Einstein, one of the greatest scientists in human history, has a famous saying “God never play dice." which indicate that given enough information, everything in our world can be predicted. According to Newton's law, for example, if we know the current speed, acceleration and quality of an object, we can foresee its speed and position in the next interval precisely. Ironically, this certain world under the frame of classic physics is totally crushed by the quantum theory which describes a micro world full of chaos and uncertainty. Scientists can never predict the movement of a quantum accurately, but just describe them with a series of vague possibility. In a scientific sense, truly the past is no predictor of the future.
However, I have to ask why people need to know their future? And to what extend can we claim that we predict the future? As to me, the answer for the first question is we scan the future for a change of it according to our willing or at least prepare for it. For that purpose, contrary to the claim of this issue, the development of our science and technology argues that actually the future is predictable. Because of our study of the astronomy, we can predict the existence of a new planet; agriculture, we can cultivate our crops properly to rise the production; history, it is possible for us to avoid some disasters of humanity and better organize our society. And furthermore the seed of the future is often buried in the past. If we want to have a better understanding of the un-known, we must have understand (understood) the known. It is for his comprehensive study of human history that Max can unveil the inherent principles of the development of our world in his great work “Capital” which, to some extend, predict the occurrence of the recent economic crises in the developed countries. For most of our current knowledge is a summary or derivation from our former experience, if we accept the claim “the past is no predictor of the future”, we have to admit our knowledge is useless ironically. Yet any people with reason will not agree.
读到这有点混乱了~~开头上来说在经典力学的框架下,过去可以预知未来,在量子力学中不可能,而这段又说资本论中语言了经济危机~~观点不太明确呀
The answer for the second question is also obvious. If we study the past for a better future, in many case, it is unnecessary for us to make a precise foresight. A vague one is enough. A weather forecast just need to tell common people whether tomorrow will be sunny, snowy or rainy so that they can decide whether it is necessary to take an umbrella before going to work. As for when the rain will begin and what the precise precipitation is, they are just meaningful for meteorologists. In the same way, we don't need to know the weather in a month or even a year, a general forecast of a week is adequate to guide our travel plan. Although the future is changeable and influenced by numerous factors, in a limited time interval, the future is predictable indeed in a rough, yet useful accuracy.
As no one can deny the exploits of our modern technology, we cannot ignore the significance of our past. It is based on the experience and lessons we learn from the past we achieve our current modern society. The past, if well studied, will be a precious fortune for human. Without the past as a load on our shoulder, we won't move on so well and so quickly in our way to the future.
主要问题:
1.前面提到了,观点有点反复,而且有些矛盾,不知道是不是我理解的不太对,我觉得整篇看下来你的观点是过去是可以预测未来的,但量子力学那块觉得有些多余了~虽然跟经典力学构成了个对比,但我觉得对于阐述你的观点没有啥好处
2.对于第二个问题预测的程度,说不出的感觉,有点怪怪的,你的例子我理解,但是我觉得不应该很直接给出it is unnecessary for us to make a precise foresight.,这句话是有问题的
3.打个分:3.5分 |
