This suggested that the so-called "isospin symmetry" between up and down quarks might be broken by more than expected due to the differences in their electric charges and masses—a discrepancy ...

Over the past decades, researchers have been trying to develop increasingly advanced and powerful quantum computers, which ...

This kind of symmetry is called rotational symmetry. Rotational symmetry is where a shape or pattern can be rotated or turned around a point and it looks the same. Have a go at this crafty ...

The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational ...
