Enter Pyongyang

“Enter Pyongyang” is another stunning collaboration between city-­branding pioneer JT Singh and flow-motion videographer Rob Whitworth. Blending time-lapse photography, acceleration and slow motion, HD and digital animation, they have produced a cutting‐edge panorama of a city hardly known, but one emerging on the visitor’s landscape as North Korea’s opening unfolds. North Korea was the last country seemingly immune to change—but no longer. Recent years have witnessed mobile phone penetration, a surge in tourists, and even a marathon.

If you fold a piece of paper in half a 103 times it is as thick as the Universe


Folding paper in half over and over again is a whole lot harder than it sounds. The current record is 12 times, performed over a decade ago by American high school student, Britney Gallivan. Before she managed her twelfth fold, the record was just seven folds, and it was believed to be mathematically impossible to get any higher than that. The phenomenon is based on the exponential growth of the thickness of a sheet of paper when it’s folded in … Continue reading

These New Smart Bricks Are Like Lego for Real Buildings

If these lumps of concrete look familiar, that’s because they take some of their inspiration from Lego—but there’s more to them than child’s play. Created by a company called Kite Bricks, the blocks are actually referred to as Smart Brick, or S-Bricks to their chums. They come in a range of shapes and sizes, but all feature rows of knobs along their tops which slot into voids at the bottom of others. They’re fastened together with special adhesive, rather than … Continue reading

Snell’s Window

snells window

Snell’s window is a phenomenon by which an underwater viewer sees everything above the surface through a cone of light of width of about 96 degrees. This phenomenon is caused by refraction of light entering water, and is governed by Snell’s Law. The area outside Snell’s window will either be completely dark or show a reflection of underwater objects. Underwater photographers sometimes compose photographs from below such that their subjects fall inside Snell’s window, which backlights and focuses attention on … Continue reading

2014 World Cup ball has better aerodynamics: NASA


The official 2014 World Cup game ball should make players happy, NASA said after its own aerodynamics testing showed the new design avoided the pitfalls of the unpopular 2010 version. Players complained the official Jabulani ball from four years ago was too unpredictable—a result of the almost perfectly smooth design, which meant that the airflow over the ball pulled it in unpredictable directions. Although some strikers were able to take advantage of the trait, the erratic trajectory drew complaints from … Continue reading

30,000 LED Lights Make The Trams In Budapest Look Like Time Machines

Most major cities magically light up during the holiday season, and the Hungarian capital of Budapest is no different. Every winter, this city is covered in festive holiday decorations, but one of the most interesting of these are the city’s trams, which are covered in 30,000 bright blinking LED lights. The lights themselves might be of no particular interest – it’s what photographers can do with them that is really cool. With a long exposure photo, these trams transform into … Continue reading

How to win at rock-paper-scissors

What are your odds of winning rock-paper-scissors? Simple – one in three. At least, that’s what chance predicts. But people do not play randomly – they follow hidden patterns that you can predict to win more games than you should, a study has revealed. Winners tend to stick with their winning action, while losers tend to switch to the next action in the sequence “rock-paper-scissors”. Anticipating these moves could give you a winning edge, say scientists. Their strategy was revealed … Continue reading

Did removing lead from petrol spark a decline in crime?

Many Western nations have experienced significant declines in crime in recent decades, but could the removal of lead from petrol explain that? Working away in his laboratory in 1921, Thomas Midgley wanted to fuel a brighter tomorrow. He created tetraethyl lead – a compound that would make car engines more efficient than ever. But did the lead that we added to our petrol do something so much worse? Was it the cause of a decades-long crime wave that is only … Continue reading

Euro leading to uniform prices across countries

Economics has a “law of one price,” which states that identical goods should, in theory, sell for identical prices—or else markets will even out the differences. Empirical work on the topic, however, has produced little evidence in support of this “law,” and many studies showing deviations from it. Now a newly published paper co-authored by two MIT economists, along with a colleague from the University of Chicago, presents evidence of a strong convergence of prices within the Eurozone, the region of … Continue reading
