trigger
一聲哨聲一個動作
這向來是班長操士兵們的基本中的最基本常識
如果一個哨聲的聲響長達30秒...那麼底下的士兵一定亂成一團
因為這30秒內你什麼時候做動作都可以
難怪 sequential circuit都是 edge-trigger

othogonal complement
y axis is not the orthogonal complement of x axis in R^3.
If something that is the orthogonal complement of x axis in R^3, it would be y-z plane.
And y axis is the orthogonal complement of x axis in x-y plane.
Q: Is y the o.c. of x in R^2?
