What color is a mirror? Go ahead. Guess.

YouTuber vsauce’s latest video is all about the color of mirrors and how you only think you know what color a mirror is.

Here it is, the first image sent from the surface of Mars from the Curiosity rover
It’s the shadow of the rover across the surface of the red planet. The original image size first came in at just 64x64.

Russian satellite’s 121-megapixel image of Earth is most detailed yet
There’s been a long history of NASA-provided “Blue Marble” images of Earth, but now we’re getting a different perspective thanks to photos taken by the Elektro-L No.1 Russian weather satellite. Unlike NASA’s images, this satellite produces 121-megapixel images that capture the Earth in one shot instead of a collection of pictures from multiple flybys stitched together. The result is an image that’s the highest-resolution image of Earth yet.

The Candle Problem
Given a book of matches, a box of thumbtacks, and a candle, how can you fix the candle to the wall so that its wax won’t drip onto the table below?
See Answer Below



Pin the box to the wall, put the candle in the box, and light it.
In experiments, Gestalt psychologist Karl Duncker found that most subjects instead tried to pin the candle directly to the wall or to use melted wax to affix it there (neither worked). Duncker called this “functional fixedness” — a “mental block against using an object in a new way that is required to solve a problem.” In this case, subjects had “fixated” on the box’s function as a container, which prevented them from considering it as a platform. If the box was empty at the start of the experiment, they were more likely to find the correct solution.
In a 2000 study, psychologists Tim German and Margaret Defeyter found the 6- and 7-year-olds show signs of functional fixedness, but 5-year-olds appear immune to it: “Rather than taking into account only the properfunction of an object, they adopt and agents-goals view of function in which any intentional use of an object can be its function.”

The most gorgeous photo of Saturn’s moon Enceladus yet
Taken in January of last year, this is probably the best image you’ll ever see of Enceladus, not just because of the detail, but because the moon was positioned just so that Saturn gave it just enough shadow to provide detail. Normally, the icy moon of Enceladus would be bright white.
