semantic nuance Posted December 9, 2005 at 06:52 AM Report Posted December 9, 2005 at 06:52 AM check http://en.wikipedia.org/wiki/Worldline Once agin, can you give more details of the context you want to use it? You know it differs when you use it in different contexts. Hope it helps! Quote

skylee Posted December 9, 2005 at 10:37 AM Report Posted December 9, 2005 at 10:37 AM Take a look -> 愛因斯坦的時空觀 (this is a webpage of the National Science Council of Taiwan) 綜上所述,在狹義相對論中,時間及空間緊密地結合在一起,共同構成四維的閔氏空間,但這四維時空仍是平坦的。物體的運動描出在這四維時空中的世界線(world-line),若無外力作用,則物體作等速度的慣性運動,對應的世界線則是四維閔氏空間中的直線。 As to explanation, this might help -> 那么,究竟什么是“世界线”?我们知道,一切物体都是由粒子构成的,如果我们能够描述粒子在任何时刻的位置,我们就描述了物体的全部“历史”。想象一个由空间的三维加上时间的一维共同构成的四维空间。由于一个粒子在任何时刻只能处于一个特定的位置,它的全部“历史”在这个四维空间中是一条连续的曲线,这就是“世界线”。一个物体的世界线是构成它的所有粒子的世界线的集合。“世界线”意味着所有粒子的历史已经给定,再也不会被改变。事件一旦发生,即表明身体上的每一个原子的世界线都已经固定,无论我们再做什么都不会重新改变。即使那个不及格的孩子能够再次回到考场,他所能做的也只有重复错误,再考一个59分;即使你能够预先知道下周会挨老板骂,你到时候还是会在预定的时间犯预定的错误,那顿骂是无论如何免不了的。 不仅粒子的历史可以构成世界线,一些人为定义的“东西”的历史也可以构成世界线,比如说影子和光斑。这些点虽然不是真正的粒子,但它们是由真实的粒子来决定的,因此它们的“历史”也构成世界线。 Quote
LiYuanXi Posted December 14, 2005 at 03:18 AM Author Report Posted December 14, 2005 at 03:18 AM Thanks so much!! You guys are real good at sourcing for stuff like this. I have been surfing the web for more than an hour trying to find a translation but I didn't find anything that fits. I am discussing this topic with my teacher who can't speak english so I have to find a translation for 'worldline'. Thanks!!! Quote
