From the Heisenberg cut to the Copenhagen interpretation
The following post was motivated by this exchange (on X.com), which prompted me to write out my understanding of the Copenhagen interpretation of quantum mechanics and the part the Heisenberg cut plays in it. I haven’t gone into the variants … 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
The Kapitza pendulum
Rarely does a ‘problem’ come along that makes you think more than casually about the question of mathematics’s reality, and problems in mathematical physics are full of them. I came across one such problem for the first time yesterday, and … Continue reading
The calculus of creative discipline
Every moment of a science fiction story must represent the triumph of writing over world-building. World-building is dull. World-building literalises the urge to invent. World-building gives an unnecessary permission for acts of writing (indeed, for acts of reading). World-building numbs … Continue reading

Scientists make video of molecule rotating
A research group in Germany has captured images of what a rotating molecule looks like. This is a significant feat because it is very difficult to observe individual atoms and molecules, which are very small as well as very fragile. … Continue reading

Bohr and the breakaway from classical mechanics
One hundred years ago, Niels Bohr developed the Bohr model of the atom, where electrons go around a nucleus at the center like planets in the Solar System. The model and its implications brought a lot of clarity to the … Continue reading

Thinking quantum
In quantum physics, every metric is conceived as a vector. But that’s where its relation with classical physics ends, makes teaching a pain. Teaching classical mechanics is easy because we engage with it every day in many ways. Enough successful … Continue reading
The philosophies in physics
As a big week for physics comes up–a July 4 update by CERN on the search for the Higgs boson followed by ICHEP ’12 at Melbourne–I feel really anxious as a small-time proto-journalist and particle-physics-enthusiast. If CERN announces the discovery … Continue reading
