霍金的名言 要英语的

理论什么的就不说了不算什言,本来霍有名的黑洞假说也另一名科学证明有错误,所以就不说理论方面的了1.当你面临着夭折的可能性,你就会意识到,生命是宝贵的,你有大量的事情要做。

2.关于时空物理的问题争议,我不敢和我的同事们打赌,因为我怕他们是通过虫洞跑来的未来人,他们很清楚地知道标准答案。

3.妓女和科学家是最好的两个职业。

4.一本书中多一个数学公式就会减少一半读者。

5.上帝既造就天才,也造就傻瓜,这不取决于天赋,完全是个人努力程度不同的结果。

Was there a beginning of time? Could time run backwards? Is the universe infinite or does it have boundaries? A Brief History of Time will tell you the truth. A Brief History of Time is a great book by Professor Stephen Hawking, the world's most famous physicist, black hole theory and the Big Bang theory’s creator. It is a good book of modern theoretical physics. You can get an outline of our knowledge currently about gravitation, time, big bang and so on. I still cannot believe this is written by the most gifted scientist for general public. Using simple language, Stephen illustrated a full picture of what the universe is and what time is, within the bundary of human beings current understanding. Never imagine pure theratic physics could be so interesting and easy to understand, although I have to admit that I only understand 40% of what he is saying. After reading the book, I felt strongly pessimistic with the further advancement of theoretical physics. It is, in my opinion, quite a dead-end job. Any newly proposed physical theory 暑期读书笔记&影视剧点评精选 读书笔记影视剧点评书评舞台艺术点评读后感 need to be in good accordance with experimental observation to be proved and publicly accepted. Theoretical physics focuses on the extremes -- the lightest particle, the earliest stage of the universe, etc. According to Hawking, we human being were not able to produce the required extreme conditions to test the new theories. Therefore we were not able to prove the authenticity of them, thus not able to advance. Prof. Hawking wrote the book in 1988. Twenty-two years later, we regrettably find that the improvement in experimental methods and equipments in the area of particle and cosmo- physics is trivial compared to what is really needed. But you should not go for understanding everything inside the book because the physics require proper math formulae for complete understanding. I can't understand uncertainty principle. I think particles' position and velocity are fixed in a way that we are not recognized now. However, I agree with following opinion: 1, There is no single formulation of the fundamental theory. 2, The whole collection of different formulations could be regarded as a complete unified theory. As an unfortunately result of the theories not being able to be proved, or falsified, a whole lot of different theories, all interwoven with indecipherable mathematics burgeon. To catch up with the state-of-the-art, a new theoretical physicist has to study the majority of these theories, and the very bespoke mathematics attached to each of them. In my opinion, the process would be very exhausting, and unworthy, since most of the theories will be proven completely nonsense. I believe the difficulty and boringness will not stop a small group of very ambitious people from pursuing, in the hope their home-made theory would someday equate the status of that of Newton's and Einstein's today. I personally would not be willing to see my child become one of them.

霍金的英语介绍 100字左右,带中文

黑洞无毛定 对于物理学家来一个黑洞或一块都是极为复杂的物体,因为对的完整描述,即包括它们的原子和原子核结构在内的描述,需要有亿万个参量。

与此相比,一个研究黑洞外部的物理学家就没有这样的问题。

黑洞是一种极其简单的物体,如果知道了它的质量、角动量和电荷,也就知道了有关它的一切。

黑洞几乎不保持形成它的物质所具有的任何复杂性质。

它对前身物质的形状或成分都没有记忆,它保持的只是质量、角动量、电荷。

消繁归简或许是黑洞最基本的特征。

有关黑洞的大多数术语的发明家约克·惠勒,在60年前把这种特征称为“黑洞无毛”。

一开始,这只是一种猜测,20世纪70年代得到了严格的数学证明。

这是包括默东天文台的布兰登·卡特和澳大利亚的加里·班亭在内的理论物理学家l5年努力的结果。

他们证明,描述一个平衡态黑洞周围的时空几何只需要3个参量,从而证实了惠勒的表述。

黑洞的参量是可以精确测量出来的,尽管是借助于理想实验。

可以把一颗卫星放在围绕黑洞的轨道上,并测量卫星的轨道周期,从而得到黑洞的质量。

黑洞的角动量可以通过比较朝向视界的不同部分的光线的偏转来测量。

对于上文提到的有一定质量的克尔-纽曼黑洞,电荷和角动量都有上限,也就是都受到保证视界这一条件的限制。

如果在某个大质量恒星的引力坍缩过程中,这个限制被违反,黑洞就成了裸奇点,并能影响到宇宙中的远距离处。

然而,物理学家有充足的理由相信,这种情况被自然规律所禁止,因而不会发生。

既然只由3个参量支配,一个黑洞就像一个基本粒子一样简单。

尽管基本粒子也是把质量、角动量、电荷集中在一个很小的体积内。

但是,只要考虑一下视界存在的条件,就知道没有什么比基本粒子与黑洞的差别更大。

以电子为例,实验已经确定它的3个参量,就相同质量来说,电子的电荷和角动量·超过黑洞上限的1088。

这个令人惊谔的数字甚至超过了可观测的宇宙基本粒子总数,而这正是一个电子和一个克尔-纽曼黑洞之间差异的量度。
