Basic Mechanics in Fire Control Computers

I've never really had a clear understanding of how mechanical computing worked, until today when I watched these US Navy training films from 1953. Part 1 focuses on shafts, gears, cams and differentials. Part 2 explains mechanical component solvers, integrators and multipliers. More information about ship gun fire-control systems here.

The Great Northern Concrete Toboggan Race

For 36 years, engineering students from colleges across North America (and beyond) have aspired to succeed at winter's most prestigious, most arduous, most ridiculous challenge - to build and ride the world's fastest sled . . . made of concrete. Tomorrow, if you're in the greater Hamilton Ontario area, you can witness the Great Northern Concrete Toboggan Race yourself.

All we hear is radio ga ga.

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.

Great Lakes to be filter-fed to carp

Asian Carp update: since 2003(previously), the inexorable advance of Asian Carp up the Mississippi delta has brought them to within 6 miles of Lake Michigan. These invasive "100-pound Zebra Mussels" suck rivers clean and starve native fish. Asian Carp are now 97% of the fish biomass in the Mississippi delta. The "electric fence" across the canal didn't stop them. The poisoning of the canal won't stop them. Closing the Chicago sewage canal locks is the only way to be sure. But the Army Corps of Engineers have the jurisdiction. Feel safe? [more inside]

a pink sliver of rat brain sat in a beaker

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 1 2 3 4) [more inside]

Photographs of the Excitement of Geotechnical Engineering (Failures)

Professors Ross W. Boulanger and Dr. James Duncan have put together a Geotechnical Engineering Photo Album, with details of the successes and disasters. The album includes compaction techniques for a highway off-ramp, deep excavation methods, an offshore tank structure, and earthquake hazards of many sorts (mountain landslides, liquefaction damage to ports in Kobe, Japan, surface rupture in Taiwan, and problems with shallow foundations and subsidence in Turkey).

Neurosecurity

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."

People doing strange things with electricity

Dorkbot is a "monthly meeting of artists (sound/image/movement/whatever), designers, engineers, students, scientists, and other interested parties who are involved in the creative use of electricity." Started in NYC in 2000 by Douglas Repetto, Director of Research at the Columbia University Computer Music Center as well as one of Wired's 10 Sexiest Geeks, there are now dozens all over the world. Past presenters have been featured here on the blue. For instance Jeff Han presented his multi-touch interface at dorkbot-nyc in April of 2006.

The Lackawanna Cut-Off

A glance will show / Why Phoebe Snow / Prefers this route / To Buffalo.
And Phoebe's right / No route is quite / As short as Road / of Anthracite.


In 1908 the Delaware, Lackawanna and Western Railroad began work on the New Jersey Cut-Off to make its New York to Buffalo mainline (the Road of Anthracite so liked by Phoebe Snow) even shorter and faster. It was to have no grade crossings, and was to be as straight and level as possible — through hilly terrain. The 28-mile Lackawanna Cut-Off, as it is now known, was built over three years, cost $11 million, and was an engineering marvel of massive reinforced concrete bridges, enormous cuts, and the largest railroad embankment in the world. All of this has been abandoned for years, though there are plans afoot to restore the Cut-Off for commuter rail. [more inside]

What Good Is Half A Machine?

One of the classic arguments against evolution by natural selection is "what good is half an X?" where X is an eye, a wing or some other complex body part or system. Directly responding to the implicit challenge some researchers have been not just figuring out how X could have evolved, but actually evolving new complex machines (previously). The basic ideas are so simple that web versions (explanation and discussion) have been popping up.

The Man Who Invented Stereo

In a single 1931 document, electrical engineer Alan Blumlein patented stereo records, stereo movie sountracks and surround sound. His equipment was used to make some of the first stereo recordings at EMI's Abbey Road studios - several decades before the technology came into popular use. Blumlein went on to pioneer 405 line TV (the first wholly electronic format which won out over John Logie Baird's rival system) and to produce the equipment that made the first outside TV broadcast possible. At the outbreak of World War 2 he was a key architect of the secret H2S radar project. Unfortunately he was killed in a plane crash while testing the technology and the whole incident was kept secret. Hence he remains an obscure figure despite his achievements. A recent BBC Radio 4 program contains a lot of the archive stereo footage and tells his story.

He created a ghost ship, uninhabited and self navigated, and continues to surprise with his latest work.... [more inside]
