Given that the builder of the Titanic is said to have famously bragged that his amazing new ship could never be sunk, it's dangerous to argue that an accident like the one that sent the famous vessel to the bottom of the sea 100 years ago could never happen again.

But with the centennial of the April 15, 1912, disaster quickly approaching, there's every indication that modern science and technology in combination with a much greater awareness of seaborne hazards, make such a tragedy -- at least on the scale of Titanic--extremely unlikely today.

It's not, of … Read more

WHITE SANDS MISSILE RANGE -- I recently watched footage of the detonation of the first atomic bomb at Trinity Site in 1945. A black and white mushroom cloud built up in slow motion. Chills and prickles crawled up my spine.

Visiting Trinity Site One week later, I visit ground zero, where a device called "The Gadget" was strapped into a 100-foot-tall steel tower and set off. Two more nuclear explosions took place over Japan after that successful test, harbingers of the end of World War II.

This all happened a long time before I was born, but I feel a strange sadness as I stand here on a hazy spring day in the middle of the Jornada del Muerto, a desert basin full of scrub and pronghorn antelope. That name translates to "day's journey of the dead." … Read more

Yes, New Mexico is one of the 50 states. No, it's not just a big desert. Yes, it's the birthplace of the atomic bomb. No, our cacti don't have surrender arms (that's Arizona). Yes, Microsoft was founded here.

Over the next two weeks, I'm going to cram all my gadgets into a Prius (unfortunately, the DeSoto is in need of radiator repair) and run around the Land of Enchantment, soaking up all the geeky sights I can find.… Read more

You might not think that an iPad could help save whales, but that's just what an app released today is designed to do.

Known as Whale Alert, the iPad app is designed to help ship captains avoid colliding with whales in congested shipping channels.

Specifically, the app, which was created in partnership between the International Fund for Animal Welfare (IFAW), private companies, academia, and the government, is meant to link "the bridge of a ship to the latest data about right whale detections and informs users when their vessels enter right whale management areas."

North Atlantic right … Read more

Did famed filmmaker James Cameron just do for the oceans what scientific experts have struggled to do for decades?

When "Avatar" and "Titanic" director Cameron piloted his custom submersible, the Deepsea Challenger, to the bottom of the Mariana Trench yesterday and became the first person ever to make a solo dive to the world's deepest spot, he shined a crucial spotlight on the field of ocean exploration.

In recent years, scientists have been shouting from rooftops around the world that unless humanity puts more energy into studying our oceans, we are at real risk of … Read more

Everyone likes a good paper airplane. But how much do you love a 45-foot paper airplane?

The answer is clear: A lot.

And your love doesn't have to be unrequited, because the good folks at the Pima Air and Space Museum in Tucson, Ariz., have not only built but also flown a 45-footer, achieving the feat earlier this week. (See video below.)

"It's not every day that a giant paper airplane is released high over the Arizona desert. In fact, it's never been done. But that's exactly what the Pima Air and Space Museum did,&… Read more

For years, Adam Savage and Jamie Hyneman were known for one thing: being the "MythBusters."

But now, the two have launched a new show, Discovery Channel's "Unchained Reaction," "a new six-part series that pits two teams of varying backgrounds against each other to build an elaborate chain-reaction contraption."

Think giant Rube Goldberg machines--balls falling and knocking things into other things. Seesaws going up and throwing things into the air, each step in the process impacting the next, with each team vying to build the most impressive contraption in five tension-packed days. The … Read more

Not long ago, word leaked of a plan that could take anyone with an extra $150 million on a trip around the moon. So SpaceX founder Elon Musk's assertion today that he hopes to be able to take people on a round-trip to Mars for $500,000 signals a much better deal.

Musk told the BBC that he expects to unveil details of his plans sometime later this year or in early 2013. Essentially, though, Musk believes that with its Falcon 9 launcher and Dragon spacecraft, SpaceX may already have the base infrastructure in place that could get paying … Read more

If you're a local fan of digital art, there's a good chance you spent at least part of your weekend at the Creators Project, a celebration of the art form that drew thousands to see a diverse collection of interactive installations here in San Francisco.

From 40-foot-tall latticework cubes filled with LEDs (see video below) to huge triptychs that converted people's body images into flights of fancy, the project showcased some of the best--and worst--digital art around. It also gave visitors access to a collection of films on the topic, and the chance to listen to a number of musicians, including the hit group, the Yeah Yeah Yeahs. … Read more
