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.

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?
