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.

Math
Scientists Say: Parabola
A parabola is a Ushaped curve, where every point along that curve is the same distance from another point and a line.

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

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 13sided shape nicknamed “the hat.”

Math
Scientists Say: Möbius strip
Möbius strips may be easy to make, but they have some pretty mindbending properties.

Earth
Scientists Say: Altitude
Altitude is used to describe heights in geography, astronomy and math.

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.

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

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.

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

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.

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