  • How are Fibonacci numbers expressed in nature?
    How are Fibonacci numbers expressed in nature?

    Is there a magic equation to the universe? Probably not. But thanks to one man's obsession with rabbits, we have a sequence of numbers that reflect various patterns found in nature. See more »

    How Chaos Theory Works

    Has this ever happened to you? The meteorologist calls for a massive snowstorm, but the flakes fail to arrive. Chaos theory can shed light on why forecasts fail (and why our orderly world may not be so orderly after all). See more »

    How Fractals Work

    Fractals have been around forever but were only defined in the last quarter of the 20th century. Think you can wrap your brain around how fractals work? See more »

  • How Math Works
    How Math Works

    A world without math is unimaginable. It's a part of who we are. It's the analytical juice of our left brain. In the words of physicist Richard Feynman, even a fool can use it. So why do so many of us turn our backs on numbers? See more »

  • How Pi Works
    How Pi Works

    Pi is an extremely interesting number that is important to all sorts of mathematical calculations. Did you know it can be calculated without the use of circles? Find out how you can calculate it yourself. See more »

  • How Tessellations Work
    How Tessellations Work

    Mathematics achieves the sublime. Sometimes, as with tessellations, it rises to art. In their simplest form, tessellations consist of a single shape that repeats over a two-dimensional plane without any gaps. Why was M.C. Escher so fixated on them? See more »

  • How Zero Works
    How Zero Works

    You use the number zero all the time, but it may surprise you to learn that it sometimes isn't a number at all. It may surprise you even more to learn that it was all but invented. See what else surprises you about zero in this article. See more »

    Quiz: Tessellate This!

    Tessellations pop up everywhere once you know what you're looking for. You can find them under microscopes, radiating from sunflowers and even in the hallowed halls of art museums. What can you tell us about these awesome repeating patterns? See more »

  • What is number theory?
    What is number theory?

    For many of us, a number is just a number, a bit of information that tells you, say, what time it is. But mathematicians look at that same number and divine relationships that underlie nature itself. Ready to enter the trippy world of number theory? See more »
