There's a clever way to compare the areas in these figures without using any formulas or calculations at all!

Primes have two positive divisors. Many numbers have more than that. But how many have exactly three?

...or could they be the cause?

In 1959, legendary bongo drummer and physicist Richard Feynman gave a talk called "There's Plenty of Room at the Bottom" which began a race to the nanoscale. But how small is too small?

No one knew how to calculate the value of π, but Archimedes found a way.

Learn how the first color photograph turned red, green, and blue into every color of the rainbow.

In a large grid, many shapes of different sizes are just waiting to be found. But how many of the squares in this grid include the center piece?

Noise-canceling headphones use active noise control to cancel ambient sound. But how could we design a pair for an airplane engineer?

Most of the time, we try to get things correct on purpose. How likely is it to get it right purely by luck?

Sometimes formulas just aren't the most elegant way to solve a problem. In today's geometry problem, we challenge you to compare two areas by cutting shapes into smaller pieces and counting them.

The "magic" of hula-hooping is that nothing appears to be holding the hoop up around your waist. What keeps a hula hoop from falling down?

"Wheel of Fortune" is much more than a gameshow—it's a master class on the intersection of language and computer science.

Although dominoes weren't designed to tile chess boards, they work well for that purpose. It's easy to cover the board when all 64 squares are open, but what about other possibilities?
