例如卡文迪许扭秤实验测万有引力常数,八棱镜测光速等,这些实验设计巧妙又不贵,通过一些装置一个方法就能把原先很难测的东西测出来,仪器还很简单,感觉棒棒的,科学史上还有类似巧妙的实验吗?01缸中的大脑(Brain in a Vat)没有比所谓的“缸中的大脑”假说更有影响力的思想实验了。这个思想实验涵盖了从认知学到哲学到流行文化等各个领域。实验的内容是:想象有一个疯狂科学家把你的大脑从你的体内取出,放在某种生命维持液体中。大脑上插着电极,电极连到一台能产生图像和感官信号的电脑上。因为你获取的所有关于这个世界的信息都是通过你的大脑来处理的,这台电脑
Such as Calvin Di Xu torsion scale experimental universal gravitation constant, octagonal prism metering speed, these experimental design ingenious and not expensive, by some means a device can measure the original hard to measure, the instrument is still very simple, feel great There is no such thing as a clever experiment in the history of science? Brain in a Vat There is no more powerful thought experiment than the so-called “brain in a cylinder” hypothesis. This ideological experiment covers everything from cognitive science to philosophy to popular culture. The content of the experiment is: Imagine a crazy scientist taking your brain out of your body and putting it in some fluid for life support. Electrodes are attached to the brain, which are connected to a computer that generates images and sensory signals. Because all the information you get about the world is handled through your brain,
