Grids based on an even number of grid columns can suffer from too much symmetry if text and graphics are confined to individual or double grid columns throughout.

基于偶数的栅格可能会遭遇过于对称的困扰，假如文本和图形总是占据1 - 2个单元格的话。

In a bid to restore yet more symmetry to the universe, a number of particle physicists are developing a theory called supersymmetry.

ECONOMIST: Particle physics makes sense, but it assumes too much

This is the order of symmetry of the crystal (in other words, the number of ways it can be rotated to produce a pattern identical to the original).
