quark

This tree here doesn't look very mathematical at first sight, but if we look really closely at this bark, it's made of cells, that are made of molecules, that are made of atoms, that are made of quarks and electrons, and as far as we can tell, neither the electrons nor the quarks, nor any of the other particles that make up all of this have any properties at all, except for mathematical properties.

第一眼看去 这棵树也不像是数学的 然而如果我们仔细看这块树皮 它是由细胞构成的 细胞由分子构成 分子由原子构成 原子由夸克和电子构成 据我们所知 无论是电子还是夸克 还是构成这些的其它任何粒子 除了具有数学上的性质之外 不具备别的任何性质

We'll be discussing deriving nuclear physics from the quark model.

我们会谈到从夸克模型推导核子物理

We can ignore the particle masses at the individual quark level.

我们可以忽视在单夸克级别的 粒子质量

A primary feature of quarks is that they're always bonded together, but in that moment, I felt like a neutrino, destined to be alone forever.

夸克的主要特点是 它们总是紧密结合在一起 但在那一刻 我觉得自己是颗中微子 注定永远孤独

They might have other strange collections of quarks that combine in some strange way and create more complicated forms that can form life in physics students.

他们也许有其他奇异的夸克集合 以某种奇怪的方式结合在一起 创造出更加复杂的形式 甚至可以形成有生命的物理学生
