Seven wonders of the quantum world (NewScientist)
NewScientist: Succinct, interesting overview of the quantum mechanical world, citing latest research.
"From undead cats to particles popping up out of nowhere, from watched pots not boiling – sometimes – to ghostly influences at a distance, quantum physics delights in demolishing our intuitions about how the world works.
- Wave-Particle Duality Light is both a particle and a wave – and we're starting to prove that everything else is too. Read more
- The Hamlet effect "A WATCHED pot never boils." Armed with common sense and classical physics, you might dispute that statement. Quantum physics would slap you down. Quantum watched pots do refuse to boil - sometimes. At other times, they boil faster. At yet other times, observation pitches them into an existential dilemma whether to boil or not.
..tests with larger and larger objects - including, recently, a resonating metal strip big enough to be seen under a microscope - seem to show that they really can be induced to adopt two states at once (Nature, vol 464, p 697).
The weirdest thing about all this is the implication that just looking at stuff changes how it behaves. .. Read more
- Spooky action at a distance Reality, free will or the speed of light? One's got to give, because quantum mechanics says you can't have them all.
in 2008 physicist Nicolas Gisin and his colleagues at the University of Geneva showed that, if reality and free will hold, the speed of transfer of quantum states between entangled photons held in two villages 18 kilometres apart was somewhere above 10 million times the speed of light (Nature, vol 454, p 861).
