Deliberately breaking crystal symmetry widens topological bandgaps in 2D magnets made from light elements, predicting quantum ...

Even though the Eastern and Western halves of Earth are fairly different, they reflect the same amount of sunlight, a new ...

How Emmy Noether's theorem uses the Lagrangian to provide a formula for calculating the quantity of symmetries in a ...

In the very first microseconds of the Big Bang, something strange happened. Matter somehow outnumbered antimatter and kept the fledgling universe from annihilating itself. This break with conventional ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. Symmetry also has an aesthetic meaning, although this is ...

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 ...

Mirroring the mechanisms that make human faces and bodies—and those of many multicellular organisms—symmetrical, bee colonies build symmetrical nests when they are placed on either side of a ...
