Nima Arkani-Hamed is championing a campaign to build the world's largest particle collider - "Two years ago, he agreed to become the inaugural director of the new Center for Future High Energy Physics in Beijing. He has since visited China 18 times, campaigning for the construction of a machine of unprecedented scale: a circular particle collider up to 60 miles in circumference, or nearly four times as big around as Europe's Large Hadron Collider (LHC). Nicknamed the 'Great Collider', and estimated to cost roughly $10 billion over 30 years, it would succeed the LHC as the new center of the physics universe. According to Arkani-Hamed and those who agree with him, this 100-trillion-electron-volt (TeV) collider would slam subatomic particles together hard enough to either find the particles that the LHC could not muster or rule them out, rescuing or killing the naturalness principle and propelling physicists toward one of two radically different pictures: that of a knowable universe, or an unknowable multiverse."

In a Multiverse, What Are the Odds? "Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics." (previously) [more inside]
Decades of confounding experiments have physicists considering a startling possibility: The universe might not make sense. For you Saturday night science read, a very interesting science article, one of many on the Simons Foundation web site
foundational notions of classic science fiction seem to be moving closer to reality there's way more here than I am capable of comprehending, but anything that talks about Minkowski spacetime has my attention.
The Nature of Computation - Intellects Vast and Warm and Sympathetic: "I hand you a network or graph, and ask whether there is a path through the network that crosses each edge exactly once, returning to its starting point. (That is, I ask whether there is a 'Eulerian' cycle.) Then I hand you another network, and ask whether there is a path which visits each node exactly once. (That is, I ask whether there is a 'Hamiltonian' cycle.) How hard is it to answer me?" (via) [more inside]
Holt’s philosophers belong to the twentieth and twenty-first centuries. Compared with the giants of the past, they are a sorry bunch of dwarfs. They are thinking deep thoughts and giving scholarly lectures to academic audiences, but hardly anybody in the world outside is listening. They are historically insignificant. At some time toward the end of the nineteenth century, philosophers faded from public life. Like the snark in Lewis Carroll’s poem, they suddenly and silently vanished. So far as the general public was concerned, philosophers became invisible. [more inside]
Brian Greene's Fabric of the Cosmos is online in its entirety on NOVA's website, in four one-hour episodes. Time, Space, Quantum Mechanics, Multiverses.
The Glorious Hairy Tentacle of Judgment, the Lorentz-Fitzgerald Contraction and the Absence of Smerlox Braff
"Scenes from a Multiverse"* is a brand new webcomic from Jon Rosenberg, the Lonely Goatherd, developed when he recently realized that when his absurd magnum-opus reaches its pre-destined conclusion (on the Mayan-designated Dec. 21, 2012), the impressive bound volumes of the story were not going to pay for his kid's college education. So here are daily visits to random levels of existence (if you assume all those levels of existence contain strange beings a lot like people you find annoying) without the bothersome story arc. PLUS the opportunity to vote for the alternate universe you'd like to revisit! (bonus previ-eewww content) [more inside]

Homicide: Life on the Street Crossovers & A Multiverse Explored An amazing piece of tv research. Did you know that almost all US television happened in the mind of Tommy Westphall, the autistic child in 'St. Elsewhere'? Some 163 series from 'Friends' to 'The X-Files'. Don't you just love crossovers?
