"You named your collaboration QAP? Really?"

The DiVincenzo Code [youtube trailer, geekery]. Faced with a strict demand from a funding agency to allocate research funds towards the dissemination of research ideas to the public, an experimental physics group at the University of Oxford produced a feature-length (55 min) action thriller about murder, ancient prophecy, tea breaks, and quantum computation. [Trailer linked above. Parts 1 2 3 4 5 6] Named after the most basic requirements for a functional quantum computer, the DiVincenzo criteria [pdf], the student-directed effort is a superposition of The Da Vinci Code, The Matrix, and a live-action PhD Comics. Perhaps best viewed with either popcorn or your lab-mate's stash ofThorlabs Lab Snacks.

Silly pencil pushers! You can't KILL Physics! What's that? Oh, physics research. You've won this round!

RIP Bell Labs "After six Nobel Prizes, the invention of the transistor, laser and countless contributions to computer science and technology, it is the end of the road for Bell Labs' fundamental physics research lab."

Physics milestones of the past 50 years

Physical Review Letters' 50th anniversary retrospective promises to be an interesting survey of the physics landscape for the past half-century.

Ride the Lightning

Nova Science Now recently ran a segment on lightning (quicktime, real, and windows video here). I figured that subject was over and done with shortly after Franklin flew a kite, but it turns out we don't really know exactly what causes a bolt to start. The coolest part of the segment was these researchers in Florida. Scientists know how hard it was to observe, monitor, and even find lightning bolts, so these guys built their own rig. High-powered model rockets attached to a couple thousand feet of wire, which is grounded to larger metal structures on the ground. The result? Shoot a rocket into a storm cloud and you get instant lightning you can count on, measure, and control.

Negative knowledge (or more precisely negative information)

Know less than nothing!? What could negative knowledge possibly mean? In short, after I tell you negative information, you will know less... "In this week's issue of Nature, however, Michal Horodecki and colleagues present a fresh approach to understanding quantum phenomena that cannot be grasped simply by considering their classical counterparts."

The Complexity of a Controversial Concept

The Logic of Diversity "A new book, The Wisdom of Crowds [..:] by The New Yorker columnist James Surowiecki, has recently popularized the idea that groups can, in some ways, be smarter than their members, which is superficially similar to Page's results. While Surowiecki gives many examples of what one might call collective cognition, where groups out-perform isolated individuals, he really has only one explanation for this phenomenon, based on one of his examples: jelly beans [...] averaging together many independent, unbiased guesses gives a result that is probably closer to the truth than any one guess. While true — it's the central limit theorem of statistics — it's far from being the only way in which diversity can be beneficial in problem solving." (Three-Toed Sloth)

Voices from the past

Getting back into the groove : In the corner of a California university laboratory, two men are battling against time to perfect a machine that will read old recordings - using special microscopes to scan the grooves - and software that can convert those shapes into sound. Their work could bring history to life.

News outlets make neutrino hash

ptermit — Mon, 09 Dec 2002 12:33:59 -0800

What's the real story here? "An international team researching particle physics at Tohoku University has observed a new kind of neutrino." BZZT! Try again."Sun is ok, says latest neutrino experiment." BZZT. Wrong answer. The media sure made a hash out of this one. [more inside]

"The Standard Model" of the universe takes a hit.
Score one for string theorists. Scientists at the Brookhaven National Laboratory appear to have discovered a new type of subatomic particle that would disprove the currently accepted model for the nature of space and matter.
