, scientists from IISc announced they'd found a room-temperature superconductor, an exotic material that has zero resistance to electric current in ambient conditions – considered the holy grail of materials science. But in the little data the authors were willing to share with the world, something seemed off.

I have an undergraduate degree in mechanical engineering but I've always struggled with thermodynamics. To the uninitiated, this means most of the knowledge specific to mechanical engineering over other branches remains out of my reach. I would struggle even with the simpler concepts, and perhaps one of the

In 1907, a New Zealander named Ernest Rutherford moved from McGill University in Canada to the University of Manchester. There, he conducted a series of experiments where he fired alpha particles1at different materials. When he found that the beams deviated by about 2º when fired through air, he figured that

The following tweet has been doing the rounds the last few days: https://twitter.com/churumuri/status/1062680702066388992 It carries an important message from India's recent past, that a time of free-as-in-free speech actually did exist only half a century ago. It stands in stark contrast to the

Alanna Mitchell reports in the New York Times that boreal forests in the world's north are being invaded by worms of the species Dendrobaena octaedra. They're decomposing the leaf litter and releasing carbon dioxide into the atmosphere, transforming these carbon-negative forests into carbon-positives. In the process,

You probably haven't heard of the Chladni effect but you've likely seen it in action. Sprinkle some grains of sand on a thin metal plate and play a violin bow across it, and you'll notice that the grains bounce around for a bit before

This post was originally published on October 6, 2012. I recently rediscovered it and decided to republish it with a few updates. Geometric symmetry in nature is often a sign of unperturbedness, as if nothing has interfered with a natural process and that its effects at each step are simply

I saw this tweet yesterday: Information like this always reminds me of one fact that awakened me to the behind-the-scenes role that the natural universe plays in our cultural lives. The organic compounds called indole and skatole are what give human poop its unique and uniquely disgusting smell – an odour

My piece on May 12 calling out Prime Minister Narendra Modi's baffling conviction in his knowledgeability about surveillance radar systems and atmospheric attenuation has prompted some criticism as to its scientific accuracy. Apart from the compulsively defensive bhakts, some scientists also wrote to me saying that Modi was

I am not a person jo saare vigyan ko jaanta ho – lekin maine kaha itne cloud hain, baarish ho rahi hai ki ek benefit hain ki hum radar se bach sakte hain. This is Prime Minister Narendra Modi. Translated to the English: I am not a person who knows knows

The debate about whether it is fair for scientists to expect science journalists to let them proofread articles in which they are quoted before going to print has reared its head once more, at least on Twitter, following one round of exchanges last year. The central animus is the same:
