德国物理学家维尔纳·海森堡曾经针对量子力学有这样一段表述：”我们必须记住，我们观察到的不是自然本身，而是我们的提问方式揭示的自然。“这并不意味着量子力学是非实在的，而是说，我们赋予量子粒子的不过是经验实在罢了。虽然这听起来有一点非理性，但我们必须意识到，无论在哪个领域，每个人所观察到的很可能只是每个人所关注的东西。换而言之，世界本没有角度，看的人出现了，就出现了角度。
German physicist Werner Heisenberg once wrote, “What we observe is not nature in itself but nature exposed to our method of questioning.” This does not mean that quantum mechanics is unreal, but that what we assign to quantum particles is empirical reality. Though this may sound a little irrational, we have to realize that what everyone observes is likely to be only what everyone pays attention to. In other words, the world does not have any angles of observation, when the [eople who see it appear, angles exist.
