# 眾害取其輕 3

The least of all evils 3

（安：其實可以把”眾害取其輕”這個概念表達成”成本最低”。）

”evil”卻表示你一定要忍受一些很難忍受的事情。

（安：把”least cost”譯成”成本最低”不太準確。可能將它譯做”代價最低”會好一點。）

”眾害取其輕”(the least of all evils)這個表達式

# Yang–Mills theory

I should explain that “Yang-Mills” theories are nonlinear generalizations of electrodynamics which can describe forces such as the weak and strong interactions.

— How Far Are We from the Quantum Theory of Gravity?, R. P. Woodard

Yang–Mills theory is a gauge theory based on the SU(N) group. It was formulated by Yang and Mills in 1954 in an effort to extend the original concept of gauge theory for an Abelian group, as was quantum electrodynamics, to the case of a nonabelian group with the intention to get an explanation for strong interactions.
