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]
Hollaback and Why Everyone Needs Better Research Methods (And Why All Data Needs Theory), by Zeynep Tufekci:
I’ve taught "introduction to research methods" to undergraduate students for many years, and they would sometimes ask me why they should care about all this "method stuff", besides having a required class for a sociology major out of the way. I would always tell them, without understanding research methods, you cannot understand how to judge what you see.[more inside]
The Hollaback video shows us exactly why.
Understanding Jean Baudrillard with Pumpkin Spice Lattes "Back in the day you were stuck with what was seasonal – you ate tomatoes and watermelon when it was summer, and when old man winter rolled in, you were stuck with nature’s shit bag – like potatoes and kale – a vegetable god intended you to hate and smite you with."

Act 1, scene 1. "The stage directions read, “Vienna. The Ringstrasse promenade at Sirk Corner. Flags wave from the buildings. Soldiers marching by are cheered by the onlookers. General excitement. The crowd breaks up into small groups.” The newsboys with their “Extra Extra,” announcing the outbreak of war, are interrupted by a drunk demonstrator who shouts “Down with Serbia! Hurrah for the Hapsburgs! Hurrah! For S-e-r-bia!” and is immediately kicked in the pants for his mistake (LTM, p. 69). A crook and a prostitute exchange insults, even as two army contractors, talking of possible bribes the rich will use to avoid the draft, cite Bismarck’s words, in Neue Freie Presse (Vienna’s major newspaper at the time of the assassination of the archduke in Serbia), to the effect that the Austrians deserve kissing. One officer tells another that war is “unanwendbar” (of no use) when he really means, as his friend points out, “unabwendbar” (unavoidable) (LTM, pp. 70–71). A patriotic citizen praises the coming conflict as a holy war of defense against “encirclement” by hostile forces, and the crowd responds by making up rhymes (in Viennese dialect) denigrating the enemy (LTM, p. 72)."

"Advertising is not well. Though companies supported by advertising still dominate the landscape and capture the popular imagination, cracks are beginning to show in the very financial foundations of the web. Despite the best efforts of an industry, advertising is becoming less and less effective online. The once reliable fuel that powered a generation of innovations on the web is slowly, but perceptibly beginning to falter. Consider the long-term trend: when the first banner advertisement emerged online in 1994, it reported a (now) staggering clickthrough rate of 78%. By 2011, the average Facebook advertisement clickthrough rate sat dramatically lower at 0.05%. Even if only a rough proxy, something underlies such a dramatic change in the ability for an advertisement to pique the interest of users online. What underlies this decline, and what does it mean for the Internet at large? This short [PDF] paper puts forth the argument for peak advertising—the argument that an overall slowing in online advertising will eventually force a significant (and potentially painful) shift in the structure of business online. Like the theory of Peak Oil that it references, the goal is not to look to the immediate upcoming quarter, but to think on the decade-long scale about the business models that sustain the Internet."

In Theory is a column in Ceasefire Magazine that introduces and reflects on major figures in cultural/political/literary theory (Agamben 1 2; Althusser 1 2; Amin 1 2; Appadurai 1; Aristotle 1 2; Badiou 1 2; Bakhtin 1 2; Bakunin 1 2 3; Barthes 1 2 3 4 5 6; Baudrillard 1 2 3 4 5 6 7 8 9 10 11 12 13 14; Benjamin 1 2 3 4 5 6 7 8; Deleuze 1; and Marcuse 1) in addition to discussing general topics such as anarchism, asymmetrical war, autonomism, commodity fetishism, global cities, local knowledge, peacekeeping, and precarity.
Computers are providing solutions to math problems that we can't check - "A computer has solved the longstanding Erdős discrepancy problem! Trouble is, we have no idea what it's talking about — because the solution, which is as long as all of Wikipedia's pages combined, is far too voluminous for us puny humans to confirm." (via; previously ;)
Network Theory Overview - "The idea: nature and the world of human technology are full of networks! People like to draw diagrams of networks. Mathematical physicists know that in principle these diagrams can be understood using category theory. But why should physicists have all the fun? This is the century of understanding living systems and adapting to life on a finite planet. Math isn't the main thing we need, but it's got to be part of the solution... so one thing we should do is develop a unified and powerful theory of networks." (via ;)

Closing in on the twin prime conjecture (Quanta) - "Just months after Zhang announced his result, Maynard has presented an independent proof that pushes the gap down to 600.

Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality -- forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided "master amplituhedron," whose geometry represents the sum total of all physical interactions.

Though it is common to lament the shortcomings of reading an important work in any language other than the original and of the “impossibility” of translation, I am convinced that works of philosophy (or literature for that matter — are they different?) in fact gain far more than they lose in translation.

Always totalize! This is the majuscule axiom — the maxiom, let us say — for revolution. Revolution is a total thought, a thought of the totality; they are necessarily entangled. Reform, repair, regime change, recuperation: all of these are the politics of the partial, of isolating specific problems as if they admitted of independent solution. Ezra Pound said that the epic is a poem that contains history. What matter that we might amend the last word, a minor amendment at that, a swapping out of inseparable concepts? The epic is the poem that contains totality. [more inside]

"But The Shining speaks to what makes Kubrick such an interesting and, for a lot of people, troublesome filmmaker, because he does not give you what you want. At all. He does not give you a Vietnam movie set in the jungle, and he does not give you a horror movie that is just like Stephen King’s The Shining. He doesn’t even give you scares for a long time, [just] ominous foreboding. And it takes people a while to figure out, “Oh, maybe I don’t know what I want. Maybe this is better.” - Mefi's Own Jon Hodgman talks about Full Metal Jacket with Scott Tobias for "The Last Great Movie I Saw."
Every Pixar movie is connected. I explain how, and possibly why. Several months ago, I watched a fun-filled video on Cracked.com that introduced the idea (at least to me) that all of the Pixar movies actually exist within the same universe. Since then, I’ve obsessed over this concept, working to complete what I call “The Pixar Theory,” a working narrative that ties all of the Pixar movies into one cohesive timeline with a main theme.

Now, a technological advance has made it possible for physicists to test the idea. They plan to build a time crystal, not in the hope that this perpetuum mobile will generate an endless supply of energy (as inventors have striven in vain to do for more than a thousand years) but that it will yield a better theory of time itself.Nobel laureate Frank Wilczek's "somewhat embarassing" idea will be put to the test as scientists try to build time crystals.
Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]

"The models we discuss belong to the class of two-variable systems with one delay for which appropriate delay stabilizes an unstable steady state. We formulate a theorem and prove that stabilization takes place in our case. We conclude that considerable (meaning large enough, but not too large) values of time delay involved in the model can stabilize love affairs dynamics." [more inside]
Thomas Frank (of What's the Matter with Kansas? and Pity the Billionaire fame) reviews Occupy's burgeoning research program in "To the Precinct Station."
"Dear god why, after only a few months of occupying Zuccotti Park, did Occupiers feel they needed to launch their own journal of academic theory? A journal that then proceeded to fill its pages with impenetrable essays seemingly written to demonstrate, one more time, the Arctic futility of theory-speak? Is this how you build a mass movement? By persistently choosing the opposite of plain speech?"He also approvingly cites Slavoj Žižek's essay on the dangers and opportunities of the carnival here.

"Liberals have not always been very good at communicating why liberalism works. There’s many reasons for this, but part of it is that it can be hard to defend the obvious from an absurd and deceptive attack. For half a century you had to be a crank to oppose what Roosevelt accomplished; liberals got out of the habit of arguing for their beliefs. I hope this page will help. Liberals don’t need to apologize for their vision of how American society should work. Liberalism saved American capitalism and democracy, defeated Naziism, created a prosperous middle class, and benefited every sector of society, from the back streets to Wall Street.

THE FULLER MAP This document is a study of the comprehensive designer Buckminster Fuller, an outstanding character of the 20th century, and a kind of practical visionary. [...] This presentation of his ideas is not intended as a slavish devotional exercise, nor a piece of cynical criticism. Part of the plan here is to investigate the logic of synergetics. At this stage the account is verbal, not visual, but what is important in geometry is the logic rather than the pictures. The text is a work-in-progress, begun in August 1991, and originally written to meet the structural requirements of John Wood's IDEAbase system. It was compiled and edited as an experimental, dynamic, interactive, screen-based document. It was not, therefore, intended as a completed linear text to be printed onto paper or other static medium.

In the late 1970s the UK's Anglia Television ran a respected weekly documentary series: Science Report. But when the show was cancelled in 1977, the producers decided to channel Orson Welles in their final episode. The result was Alternative 3. Over the course of the hour, the audience would learn that a Science Report investigation into the UK "brain drain" had uncovered shocking revelations: man-made pollution had resulted in catastrophic climate change, the Earth would soon be rendered uninhabitable, and a secret American / Soviet joint plan was in place to establish colonies on the Moon and Mars. The show ended with footage of a US/Soviet Mars landing from May 22, 1962. After Alternative 3 aired, thousands of panicked viewers phoned the production company and demanded to know how long they had left to change planets. [more inside]

But like many an inarticulate young lover, I thought for a time that seduction was a matter of giving the right book to the right woman. In my case it was Barthes’s A Lover’s Discourse: a meditation on Goethe’s Sorrows of Young Werther that catalogues the melancholic lover’s prized ‘image repertoire’ – the scene of waiting, the feeling of being dissolved in the presence of the loved being, the attraction of suicide – and thinly veils the author’s own life as a middle-aged gay man in Paris in the 1970s. This gift was always a prelude to disaster.– RB and Me: An Education is an essay by Brian G. Dillon about his relationship with the books of French philosopher Roland Barthes. It's also a lovely autobiography of an awkward boy finding his place in life. Dillon's website collects his essays, and is trove of interesting insight. Besides writing essays and fiction, Dillon is also the UK editor of Cabinet Magazine, and you can read a fair number of his articles online, including ones on Beau Brummel and the cravat, hypochondria and hydrotherapy.
