A Portal Special Presentation- Geometric Unity: A First Look: Difference between revisions

<p>[02:14:15] First of all, I think the most important thing to begin with is to ask what new hard problems arise when you're trying to think about a fundamental theory that aren't found in any earlier theory. Now every time you have an effective theory, which is a partial theory, there is always the idea that you can have recourse to a lower level strata.

<p>[02:14:36]

<p>[02:17:03] That which generates, um, all of the content and all of the action, you're, you're left with a puzzle as to how would you move forward from this? It might be easier in a mathematical sense, uh, to temporarily put the U on its back, to put it more in line with a standard picture that many mathematicians and physicists will be familiar with.

<p>[02:17:28] In sector one of the Geometric Unity theory spacetime is replaced and recovered by the observerse contemplating itself. And so there are several sectors of GU and I wanted to go through at least four of them. In Einstein spacetime, we have not only four degrees of freedom, but also a spacetime metric representing rulers and protractors.

<p>[02:20:27] So this is a little bit confusing. One way of thinking about it is to think of the observerse as the stands plus the pitch in a stadium. I think I may have said that in the, in the lecture, but this is what replaces the questions of where and when in the newspapers story that is a fundamental theory. Where and when correspond to space and time.

<p>[02:20:49] Who and what correspond to bosons and fermions. And how and why correspond to equations and the Lagrangian that generates them. So if you think about those six quantities, you'll realize that that's really what the content of a fundamental theory is, assuming that it can be quantized properly. Most fields and in this case, we're going to call the collection of two tuples omega. So the inside of omega that will be in the first tuple will have epsilon and pi written sort of an nontraditional variation of how we write this symbol for Pi. In the second Tuple, we'll have the letters, uh, nu and zeta. And I would like them not to move because they honor particular people who are important.
