Many people hope humans will eventually walk on Mars. But there's a lot to sort out before that can happen, including this question: how does the way we tell time change when we have humans on more than one planet?
Most years February is 28 days long. Every fourth year it has 29. But one time, in one country, for one year, there was a February 30th.
Our last show of the year is about the Plock, a very unique clock that doesn’t so much tell the time as it writes the time out.
Time is a funny thing, and measuring time can get pretty wild too. The proof is a study out of the UK that finds clocks that use more energy, and give off more heat, are also more accurate. Plus: a book of photos by Rumi Ando showcases Tokyo, but with its signs, cables, doors and windows removed.
Fifteen people just took part in the Deep Time project, where they lived in a cave in France as far away from time as we can get. And some interesting things happened. Plus: scientists in Brazil have just spotted a pumpkin toadlet, a tiny orange amphibian that glows green under ultraviolet light.
A new study from researchers at Aoyama Gakuin University and Osaka University finds that something interesting happens when we’re trying not to reveal something: our perception of time slows down. Plus: MIT physicists have designed a model for a super-accurate atomic clock that even accounts for quantum physics.
The strangeness of this year has been messing with our internal clocks and our sense of how days, weeks and months go. But sometimes it's good to rethink how we understand time, like though Tahoe Timescape, a project to take photographs over one thousand years. Plus: New York City is where King Kong ran wild in the movies, but a new statue could help rebuild the relationship between NYC and big apes.
Time is an odd thing no matter where you are, but it's especially weird at the North and South Poles, since all the world's time zones sort of converge there and a day as we know it lasts an entire year. Plus: it may be time to pay a visit to the World's Largest Buffalo Monument!
November 18, 1883 is when railroads across the United States adopted a uniform system of time, more or less getting all of us in sync with each other. But what was time like before then? Plus: Japan has had cat cafes, hedgehog cafes and bunny cafes. Now there's a minipig cafe!
A project to build a clock that will run for 10,000 years got us thinking about how we measure time - and amazingly, 10,000 years is more time than has passed since the invention of hours, minutes and seconds.
