Mathematics. A mathematician emerges from a cave, hands you the slip of paper below, and says "If x² + y² = 1, what is the minimum value of x + y?" What is your response?

Matrix multiplication is not easy to understand. Even looking at the definition used to make me sweat, let alone trying to comprehend the pattern. Yet, there is a stunningly simple explanation behind it. Let's pull back the curtain!

Consider N runners on a circular track of length L. They start from the same spot and run at constant, distinct speeds. A runner is "lonely" if the distance from everyone else is at least L/N Lonely Runner Conjecture: Each runner is lonely at some time It's unsolved for N > 7

Mathematics. Assume all lines are straight, and all angles are right angles. Do we have enough information to determine the value of the perimeter of the shape? If so, what is it? Miss Miniver's question for young students.

Map of Mathematics. Enlarge the figure to see all the wonderful areas for exploration and imagination. Which topic might you find most fascinating? By Dominic Walliman, @DominicWalliman, Source: bit.ly/3TdnwcS, Used with permission.

Where in the world is von Kármán—San Diego? 🤓 Nope! von Kármán vortices often swirl in certain parts of the world more than others, though. Take a look at more, with this week's #EarthFromOrbit: go.usa.gov/xH64k

Look closely. There are actually 16 circles in this image. And once you see them, the image appears changed forever. The wonderful coffer illusion, by Anthony Norcia

This is a mathematics joke.
