FQXi Makes it into Forbes...
Oct 6, 2011
(...but not the rich list!). FQXi's Stephon Alexander's musings on faster-than-light neutrinos are quoted in Forbes. For his full thoughts, check out his blog post and read about his FQXi-funded research on neutrinos and the universe.

Is Reality Digital or Analog?
By Jarmo Matti Mäkelä
A report of a discussion with Isaac Newton.
Physics and the Integers
By David Tong
I argue that the integers are emergent. If we are looking to build the future laws of physics, discrete mathematics is no better a starting point than the rules of scrabble.
Quantum Graphenity
By Tobias Fritz
To a certain extent, this problem can be overcome by the simulation of models for fundamental physics by other physical systems. Here I focus on graphene as a particularly fascinating example of such a simulator.

Video Article: Through a Glass Darkly
By ANIL ANANTHASWAMY • Nov 1, 2011
Eight-dimensional numbers could be needed to handle string-theory’s 10-dimensional physics. This classic article, with new video content, also tackles the mystery of why elementary particles come in families of three—and maybe even how spacetime emerges in 4-dimensions.
