回顾医学史,科学研究真是吃足固定思路的苦头。W.Harvey在十七世纪,费了多大的劲说服人们:心脏收缩是血液流动的动力,而不是“血液加压于心脏使心脏膨胀起来”。“物必自腐而生虫” 的概念一直流行到巴士德。现在谁都知道微生物是腐败的原因。可见如果没有一个强大的冲击,人们——包括科学家在内是不会轻易放弃脑袋里大量的“已有的”概念的。
Recalling the history of medicine, scientific research really suffers from fixed thoughts. In the seventeenth century, W.Harvey spent a lot of effort to convince people that heart contraction is the driving force of blood flow, not “blood pressure pressurizes the heart and expands the heart.” The concept of “the object must be rot and worms” has been popular with the Bache. Everyone now knows that microbes are the cause of corruption. It can be seen that without a strong impact, people, including scientists, will not easily give up the large number of existing concepts in their heads.
