德国科学家黑姆霍兹说:“1891年我解决了几个数学和物理学上的问题,其中几个是欧拉以来所有大数学家都为之绞尽脑汁的.……但是,我知道,所有这些难题的解决,几乎都是无数谬误以后,由于一系列侥幸的猜测,才作为顺利的例子中的逐步概括而被我发现”。可见,在解决问题的过程中,猜想在不断地起作用,乃至指导着你的整个思维活动。 German scientist Heimholtz said: “In 1891 I solved several mathematical and physics problems. Several of them have been brainstormed by all the big mathematicians since Euler.... But I know, The solution to all these problems was almost always after countless delays, and I was discovered as a step-by-step summary of a smooth example due to a series of flirtatious speculations.” It can be seen that in the process of solving the problem, conjecture works continuously and even guides your entire thinking activity.
