Quantum Mechanics, PETA approved.
If you are a physics student, or a non-physicist who happens to be simply curious about quantum mechanics, you should read Quantum Puppies by Sean Carroll over at Cosmic Variance. Well, OK, the title is really “Quantum interrogation”, but it’s cleverly done with a friendly, non-lethal puppy analogy, rather than the dead cat in the box analogy. It’s also very well written.
Sean Carol has won the AntiBogon of the Day Award. Congratulations, Sean, for helping to attenuate the bogon flux.
