Many denizens of the San Francisco Bay Area and Silicon Valley noticed a long series of cloudy numbers in the skies around noon on Wednesday, September 12. No, their coffee wasn't spiked with hallucinogens.

The ephemeral event, known as Pi in the Sky, utilized five aircraft with dot-matrix skywriting technology to write out a thousand numbers of the beloved mathematical constant pi (3.14159..) at a 10,000-foot altitude. If that wasn't impressive enough, the numerals of pi written in the sky each stood nearly a quarter-mile tall, stretched for a 100-mile loop, and undoubtedly caused mass inspiration and confusion all at once. … Read more

SAN FRANCISCO--Building 3D models should be something everyone can do. That's the pitch from ZeroUI, a Silicon Valley startup that has created a technology platform designed to let anyone create their own digital models, whether a robot, drum, table, or anything else.

The Cupertino, Calif., company is relying on gestural input technologies such as Microsoft's Kinect, and soon, Leap Motion's Leap controller, as well as systems built into some computers, to allow users to create their models with nothing but their hands.

The company's name comes from the fact that its system has an extremely minimal user interface. Rather than requiring users to understand the mathematics and physics of a model they might want to build, the ZeroUI system simply allows them to stand in front of the input camera and use intuitive hand gestures to craft their 3D model (see the video below). … Read more

When the Curiosity rover landed on Mars earlier this month, the world couldn't get enough of the six-wheeled dynamo.

Mass adoration for the roving Martian also successfully propelled a pet project by mechanical engineer Stephen Pakbaz, who submitted a miniature version of the Mars Science Laboratory Curiosity rover last November to Cuusoo, a site officially created by Lego that lets fans vote on brick-based concepts (similar to Kickstarter). If a proposition gets 10,000 votes, then "a Lego jury evaluates the idea's feasibility as a product and makes a decision." … Read more

With the Olympics still in midstride, and with the arrival of the always exciting NFL exhibition games, you might perhaps have missed that a spacecraft landed on Mars a few days ago to express our human curiosity.

President Obama, however, has made it very clear that, should little beings be found out there, they will immediately become his top priority.

Indeed, in a phone call today with the Curiosity team, the President revealed that the first question he is being asked about the mission is whether Martians have already been found.

One can imagine that, even if they had been … Read more

SAN DIEGO -- For hundreds of thousands of passionate panda watchers, the birth at the San Diego Zoo today of a new panda cub is an event well worth celebrating, especially given that the mother is probably the second-oldest known panda ever to successfully deliver. And thanks to some high-tech imaging, the zoo was able to monitor the pregnancy every step of the way.

For weeks, the panda team at the zoo here has been on tenterhooks, hoping against hope that the 20-year-old mother, Bai Yun, would carry to term what they were nearly certain was a healthy cub. But … Read more

MOJAVE DESERT, Calif.--It's hard to imagine a more complete -- and impressive -- collection of aviation facilities and aircraft anywhere on the planet than the one in this vast, arid, wide-open wasteland northeast of Los Angeles.

Thanks to its endless amounts of dry, flat terrain, useless to most people, and the fact that there are only a few ways in -- vital for security -- the Mojave is, and has long been, the beating heart of the aviation world. It's here that Chuck Yeager first broke the sound barrier. And where Burt Rutan's SpaceShipOne ushered in … Read more

LOS ANGELES -- Walking through gallery after gallery of classical European paintings, sculptures, and other antiquities at the J. Paul Getty Museum here, it's easy to get lost in the history and beauty of the often centuries-old art. Especially if you're toting today's latest mobile technology.

Home to some of the most celebrated European artwork in the world -- and one of the most visited museums in the United States -- the Getty has also become one of the museums most devoted to adopting technology aimed at enhancing guests' experience, as well as at using high-tech tools … Read more

LA JOLLA, Calif. -- If you want to know how U.S. Marines stationed deep in the desert of Afghanistan get highly accurate real-time weather reports, you have only to look to this stunning seaside town and some of its leading ocean scientists.

What started as a Marine's random comment about needing better weather forecasting because of the dangers of flying in extreme desert conditions quickly led to the development of a tool that can be set up just about anywhere by a couple of Marines in minutes. … Read more

PALOMAR MOUNTAIN, Calif.--If you want to talk big scientific breakthroughs, how about quasars and supernovae?

Those are just two of the most important discoveries in the long, very storied history of the Palomar Observatory, a set of telescopes and other astronomical instruments located at the top of this mountain northeast of San Diego. And while the facility no longer holds quite the place in the astronomy community that it once had, for most of the second half of the 20th century, it was the undisputed champion of the world.

Topping the bill at Palomar is its groundbreaking 200-inch Hale Telescope. … Read more
