2012年,在原子核物理課上,代課的老師說了一段話:“我覺得Higgs是不可能找到的,因為從來沒有過基本標量粒子?,F(xiàn)在找到的標量介子都不是基本粒子?!?br>同年7月份,我坐在電腦前,看了CERN找到Higgs的發(fā)布會。
科研的信念就是這么神奇。幾十年的尋找都不曾有結(jié)果,人們紛紛放棄的時候,它突然就出現(xiàn)了。
Particle Fever這個電影,更多的是從ATLAS實驗的角度講了Higgs的發(fā)現(xiàn)之旅,不過它的兄弟實驗CMS同樣有著非常精彩的故事。
粒子物理是一個需要大量理論背景才能搞懂的東西
“星空中,群星燦爛,那聽不見的樂曲充滿整個宇宙”這是劉慈欣在他的短篇小說微觀盡頭中的一句話。小說里的物理學(xué)家和影片中的物理學(xué)家一樣面對著未知的恐懼。他們不知道粒子撞擊后會發(fā)生什么,有可能實驗的數(shù)據(jù)會推翻之前人類所有的物理定律,有可能人類對這個世界的基礎(chǔ)認知全部崩塌,甚至有可能毀滅了整個世界。這是一場用全體人類的未來做賭注來和上帝賭博的一場游戲。但是最后我們贏了,他們證明了超統(tǒng)一理論中的變量,而我們找到了希格斯粒子。
有幾個在影片中讓我感到影響深刻,甚至有點恐怖的點。
The documentary is about the ups and downs of CERN LHC (Large Hadron Collider) during its first days of proton collision experiments. But ultimately this is not a story about physics, rather about the human spirit.
Many moving moments: when the scientists talked about why they chose physics as their career, it is all very philosophical. In their different ways, they all want to grasp something concrete in order to understand the universe, the eternity.
The two grey haired theoretical physicists discussing the possibility of the outcome of LHC experiment could prove the theory they had worked on all their career wrong. As an audience, you can clearly see, to them, how devastating this could be. At the end of the discussion, however, they agreed, the truth is the most important thing.
粒子狂熱:人類的針尖兒與人類的智慧。
