Born to do Math 60 – Sum Over Histories

Scott Douglas Jacobsen & Rick Rosner

May 5, 2017

[Beginning of recorded material]

Rick Rosner: It is also something that you can physics without. You cannot do quantum physics without quantum indeterminacy. That systems exist in states where there is not enough information to define some aspects of that system. But that doesn’t mean that you have to see everything through the lens of multi-worlds theory. There are probably other theories that have the same deal. String theory may become a more powerful tool for describing the world.

But right now, it hasn’t delivered enough specific predictions to be very useful. But at some point in the future, string theory could be worked out in the future into a framework that might be helpful in certain instances. There’s a Sum Over Histories of Feynman that says quantum particles take every possible path between point A and point B. That’s a helpful framework for doing certain quantum tasks.

If you’re sufficiently trained in quantum mechanics, you may have that in the back of your mind, but you don’t always need the Sum Over Histories principle to do quantum mechanics. None of which gets to the reason we exist, and why we exist in the ways that we exist. That is, three spatial dimensions roughly with an asterisk and that asterisk being quantum effects, quantum foam, a certain number of small scales, and the curvature of space at larger scales. One temporal dimension there too.
