Dispelling Maxwell’s demon
Maxwell’s demon is one of the most famous thought experiments in the history of physics, a puzzle first posed in the 1860s that continues to shape scientific debates to this day. I’ve struggled to make sense of it for years. … Continue reading

The Hyperion dispute and chaos in space
When reading around for my piece yesterday on the wavefunctions of quantum mechanics, I stumbled across an old and fascinating debate about Saturn’s moon Hyperion. The question of how the smooth, classical world around us emerges from the rules of … Continue reading

What on earth is a wavefunction?
If you drop a pebble into a pond, ripples spread outward in gentle circles. We all know this sight, and it feels natural to call them waves. Now imagine being told that everything — from an electron to an atom … Continue reading
A ‘quantum consciousness’ absurdity at IIT Mandi
As you go downward, inward, smaller and smaller, you get more vast conscious experience. This is the idea in Indian knowledge systems. At the bottom of it, or the very base of it, at the source, is Brahman. My point … Continue reading
