East Asia is a crowded place. The crazy-cramped architecture of locales like Hong Kong gives you an idea. But this image posted to Reddit by valeriepieris puts that population consolidation in a whole new light. And for the most part, it seems pretty accurate. Read More >>
When you're flying anywhere you can pretty much turn the whole day into a black hole. The airport/in-flight Wi-Fi wasn't working. We sat at the gate for an hour. We were in a holding pattern. It's great. But sometimes, sometimes you actually want to get where you're going. Read More >>
This board of tiles (or Azulejos, which is a form of Portugese artwork that involves tilework), is making my brain lose its gray matter. The tile board somehow maintains the same number of tiles even when some individual tiles are removed. How did all the tiles fit in the first place? How does it still fit after getting rid of three tiles? Where is the missing square? What sorcery is this? Read More >>

"They're not complete tiles at the end though.
The count isn't really relevant, it's the angles that matter, they leave you with tiles that aren't ..." More »
In the big wide world of mental disorders, synesthesia is probably one of the most interesting and least harmful. It's like a sensory remix. But what's it really like? Alex from Bite Sci-Zed, who "suffers" from a flavour of the disorder where her numerals have very distinct colours, explains it. By the numbers. [Numberphile] Read More >>
When you listen to music, when its waves of sound collide with your ear, you don't hear a wall of sound. A great deal of information might travel in a sound wave and, if that sound wave were actually a giant wave of water rushing onto a beach, you might expect to feel it as a big shove like any other big wave of water coming in from the ocean. Except that's not what happens when this particular wave hits you. Read More >>

If you've ever read the Jurassic Park novel and wondered what those crazy sets of spirals were between chapters, you need to watch this video. Also: if you've never read the Jurassic Park novel, you need to watch this video. Read More >>
If you ever wondered how orange juice can always taste so damn perfect every time you have it, it's because of an algorithm. Coca Cola, which makes Simply Orange and Minute Maid, has an algorithm called the "Black Book" which allows it to standardize Mother Nature. It's crazy. Read More >>

"Every can of Coca Cola OJ tastes the same, this is why. If it weren't for this "secret algorithm" each can would taste different and their customers ..." More »
We're still getting hit by the snow in a lot of the country, fun in the beginning, but you're going to need something to occupy you. Booze is a good start, but the next step is Virtuoso, a music theory board game. Read More >>

Two thousand years ago, wise men of this world weren't lucky enough to have GPS. In the Christmas story, then, the wise men chose to follow a star to navigate their way to Bethlehem—but, scientifically speaking, would that really have worked? Read More >>

Every building material has a theoretical limit which it can't be used beyond: at some point, the weight of material above is enough to crush what's below. Now, a team of engineers has worked out that limit for Lego — and it's surprisingly high. Read More >>
Twenty-seven years after introducing the world's first graphing calculator, Casio has developed its most sophisticated educational Game Boy ever. Indeed, the new Casio fx-CP400's 320 x 528 resolution screen isn't just colour—it's a freaking touchscreen that flips from vertical to horizontal. That's a far cry from the drab 94 x 64 display on the the Casio fx-7000G from 1985. Read More >>
