A landmark proof in computer science has also solved an important problem called the Connes embedding conjecture. Mathematicians are working to understand it.

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.

Mathematicians have figured out how to expand the reach of a mysterious bridge connecting two distant continents in the mathematical world.

Sometimes a mirror that reflects 99.9999% of light isn’t good enough.

This April, find the fatal flaws in two paradoxical claims — one about a perpetual source of energy and the other about whether you will ever see the solution to these puzzles.

When 50 mathematicians spend a week in the woods, there’s no telling what will happen. And that’s the point.

Three progressively heavier copies of each type of matter particle exist, and no one knows why. A new paper by Steven Weinberg takes a stab at explaining the pattern.

While the age-old chicken-and-egg paradox is easily answered, the question of infinite regress in physics is far from resolved.

A recently unearthed fossil and new genomic discoveries are filling important gaps in scientists’ understanding of how primitive green algae eventually evolved into land vegetation.
