Neural network supercharges model’s ability to predict phase transitions
Place a pot of water on the stove and light the fire. Once the temperature in the pot reaches 100º C or so, the water will boil to vapour. This is an example of a phase transition that occurs every … Continue reading

A physics story of infinities, goats and colours
When I was writing in August about physicist Sheldon Glashow’s objection to Abdus Salam being awarded a share of the 1979 physics Nobel Prize, I learnt that it was because Salam had derived a theory that Glashow had derived as well, taking … Continue reading

‘Surface of last screaming’
This has nothing to do with anything in the news. I was reading up about the Big Bang for a blog post when I came across this lucid explanation – so good it’s worth sharing for that reason alone – … Continue reading

A tale of vortices, skyrmions, paths and shapes
There are many types of superconductors. Some of them can be explained by an early theory of superconductivity called Bardeen-Cooper-Schrieffer (BCS) theory. In these materials, vibrations in the atomic lattice force the electrons in the material to overcome their mutual … Continue reading
