"While the problem of consciousness is far from being solved, it is finally being formulated mathematically as a set of problems that researchers can understand, explore and discuss.
Today, Max Tegmark, a theoretical physicist at the Massachusetts Institute of Technology in Cambridge, sets out the fundamental problems that this new way of thinking raises. He shows how these problems can be formulated in terms of quantum mechanics and information theory. And he explains how thinking about consciousness in this way leads to precise questions about the nature of reality that the scientific process of experiment might help to tease apart.
Tegmark’s approach is to think of consciousness as a state of matter, like a solid, a liquid or a gas. 'I conjecture that consciousness can be understood as yet another state of matter. Just as there are many types of liquids, there are many types of consciousness,' he says."

You may have heard how sounds travel farther during a temperature inversion
, when air near the ground is cooler than the air above. But do you know how this phenomenon is related to the 1947 UFO crash in Roswell, New Mexico? [more inside]

The Great Ptolemaic Smackdown
is a nine-part series posted by sci-fi author and statistician Michael F. Flynn
to his blog last year, covering the historical conflict between heliocentrism and geocentrism, with a special focus on Galileo. They are based on an article (pdf)
by Flynn which originally appeared in the Jan/Feb 2013 issue of Analog

From I Fucking Love Science:
"In a paper posted online
this week Professor Stephen Hawking claimed that black holes do not exist - at least, not as we currently understand them. He claims that the traditional notion of a black hole's "event horizon" from which nothing can escape, even light, is incompatible with quantum physics. If so, physicists will have to redefine black holes entirely." [more inside]

A video showing a chain of beads
behaving in a very peculiar way appeared on Youtube some time ago. Many people attempted to provide explanations, but most of them weren't quite satisfactory. [more inside]
