如何製作MUONS (How To Make MUONS)
02:43
- like muonic hydrogen (with a proton and a muon, instead of a proton and electron).
像muonic氫(質子和一個 μ子,而不是質子和電子)。
- a muon and a neutrino.
一個μ子和一個中微子。
合法的冷核聚變已經存在 (Legitimate Cold Fusion Exists | Muon-Catalyzed Fusion)
06:28
- to achieve muon-aided nuclear fusion at temperatures close to absolute zero.
以在接近絕對零度的溫度下實現μ子輔助核聚變。
- Well, while muon-facilitated fusion is indeed fully legit nuclear fusion at non-crazy temperatures,
好吧,雖然μ子促進核聚變確實是在非瘋狂溫度下完全合法的核聚變。
這種難以捉摸的粒子能否重塑標準模型? (Could This Elusive Particle Reshape the Standard Model?)
05:45
- discovery has thrown a wrench in that. Amanda has muon that here.
發現已經在這一點上拋出了一個扳手。阿曼達在這裡說過。
愛因斯坦的狹義相對論|時間真的會變慢嗎? (Einstein’s Special Relativity Theory | Does Time really Slow down)
13:15
- Another experiment was conducted with the lifetime of a muon.
另一項實驗是針對μ介子的壽命進行的。
- That's when muon particles are in motion, and they take longer to break apart.
這時μ介子粒子處於運動狀態,它們需要更長的時間才能分裂。
不可能的μ子 (Impossible Muons)
04:34
- Oh yeah, the greek symbol, mu is both used for “muon” AND for “microsecond”,
哦,對了,希臘符號mu既是 "μ子 "的意思,也是 "微秒 "的意思。
- would be ~22 microseconds for us , enough time for the average muon to travel at least
對我們來說,將是〜22微秒,足夠時間為平均μ子旅行至少

- Then we discovered, all the way back in the 1930s, a heavier cousin of the electron. This is called the muon. And famously, there was a physicist at Columbia, I. I. Rabi, who said, who ordered that? We did not know why the electron needed to have a heavier cousin involved. But now we know it's because this idea of the two quarks, up and down, and the two non-quarks, which we now call leptons, the electron and the neutrino, that pattern is repeated two more times. So there are three families of particles. There's the up quark and the down quark. But then there's heavier cousins, the charm quark and the strange quark. And even heavier cousins, the top quark and the bottom quark.
然後,我們在 20 世紀 30 年代發現了電子的一個更重的表親。這就是μ介子著名的是 哥倫比亞大學的物理學家 I. I.I. 拉比,他說,這是誰定的?我們當時不知道 為什麼電子需要有一個更重的表親參與進來但現在我們知道了 這是因為兩個夸克的概念 向上和向下 還有兩個非夸克 我們現在稱之為輕子 電子和中微子所以有三個粒子家族有上夸克和下夸克但還有更重的表親 粲夸克和奇異夸克還有更重的表親 上夸克和下夸克
- And then on the lepton side, we have the electron and a neutrino associated with the electron, which we cleverly call the electron neutrino. We have the muon, its heavier cousin, and a muon neutrino. And then we have a tau particle, which is heavier than the muon, and a tau neutrino. Six quarks, six leptons, arranged in three families.
在輕子方面,我們有電子和與電子相關的中微子,我們巧妙地稱之為電子中微子。我們有μ介子,它是更重的表親,還有一個μ介子中微子。還有比μ介子更重的陶粒子和陶中微子。六個夸克 六個輕子 分為三個家族
