Spoiler: I caught my planeSomething has gone a bit wrong with the Deutsche Bahn (DB). Of the last six trains I have tried to take, two were cancelled and three were delayed, including the one I am currently on. On the other hand, my train from Paddington to Swindon on Monday was just fine. I am aware this isn't exactly five sigma, but if your hypothesis was anything to do with "German efficiency" and "crap British trains", there is tension in the data.The tension is somewhat relieved by the

This week on the Physics Central Podcast I'm talking about cheetahs, which have long been admired as the fastest land animals on Earth. But new research shows that speed isn't the big cat's secret to great hunting; it's acceleration. What's the difference? For that we turn to physics! Listen to the podcast to learn more. There's videos too! Just look below the fold.
The new research on cheetah movements was done by scientists at the Royal Veterinary College at the University of London.

Dopo aver letto il riassunto della storiella che vi vado a scrivere qui sotto sulle pagine di Straniero in terra straniera di Robert Heinlein dovevo inevitabilmente andare a verificare. E questo è quello che ho trovato:
Non si erano ancora coricati, quand'ecco gli uomini della città, cioè gli abitanti di Sòdoma, si affollarono intorno alla casa, giovani e vecchi, tutto il popolo al completo.
Chiamarono Lot e gli dissero: "Dove sono quegli uomini che sono entrati da te questa notte? Falli

One of the most enduring and captivating images from our exploration of space in the late 20th century was Voyager 1′s mosaic of our own solar system – a family portrait from 3.7 billion miles away. Captured in these shots was a faint speck of bluish light, in one single pixel of Voyager’s digital camera, [...]

Industrial palladium-copper catalysts change their structures before they get to work, already during the activation process. As a result, the reaction is catalysed by a catalyst that is different from the one originally prepared for it.

The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits.

In terms of weight and size, batteries have become one of the limiting factors in the continuous process of developing smaller and higher performance electronic devices. To meet the demand for batteries having higher energy density and improved cycle characteristics, researchers have been making tremendous efforts to develop new electrode materials or design new structures of electrode materials. Researchers have now investigated the atomistic nature of the lithiation mechanism in individual […]

It’s Plane To See … Joe runs a popular blog with lots of neat stuff, but I have to pick a nit here. Well, honestly I think it’s more than a nit. When something spins while being tethered in place by gravity, its mass wants to fly outward into a pizza-like shape, like frosting flying [...]

Hello and welcome to my personal blog. I’m a science reporter and blogger at The Hindu, an Indian national daily. I’m interested in high-energy physics, the history and philosophy of science, and photography. When no one’s looking, I fiddle with code and call myself a programmer. I enjoy working with the infrastructure that props up […]
