The observer at the end of time: Of immortal watchers and imaginary data

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]

"Mrs Chater demanded satisfaction and now you demand satisfaction."

Tom Stoppard's "Arcadia," Twenty Years Later. Novelist Brad Leithauser muses on "the finest play written in my lifetime": One sign of "Arcadia"'s greatness is how assuredly it blends its disparate chemicals, creating a compound of most peculiar properties. The play’s ingredients include sexual jealousy and poetasters and the gothic school of landscape gardening and duelling and chaos theory and botany and the perennial war between Classical and Romantic aesthetics and the maturing of mathematical prodigies.

direct realism

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]

Time-filling links

Aldo Cortesi blogs about the interface between computer science and visualisation. He has found some interesting applications for space-filling curves: making colour maps of images and of executable binary files. A bit more work and one can visualise entropy in binary files. The cryptographic material sticks out like a sore thumb. [more inside]

I Am Sitting In A Video Room 1000

The 'photocopy effect' applied to YouTube What happens when you record a video, upload it to YouTube, download it, and re-upload it over and over and over. After a while, it starts to look like this [30x] and this [175] and this [240] and this [750]. Inspired by Alvin Lucier's experimental composition, I am Sitting in a Room discussed here and here.

spacetime must organise itself in a way that maximises entropy

Gravity from Quantum Information
At the heart of their idea is the tricky question of what happens to information when it enters a black hole. Physicists have puzzled over this for decades with little consensus. But one thing they agree on is Landauer's principle: that erasing a bit of quantum information always increases the entropy of the Universe by a certain small amount and requires a specific amount of energy.

it from bit

Emergent Gravity - Erik Verlinde has a theory that "gravitational attraction could be the result of the way information about material objects is organised in space..." Here's some related weblog discussions and follow along on twitter! (via /. & bruces ;)

A xylowave occurs everytime an effect has no cause, or a cause has no effect.

When the circus came to town...

Defunct amusement parks. It has postcards and historical photos. It also has relatively current photos of parks in various states of disrepair. A great site for fans of entropy, like myself. (via Linkfilter)

Things Fall Apart.

Things Fall Apart. Particularly in urban environments. Individually, the moments of entropy-in-action caught here may not mean much; collectively, they recite a visual poem about decay. A slightly melancholy site for you insomniacs out there. (By the way, you have to scroll right to get to the thumbnails.)

Describing a New Entropy

Describing a New Entropy A reformulation of Boltzmann-Gibbs entropy by one Constantino Tsallis is causing quite a buzz/stir in the theoretical physics community. It was originally published in 1988, but it sounds like it's only recently hit its stride. There's going to be a conference on "Tsallis entropy" in October co-chaired by Murray Gell-Mann!
