Sometimes we get letters here at Moment of Science asking whether psychics are for real.
我们的科学一刻栏目有时会收到观众来信询问那些精神能量是否真的存在。
Well,despite the TV. shows,there isn't any scientific evidence that psychic powers,such as mind-reading,actually exist.
好吧,尽管电视节目有过播放，但没有任何科学证据表明诸如读心术等的精神力量实际上存在。
That doesn't prove they don't exist-just that,so far,there's no reason to think they do.
也不能证明它们不存在,到目前为止,没有理由认为这种精神能量的确存在。
Still,the famous scientist and popular writer Isaac Asimov made an interesting observation about mind-reading once.
不过,著名科学家及流行作家艾萨克?阿西莫夫对于读心术做过一个有趣的观察。
Many people across the centuries have claimed they could read other people's minds.
在过去的几个世纪里,许多人声称他们可以读懂别人的内心。
If this is true,Asimov points out,then mind-reading would be a fact of nature.
如果的确属实,阿西莫夫指出,那读心术将成为一种与生俱来的能力。
It would be one of things that the human brain can do,just like dreaming or maintaining your body temperature.
这将是一个人类大脑可以做的事情,就像做梦或维持你的体温一样。
That would mean that mind-reading would have to be the result of evolution.
这意味着读心术是进化的结果。
