Just thought I’d point out a few interesting science posts around the web, for those who might not have stumbled upon them:
Blake Stacey at Science After Sunclipse is doing his best to shed readers with an excellent, but mathematical, post about the Dirac equation. Dirac’s mixing of special relativity and quantum mechanics led to the prediction of antimatter, and also naturally incorporated quantum-mechanical spin.
Tom at Swans on Tea points out that it is officially ‘Talk Like a Physicist Day‘. So I ‘propagated’ to work today instead of ‘drove’, and instead of ‘eating lunch’ I’ll be ‘extracting energy from organic compounds.’
Chad Orzel at Uncertain Principles describes some recent interesting optical four-wave mixing experiments and their implications.
Over at PLEKTIX, Ben Allen gives a non-technical discussion of ‘causality’ in special relativity and, in essence, who to blame when something goes wrong!
