一、Despite the city's traditional image, many residents never set foot inside a beer hall or go anywhere near Oktoberfest, which is looked down on by some as a festival only for foreign tourists. These citizens see themselves as part of a thriving, modern metropolis which is the high-tech capital of Germany. Indeed, Munich plays host to a large concentration of communications and electronics firms.

尽管慕城具有这种传统的形象，许多当地居民却从未涉足啤酒厅和到举办“啤酒节”临近的任何地方。有些人认为这些地方不屑一顾，只不过是外国游客的节庆。这些市民认为自己是一个蒸蒸日上，现代大都会的一部分。它是德国高科技的首都，的确，慕尼黑接纳了云积此地的众多通讯及电子公司。

二、You cannot change the laws of physics …… but could physics actually enable us to travel through time? It might sound crazy, but according to Einstein's theories, there's no logical reason why time travel isn't possible and there are now scientists looking into it as a serious scientific proposal, at least at a theoretical level.

你无法改变物理学定律……但是物理学能否使我们在时间中旅行呢?这听上去或许像个痴想。但是根据爱因斯坦的理论，时间旅行在逻辑上不是不可能的。现在科学家正把它视为一个严肃的科学命题，至少在理论上如此。

三、Time travel is clearly a trickier proposition than space travel, though. Put simply, Einstein's idea was that every object in the universe has it's own “time”, and these vary as objects move. The faster an object moves, the slower its time is, compared to the time of a slower moving object. The extreme situation would be if an object could move as fast as the speed of light, its time would be completely halted. But whatever an object——or person's——time is, it's only evident in contrast to other objects. In other words, it's all relatives.

与太空旅行相比，时间旅行很显然是一个更为复杂的命题。简而言之，爱因斯坦的观点就是，宇宙中每一物体都有其自身的“时间”，并随其运动的不同而不同。物体运动越快，其时间越慢(与运动较慢的物体相比而言)。最极端的假设是，如果一个物体运动达到光速，那么其时间就会完全停止。但无论一个物体或者一个人的时间为何，它只能参照其它物体才能得以体现。换句话说，万物皆相对。
