HotBits is an Internet resource that brings genuine random numbers, generated by a process fundamentally governed by the inherent uncertainty in the quantum mechanical laws of nature, directly to your computer in a variety of forms. HotBits are generated by timing successive pairs of radioactive decays detected by a Geiger-Müller tube interfaced to a computer. (Warning: random sounds.)

The Reality Tests. "A team of physicists in Vienna has devised experiments that may answer one of the enduring riddles of science: Do we create the world just by looking at it?"

Physicists have 'solved' mystery of levitation Professor Ulf Leonhardt and Dr Thomas Philbin, from the University of St Andrews in Scotland, have worked out a way of reversing ... the Casimir force, so that it repels instead of attracts. Their discovery could ultimately lead to frictionless micro-machines with moving parts that levitate. But they say that, in principle at least, the same effect could be used to levitate bigger objects too, even a person.

PhET - Physics Education Technology offers this astoundingly large library of online physics simulations. Play orbital billiards. Land on a cheesy moon. Experiment with sound. Or try more advanced quantum physics simulators. Still bored? Try the "cutting edge" catagory. Here's the complete index. (Warnings: Frames, Flash, Javascript, Java applets, graphics, sound, quantum timesuck.)

Happy Anniversary, Quantum Mechanics! "On December 14, 1900, Max Planck presented experimental data at the German Physical Society and said that it could best be explained if energy existed in discrete packets, which he called "quanta." It was on that day that the field of Quantum Physics was effectively born. I call it QM Day and it's the unofficial start of the Agnostica Holiday!"

University of Arizona physicists have discovered how to turn single molecules into working transistors. The research could result in much smaller, more powerful computers and other devices with the ability to process many more channels of high-resolution audio and video than current products can manage. The abstract is available in PDF.

For a star as big as our universe the calculated vacuum energy inside its shell matches the value of dark energy seen in the universe today. "It's like we are living inside a giant dark energy star" say two physicists and their collegues. Dark energy stars may do away with the concept of black holes.

We've talked about quantum computation a few times before, but how much do we really know? Metafilter, instruct thyself. Don't forget to learn some advanced probability and computational complexity (Scott Aaronson has more).
Whoa, that's a lot o' learning, so let's so check out the much easier, and much cooler "sleeping puppy" experiment. I can only dream that will help break quantum mechanics' association with animal abuse. Then, there's the Free Will Theorem that just came out (some discussion on it) and another paper with a new look at an old problem. The latter describes another way of solving ye olde, super importanto Einstein-Podolsky-Rosen paradox using the relational interpretation of quantum mechanics (lots of discussion running around). Whew. We don't need the crackpot ramblings of What the #$*! Do We Know? when we've got real physics to keep us up at night. So, who wants to become a physicist? (t'Hooft has some thoughts for those who want to go theoretical.)

Natural selection acts on the quantum world. "Objective reality may owe its existence to a 'darwinian' process that advertises certain quantum states."

The physicist Shariah Afshar has used a beautifully simple experiment, which no-one seems to have thought of before, to disprove Bohr's principle of complementarity, something which has been pretty much unchallenged for 80 years. He may also have gone some way towards showing that there is no such thing as a photon, and that Einstein's Nobel prize should be revoked. So, big stuff. What do you physicists think?
