How would you like to get around in a vehicle that “never crashes, that’s at least twice as fast as a plane, that’s solar powered, and that leaves right when you arrive, so there is no waiting for a departure time”? Sounds a little too good to be true, but that is precisely what serial […]

If you were to design a leg for a bipedal animal from scratch, what would it look like? Don’t bother looking down at your own body for inspiration—you won’t find a good model there.  If you want to make a really good bipedal leg, you should make one a lot like an ostrich’s, and nothing like […]

The Sun is one busy celestial body. In addition to giving us light, holding the solar system together, and providing the energy for almost every living thing on Earth, it’s also a grapefruit in a grass field in Austin, Texas, and a 50-foot yellow archway in northern Maine. Now, obviously this huge mass of incandescent gas […]

In Jasper Fforde’s lighthearted “Thursday Next” series of books, people can use a “prose portal” to enter the world of a book, to change the plot or kidnap a character. The prose portal is an imaginative metaphor for a familiar experience: feeling taken away by a narrative, sucked into a good book so that we […]

In the huge range of different human cultural inclinations, one of the most widespread is a fondness for stories. We just love to get lost in a good book or movie. When we do, we tend to ignore where we are and become completely absorbed in the story. Psychologists call this “transportation,” and have conducted […]

Sperm are the cheetahs of the microscopic world: Made of little more than molecular muscle and batteries, tipped with a payload of genetic information, they are optimized for speed. But to orient themselves before their epic, seven-inch sprint (it’s more impressive if you’re less than one three-thousandth that size), they first need to sniff out […]

As astronomers point their telescopes up at the sky to learn about the cosmos, they tend to push those devices’ abilities to their limits. The edge of what we can measure is, of course, where all the interesting things are happening. The downside of this ambition is that the conclusions drawn from the newest data […]

If I told you that I was 99.81 percent certain I had made a big discovery, you might suggest it was time to break out the champagne. If I said the discovery resolved one of the biggest outstanding problems in science and would probably let me punch a ticket to Stockholm to pick up […]

Light was thought to travel through aether like waves on a lakeShutterstock You might know the anecdote. In April 1900, Lord Kelvin, one of the most prominent physicists of the 19th century, stands in the speaker’s well of the Royal Society in London. Surveying the state of scientific knowledge at the dawn of a new […]

In 1972 the Club of Rome, an international think tank, commissioned four scientists to use computers to model the human future. The result was the infamous Limits to Growth that crashed into world culture like an asteroid from space. Collapse, calamity and chaos were the media take-aways from the book, even though the authors tried […]
