New App Teaches Users How to Survive Plane Crash

Plane crashes are very rare—in fact, Americans would need to take an average of one flight a day for 55,000 years before being involved in a fatal one, according to one MIT statistician—but it can't hurt to plan for one. Prepare for Impact, a new 3D mobile app, details what to do when something goes terribly wrong on a flight and how to survive a crash.

The app features several nightmarish in-flight scenarios, from minor incidents like runway overruns to extreme cases such as a fiery crash into water. It also includes instructions for how to handle in-flight decompression, unusable exits, and minor fires.

Researchers and engineers from the Human-Computer Interaction Lab at the University of Udine, Italy designed Prepare For Impact as a first-person decision-based simulator with consequences for every action you take. “People can familiarize themselves with aircraft emergencies by playing ‘what-if’ scenarios, choosing their own actions, and seeing their positive or negative consequences realistically depicted by a 3D game,” professor Luca Chittaro said in a press release.

Prepare For Impact is available for Android and iOS devices

Monthly Internet Costs in Every Country

Thanks to the internet, people around the world can conduct global research, trade tips, and find faraway friends without ever leaving their couch. Not everyone pays the same price for these digital privileges, though, according to new data visualizations spotted by Thrillist.

To compare internet user prices in each country, cost information site HowMuch.net created a series of maps. The data comes courtesy of English market research consultancy BDRC and Cable.co.uk, which teamed up to analyze 3351 broadband packages in 196 nations between August 18, 2017 and October 12, 2017.

In the U.S., for example, the average cost for internet service is $66 per month. That’s substantially more than what browsers pay in neighboring Mexico ($27) and Canada ($55). Still, we don’t have it bad compared to either Namibia or Burkina Faso, where users shell out a staggering $464 and $924, respectively, for monthly broadband access. In fact, internet in the U.S. is far cheaper than what residents in 113 countries pay, including those in Saudi Arabia ($84), Indonesia ($72), and Greenland ($84).

On average, internet costs in Asia and Russia tend to be among the lowest, while access is prohibitively expensive in sub-Saharan Africa and in certain parts of Oceania. As for the world’s cheapest internet, you’ll find it in Ukraine and Iran.

Can You Figure Out Why the Turtles Bulge in This Optical Illusion?

Ready for a little vision test? Akiyoshi Kitaoka, a Kyoto-based psychologist who studies visual illusions, created this eye-bending image that appears to bulge and bend. In the image, shared on Syfy.com, the horizontal and vertical lines actually run straight across and down, but they look like they ripple, and the shapes (Kitaoka calls them turtles) look like they’re different shades of gray, even though they’re an identical color.

As Phil Plait explains for Syfy, the key is in the corners—the turtle “legs,” if you will. “At each vertex between turtles, they form a rotated square divided into four smaller squares," he writes. "Note how they're offset from one another, giving a twist to the vertices.” If you zoom in closely on the image, the lines begin to straighten out.

The difference in the colors, meanwhile, is a result of the contrast between the black and white pixels outlining the turtles. If the outlines of the turtles were entirely black or entirely white, instead of a combination, the grays would look identical. But the contrast between the two fools your eyes into thinking they're different.
