Would it surprise you to learn that fish and birds count in pretty much the same way that we do? And that infants can do math? Our animal brains deal with quantities in very specific ways, from quick counts of a few dots to how we...

Since taking office in January, the Trump administration has moved to cancel or freeze trillions in federal funding. That includes billions in funding from the U.S. Department of Agriculture. William Brangham reports on how the funding...

Lots of languages and species are going extinct, but because others keep getting found or described, the official counts of languages and species are still increasing.

There’s an island in the Caribbean where David used to perform magic tricks for monkeys. And it was super cool because it suggested that they have the ability to count! (but only up to four)

You would think that almost everyone has the same exact number of bones in their body, but that number is different, and changing, in everyone!

Moser's circle problem, and its solution.

What exactly are fractals? A common misconception is that they are shapes which look exactly like themselves when you zoom in. In fact, the definition has something to do with the idea of "fractal dimension".

Imagine we want to build a new space port at one of four recently settled Martian bases, and are holding a vote to choose its location. Of the 100 colonists on Mars, 42 live on West Base, 26 on North Base, 15 on South Base, and 17 on...

How couting in binary can solve the famous tower's of hanoi problem.

The enigmatic equation e^{pi i} = -1 is usually explained using Taylor's formula during a calculus class. This video offers a different perspective, which involves thinking about numbers as actions, and about e^x as something which turns...

How couting in binary can solve the famous tower's of hanoi problem.

Though the first written number system can be dated back to 2500 years ago in Mesopotamia, a zero-like symbol did not appear until 7th century CE India. Jessica Oreck and Rachael Teel track the evolution of zero from a dot to the symbol...

It seems silly to ask if plants can count, but even the New York Times has called Venus flytraps 'Plants That Can Count.' Is counting a thing plants can do?

How high can you count on your fingers? It seems like a question with an obvious answer. After all, most of us have ten fingers -- or to be more precise, eight fingers and two thumbs. This gives us a total of ten digits on our two hands,...

You've found Leonardo da Vinci's secret vault, secured by a series of combination locks. Fortunately, your treasure map has three codes: 1210, 3211000, and. . . hmm. The last one appears to be missing. Can you figure out the last number...

Did you know you can read the story of a tree's life? By looking at a tree's rings, you can figure out way more than just how old it is! Jessi and Squeaks are here to show you what to look for next time you're on a hike and find a tree...
