To cook a perfect steak, use math
As a steak cooks in an oven, movement of liquid within the meat causes it to become extra juicy in the center in a way that can be predicted by mathematics.

The U.S. has resisted the metric system for more than 50 years
Australia adopted the metric system 50 years ago. The United States tried by passing legislation for a voluntary conversion that was largely ignored.

How large a gathering is too large during the coronavirus pandemic?
Mathematical models explain why large gatherings are especially dangerous in an epidemic, and identify how large is too large.
- Space
NASA icon Katherine Johnson has died at the age of 101
The “Hidden Figure” captured the public’s admiration after the story of her career was publicized in a 2016 book and film.

How a quantum technique highlights math’s mysterious link to physics
Verifying proofs to very hard math problems is possible with infinite quantum entanglement.
- Physics
A quantum strategy could verify the solutions to unsolvable problems — in theory
A quantum technique for verifying solutions to difficult problems could apply to an “unbelievably huge” class of puzzles.
- Math
Color-changing fibers help reveal mysteries of how knots work
Experiments with colorful fibers helped scientists discover a few simple rules behind knots’ varying strengths.

Why Rembrandt and da Vinci may have painted themselves with skewed eyes
A strongly dominant eye, not an eye disorder, may explain why some great artists painted themselves with one eye turned outward.
- Math
How Julia Robinson helped define the limits of mathematical knowledge
Born 100 years ago, Julia Robinson played a key role in solving Hilbert’s 10th problem.
- Math
A new book shows how not to fall for dubious statistics
Skipped statistics in school and wonder what you missed? David Spiegelhalter’s ‘The Art of Statistics’ has got you covered.
- Math
Mathematicians report possible progress on proving the Riemann hypothesis
A new study advances one strategy in the quest to solve the notoriously difficult problem, which is still stumping researchers after 160 years.
- Physics
The kilogram just got a revamp. A unit of time might be next
After years of preparation, new definitions for the basic units of mass, temperature and more have now gone into effect.
