But neither can be said to actually be true.
但其實這兩者都不能算是真的
Because they,like all models,are just a models in our heads:
因為它們就像所有模型一樣 只是我們想象出來的
The best fit of reality we perceive.
最符合我們所認知的現(xiàn)實世界
In fact,physicist are forever creating ever more sophisticated models
事實上 物理學(xué)家不斷建立更精密復(fù)雜的模型
And the truth of those models is impossible to establish.
而我們無法證實那些模型的真實性
A good example of this came in the 1960s.
1960年代出現(xiàn)了一個很好的例子
Physicists devised a theory of really tiny bits of matter,called Quarks.
當時物理學(xué)家建構(gòu)了一套理論 有關(guān)一種極微小物質(zhì)的 叫做 夸克
These quarks were proposed to be the building blocks of the subatomic particle called:A proton.
根據(jù)理論 夸克是一種亞原子粒子的組成單元 那種粒子就是質(zhì)子
The theory our model suggested that
該理論或模型主張
these quarks were held together by a force
夸克被一種力量連結(jié)在一起
that got stronger as you tried to separate them.
當你越想分離夸克 力量則越大
If the quarks were bound by tiny rubber bands.
仿佛夸克被小小的橡皮筋綁在一起
This model also implied that there is no way one can ever see a single isolated quark.
這個模型同時指出 人絕對無法看到單一孤立的夸克
At first,some people were skeptical.
起初有些人抱持懷疑的態(tài)度
If something by its very definition can never be seen,
若根據(jù)事物本身的定義 我們無法觀察到它
Can it be said to exist?
這樣還能說它存在嗎？
Does it make sense to say that quarks are real or not?
那么討論夸克是真是假有意義嗎？
