There is much to celebrate this week. For instance: Happy Manhattanhenge! Celebrate with Neil deGrasse Tyson’s hand-drawn love letter to the urban miracle. It was also Nikola Tesla Day, which The Oatmeal commemorated by reminding us of his classic comic on the great late 19th century inventor. It was also Buckminster Fuller’s birthday this week, which Brain Pickings celebrated by highlighting his Scientific Prayer: “A secular definition of divinity as a curiosity-driven love of truth bent through the prism of our subjective experience.”
This week in shameless self-promotion: I have a new blog post up at Nautilus: Reading the Tea Leaves: How Particles Can Travel Upstream. Thankfully, this is one question we can use bourbon to answer.
“As a child I fell in love with technology, but I have to admit I never fell in love with science. ” Such were the opening lines of the column — entitled “Why I Am a Creationist” (link bait alert!) — that launched what Jen-Luc Piquant calls L’affaire Heffernan. Heffernan is a former New York Times technology and culture columnist (and a former fact checker at the New Yorker), who is bizarrely anti-science. Jen-Luc was dismayed to learn that she holds a PhD in English from Harvard. One expects a bit more from an Ivy League education than the sloppy thinking on display in this column. Gawker naturally brought the skewering snark, concluding that Heffernan’s column “amounts to a very specific guide as to why Virginia Heffernan should no longer be taken seriously.” Colin Schultz went for a visual skewering on Tumblr.
Also weighing in with thoughtful commentary were Razib Khan, Janet Stemwedel, and Jerry Coyne, who pronounced the piece “a celebration of willful ignorance,” concluding (a bit unfairly): “This is what comes from postmodernism. Forget the facts, who’s got the better narrative?” Carl Zimmer engaged with her via Twitter [Storify here] and explained why he bothered in the first place, “Heffernan’s column is not very important in itself, but it speaks to broader attitude that is worth taking on.”
Jen-Luc Piquant sincerely hopes that the science-minded community does not take Heffernan’s superficial ponderings as representative of the field of humanities as a whole. She stands with Adam Frank: “Science — in all its glory — is just too beautiful to be walled off. Perhaps it is some future union of art and science that will allow these truths and this beauty to become fully accessible to everyone.” The revolution is already happening. A guest blog post at Scientific American this week opined that artists and scientists are more alike than different. And with the opening of her new show “Transience,” English printmaker Susan Aldworth proves herself to be at the forefront of artists working side by side with neuroscientists. See? The “two cultures” need not be at war.
Here’s Chad Orzel on how to think like a physicist. “[P]hysicists, even more than other scientists, are inclined to abstract things away to get to the simplest and most universal principles. Even when that means that we end up working mostly with idealizations and first-order approximations.” Many times, “an approximation is good enough.”

The Time Lord and I totally geeked out over Pacific Rim, and we were not alone! Wired marked the occasion by exploring the question of how you might carry a Jaeger from Pacific Rim. io9 checked out the method behind the monsters, i.e., the design process behind their appearance, while editor Annalee Newitz boldly declared Pacific Rim to be “the greatest fairy tale of the 21st century.”

Modest Debut of Atlas May Foreshadow Age of ‘Robo Sapiens.’ Per the New York Times: “The robot — which is equipped with both laser and stereo vision systems, as well as dexterous hands — is seen as a new tool that can come to the aid of humanity in natural and man-made disasters.” BUT WILL IT FIGHT THE SPACE MONSTERS FOR US?!? Bonus: The First Robot, Created in 400 BCE, Was a Steam-Powered Pigeon.
The History of CTRL + ALT + DELETE. Back in 1981, David Bradley “created a keyboard shortcut that triggered a system reset without the memory tests. He never dreamed that the simple fix would make him a programming hero, someone who’d someday be hounded to autograph keyboards at conferences. And he didn’t foresee the command becoming such an integral part of the user experience.”

The Endless Immensity and Finite View of the Infinite of Thomas Wright, 1754. “In his book, An Original Theory or New Hypothesis of the Universe, Founded upon the Laws of Nature, he described a version of the universe that was influential in the thinking of Kant and Herschel, finding a rectangular/squashed ‘finite infinity’ of stars, ‘a vast infinite Gulph, or Medium, every Way extended like a Plane, and inclosed between two Surfaces.’”

Two spheres of the same size, shape, and material are dropped into water. One splashes, the other doesn’t. What gives? “It all comes down to the surface treatments. The glass sphere on the left is hydrophilic, but the right one has been treated to be hydrophobic. As a result, the water-fearing molecules of that sphere push the water away, allowing air to be entrained below the water’s surface instead. This creates a big splash that’s absent when the water moves smoothly around the hydrophilic sphere.”

Rules of quantum theory shine light on the brain and how people make decisions. Wolfgang Pauli “proposed that the interaction between consciousness and unconsciousness is analogous to one of the central ideas in quantum physics, called complementarity – that it is impossible to distinguish between the behaviour of an atomic object and its interaction with the instrument observing it.” [Sub required; go on, support good science writing!]
