物理学家谈吃 (Physicists talking about food)

中国人以食为天, 见面就谈吃。连中国物理学家也不例外。(以下从微薄对话整理. Google translation below.)

兔斯基: 二傻师傅说过:【宇宙本来就是一锅粥】! 怎么,你要把这锅粥变成一锅面条?


有啊: 粥里的波满足欧拉方程。面条汤里的波满足麦克斯维方程。
我们真空里的波(光波)满足麦克斯维方程。所以宇宙是一锅面条,不是一锅粥。

【这里 一锅粥 = superfliud (particle condense)
       一锅面条 = string-net liquid (string-net condense)

  见 http://dao.mit.edu/~wen/talks/LightStory.htm


兔斯基: 到底是粥是面条还是面条汤嘛?!


有啊: 不好意思。应是“面条”,不是“汤”。是“面条里的波满足麦克斯维方程”。注意:是干面,不是汤面。


兔斯基: 记得《物理》上用的是“汤面”。


有啊: 真仔细。 说“汤面”时,很多人注意“汤”不注意“面”。 “干面”更准确。


绿豆蛙: 赤果果的热干面 论如何通过热干面认识宇宙。


兔斯基: 那brane world就应是一锅凉皮?!


有啊: 我还真考虑过“凉皮+面条”,希望同时得到满足Maxwell方程的光波与满足Einstein方程的引力波。没成功。看来宇宙不是凉皮面条。但宇宙里一定有面条。


绿豆蛙: 这面条,凉皮,怎么看怎么像民科。


有啊: 面条凉皮不是民科,是量子系统。 面条凉皮的希尔博特空间和哈密顿量都已给出。用哈密顿量,我们可以计算面条凉皮里的波。我们发现面条里的波满足麦克斯维方程,而凉皮里的波不满足爱因斯坦方程。


兔斯基: 2013年,高能物理实验发现了Higgs boson, 证实了我们生活在BEC中, 大锅里有粥是肯定了。 至于锅里是否有面条凉皮, 要设计判定性实验并说服实验家。


有啊: 同样的逻辑,我们老祖先,在25万年前的生活中,发现了光,证实了我们生活在面条中, 大锅里有面是肯定了。 还有,1897年,约瑟夫·汤姆逊 发现电子,也就是面条的端点。进一步证实了我们生活在面条中, 大锅里有面是非常肯定了。另外,Higgs boson有质量,而BEC里的波无质量。发现Higgs boson, 不能证实我们生活在BEC中。大锅里有粥没粥还说不定。


baby猫: 我们南方人认为,宇宙原本是一锅大米粥。不知道什么缘故,里面的颗粒连成了长长的线状,就变成过桥米线了。


有啊:  很有意思的想法。 可以通过宇宙观测,检验此想法的正确性。我得算算大米粥变成过桥米线的量子相变,及其可观测的预言。

Chinese people to kind of god , met to talk about eating . Even Chinese physicists are no exception. ( Hereinafter finishing from the meager dialogue )

Rabbit Chomsky : two silly chef said: "universe  originally gruel !" How you want it to become a pot of porridge pot noodles ?

There Ah : porridge wave satisfy the Euler equation. Noodle soup wave satisfy Maxwell equations . We vacuum wave ( light ) to meet Maxwell equations . So the universe is a pot of pasta , not gruel .

[ Here gruel = superfliud (particle condense)
       
Pot noodles = string-net liquid (string-net condense)
 
See http://dao.mit.edu/ ~ wen / talks / LightStory.htm ]

Rabbit Chomsky : in the end is a porridge or noodles soup noodles Well ? !

There Ah :I'm sorry . Should be " noodles ", not " soup ." A " wave noodles satisfy Maxwell equations ."
Note : It is a dry surface , not noodles .

Rabbit Chomsky : I remember using the "physical" is " noodles ."

There Ah : really carefully. Said, " noodles " , many people pay attention to " soup" pay attention "face ."
"Dry side " is more accurate.

Frog : dry noodles on the red fruit is dry noodles understand how the universe .

Rabbit Chomsky : That brane world should be a pot of Cold ? !

There Ah : I really thought about " Cold + noodles " and hope to be met while Maxwell equations satisfy
Einstein gravitational waves and light waves equation . Did not succeed. Kanlai universe is not Cold noodles. But the universe must have noodles.

Frog : This pasta , Cold , how to see how people like Branch .

There Ah : Cold noodles instead of China branch , is a quantum system . Cold noodles Hilbert space and
Hamiltonian are given . With the Hamiltonian, we can calculate the Cold noodles in the waves. We found the noodles in the waves meet the Maxwell equations , and Cold wave does not satisfy Einstein equations inside .

Rabbit Chomsky : 2013 , high-energy physics experiments found the Higgs boson, confirms that we live in a BEC in a large pot of porridge is yes . As to whether the pot noodles Cold , to design experiments and to determine convince experimentalists .

There Ah : the same logic, we ancestors , the living 250 thousands years ago , we found a light , confirming that
we live in the noodles in a large pot with masking is affirmed . Also, in 1897 , Joseph Thomson discovered electron , which is noodles endpoint. Further confirms our lives in noodles , there is a large pot surface is very sure. In addition , Higgs boson quality , while BEC in the wave massless . Discovered Higgs boson, can not confirm that we live in the BEC . There are no large pot of porridge porridge also maybe .

Baby Cat : We southerners believe that the universe was originally a pot of rice gruel .
I do not know what the reason, the inside of the particles even become a long line , it becomes a bridge noodle .

There Ah : very interesting idea. By observing the universe , testing this idea is correct. I have become a
bridge noodle rice gruel calculate quantum phase transition , and the observable predictions.
