【科学趣史】推动科学的四个幻

itution of the kingdom of chemical 便是-element periodic law. At that time ,already discovered 63 kinds of elements, the scientists would have to think about whether there was a law of nature, so that the elements can be arranged, orderly, play their proper roles?

35岁的工程学博士早再行默默思索着这个问题，在疲倦中会进入了恶梦乡。

在恶梦里面他看到一张详见，原素们纷纷落在更好的格子里面。醒来时后他正要记下了这个详见的所设计理念：原素的政治性随原子序数的负数，呈现有有规律的变化。

早再行在他的详见里面为可能原素留下了都只，后来，很极快就有新原素来填满，各种政治性与他的应验前所未有地相吻合。

At the age of 35, the chemistry professor Mendeleev struggled with the question, in tired in sleep.In the dream he saw a form, the elements fell in the right box. When he awoke he immediately wrote down the table design concept: the properties of the elements with atomic numbers increased, presenting a regular change.Mendeleev left a vacancy in his vocabulary for the unknown elements , then, a new element appeared filling the variety , and consistent to his prophecies strikingly .

科学有史以来第三个都曾的恶梦

1921年复活节星期天之当年的黑夜，奥地利生物学家卡罗从恶梦中会醒来时，被绑过一张用纸迷迷糊糊地读到了些东西，围住活下去又睡着了。晚间6点钟，他突然间想起自己昨夜记下了一些极其重要的东西，却怎么也看不认清自己读到的是些什么鬼画符。幸运的是，第二天凌晨3点，逃脱的新思想又跑去了，它是一个鉴定的所设计作法，可以用来验证卡罗17年当年明确提出的某个假感叹是否正确。

The night before the 1921 Easter Sunday , Austria biologist Roy woke up from a dream, grabbed a piece of paper absently and wrote something,and then fall asleep again. At six o'clock in the morning, it suddenly occurred to him that he did write down some important things, but can not understand himself. Fortunately, the very next day at 3 am, the new thought came back again, it is an experimental design method.

卡罗赶紧整天，丢下研究团队，杀掉了两只青蛙，取出蛙心冻在生理玉井里面，其中会2号带着迷走大脑，5号不带。用电阻诱因2号胸腔的迷走大脑使胸腔晃动变慢，几分钟后把冻着它的玉井移置到5号胸腔所在的容器里面，结果5号胸腔的晃动也慢了。这个鉴定详见明，大脑并不必要功用于肌肉，而是通过特赦微生物来起功用，2号胸腔的迷走大脑不止时产生了某些生物体，它们溶解在玉井里面，对5号胸腔产生了功用。大脑冲动的工程学发送至就这样被挖掘出了，它掀开启了一个全新的研究领域，并使卡罗取得1936年诺贝尔生理学和医学奖。

Roy got up, went to the lab, killed two frogs, took the frog hearts soaked in saline, wherein one with the vagus nerve(NO.1), the other without(NO.2). Electrode stimulation vagus nerve of NO.1 that caused the heart to beat slow, a few minutes later, moved its saline to containers of NO.2, then the heart beat of NO.2 also slowed down. This experiment showed that, nerve does not directly act on the muscle, but through the release of chemical substances , cardiac vagal stimulation caused certain substances of NO.1, they dissolved in saline, did impact on NO.2 . Chemical transmission of nerve impulses were found, it opened up a whole new field of research, and made Roy won the Nobel Prize in physiology and medicine in 1936.

科学有史以来第四个都曾的恶梦

在工业化的服装生产显现出来之当年，人们内涵里面的鞋匠钩都是一样的：穿新线的新掀开在与钩尖相反的一后头，因此钩跨越皮带的时候，新线最后才跨越。对皮带鞋匠来感叹这没什么问题，但工业化的鞋匠机需要让新线再行跨越皮带。当时的发明家们采用了双后头钩或多钩的作法，但都效能不高。

In industrialized production before appearing, people in the concept of a sewing needle is the same: the threading open with tip instead of a head, so the needle through the cloth when, before finally passing through line. For sewing it no problem, but the industrial sewing machine needs to let the line through the cloth. The inventors have the double needle or needle method, but the efficiency is not high.

19世纪40年代，亚裔埃利亚斯．豪在不能解决这个问题的困恼中会做爱，恶梦见一帮凶残人要砍去他的后头或煎他来进食。关于这个细节有各有不同的感叹法，总之是无能为力大大的不妙，豪不顾一切地想爬出锅或躲避砍刀，但被生番们用斧头欺骗着，在这时他看到斧头的尖后头上掀开着穿孔。

Eighteen forties, Americans Elias Howe in cannot solve the problem of difficult to sleep, the dream of a barbarian would cut off his head or cook to eat them. About the details of a different account, anyhow is big bad situation, desperately want to climb out of the pot - or escaped machetes, but was looking with their spears to scare, when he saw the spear tip on a hole.

这个恶梦使他要求中会止皮带鞋匠的理论，所设计了钩穿孔掀开在钩后头两端的曲钩，适时使用飞梭来锁新线。1845年他的研制成功假设问世，每分钟能缝250钩，比好几个熟练工人还极快，无论如何实用的工业鞋匠理论再一显现出来了。

The dream made his decision to abandon manual sewing principle, design a pinhole opening in the needle end of the curved needle, used in conjunction with the shuttle for sewing. In 1845 his first model available, per minute to 250 stitches, than several skilled workers is also fast, truly practical industrial sewing principle finally showed up.
