Physics Nobel Laureate Kenneth Wilson Dies
Physics visionary Kenneth G. Wilson, winner of the 1982 Nobel Prize in
Physics, died at the age of 77 on June 15 in Maine of complications
following a lymphoma.
“Ken Wilson was one of a very small number of physicists who changed the
way we all think, not just about specific phenomena, but about a vast range
of different phenomena,” said Steven Weinberg, a fellow physics Nobel

Pretty sharp fellow; he thought up a lot of good things. But, occasionally

中国的号称是CERN的体积的两倍,能量也要高不少,
不可能便宜的。
欧洲这个玩意, 为了发现Higgs boson,花了132.5 亿美元,
每年的运行费就要额外的10亿美元以上。
中国的造假不可能便宜,看起来至少是500亿人民币以上的大工程。
后期也要花花的银子养着。
The total operating budget of the LHC runs to about $1 billion per year. The
Large Hadron Collider was first turned on in August of 2008, then stopped
for repairs in September until November 2009. Taking all of those costs into

高能物理的绝唱

作者是王孟源,哈佛高能物理博士


现代高能物理始於1940年代的量子场论(Quantum Field Theory),最初的应用是以
量子电动力学(Quantum Electro-Dynamics,QED)来解释电磁力。
在1950年代,加速器的技术突飞猛进,数以百计的高能粒子被发现;物理学家在整理
这些粒子的时候,注意到各种对称性(Symmetry),其中最深奥困难也最重要的是规范
对称性(Gauge Symmetry)。其实QED本身就是一个规范场论,但是它只是规范场论中
最简单的一种,叫可交换规范场论(Abelian Gauge Theory)。
1954年,杨振宁和他的学生Robert Mills解决了非交换规范场论(Non-Abelian
Gauge Theory)的难题,高能物理理论界随即注意到用非交换规范场论来解释弱作用力
和强作用力(宇宙中只有四种作用力:电磁力、弱作用力、强作用力和重力)的可能,
但是具体的细节还不清楚。

Data from a recent collision at the Large Hadron Collider (CERN) in
Switzerland has the scientific community as giddy as a 10 year old on
Christmas morning.
The data they are worked up about are a few spikes that may signify the
existence of the Higgs Boson particle, aka the "God Particle." The particle
is thought to be what all matter was formed out of and the cause of The Big
Bang. Though the data is still inconclusive until further review, it begs
the question...What if?

比如,我要Z'->jj的upper bound 研究,这个需要higher order下的你所谓的”计算机

你说的都是灌水指数。真正让人振奋人心的发现和科学创举,有几个是中国人做的?像
LIGO, 冥王星探测器,WMAP, Hadron collider 这样需要几十年长期不懈投入的划时
代的项目中国有人搞吗?

很对。
但造成这一切的元凶恰恰是中国和米帝学,一起向钱看。
最适合科研的就是社会主义大锅饭。可惜被邓矮给砸了。

Nothing is moving in the foundations of physics. One experiment after the
other is returning null results: No new particles, no new dimensions, no new
symmetries. Sure, there are some anomalies in the data here and there, and
maybe one of them will turn out to be real news. But experimentalists are
just poking in the dark. They have no clue where new physics may be to find.
And their colleagues in t... 阅读全帖

Plans to build a particle smasher in Japan to succeed the Large Hadron
Collider have suffered a significant setback. An influential report by
Japanese scientists concluded that they could not support plans to build the
International Linear Collider (ILC) in the country. The facility has been
decades in design and would study the Higgs boson, which was discovered in
2012 and is the last puzzle piece in particle physicists’ ‘standard model
’.

来自主题: Faculty版 - 我为尹希教授做的专访
Interview with Dr. Xi Yin

--- By Fiona Rawsontile, Sept 2015
This interview was inspired by an earlier interview of Dr. Yin I saw on the
Internet, which made me think that we can’t expect someone who normally
writes for entertainment to understand a physicist. To “provoke” a
scientist, we need another scientist. So I volunteered (to myself) and sent
an invitation to Dr. Yin, who was recently promoted to Professor in Physics
at Harvard Uni... 阅读全帖

The Nobel Prize in Physics 2013 was awarded jointly to François Englert
and Peter W. Higgs "for the theoretical discovery of a mechanism that
contributes to our understanding of the origin of mass of subatomic
particles, and which recently was confirmed through the discovery of the
predicted fundamental particle, by the ATLAS and CMS experiments at CERN's
Large Hadron Collider"

索性再给你比一比 Juniper 吹得最凶的scaling 吧, 这里Qfabric 和 VDX 也是半斤
八两, 谁好谁坏
还很难说。 这个题目技术性有点强, 通俗地说, Qfabric 没有遵照标准,自己也不
明说是什么技术
细节, 但是效果好。 Vdx 遵照IEEE标准, 性能也还可以,不像juniper 认为得那样
什么都做不了。
具体可以看下面的讨论, ADAM = Juniper, BROOK = brocade.

(CNN) -- Scientists say they have found hints of the existence of the Higgs
boson, a never-before-seen subatomic particle long thought to be a
fundamental building block of the universe.
In a highly anticipated press conference, researchers announced that two
independent experiments at the Large Hadron Collider in Geneva have turned
up signs of the so-called "God particle."
While the experiments haven't yet turned up enough data to confirm the Higgs
boson's existence, experts say finding the elu... 阅读全帖

(Reuters) - Scientists around the world said on Friday the discovery of sub-
atomic particles apparently traveling faster than light could force a major
rethink of theories on the makeup of the cosmos, but the findings would
first have to be independently confirmed.
"Extraordinary claims require extraordinary evidence, and this is an
extraordinary claim," eminent cosmologist and astrophysicist Martin Rees
told Reuters.
The CERN research institute near Geneva said measurements over three years

In an exclusive interview with the Guardian, the cosmologist shares his

A belief that heaven or an afterlife awaits us is a "fairy story" for people
afraid of death, Stephen Hawking has said.
