对称性破缺（symmetry breaking)
对称这个东西很pp,试想那个mm长的左右脸不一样，那肯定就不是ppmm了
呵呵
对称所对应的守恒也给大家很多方便，好处多多
另外还和线性系统有关，这个更没有什么混沌之类麻烦
问题是如果什么都是对称的
那就没有偶们了
想想那些化学反应啊，是热运动，那里就有对称性破缺的
就是熵啊，这个东西不守恒
守恒是对称的，不守恒就是对应对称性破缺了
没有了化学反应，那偶们的生命从何而来啊
其实还有更深层的对称性破缺（比这个还不明显）
有一种对称性，叫规范对称性（gauge symmetry)
就是你如果学电磁学里面提到的那个关于矢势的规范
偶上次提过，我们可以把相互作用归归类
分到各种规范群下面去
电磁作用是U(1) (就是一为的幺正转动，其实这个群和二维的实转动是一样的）
问题是你如果写入了光子-光子耦合
这个对称性就被破坏了
而光子-光子耦合其实就是光子的静止质量项
上次TELL问过的，所以偶上次说
光子有静止质量，直接的物理结果就是
光子和光子的作用在TREE LEVEL就有了
那样光和光交到一起就有互相影响了

Direct and indirect CP violation are two mechanisms that break the symmetry

discovered indirect CP violation for B and anti-B (or B-bar) mesons in 2001.
BaBar’s new result is the first observation of direct CP violation for B/
anti-B mesons.

My point is general relativity does not need gauge symmetry as a guiding principle.
you can call it conformal gauge, I can call it conformal frame.
gauge symmetry is a very strong principle that guide us through the building
of standard model (and some extensions) of particle physics. But it seems not
powerful enough to give us a qunatum gravity. and whatever it can say about
the classical gravity, we don't necessarily need it to reach the same
conclusion.

的懂的朋友
The Higgs field is mutilple scalar fields with some symmetry.
According to the Standard model of particle physics, this symmetry
is spontaniously broken, and gauge bosons and fermions could derive
mass from the Higgs field.
What does this mean? Originally, there is no fundamental difference
between the n scalar fields, and they could indeed be linked by
a gauge transformation. However, the minimal of their potential energy
(called vacuum) is located at points where the field is non-zero. |

发帖数: 50 | 25 Let's construct a function on the square.
Since the symmetric group of a square is D4,we need only to construct
the function on 1/8 of the square which is a triangle.
The other values can be obtained by symmetry.
A simple example is a bump in the triangle which is 0 on the
boundary and is smooth.Then the maximal value or minimal value
of the function may not be on the symmetry axis.
One can construct more complicated function similarly.
Hope this enlights. |

纯属个人猜想，cutter 可能会尽量往大的里面cut, 但是不至于牺牲很大啊。因为我
们买钻都是看亮度看眼缘什么的吧；如果牺牲了漂亮的程度，对卖钻一样的不利；如果
没有牺牲肉眼可区别的亮度，那就无所谓。倒是有点可能cut 成重量其实为0.89X 的钻
被说标识成0.90，因为这一点肉眼根本看不出来，大家只能看vendor 的说法。所以我
会觉得这个0.9 可能不一定完全到0.9， 但是不会觉得它的symmetry 什么的很可能有
问题。
我倒觉得1不错，就贵了600，颜色和clarity 都好，应该看起来也不会比0.92的小。

U.N. Official Cites ‘Strong Possibility’ of War Crimes in Gaza Conflict
GENEVA — The United Nations’ top human rights official, Navi Pillay, said
Wednesday that there was a “strong possibility” that Israel and Hamas have
committed war crimes with indiscriminate attacks on civilians during more
than two weeks of fighting with militants in Gaza.
Opening a special session of the United Nations Human Rights Council in
Geneva, Ms. Pillay... 阅读全帖 |

层子模型前后－关于声称以马 克 思主义哲学指导物理学研究的案例分析
关 洪
（中山大学物理系，广州 510275）
摘要：本文回顾了从20世纪50年代初期开始，在我国对“物理学中的唯心主义”进
行的多次批判运动。特别是依据“百花齐放”的方针，对层子模型前后声称以马克思主
义指导基本粒子理论研究，并指责同行物理学家为“唯心主义”的一些正式发表的言论
进行了案例分析。

一 我国对“物理学中的唯心主义”批判的启动和推进
中国科学院主办的刊物《科学通报》继在1951年6月号登载了从苏联《哲学问题》

物理的数学基础什么时候跟经济接近了？
你去看看物理里面的SYZ conjecture, mirror symmetry....
那都是当代代数几何的最前沿领域，都得过田野奖的，
经济的就搞了个随机过程的应用而已，差了整整三万光年 |

你大一学了mirror symmetry,那你肯定是高中学完string theory，初中学完
quantum field, 小学学完四大力学的了 |

发帖数: 994 | 48 这个牛皮恐怕你又吹过头了。说说看，大一学的“mirror symmetry"就算和弦论无关，
至少和 calabi-yao manifolds 有关吧？大一你就搞懂了这些？ |

发帖数: 994 | 49 好吧，俺不敢跟天才比。
那天才自己跟自己比吧，您说的“我在大一就学习了邱的镜面对称（当时是作为高代的
辅助内容自学的）”，您知道邱的“mirror symmetry"和高代之间深浅的差别吗？
您那个牛皮翻译下相当于：我在学习字母时就学习了原版莎士比亚全集（作为学习26个
字母的辅助内容自学的）。 |

你大一学的“mirror symmetry"到底是“皮毛”还是“精髓”？ |
