Dirac also remained true to Werner Heisenberg, a German physicist suspected of being a Nazi sympathiser.

而纳•海森堡也一直忠心耿耿，后者曾被怀疑纳粹分子抱有同情。

Heisenberg's uncertainty principle, according to which nature is inherently indeterministic, implies an open future (and, for that matter, an open past).

在海森堡测不准原理中，自然在本质上是不可定，这意味著未来是开、不定（以此观点而论，过去也是开）。

The best clocks now scan a one-hertz-wide sweet spot to find its exact center, plus or minus one millihertz, in every single measurement—despite the Heisenberg limits.

尽管有海森堡限制存在，目前最好时钟每次测量时都直接扫描一赫兹宽「好球区」，以找出中心，误差只有一毫赫兹。
