Zubits are designed to make shoe-tying obsolete

The tying and untying of your shoelaces may not be way up there on your list of everyday hassles, but hey – if you can get around doing it, why not? That’s the idea behind Zubits. They’re magnetized shoe closures, that take the place of bows. Each pair of Zubits are initially threaded through the laces of an existing set of shoes. You then knot those laces off to keep them from coming unthreaded, cut off the excess, and then … Continue reading

What Character Was Removed from the Alphabet?


Johnson & Johnson, Barnes & Noble, Dolce & Gabbana: the ampersand today is used primarily in business names, but that small character was once the 27th part of the alphabet. Where did it come from though? The origin of its name is almost as bizarre as the name itself. The shape of the character (&) predates the word ampersand by more than 1,500 years. In the first century, Roman scribes wrote in cursive, so when they wrote the Latin word et … Continue reading

Meet China’s baby-shaped pears and heart-shaped melons


Since the beginnings of agriculture, humans have been customising their fruits and vegetables to suit their needs. Early on, bigger fruits and higher yields were the most important considerations, and while these factors still outweigh the actual taste factor, other, slightly less pressing desires have come into play over the past decade or so. Namely, people want to eat fruit that doesn’t look like regular fruit. Which is how baby-shaped pears have come into existence. Grown by China-based manufacturing company, … Continue reading

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. Numerous special economic … Continue reading

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

European air traffic data visualization

This data visualization was created from real flight data taken from a day in July 2013. It highlights the intensity of the operation in Europe – an operation which runs 24 x 7 x 365. NATS and the UK are at the heart of the operation. With Heathrow as the busiest international airport in Europe, and Gatwick as the busiest single runway airport in the world, we play a key role in ensuring air traffic under our control in European … 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
