The Transport for London tube map, building on Harry Beck's pioneering work in 1931, is rightly hailed as a masterpiece of simplification and clarity in data visualisation. Read the rest
We all know the traditional, navigator-friendly Mercator projection distorts the true sizes of Earth's landmasses. But it's fascinating to see how countries look next to one another when that distortion is, as far as possible, removed. The tininess of Britain against Japan, for example, or the vastness of Alaska against France, become specific in this video from RealLifeLore. As for Greenland... Read the rest
Most states being large and empty, the most frequent answer to the question "what is the most common job in your state?" is "truck driver." For everywhere else, teachers and software developers prevail. And where even roads are rare, farmers. Hawaii, though...
NPR's map is fascinating, though, in that you can jump back to earlier days. In 1978s, what did we all do before software development was the day job of millions?
What's with all the truck drivers? Truck drivers dominate the map for a few reasons.
Driving a truck has been immune to two of the biggest trends affecting U.S. jobs: globalization and automation. A worker in China can't drive a truck in Ohio, and machines can't drive cars (yet).
Let's see about that in a decade. Read the rest
Gonzalo Ciruelos set out to discover which country was the roundest in shape.
We can define roundness in many ways. For example, as you may know, the circle is the shape that given a fixed perimeter maximizes the area. This definition has many problems. One of the problems is that countries generally have chaotic perimeters (also known as borders), so they tend to be much longer than they seem to be.
For that reason, we have to define roundness some other way. We represent countries as a plane region, i.e., a compact set C⊂R2C⊂R2. I will define its roundness as
That's about where I tune out! Turns out the answer is Sierra Leone. Click through to see lots of mathy thingies on the screen, the runners-up, the least round countries, and the source code. Read the rest
Several years ago, a new apartment building went up at 1600 Pennsylvania Avenue SE in Washington DC. That's a few miles from the better known 1600 Pennsylvania Avenue, aka the White House. A car lot was previously on the apartment building property, then registered as 1550 Pennsylvania Avenue SE, but the developers thought it would be a hoot to petition for the 1600 Pennsylvania Avenue SE address. They got it. From WTPO:

Residents say they often get funny looks or disbelief when they have to give their address or hand over their driver’s licenses. Carlos Gutierrez, 39, and other residents said they get asked: “You live at the White House?”
The address has produced headaches for some residents. One early resident of the building, Daniel Perry, 36, said Amazon.com initially wouldn’t take orders to the address, though that’s since been sorted out. Another resident said even now, she sometimes has difficulty ordering online. A recent order for a pair of summer sandals required calling the company, she said.
Residents have to make sure that anyone sending them mail puts the all-important “SE” after the address. The correct zip code — 20003 — is also key. The White House’s ZIP code is 20500.
A goof means the mail might eventually get to the correct recipient, but because the president’s mail gets extra security screening, any resident’s mail with an incomplete address could be significantly delayed.
Mail mix-ups happen the other way, too. Errant letters for the first family arrive at the building every so often and sit unopened by the residents’ mailboxes until the U.S.
Quartermaester is a "speculative" but extremely complete interactive map of Westeros and Essos, the two continents across which Game of Thrones' action sprawls. Character paths and noble constituencies are among the available overlays—surprisingly useful for anyone trying to get the complex series in mental order. Note: it follows the books, not the show.
