On here, I’m going to share little nuggets of no-math physics, computing, AI and related fields. Inspired by Heisenberg’s yearning for “the joy of understanding how things really are”. I work very hard not to be wrong but shout loudly if I stray…

Are topology and quantum physics a match made in heaven?
This latest @quantinuum.bsky.social result is the most complete implementation yet of a quantum algorithm for studying knots. But there is much more to this ... my latest story @nature.com — and monster 🧵 ahead

‘Mind blowing’: quantum computer untangles the mathematics of knots
Algorithms for studying knots and other topological objects could have a quantum advantage.

Deep into Dance to the Tune of Life by Denis Noble (thanks for the Xmas gift, Dad!). Loving how biological relativity aligns with complexity theory. Check out @seanmcarroll.bsky.social’s recent solo episode on Emergence as a perfect primer:

Another record has been set for the most entangled logical qubits

Just a few months after the previous record was set, a start-up called Quantinuum has announced that it has entangled the largest number of logical qubits

I’m experiencing a renaissance in admiration for Steve Jobs. It’s time this is cool again.

Here’s a gentle interview between @geoffreyhinton.bsky.social and @faisalislam.bsky.social

Ends with the honest reflection that AI will probably make quite good journalists .. and quite good interviewers too (Faisal chuckles nervously)

Wonderful episode here with @doynefarmer.bsky.social speaking to @seanmcarroll.bsky.social

Top nugget:
Biology: Darwin’s insight was that competition led to speciation
Economics: Milton Friedman found that competition drives to equilibrium

I found myself cheering along at the Institute of Physics communication group meeting this week when Trent (co-founder of @cosmicshambles.com) shared his nine lessons for communicating science. Lesson one: do not do “scicomms”!
