Jill Seubert: How a miniaturized atomic clock could revolutionize space exploration

Ask any deep space navigator like Jill Seubert what makes steering a spacecraft difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure. So what do you do when a spacecraft is bad at telling time? You get it a clock -- an atomic clock, to be precise. Let Seubert whisk you away with the ...

Stewart Brand: The Long Now

Stewart Brand works on the Clock of the Long Now, a timepiece that counts down the next 10,000 years. It's a beautiful project that asks us to think about the far, far future. Here, he discusses a tricky side problem with the Clock: Where can we put it?

John Kitching: Who decides how long a second is?

In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how precise are those measurements? And what is that length based on? John Kitching digs into how we scientifically...

Wilton L. Virgo: How does your smartphone know your location?

GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an orbiting satellite that keeps time to the beat of an atomic clock powered by quantum mechanics. [Directed by Nic...

Iseult Gillespie: Why should you read "Midnight's Children"?

It begins with a countdown. A woman goes into labor as the clock ticks towards midnight. Across India, people wait for the declaration of independence after nearly 200 years of British rule. At the stroke of midnight, an infant and two new nations are born in perfect synchronicity. These events form the foundation of "Midnight's Children." Iseul...

Karen J. Meech: The story of 'Oumuamua, the first visitor from another star system

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" -- raised intriguing questions: Was it a chunk of rocky debris from a ...

Sally Kohn: Don't like clickbait? Don't click

Doesn't it seem like a lot of online news sites have moved beyond reporting the news to openly inciting your outrage (and your page views)? News analyst Sally Kohn suggests — don't engage with news that looks like it just wants to make you mad. Instead, give your precious clicks to the news sites you truly trust.

Unusual clocks and the TED2014 talent search event, TED@NYC

Designer Max Schmidt’s Breathing Clock is a fascinating object. It doesn’t have hands -- rather it inflates and deflates to show the progression of time. Schmidt tells PSFK that it’s an homage to the idea that time is relative. This invention reminds us of Scott Thrift, who spoke at last year’s TED@NYC about his seasonal clock. “I feel like e...
