There are symbols all around us that we take for granted, like the lightning strike icon, which indicates that something is high voltage. Or a little campfire to indicate that something is flammable. Those icons are pretty obvious, but there are others that aren't so straightforward. Like, why do a triangle and a stick in a circle indicate "peace"? Where does the smiley face actually come from? Or the power symbol? We sent out the 99PI team to dig into the backstory behind some of those images you see every day.

The chili pepper is the pride of New Mexico, but they have a problem with their beloved crop. There just aren’t enough workers to pick the peppers. Picking chili peppers can be especially grueling work even compared to other crops. So most workers are skipping chili harvests in favor of other sources of income.  As a result, small family farms have been planting less and less chili every year in favor of other less-labor intensive crops. So, scientists are trying to find ways to automate the harvest, but picking chilis turned out to be a tough job for a robot. Rose Eveleth’s podcast is called .

A little-known bit of world history about a rag tag group of sailors stranded for years in the Suez Canal at the center of a war.

To help celebrate its 60th anniversary, the Guggenheim Museum teamed up with 99% Invisible to offer visitors a guided audio experience of the museum. Even if you've never been to the Guggenheim Museum, you probably recognize it. From the outside, the building is a light gray spiral, and from the inside, the art is displayed on one long ramp that curves up towards a glass skylight in the ceiling. We’re going to take the greatness of this building as a given. What we’re going to focus on are the oddities, the accretions, the interventions that reveal a different kind of genius. Not just the genius of Frank Lloyd Wright, and his bold, original vision, but the genius of all the people that made this building function, adapt, and grow over the decades.

Before 1992, the easiest way to run the time off the clock in a soccer game was just to pass the ball to the goalkeeper, who could pick the ball up, and hold it for a few seconds before throwing it back into play. This was considered by some to be unsportsmanlike and bad for spectators. So in 1992, the International Football Association Board, the committee in charge of determining the rules of soccer, made a minor change to the laws of the game. From that season forward, in every league throughout the world, when a player passed the ball back to the goalkeeper, the goalkeeper could no longer use their hands. The backpass law didn’t seem like a huge change at the time, but it fundamentally changed soccer.
