div curl F = 0
this is a good question.think about that
divergence of something is positive,means this thing is a source.
divergence of something is negative,means this thing is a sink.
还是用中文吧,
你这么想象现在有一潭水,
如果某一点的div 是正的,它就是一个源泉,里面有水源源不断得冒出来.
如果某一点的div 是负的,它就是一个下水道,水被吸进去了.
curl是什么呢,是一个旋转,你就当它是一个漩涡,漩涡的旋转使得吸进来的水等于排出去的水,所以它的div就是0.
