If its invisible how can we know it's there?

如果它看不见我们怎么知道有它存在
There are various-- there are

有许多出色的《纽约客》漫画
several good New Yorker cartoons about that problem.

都是以此为话题作画
One shows a group of well-dressed people

有一幅画了一群衣着考究的人
gathered in a farm field Darien Connecticut

聚集在康涅狄格州达伦镇的农场
looking out with binoculars to find the invisible hand,

举着双筒望远镜寻找那看不见的手
which has been reported to have appeared there.

因为据报告那手曾在此出现
Another is a store with a sign across the front,

另一幅画了一家小店门口有个标牌
"Store closing,"

上面写着"结束营业"
And then a caption under the "Store closing" Sign:

在"结束营业"标牌底下有一个说明
"Bitch-slapped by the invisible hand."

"被看不见的手狠狠地煽了一巴掌"
The condition under which the invisible hand works is actually--

其实必须要满足几项条件
