The principle of mirror symmetry, which states that nuclear structure remains the same when protons are swapped for neutrons and vice versa, has been found to be broken in the lowest-energy forms ...

In general usage, symmetry most often refers to mirror or reflective symmetry; that is, a line (in 2-D) or plane (in 3-D) can be drawn through an object such that the two halves are mirror images ...

"It is kind of natural that GW200129 breaks mirror symmetry, as this system is known to have a precessing [wobbling] orbital plane," Koustav Chandra, team member and a scientist at Penn State ...

In frontal symmetry, the left side of a building’s facade mirrors the right (the entrance usually being in the middle); in axial-plan symmetry, the rooms on one side of the axis are a mirror ...

"Mirror symmetry already exists in vector optical ... fields and spin angular momentum and energy flow in the focal plane. We first propose the kaleidoscope-structured vector optical fields ...
