Poincare真的後來有提出那二大假設,在一場演說裡面他就說到這二個假設是相對論 最重要的,但是不知道如何就是沒有推出相對論,可能是乙太一直圍繞著他?所以相對論 一般大家只會公認是愛因斯坦的,因為要想出相對論實在是太難了吧,其他的很多人幾乎都 是臨門一腳,就是無法得知真正物理意義,相對論物理否定牛頓對當時的人太深太前衛了 wiki看到的,至於他的Poincare群,我是不知道怎麼用在相對論 我是在場論看過和學到的,Poincare群應該是比較常用在場論,還有一個真實故事 Poincare是被提名諾貝爾獎最多次的數學家,一直到死為止,可惜一直沒有成功, 不然他可能是人類得到最多榮譽和獎項的數學家,就差這一個在當時大滿貫 Poincare as a philosopher was interested in the "deeper meaning". Thus he interpreted Lorentz's theory and in so doing he came up with many insights that are now associated with special relativity. In The Measure of Time (1898), Poincare said, " A little reflection is sufficient to understand that all these affirmations have by themselves no meaning. They can have one only as the result of a convention." He also argued that scientists have to set the constancy of the speed of light as a postulate to give physical theories the simplest form.[10] Based on these assumptions he discussed in 1900 Lorentz's "wonderful invention" of local time and remarked that it arose when moving clocks are synchronised by exchanging light signals assumed to travel with the same speed in both directions in a moving frame. 還真找到Poincare的文章 有空再看>< http://www.physicsinsights.org/poincare-1900.pdf http://en.wikisource.org/wiki/On_the_Dynamics_of_the_Electron_(June) http://en.wikisource.org/wiki/On_the_Dynamics_of_the_Electron_(July) 剛剛太累只看給Lorentz的信,1905 他似乎也快找出來了 有時間再詳細看>< --
