Tall tales emerging from the shadows

Wow is this real? Or some sort of misinformation about US military technologies? Perhaps being spread in some attempt to reflect the total fear of terrorism that is nurtured within the US as a tool to demoralize those communities abroad that the US considers its enemies.

By analyzing the movements of human shadows in aerial and satellite footage, JPL engineer Adrian Stoica says, it should be possible to identify people from the way they walk – a technique called gait analysis, whose power lies in the fact that a person’s walking style is very hard to disguise.

It would be rather challenging to do, but quite interesting to see how stories like this propagate on the ground in places like Afganistan. That portion of the blogosphere that concerns itself with technoscience and national security have certainly been abuzz with this story, and there has been quite solid propagation of it. But at what point, if really ever, do these types of stories jump the fence, as it were, and enter the rumor mill of the third world? Do the US intelligence services study this sort of thing?

The implications of this are rather wild, in any event. On the one hand, it is another expression of the contemporary’s interest in reducing phenomena to a statistical trace. You are an aggregation of variables that correlate only in your instance. You went to that coffee shop today because there was an 80% chance of it.

Maybe terrorists will start wearing big puffy suits to obscure their shadows. Actually it sounds like a great market opportunity, selling surplus Willie Wonka and the Chocolate Factory costumes to terrorists…

Resolving the unresolvable cosmos

I believe it was Derrida who referred to nuclear warfare as a ‘remainderless event’ — something that could exist only as a fabulous bit of text, always just a fantasy of images standing in for the unimaginable. In light of such notions, this is a rather fun project that our civilization has spawned. A network of telescopes spanning 2800 miles across the earth have all pointed themselves to the black hole at the center of the galaxy:

“No one has seen such a fine-grained view of the galactic center before. We’ve observed nearly to the scale of the black hole event horizon – the region inside of which nothing, including light, can ever escape.” [link]

However, for something in someways just as distant, but in others much closer to the imagination, see the below composite of images recently transmitted back from the rover Phoenix of the Martian clouds floating along [link]:

The camera took these 10 frames over a 10-minute period from 2:52 p.m. to 3:02 p.m. local solar time at the Phoenix site during Sol 94 (Aug. 29), the 94th Martian day since landing.

The audacity of rhetoric

Slavoj Zizek on audacious words and how Barack Obama is reshaping acceptable language:

His greatest achievement to date is that he has, in his refined and non-provocative way, introduced into the public speech topics that were once unsayable: the continuing importance of race in politics, the positive role of atheists in public life, the necessity to talk with “enemies” like Iran.

And that is a great achievement, which changes the coordinates of the entire field. Even the Bush administration, having first criticized Obama for this proposal, is now itself talking directly with Iran. [link]

Regarding a technical comparison of popular music

Mark Wieczorek wrote an interesting piece a few years back trying to characterize what it is about the ‘sound’ of a certain decade’s popular music that makes it so. He does this by looking at frequency trends common to songs of a particular era, finding that changes in the fidelity of recording technology as well as other innovations seemed to attend the shift.

Not surprisingly, 300-500hz range where most speech tends to peak when recorded, and where, for instance, many of Edith Paif’s recordings center, is all largely deemphasized from the technically frenetic, ipod headphone optimized tracks of the early ’00s [link]

You can see it in the eyes, phantom planet syndrome it is

Brainloop is an interactive performance platform that utilizes a Brain Computer Interface (BCI) system which allows a subject to operate devices merely by imagining specific motor commands. These mentally visualized commands may be seen as the rehearsal of a motor act without the overt motor output; a neural synapse occurs but the actual movement is blocked at the corticospinal level. Motor imagery such as “move left hand”, “move right hand” or “move feet” become non-muscular communication and control signals that convey messages and commands to the external world. In Brainloop the performer is able – without physically moving – to investigate urban areas and rural landscapes as he globe-trots around virtual Google Earth. Through motor imagery, he selects locations, camera angles and positions and records these image sequences in a virtual world. In the second half of the performance, he plays back the sequence and uses Brainloop to compose a custom soundtrack by selecting, manipulating and re-locating audio recordings in real time into the physical space.

Sliding down the refractor’s tube

Because seeing things you haven’t seen before, imagining structures outside of one’s usual scale, has the tendency of increasing conceptual elasticity and being generally salubrious and delightful, this Flickr microscopy pool might be of interest:

If it is true that the devil is in the details…

then god must be in the nanoparticles:

Stained glass windows that are painted with gold purify the air when they are lit up by sunlight, a team of Queensland University of Technology experts have discovered.

Associate Professor Zhu huai yong, from QUT’s School of Physical and Chemical Sciences said that glaziers in medieval forges were the first nanotechnologists who produced colours with gold nanoparticles of different sizes.

Professor Zhu said numerous church windows across Europe were decorated with glass coloured in gold nanoparticles.

“For centuries people appreciated only the beautiful works of art, and long life of the colours, but little did they realise that these works of art are also, in modern language, photocatalytic air purifier with nanostructured gold catalyst,” Professor Zhu said. [link]

A vintage computer museum on the line

The ‘Working Computer Museum‘ is an organization run by a group of net artists in Sicily.  The Museum “is an interactive permanent exhibition where visitors can not only look vintage computers, but also try them, ‘put their hands on them’ using their old Operating Systems, softwares or reading their original manuals.

Most interestingly, however, for those of us not able to arrange a visit at the moment, is their online museum. From SPARCStation 5′s to VAXStation 4000′s running Unix System V to Solaris 9, visitors are welcome to telnet into a whole cadre of terminals to compile and explore to their hearts content. If you do login, do not miss the Star Trek text adventure game installed in the lobby. A list of machines and login addresses can be found here.

An upright and locked position: early aviation

In an old brief case, I came across a map of Western Europe published by National Geographic in 1929. One of the plates published in the margin included a map of the passenger airline service as it existed at the time.

[Link to full map ~1MB]

I imagine that the Budapest –> Vienna flight must have featured a rather marvelous bevy of passengers… Most of the flights in Europe at this point were conducted in re-purposed WWI planes, with rather rough conditions that were, apparently, best endured for less than two hours at a stretch.

Commercial aviation in France was not a serious prospect until after World War I. Because of widespread damage to railroads all over Europe, air travel offered a convenient alternative means of transportation. The cross-channel route from London to Paris also offered a tempting opportunity for enterprising entrepreneurs. Near the end of the war, on February 8, 1919, a group of French businessmen had remodeled the Farman Company’s twin-engine Goliath biplane and began flying routes across the English Channel between Paris and London. By August 1919, Farman was offering daily service on this route for as many as 14 passengers. To attract passengers, the interior of the fuselage was arranged much like a railway coach. The early burgeoning private services, however, proved not to be financially viable because of high operating costs, high fares, and low passenger turnout. French commercial aviation, like aviation in Britain and Germany, would not have survived without strong support from the government.

The French government took an active role in fostering a domestic commercial aviation industry. French officials believed that aviation would be an important part of the country’s economic growth. They also believed that a strong air presence would extend French political and diplomatic influence to the new postwar world. Passenger comfort was not high on many of these services. As one aviation official noted in a report from 1922, “In some airplanes, the passenger cannot stand conditions for more than two hours.”

The Ford Trimotor 5-AT, nicknamed “The Tin Goose,” was used by almost all the U.S. airlines. Introduced in 1928, these planes could carry 14 or 15 passengers in its corrugated fuselage. It was produced through 1932, but these planes stayed in use much longer. One Trimotor 5-AT, built in 1929, was still being used in Las Vegas for sightseeing in 1991.

The relation of practical experience and conceptual structures

The Archimedes Project, an online library under the auspices of the Max Planck Institute, has made available a searchable database of machine drawings from their digitizing efforts:

The database DMD is part of the research project The Relation of Practical Experience and Conceptual Structures in the Emergence of Science: Mental Models in the History of Mechanics, a project pursued by Department I of the Max Planck Institute for the History of Science (MPIWG), Berlin, headed by Jürgen Renn. In its context, a large number of original sources concerning the history of mechanics have been made available on the Internet as a digital research library, the Archimedes Project. In this broader context the database DMD is especially devoted to studying the practical knowledge of early modern engineers. The aim of the database DMD is the provision of new ways of investigating early modern machine drawings. These documents are important not only for historians of technology but also for historians of science and art and more generally for scholars of Renaissance studies.
