    Is Math Discovered or iInvented?

    Would mathematics exist if people didn't? Did we create mathematical concepts to help us understand the world around us, or is math the native language of the universe itself? Jeff Dekofsky traces some famous arguments in this ancient and hotly debated question.

    The Unexpected Math Behind Van Gogh's "Starry Night"

    The Unexpected Math Behind Van Gogh's "Starry Night"

    Physicist Werner Heisenberg said, "When I meet God, I am going to ask him two questions: why relativity? And why turbulence? I really believe he will have an answer for the first." As difficult as turbulence is to understand mathematically, we can use art to depict the way it looks. Natalya St. Clair illustrates how Van Gogh captured this deep mystery of movement, fluid and light in his work.

    How Math Can Prepare New Generations for The Future

    How Math Can Prepare New Generations for The Future

    During the Cold War, Soviet educators were tasked with raising citizens who could out-innovate and out-build their American counterparts. One of their primary tools for doing so? Math. Educator Masha Gershman describes how the adaptive, highly social Soviet approach to teaching math can be deployed to prep new generations for an ever-shifting future.

    This Company Pays Kids To Do Their Math Homework

    Mohamad Jebara loves mathematics -- but he's concerned that too many students grow up thinking that this beautiful, rewarding subject is difficult and boring. His company is experimenting with a bold idea: paying students for completing weekly math homework. He explores the ethics of this model and how it's helping students -- and why learning math is crucial in the era of fake news.

    The Unexpected Math of Origami

    The Unexpected Math of Origami

    Origami, which literally translates to "folding paper," is a Japanese practice dating back to at least the 17th century. In origami, a single, traditionally square sheet of paper can be transformed into almost any shape, purely by folding. The same simple concepts yield everything from a paper crane with about 20 steps, to a dragon with over 1,000 steps. Evan Zodl explores the ancient art form.

    Lessons From Fungi on Markets And Economics

    Lessons From Fungi on Markets And Economics

    Resource inequality is one of our greatest challenges, but it's not unique to humans. Like us, mycorrhizal fungi that live in plant and tree roots strategically trade, steal and withhold resources, displaying remarkable parallels to humans in their capacity to be opportunistic (and sometimes ruthless) -- all in the absence of cognition. In a mind-blowing talk, evolutionary biologist Toby Kiers shares what fungi networks and relationships reveal about human economies, and what they can tell us about inequality.
