If you're in this state, you will necessarily, given the laws of physics and the way the computer's programmed and built and so forth, these wires will turn on, turn off, these circuits will turn on, turn off, boom, suddenly you'll be in that state.

如果你站在这个角度,你必定会考虑,在物理定律和电脑编程原理,如何构造的等等确定的情况下,这些电线通或断,这些回路通或断,嘣,突然你就处在那个位置上
