"Information is the currency of nature." -- Seth Lloyd
Jen-Luc Piquant spent the entire week at the FQXI conference, exploring the foundational questions relating to the Physics of Information in the idyllic beachfront setting that is Puerto Rico's island of Vieques. (Seriously, why are more physics conferences not following suit? Especially in winter.) In between battling multiple bug bites -- the insects love Jen-Luc's tasty blood for some reason -- and a nighttime kayak in the famed bioluminescent bay, she thrilled to in-depth discussions on quantum computing, quantum information, cosmology, whether one can consider consciousness a form of information, whether information might turn out to be more fundamental than matter and energy, and of course, the black hole information paradox, which predictably drifted into a spirited, convoluted debate on the controversial subject of firewalls that might best be summed up as "Raphael Bousso Vs. Everybody Else" -- although, as Bousso pointed out repeatedly, remaining unconvinced by the various attempts to explain away the firewall paradox is not the same thing as "believing" that firewalls exist. Just sayin'.
Anyway, along with fellow SciAm blogger George Musser Jr., I was live-tweeting many of the talks, but you can't do justice to these kinds of topics in 140 characters. Mainly, I was hoping to pique people's interest into later listening to the audio of the talks, which are gradually being uploaded to the FQXI website.
I recommend starting with the opening panel: How do you define "Information"? Also be sure to catch Scott Aaronson's entertaining talk on the Church-Turing Hypothesis and its implications for quantum computing -- with a humorous segue into why a "Relatively Computer" might not be the best idea -- as well as the lively debate on whether free will exists, and Sean Carroll provocatively announcing that quantum fluctuations don't exist in De Sitter space, and thus there is no risk of Boltmann brains in that scenario (phew!). Those were just a couple that seemed to generate a lot of interest on Twitter; all the talks and panels are worth a listen -- but be forewarned, they're highly technical.
MIT's Max Tegmark organized the conference with Anthony Aguirre, and it just so happens that this week was the release of Tegmark's first popular science book, Our Mathematical Universe: My Quest for the Ultimate Nature of Reality. Motherboard was hot on the case of The Mathematical Reality of Reality: An Interview with Cosmologist Max Tegmark. Tegmark wrote his own blogpost: Why a Larger Multiverse Shouldn't Make You Feel Small. Related, from Ethan Siegel: Why we think there’s a Multiverse, not just our Universe.

Jen-Luc Piquant is well aware that while she was basking in the tropical setting of Vieques, many of you were caught in a vicious "polar vortex" of record-breaking cold. She also lives in Los Angeles, which has fairly balmy temperatures all year round. Should you need to engage in some vicarious cathartic venting, late night TV host Jimmy Kimmel sent his Cousin Sal to throw snowballs at these smug jerks who happen to live in a "nice city" with "pleasant weather." As HuffPo put it. "Seriously, where do people in Los Angeles get off going to the beach while the rest of the country is freezing its collective tail off?"

National Geographic explained some of the science behind instant snow, ice fog, and frozen bubbles.

The New (and Cheaper) Physics: "One of the reasons that neutrino physics is becoming more and more popular and attractive is that it is, relatively speaking, cheaper than big accelerator physics compared to the cost of, for example, the Large Hadron Collider. ...
