1. Math

    Math explains why dense crowds form surprisingly orderly lines

    New research into the behavior of moving groups of people adds to decades of study on the wisdom of crowds.

  2. Math

    Scientists Say: Parabola

    A parabola is a U-shaped curve, where every point along that curve is the same distance from another point and a line.

  3. Math

    Scientists Say: Ellipse

    Ellipse describes the shapes of planetary orbits around their stars and explains the wacky acoustic phenomenon of “whispering chambers.”

  4. Math

    An ‘einstein’ shape eluded mathematicians for 50 years. Now they found one

    The shapes can form an infinite tiled pattern that never repeats. The first is a 13-sided shape nicknamed “the hat.”

  5. Math

    Scientists Say: Möbius strip

    Möbius strips may be easy to make, but they have some pretty mind-bending properties.

  6. Earth

    Scientists Say: Altitude

    Altitude is used to describe heights in geography, astronomy and math.

  7. Animals

    Random hops always bring jumping beans to shade — eventually

    It’s not fast, but jumping beans use randomness to maximize their chances of getting out of the sun’s heat.

  8. Math

    Scientists Say: Calculus

    Calculus is math that deals with curves, from their changing slopes to the areas they enclose.

  9. Math

    Meet the newest additions to the metric system

    The metric system just got its first update in 30 years. New prefixes will help scientists interpret the biggest — and smallest — numbers.

  10. Math

    Scientists Say: Mean, median and mode

    Mean, median and mode are all different ways to describe the middle value in a dataset.

  11. Math

    Let’s learn about dealing with math anxiety

    Writing about math anxiety and maintaining a “growth mindset” can help soothe stress about the subject.

  12. Math

    Scientists Say: Variable

    A variable is something that can be changed — such as a value in math, or a factor in an experiment.
