Sandy Island, located in the Pacific Ocean off the coast of Australia, occupies about about 45 square miles of the Coral Sea. It was documented in 1772 and appeared on a 1908 admiralty chart and in Google Maps. The problem is, Sandy Island never existed.
Today is March 14, or "3/14," the first three digits of Pi. It's a day celebrated around the (geek) world as "Pi Day." So here's the pie version of Pi, the down, dirty and baked goods approach, illustrated by Brady Haran, a video journalist who loves numbers.
Human history (the written-down part) began about 7,000 years ago. Here's everything we've learned in all that time, compressed into five words, spoken by a puzzled human — from a wonderfully clever Los Angeles cartoonist named Reza.
Lurking in the ground beneath our feet, waiting in their burrows for the first signs of spring are tens of millions of cicadas.
After 17 years, cicadas are expected to emerge and overwhelm a large swath of land from Virginia to Connecticut — climbing up trees, flying in swarms and blanketing grassy areas so they crunch underfoot.
What are you doing this weekend? Bet you're not using scraps from an old Toshiba TV to melt stacks of metal coins into steaming-hot foam. No? I thought not. (But we are.)
Run, cheetah, run... a paradoxically fast and slow cat has caught Andy Mills' attention...
It's already happened. We humans have already met an intelligent alien. Not only that, we almost certainly had sex with them. And we did here, right here on Earth, not so many generations ago.
What happened to the future? In the '60s and '70s, says astrophysicist Neil Tyson, kids thought about going to space, exploring; tomorrow seemed so, so near. But no longer. Our world these days, is tighter, more awake to limits, and that's not good, says Tyson, not good for kids, and especially not good for the economy. Tyson insists that dreaming makes us richer.
Mums bloom in the fall, daffodils in spring, roses in summer. How do farmers get such different plants to bloom simultaneously in Winter for Valentine's Day? It's done, strangely, with short, sudden flashes of light.
A new video technology that amplifies small color changes and slight movements can, when pointed at people, tell what's going on inside.
Banishments are much more complicated than they used to be. And this "Minute Physics" video suggests, paradoxically, that both you and the person you banish are somehow simultaneously at the center of the universe.
If DNA molecules are the Marilyn Monroes of biochemistry — everybody knows what DNA looks like — what about proteins? Why do most people have no idea what a protein looks like? Well, maybe this will help: proteins that look like houseflies, Bedouins, bumblebees and a pair that look uncannily like Moses and the Burning Bush.
Something amazing is about to happen: you can claim a little piece of history by naming our long-lost common ancestor. We're not kidding -- the scientists who discovered the creature want your help, so we're holding a contest. Go!
Normally a plate can't get a job at the circus. It's just a plate. But here's a plate that can swoop through the air, catch a flying pole, and balance it upright, midair! In other words, a circus-worthy plate. Artificial Intelligence is the science of making dumb things do smart-looking stuff.
