We are fond of saying things are symmetric, but what does that really mean? Intuitively we have a sense of symmetry as a kind of mirroring. Suppose we draw a vertical line through the middle of a ...

Unexpected atomic reversal: Researchers saw atoms in a crystal switch rotational direction during angular momentum transfer, a first in experimental physics. Terahertz laser control: Intense terahertz ...

For decades, temporal and inversion symmetry were taught as static geometric concepts, but 2026 has shattered that view with real-world demonstrations of symmetry in motion. From the first ...

Editor’s note: This story is part of Meet a UChicagoan, a regular series focusing on the people who make UChicago a distinct intellectual community. Carolyn Yackel, SB'92, flipped through photos of ...

A GCSE Maths video explaining rotational symmetry. This video looks at finding the order of rotational symmetry of different 2D shapes using worked examples. Find out more about GCSE Maths.

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

There's a part of the brain that enables us to perceive magnitude -- we can compare loudness when hearing different tones or compare the number of dots in a group at a glance. Neuroscientists have ...
