Edward Tufte, celebrated statistician and master of informational graphics, transforms physics notations into works of art. For example, “All Possible Photons” (pictured at right) “depicts in Feynman diagrams the 120 possible outcomes of a meeting of six discrete units of light. The steel wire sculptures are mounted inches from a wall and illuminated with light sources of varying qualities to create a three-dimensional appearance. The piece is composed of both the sculptures and the shadows they create.”

Shameless self-promotion alert! This week in Virtually Speaking Science, I chatted with physicist and author Ray Jayawardhana (a.k.a. “RayJay”) about hunting neutrinos. And speaking of neutrinos, the IceCube experiment has taken hits from three neutrinos carrying energies above the outlandishly high peta–electron volt range that suggest they may radiate from titanic explosions in the depths of space.
This is also my chance to plug the growing number of smart, beautiful young women with a passion for science who are making the most out of new media. For instance, here’s an interview with Gia Mora, actress, chanteuse, and all-around physics fan: E=MC What? ‘Einstein’s Girl’ Seeks Formula For Love. “You can be female and feminine and still be interested in these things,” said Mora. “It doesn’t have to be this stereotypical nerd girl, glasses and mousy hair and all of that. You can have the glam, and the goof, and the geek all in one thing.”
I recently chatted with host-with-the-most Cara Santa Maria in the latest episode of her new Talk Nerdy podcast, about the science of self, my work with the Science & Entertainment Exchange, and why I earned a black belt in jujitsu (as well as why I eventually quit martial arts).
I also visited with the smart and sassy women of the new BiteSizeTV Webseries, Chaotic Awesome, about self, identity, Second Life, and LSD — as well as a panel segment called The Fellowship of the Thing, where we talked about the XPrize for Artificial Intelligence. That’s Chloe Dykstra, Michele Morrow and Christina Ochoa with me on set in the clip below (not shown: correspondent Marisha Ray). The show’s title alludes to the moral alignment grid from Dungeons and Dragons (in which good and evil can be lawful, neutral or chaotic):

A physics grad student’s take on high frequency trading. “HFT has simply computerized age-old tactics.”It’s easy to point to extreme examples of algorithmic traders abusing markets, and they regularly do, but my argument is that HFT has simply computerized age-old tactics. In this process, these tactics have become more benign and markets more stable.” Adam Frank had a more agnostic take: High Frequency Trading is creating a new version of human time. “Are all time logics equal? Are all time logics good? Are all time logics sane? As we rush headlong into this new world of milliseconds, microseconds and nanoseconds, the time to address these questions is probably now.”

The Ethereal Daytime Long Exposure Photography of Darren Moore: “Moore creates ethereal black and white landscapes using a method called daytime long exposure, where a special filters are attached to a camera lens to reduce the amount of light. These neutral density filters allow for the shutter to open for extended periods of time in broad daylight, from 30 seconds to upward of 15 minutes for a single exposure.”
Trap doors – the answer for people moving seats at the theatre? “In 1924, Louis J Duprey of Dorchester, Massachusetts, patented a system that ‘permits any patron of the theatre to enter or leave his place without at all disturbing other patrons.’ You, the patron, entered vertically, though a trap door, already ensconced on a chair. When you wanted to leave, a discreet twist of a knob activated the machinery in reverse, causing the chair, and you, to quietly sink back down, and out.”
Off mass-shell: When a particle physicist describes something as “off mass-shell”, they could be referring to a precise bit of quantum mechanics, or denouncing an unrealistic budget estimate. Either way, it’s a bit of jargon that connects Pythagoras to the Large Hadron Collider, via Einstein and Feynman.

“There was once a princess who fell in love with geometry: Step Inside an Interactive Escher Drawing with Monument Valley. This game looks seriously amazing. “Heavily influenced by the drawings of M.C. Escher the game is so aesthetically beautiful the developers include an in-game camera that lets you take pictures you can share as you play. But this game isn’t just about pretty architectural landscapes, the gameplay is as entertaining as it is brilliant—instantaneous changes of perspective and gravity propel the game forward in unexpected ways.”

Shattered Mirror Sunset Reflections That Look Like Stained Glass Windows, by New York artist Bing Wright. Per the James Harris Gallery Website: “Wright photographs sunsets, then projects the images onto mirrors he has broken in the studio. The mirrors are small, measuring just 14 x 11 inches. The artist re-photographs the reflection and then enlarges the image into a large scale format.” (h/t: Twisted Sifter)

The Stark Dignity of Self-Organization in the poetry of William Carlos Williams.
In his poem “Spring and All”, Williams describes the reemergence of biological forms at the end of winter’s barrenness. Winter is characterized by a lack of form with words like “mottled”, “waste”, “fallen”, and “scattering”, while the colors are reddish, brown, or purplish – no green anywhere.
Against the waste and cold wind, living forms slowly appear, naked and uncertain at first, but they soon take on more “defined” shapes: a “stiff curl”, the “outline of leaf”, until these newly self-organized living things make their entrance with “stark dignity” as they “begin to awaken.”
