We don't have too many cameras out there in space past the moon, which is why most of our space shots are either looking outward, such as the shots taken by Hubble, or taken of Earth from the moon or closer. Which is why this video is so astounding. It's a video of the moon passing directly in front of the Earth, taken by NASA's EPOXI spacecraft from a whopping 31 million miles away.

The quality isn't the best, but it doesn't need to be; it's still absolutely breathtaking. This is an alien's-eye view, my friends, seen for the very first time. Amazing.

Asteroid 2007 TU24, discovered by the Catalina Sky Survey on October 11, 2007 will closely approach the Earth to within 1.4 lunar distances (334,000 miles) on 2008 Jan. 29 08:33 UT. This object, between 150 and 600 meters in diameter, will reach an approximate apparent magnitude 10.3 on Jan. 29-30 before quickly becoming fainter as it moves further from Earth. For a brief time the asteroid will be observable in dark and clear skies with amateur telescopes of 3 inch apertures or larger.

For an interactive illustration of this object's orbit see:

http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2007+TU24&orb=1

The illustration below is courtesy of amateur astronomer Dr. Dale Ireland from Silverdale, WA. The illustration shows the asteroid's track on the sky for 3 days near the time of the close Earth approach as seen from the city of Philadelphia. Since the object's parallax will be a significant fraction of a degree, observers are encouraged to use our on-line Horizons ephemeris generation service for their specific locations. These personalized ephemeris tables can be generated at: http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=2007%20TU24

Given the estimated number of near-Earth asteroids of this size (about 7,000 discovered and undiscovered objects), an object of this size would be expected to pass this close to Earth, on average, about every 5 years or so. The average interval between actual Earth impacts for an object of this size would be about 37,000 years. For the January 29th encounter, near Earth asteroid 2007 TU24 has no chance of hitting, or affecting, Earth.

2007 TU24 will be the closest currently known approach by a potentially hazardous asteroid of this size or larger until 2027. Plans have been made for the Goldstone planetary radar to observe this object Jan 23-24 and for the Arecibo radar to observe it Jan 27-28 and then Feb 1-4. High resolution radar imaging is expected, which may permit later 3-D shape reconstruction.

Movie characters from the Terminator to the Bionic Woman use bionic eyes to zoom in on far-off scenes, have useful facts pop into their field of view, or create virtual crosshairs. Off the screen, virtual displays have been proposed for more practical purposes -- visual aids to help vision-impaired people, holographic driving control panels and even as a way to surf the Web on the go.

Contact lenses with metal connectors for electronic circuits were safely worn by rabbits in lab tests.

The device to make this happen may be familiar. Engineers at the University of Washington have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.

"Looking through a completed lens, you would see what the display is generating superimposed on the world outside," said Babak Parviz, a UW assistant professor of electrical engineering. "This is a very small step toward that goal, but I think it's extremely promising." The results were presented today at the Institute of Electrical and Electronics Engineers' international conference on Micro Electro Mechanical Systems by Harvey Ho, a former graduate student of Parviz's now working at Sandia National Laboratories in Livermore, Calif. Other co-authors are Ehsan Saeedi and Samuel Kim in the UW's electrical engineering department and Tueng Shen in the UW Medical Center's ophthalmology department.

There are many possible uses for virtual displays. Drivers or pilots could see a vehicle's speed projected onto the windshield. Video-game companies could use the contact lenses to completely immerse players in a virtual world without restricting their range of motion. And for communications, people on the go could surf the Internet on a midair virtual display screen that only they would be able to see.

"People may find all sorts of applications for it that we have not thought about. Our goal is to demonstrate the basic technology and make sure it works and that it's safe," said Parviz, who heads a multi-disciplinary UW group that is developing electronics for contact lenses.

A researcher holds one of the completed lenses.

The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The lenses were tested on rabbits for up to 20 minutes and the animals showed no adverse effects.

Ideally, installing or removing the bionic eye would be as easy as popping a contact lens in or out, and once installed the wearer would barely know the gadget was there, Parviz said.

Building the lenses was a challenge because materials that are safe for use in the body, such as the flexible organic materials used in contact lenses, are delicate. Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes one third of a millimeter across. They then sprinkled the grayish powder of electrical components onto a sheet of flexible plastic. The shape of each tiny component dictates which piece it can attach to, a microfabrication technique known as self-assembly. Capillary forces -- the same type of forces that make water move up a plant's roots, and that cause the edge of a glass of water to curve upward -- pull the pieces into position.

The prototype contact lens does not correct the wearer's vision, but the technique could be used on a corrective lens, Parviz said. And all the gadgetry won't obstruct a person's view.

"There is a large area outside of the transparent part of the eye that we can use for placing instrumentation," Parviz said. Future improvements will add wireless communication to and from the lens. The researchers hope to power the whole system using a combination of radio-frequency power and solar cells placed on the lens, Parviz said.

A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational "fairly quickly," according to Parviz.

The research was funded by the National Science Foundation and a Technology Gap Innovation Fund from the University of Washington.

The Right Brain vs Left Brain test ... do you see the dancer turning clockwise or anti-clockwise?

If clockwise, then you use more of the right side of the brain and vice versa.
Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.

According to Gates, there are currently six trends, which will be determining Microsoft and its product strategy for the years to come. In a rather unusual way, he mentioned the dramatic changes in the way the hardware engines that will be fueling new applications are engineered.

The fact that performance advances have shifted from a pure increase of clock speed to increased parallelism was described by Gates as a "challenge". He believes that "parallel execution will be the primary way silicon power will be delivered" down the road and not so much the fact that there is more clock speed available. According to Gates, microprocessors will get to 10 GHz, "but not much further" (...) "even 5 to 6 years out."

Playing in two dimensions is easy enough, but what truly separates the men from the boys? Maybe it’s when you give up your easel for a tool belt and get to work with a hammer and chisel. These amazing sculptors took their talents 3-D.

1. Donatello (1386? - 1466)

Unquestionably the greatest sculptor of the early Renaissance, Donatello [wiki] was born in Florence, though he traveled widely and was famous throughout Italy. Donatello had complete mastery of bronze, stone, wood, and terra cotta, and nothing escaped his extraordinary capabilities: relief sculpture, nudes, equestrian statues, groups of figures, and single figures seated or standing. In fact, he reinvented the art of sculpture just as other contemporaries were reinventing the art of painting, and his innovations and discoveries were profoundly influential. Above all, Donatello seemed to be able to bring sculpture to life by his ability to tell a story, combine realism and powerful emotion, and create the impression that his figures were more than mere objects of beauty for passive contemplation, but creations filled with energy and thought, ready to spring into action.

2. Michelangelo (1475 - 1564)

Michelangelo’s David

Michelangelo’s Pietà

Clearly an outstanding genius, Michelangelo’s [wiki] influence dominated European art until Picasso changed the rules. A sculptor first, painter and architect second, Michelangelo was a workaholic - a melancholic, temperamental, and lonely figure. He had a profound belief in the human form (especially the male nude) as the ultimate expression of human spirituality, sensibility, and beauty. In fact, Michelangelo’s early work shows the human being as the measure of all things: idealized, muscular, confident, and quasi-divine. Gradually that image becomes more expressive, more human, less perfect, fallible, and flawed. He loved turning and twisting poses full of latent energy, and faces that expressed the full range of human emotion. Endlessly inventive, he never repeated a pose, although being a true Renaissance man, he was proud to borrow from Greek and Roman precedents.

3. Gian Lorenzo Bernini (1598 - 1680)

Bernini’s Apollo and Daphne

Bernini’s Rape of Proserpina

Bernini’s David

Bernini [wiki] set sculpture free from its previous occupation with earthly gravity and intellectual emotion, allowing it to discover a new freedom that permitted it to move, soar, and have a visionary and theatrical quality. A child prodigy, Bernini had a sparkling personality and brilliant wit (he wrote comedies) - qualities that shine through his sculptures. He was also a true visionary technically, able to carve marble so as to make it seem to move or have the delicacy of the finest lace. At his best he blends sculpture, architecture, and painting into an extravagant theatrical ensemble, especially in his fountains, where the play of water and light over his larger-than-life human figures and animals creates a vision that is literally out of this world.

4. Auguste Rodin (1840 - 1917)

Rodin [wiki] is the glorious, triumphant finale to the sculptural tradition that starts with Donatello. He is rightly spoken of in the same breath as Michelangelo, although they’re very different: Michelangelo carved into marble whereas Rodin molded with clay. A shy workaholic, untidy, and physically enormous, Rodin emerged from impoverished beginnings. He became an international celebrity and was deeply attractive to smart women. Rodin was also well known for loving the fluidity of clay and plaster, and was able to retain this quality even when his work was cast in bronze, thereby magically releasing in his figures an extraordinary range of human feelings and a sense of the unknown forces of nature.

5. Constantin Brancusi (1876 - 1957)

Brancusi’s The Kiss

Brancusi’s The Endless Column

Brancusi [wiki] is one of the seminal figures of 20th-century art with a profound influence on sculpture and design. Born into a Romanian peasant family, he settled in Paris in 1904, becoming a student of Rodin. Amazingly, Brancusi remained indifferent to honor and fame. At the heart of his work is a tireless refinement and search for purity. Never abstract, his work always references something recognizable in nature. Brancusi believed in the maxim "Truth to materials," and he always brought out the inherent quality of each material that he used. The purity and simplicity of his form touch something very basic in the human psyche, just as does, for example, the sound of the waves of the sea.

Die mit vielen Vorschusslorbeeren bedachten "serviceorientierten Architekturen", die in der IT eine neue Managementstruktur widerspiegeln sollen, funktionieren oft nicht, ergab eine Untersuchung der britischen Marktforscher.

Zwar werden service-orientierte Architekturen (SOA) in den nächsten fünf Jahren massiv verändern, wie IT-Abteilung und Unternehmen zusammenarbeiten, stellt die Butler Group in ihrer neuen Studie "Planning and Implementing SOA" fest. Doch die wenigen Unternehmen, die bereits Tests mit der SOA durchführten, neigten dazu, erst die internen Geschäftsprozesse umzugestalten und dann erst die IT in den betroffenen Bereichen anzupassen.

Mike Thompson, Co-Autor der Studie: "Viele konzentrieren sich auf die Technik, die direkt mit einer SOA verbunden ist, aber beschäftigen sich nicht mit der, die die Geschäftsprozesse steuern soll". Ein Mangel an Expertise im eigenen Haus und ungenügender Festlegung, wer wie mitreden will, führe zu Problemen beim Datenmanagement, der Performance, Sicherheit und der Dienste-Verfügbarkeit.

Nur etwa 8 Prozent der befragten 80 IT-Manager größerer Unternehmen hat bereits eine SOA installiert, 17 Prozent beschäftigten sich mit Versuchen, und 36 Prozent überprüften noch, ob SOA überhaupt in Frage kommt.

Fazit der Studie ist, nicht gleich alles umzukrempeln, sondern mit einem konkreten Geschäftsproblem zu beginnen, daraus zu lernen und anhand dieser Erfahrungen vom Kleinen zum Großen zu gelangen. Das Inhaltsvezeichnis der Studie mit wertvollen Tipps für Unternehmen, die SOA einführen wollen, stellt Butler als PDF online. Die komplette Studie ist kostenpflichtig erhältlich.

Rob Levy, Cheftechniker beim Unternehmens-Software-Anbieter BEA Systems, bekräftigt diese Erfahrungen gegenüber VNU: "Das A in SOA sollte man nicht als 'Architecture', sondern als 'Attitude' sehen." Nicht umsonst ist der Amerikaner darauf versessen, nutzerfreundliche Web-2.0-Techniken in seine Infrastrukturlösungen zu integrieren, die hinter der SOA stehen. Levy: "Auch Firmen werden künftig mehr von unten gesteuert und nicht mehr nur von einem Ober-Zampano, der allen anderen erklärt, wie sie zu arbeiten haben". Entsprechend solle auch an die Implementierung von SOA-Software herangegangen werden.

Moving with the stealth and style of a startup, mighty Microsoft Corp. today has released a point-and-click software tool designed to make it easier to program simple robots.

[QUOTE]
REDMOND, Wash. — Dec. 12, 2006 — Among the many remarkable innovations emerging out of the robotics industry, from surveillance robots that can defuse roadside bombs to robotic arms that perform surgeries, one persistent challenge has been the lack of a common development platform that would allow developers to easily create robotic applications for varied hardware platforms. Today, Microsoft Corp. is closing this gap with the release of Microsoft^® Robotics Studio, a new Windows^®-based development environment for creating robotic software for a wide variety of hardware platforms. Microsoft also introduced a new third-party partner program featuring Microsoft Robotics Studio-enabled applications, services and robots from independent software vendors, service providers, hardware component vendors and robot manufacturers. Already more than 30 third-party companies have pledged support for the new robotics development and runtime platform, which is available for download and evaluation at http://microsoft.com/robotics.
