科普:照亮相對論的光 (上)

我在《光的祕密》文中討論了電磁學的發展,以及馬克士威方程如何預言電磁波的存在。但是在 19 世紀末的物理學界仍然存在好幾片烏雲,而且正不斷擴大。其中一片就是牛頓力學與電磁學的結論互相抵觸。

相對性原理 (principle of relativity) 其實並非愛因斯坦所發現的。人類似乎很早就知道 (卻沒有去追問為甚麼,彷彿一切都是必然的) 我們能在行駛中的船上以在地上一樣的力度和角度打桌球、廚師能以在地上一樣的技巧將薄餅拋來拋去、而你也能夠在正以時速 900 公里飛行的飛機上從容不迫地與在地面上一樣做相同的動作。看來,我們習慣所有東西都是理所當然的。懷海德 (Alfred North Whitehead) 說

“It requires a very unusual mind to undertake the analysis of the obvious.”

Faraday

Did you know Michael Faraday was born in a place called Newington Butts? The 10 year old in me was amused at least.

His Faraday Cage has been immortalized in the pop cultural zeitgeist of the 2000s through that ridiculous scene in… 52 more words
