家园 呵呵,大学时候听过物理系一个家伙的报告

头一部分是经典力学---热力学---统计力学---量子力学/相对论之间的联系,第二部分就是物理学家的故事:说了牛顿不少问题,有和胡克的,更多的是和莱布尼兹的......

霍金那本"时间简史"的最后,好象也涉及到这些吧?也许那个演讲的就是抄霍金的.

看你们在科学版说"墒",想到马哲这一大块东西里面,恩格斯也评论过"热寂"说,据说他那本"自然辩证法"还是有宝(也是听老前辈说的).

家园 还真没看过《自然辩证法》

有空看看。劳动创造人类应该是他的原创吧,也是影响力最大的吧。

家园 【摘+链】希望有个好天气:一个关于集体意识的自然实验

ROGER D. NELSON "Wishing for Good Weather: A Natural Experiment in Group Consciousness," Journal of Scientific Exploration, Vol. 11, No. 1, pp. 47-58, 1997

---------- 摘要 ------------

Many human activities are affected by the weather, and there is a long history of rituals and ceremonial efforts aimed at controlling it. In modem societies, such efforts are largely vestigial and amount to informal hoping or wishing for good weather for special occasions. Reunion and commencement activities at Princeton University, involving thousands of alumni, graduates, family and others, are held outdoors, and it is often remarked that they are almost always blessed with good weather. A comparison of the recorded rainfall in Princeton vs. nearby communities shows that there is significantly less rain, less often, in Princeton on those days with major outdoor activities.

---------- 结语 ------------

Although many of us wish fervently for nice weather for special occasions,and some are even motivated to offer up a little prayer, it doesn't seem likely that many of us believe it will do any good. A modern education (such as Princeton delivers) tends to include a surfeit of implicit reasons and arguments against such an eventuality, and it certainly doesn't fit easily within our current scientific models of the world. Yet, we recognize that these models are incomplete,perhaps most glaringly because they have so little to say about human consciousness, including such hopes and wishes as might, possibly, affect the weather.

We have recently learned to view weather patterns in terms of chaos theory,where infinitesimally small effects can expand into great changes; the beat of a Brazilian butterfly wing may propagate through complex weather systems to cause a downpour in a small New Jersey town. Could the effects of communal interest from a great concentration of Princetonians compete with that butterfly wing?

A look at actual weather data seems to suggest that precipitation tends to stay away from Princeton for the P-Rade, and Class Day, and Commencement,to a somewhat unlikely degree. These intriguing results certainly aren't strong enough to compel belief, but the case presents a very challenging possibility,because if the analysis is correct, the only good candidate to explain the apparent differences, other than chance, would seem to be an influence from an informal but powerful communal wish for dry weather. In any case, it surely is premature to conclude, as the graffito has it, that God went to Princeton, but we may need to reconsider the old saw, "Everyone talks about the weather, but nobody does anything about it."

家园 嗯,再往下说就有争议了

个人感觉,恩格斯的说法,"劳动创造人类"也好,"自然辩证法"里面的某些提法也好,都是建立在19世纪人类对自然界的观察基础上的(当然马克思的政治经济学也是).现在过去100多年了,新发现和新情况很多,人类起源,古代社会的研究都有巨大的突破和进展,有些是必然会被"修正"的.

家园 其实这是显然的,本不该有争议.只有宗教教义才忌讳"修正"
家园 算了吧!

眼光和魄力尽有别的方式可以表现;在现实条件下这样表现眼光和魄力不过是阻碍发展的代名词。

当然,个人不认为如此;只认为其眼光这一次是大大的有问题;再有就是人年纪大了,有走捷径的念头是可以理解的--兄台也要走这个‘捷径’吗?

我们说的是所谓‘人体科学’。

家园 鹰翔九天, 其境界岂是燕雀之所能知?
家园 《人民日报》和《新闻联播》尽是类似的废话……
家园 我硕士课程中的《自然辩证法》得了A

是我为数不多的几个A之一。另外,“自然辩证法”现在叫做“科学哲学”。

家园 哈哈哈哈,这个是最好玩的;心比天高的‘鹰’和不知‘之’所云

贵‘鹰’心比天高,觉得自己连空气都不需要了。

我们还是做自己造火箭的‘燕雀’吧。

学问从来是不认你是张三还是李四的;您就慢慢排您的座次吧

兄台热衷说佛,原来说出的是这个结果;抱歉摇头了。

另:好玩的还有这个‘燕雀之所能知’。不知‘之’所云

家园 没说不让指责啊,只是以马哲来说人家方法不对,不敢苟同
家园 我觉得马哲对钱的影响应该没那么大,后面的应该是应景之谈而已。

很简单,在美国的时候,他的大部分学术研究应该已经定型了。如果有人告诉我那时候他老人家已经是地下党员了,我没话说。

位于不同的位置,身怀不同的能力,就应该负不同的责任,所以,毛无法为大跃进、3年灾害、文革推脱,但是对于钱钟书、钱学森这样的知识分子,在非常时期的作为,还是不要求全责备的好。

我宁愿把钱学森的那篇文章,看做应景之做,那个时代,科学家,数学家做这种违心的事情,多了去了,连华罗庚都不得不做过。后人把这篇文章拿出来做理论上的攻击,有些无聊,我想钱本人也羞于提起它。

每个人在自己的学习过程中,都会找到自己的一套哲学方法,教条化的马哲,对中国的科学界是个僵化的外壳,束缚了人民的思维。就如同儒家文化也非常的灿烂,但是这个文化自然的排斥自然科学,中国的数学,物理学等接触西方之前很少有进步。

家园 啊?这名字改的有点晕

"科学哲学"好象是特指波普尔,拉卡托斯,库恩他们的,其中大部分不太赞成马克思主义.

家园 这种题目......

不就是一个问题上犯了错误,也许很粗浅,就牵扯到物理好不好。欧拉算1+1/4+1/9+1/16+......的方法也是错的(虽然当时还没人能按照正确的方法算出来,他的错误并不复杂),可谁敢去评论他的数学好不好。

家园 可能老钱也后悔得要死,写了这么一篇东西。
