Immaterials: Light painting WiFi

This project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-metre long measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.

The Universe May Be Recycled
A new analysis of leftover radiation from the Big Bang suggests the universe was recycled over and over again. Two theoretical physicists claimed in November  that circular patterns in the otherwise uniform cosmic microwave  background, which records the first light emitted after the beginning of  the universe, mean the universe didn’t go through one massive growth  spurt in its first fraction of a second, as most cosmologists currently  believe.
Instead, the universe as we know it could be just the most recent  iteration in a long cycle of births and deaths. The circles in the  microwave background could be the gravitational echoes of supermassive  black holes colliding in the epoch before the most recent Big Bang,  meaning there has been more than one Big Bang.
But the circles could also be noise. The controversial theory could  be settled by a new microwave background mapper, the Planck satellite,  which released its first map of the universe’s earliest light in July.

Berkeley Bionics eLegs
The feel-good gadget story of the year, without a doubt, was a lightweight exoskeleton from Berkeley Bionics that can help paraplegics walk again.
At the company’s press conference, a person who’d been paraplegic for 18 years demonstrated the eLEGS by walking around onstage.
Her smile shows you everything you need to know about this remarkable invention.
You probably can’t buy one, as it will cost around $100,000. But it’s  the sort of thing that a hospital or physical therapy clinic might buy  to help people do rehabilitation exercises, which can be especially  beneficial for people who were recently injured. That’s because the  eLEGS can help them get started on load-bearing, upright, walking  exercises while they still have the muscle memory for walking.
The eLEGS exoskeleton is not the only such device: A company called ReWalk makes a similar, $100,000 gadget that appeared on Glee this month.

What the F**k is Social Media NOW?

An excellent presentation on social media today and its impact on our world.

English will fade as a lingua-franca, but not because some other language will take its place … English will have no successor because none will be needed. Technology, Mr. Ostler believes, will fill the need.
The English language is doomed (to be usurped from its global ubiquity). (via utnereader)

10 futuristic materials:1. Aerogel (seen here protecting crayons from a blowtorch.)
Aerogel holds 15 entries in the  Guinness Book of Records, more than any other material. Sometimes called “frozen smoke”, it’s 99.8% empty space, which makes it look semi-transparent. Aerogel is a fantastic insulator — if you had a shield of aerogel, you could easily defend yourself from a flamethrower.
It stops cold, it stops heat. You could build a warm dome on the Moon. Aerogels have unbelievable surface area in their internal fractal structures — cubes of aerogel just an inch on a side may have an internal surface area equivalent to a football field. Despite its low density, aerogel has been looked into as a component of military armor because of its insulating properties.
