In February 2011, every teacher in Providence, Rhode Island was pink slipped. Not all 1,926 of them got fired, of course, but with the district facing a $40 million deficit, anything is possible. The district says it needs flexibility, just in case. Every school district in the United States faces its own version of what’s happening in Providence. However, “
IMAGINATION: Creating the Future of Education and Work” is focused not on how we got here but rather how we can move forward from here immediately even as the education system continues to struggle.

Audiophoolery: Pseudoscience in Consumer Audio.
You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

The simulated brain - "The scientists behind
Blue Brain hope to have a
virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's
NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to
digitally simulate a brain accurately? Can it only
be analog? And are there
quantum effects to
be considered? (previously

Neurosecurity: security and privacy for neural devices. "An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define 'neurosecurity'—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices."

Imagine nature's most elegant ideas organized by design and engineering function, so you can enter "filter salt from water" and see how mangroves, penguins, and shorebirds desalinate without fossil fuels. That's the idea behind
AskNature, the online inspiration source for the
biomimicry community. The
featured pages are a good starting point. Cross-pollinating biology with design.

The coming memristor revolution in electronics and how it works. The newly created memristor, only the fourth fundamental fundamental type of passive circuit element, has the promise of computing advances both prosaic (faster, cheaper and "bigger" flash drives) and momentous (relatively effortless mimicry of brain cells and their activity). This is the story of the memristor's genesis, told by R. Stanley Williams, the leader of the team that created the device.

Where the Engineers Are - "To guide education policy and maintain its innovation leadership, the United States must acquire an accurate understanding of the quantity and quality of engineering graduates in India and China."

All the episodes of
The Secret Life of Machines are available online. Created by engineer, artist, tinkerer and cartoonist
Tim Hunkin, the show took a look at the science and mechanics behind common household objects, with a bit of social history, homemade laboratory experiments, and downplayed humor. The series grew out of a long-running strip, which Hunkin has now offers as his own
cartoon encyclopedia. You can also try some
experiments of your own, marvel at the
coin-operated contraptions he made for the
Under the Pier Show in Suffolk (don't miss the
film), and read his
thoughts about his brief foray into the fine art world and his
ruminations about how art and engineering mix.

Synthetic Trees could purify the air - "It looks like a goal post with Venetian blinds," said the Columbia University physicist...synthetic trees could help clean up an atmosphere grown heavy with carbon dioxide..."You can be a thousand times better than a living tree...There are a number of engineering issues which need to be worked out," he said. (BBC)
Hurry up, then -
"Ice dams are blocking Latvian ports, winds and storms are battering Europe, Portugal is freezing, Vietnam has lost one-third its rice crop, and the cold has caused close to 2,000 deaths in usually temperate South Asia."

Why the towers fell. PBS is airing a
special episode of Nova about the science behind while the World Trade Center towers collapse. Nova's reputation for converting esoteric science & engineering into understandable explanations for the layman should make the show something to watch. 7PM EDT/PDT on most PBS stations. Set your Tivos.
