Since the Dirac-Feynman path integral formalism is completely equivalent to the Heisenberg formalism, it most certainly contains the uncertainty principle.

you think I’m going to explain it to you so you can understand it? No, you’re not going to be able to understand it. Why, then, am I going to bother you with all this? Why are you going to sit here all this time, when you won’t be able to understand what I am going to say? It is my task to convince you not to turn away because you don’t understand it. You see, my physics students don’t understand it either. That is because I don’t understand it. Nobody does.

我好像是第一次看书的时候看 foreword preface 和 introduction 这么认真，因为我怀疑正文我都看不懂

Every particle in Nature has an amplitude to move backwards in time, and therefore has an anti-particle. […] I’d like to show you what this backwards-moving electron looks like to us, as we move forwards in time. […] We start at T0 with an electron moving toward a photon, which is moving in the opposite direction. All of a sudden—at T3—the photon turns into two particles, a positron and an electron. The positron doesn’t last very long: it soon runs into the electron—at T5, where they annihilate and produce a new photon. Meanwhile, the electron created earlier by the original photon continues on through space-time.

所以，电子是真的进行了时光倒流，只不过在随着时间正向流动的人眼里看来就成了正电子吗还是说这是一个假说/理解方程的角度？
