Miasma theory was one of those things you sometimes hear about in history and they sound so screwy you almost can't believe people actually thought it was real.
Fred had even mentioned his military service in previous interviews with police, referenced killing people in Vietnam as a reason why his polygraph was screwy.
So, the area of this parallelogram is sort of a screwy roundabout way to describe the vector's y-coordinate; it's a wacky way to talk about coordinates, but run with me.
因此,个平行四边形的面积是一种描述向量 y 坐标的扭曲的迂回方式;是一种奇的谈论坐标的方式, 但跟我一起跑吧。
