Anathem, Neal Stephenson's new book, is stupendous, possibly his best.  But his acknowledgments page (summarized in the print version and as expansive as ever on the Internet Reticulum) might be even more interesting, and poignant, especially as an introduction to the niftiest piece of metaphysics in the book: the quantum effects  (PDFs) of consciousness among many worlds.

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?"

The odd films of Neural Surfer. I've yet to watch them all but my fave so far is Little Things that Jiggle: Richard Feynman and Atomic Physics {google vid}, which is part of the Philosophy in less than five minutes (sometimes) series.

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."

Smolin vs. Susskind on the anthropic principle. For those keeping score: Stephen Hawking is for it. Brian Greene is not.

Jaron Lanier talks about philosophy, computer science and physics. Suppose poor old Shroedinger's Cat has survived all the quantum observation experiments but still has a taste for more brushes with death. We could oblige it by attaching the cat-killing box to our camera. So long as the camera can recognize an apple in front of it, the cat lives.

The cable clock. This clocks tells time, just like any other clock, but the movement of the hands is hypnotic and beautiful. To physicists, time is defined by quantum mechanics. A photon with energy h (Planck's constant) behaves as though it were oscillating once per second. For Philosphers, time is less concrete, and they love to talk about it. Western society lives by the clock - does it make a difference if this is the kind of clock that you live by? After all, everyone knows that time is money. If you have to be a clock watcher, does it help if the clock is as calming as the Cable Clock is?
