What if you put all 7 billion humans into one city, a city as dense as New York, with its towers and skyscrapers? How big would that 7 billion-sized city be? As big as New Jersey? Texas? Bigger? Are cities protecting wild spaces on the planet? We try a little experiment to find out.
Monty Python's John Cleese gives us a highly sophisticated, totally un-understandable, look at the human brain. The secret is, Cleese isn't speaking English. It sounds like English, but its nonsense. The closed caption English translation goes nuts, especially at the very end. It curses!
They call them Romance Pants, from Instructables.com, one of the world's premier do-it-yourself sites. They're for the Romantic Man who has overplanned (and overthought and overdone) his upcoming night of love. One 7805 voltage regulator required.
They're not locusts. They don't eat crops, don't sting babies to death, don't even harm fruit. Yes, they make loud, screechy noises, but if you were a female cicada, you'd find the love songs ... um ... lovely. Here come the cicadas!
You probably know the feeling: You turn on your computer, decide to mosey around, but only for a minute or two, you have important things to do, and then — whooooosh! The computer sucks you in and you can't stop clicking. Why does this happen? Artist Dina Kelberman knows why. Let her trap you.
Some of the best science reporters, like the best Vaudevillians, the best circus performers, the best teachers, are hungry for attention — not for themselves, but for a way to seize your mind, to bring you to an idea, a puzzle, or a creature.
You don't expect fourth-graders to be wise. They're still boys. But one, who was playing and ruminating on his back patio, had a knack for cosmology seemingly well beyond his years.
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.
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.)
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.
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.
Here's something new, exciting and just a little bit troubling: it's a little robot that you can fly with your phone. It's easy. It's versatile. It's got cameras so you can see and record what's going on in the apartments above you, the houses on your block, in backyards, sports fields. Nice, yes. But what happens to privacy if these things become very popular?
The politics of beehives might be able to teach our Congressional leaders a little bit about governing.
