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.

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.
- Math
Scientists Say: Equation
An equation states that two groups of numbers or variables are equal to each other.

Let’s learn about pi
It’s not just an excuse to eat pastries. This number helps describe everything from the smallest particles to planets orbiting other stars.

Why some icicles become scallops not spikes
The newfound — and at times quirky — shapes reflect the density of water surrounding submerged ice.
- Math
Scientists Say: Geometry
Geometry is math that allows people to measure, analyze and compare figures in space.
- Life
From icebergs to smoke, forecasting where dangers will drift
Smoke drifts. Fish eggs float downstream. Where such drifting things end up may seem a mystery. But research can predict where they’ll end up.
- Animals
Endangered or just rare? Statistics give meaning to the head counts
Whether studying tiny birds or massive whales, researchers collect a lot of data. The field of statistics helps them make sense of those data.
- Math
Scientists Say: Pi
Pi is the ratio of a circle’s circumference to its diameter. But some mathematicians say life would be easier if we used a different ratio instead.

Explainer: What is statistics?
Scientists use statistics to design studies, analyze data and evaluate uncertainty. You’ll find it in biology, climate change, medicine and more.
