Royal Society meeting on Physics & Mathematics of String Theory (contd.)

25:00 Now, this will also be a unitary representation because it's just a subspace. Now, this discussion can be generalized to lots of interesting n equal 2.

27:30 So, the idea is that at n equal 1, this operator product, I've chosen as a convenient normalization to put the level k representation. It's the notation of J sub, the topoxeter number of the group.

30:00 In general, such a model, just as n equal 2 is going to go into, if in this way you form a hypersurface with three complex dimensions, then it turns out that the vanishing of the first term class, which is what you need for it to be allowed in the alphabet, is exactly the statement that the...

50:00 All of these nice features emerge in a rather natural way. It doesn't involve that much making special choices.

52:30 So I'm optimistic that even though string theory is strongly coupled, that a classical solution could turn out to be useful, and if we have a complete classification, then all we have to do is go down a list and see if any one of them really does work. The ultimate non-perturbative question is, why is there a vanishing cosmological constant? I prefer to reformulate the question as saying, when the non-perturbative effects break supersymmetry, why don't they give rise to a cosmological constant at the same time? Well, I don't know the answer to that question. I feel in my bones that the answer must involve long-scale physics. Since I just arrived, I guess I'm allowed to ask a question. As you know, in order to have space-time supersymmetry, it's not necessary to have 2.2 supersymmetry on the world sheet, as there'd be any recent progress towards quantification of that sort.

55:00 Let me just remark that there's some interesting work that I didn't have time to talk about with John Ellis and his negotiators, involving his team on a flip that you thought, which I would draw to your attention, I think is potentially very interesting. What is it going to be that these classical solutions you're obtaining are actually stable solutions? Can you think of any? And these solutions which you are obtaining by Calabrian compactification, what's it going to be that actually they are going to be stable kind of solutions? Well, the question of stability, of course, involves a non-perturbative effect. The hope is that when we compute the non-perturbative effect, We'll find that the potential to evolve depends on the moduli of the algebras, in such a way that a particular point would be picked out as energetically favorable. There could also be effects involving tunneling between different possible solutions, but I'm wondering if David Gross' work showing string perturbation expansion doesn't converge is sort of indirect evidence for that kind of thing. So I think we hope that what you suggest could happen, does happen, that having this enormous proliferation of classical solutions is an embarrassment, and if you ask what might reduce the number, theoretically rather than just by comparing with experiments, I think the best hope resides in that kind of thing, I'd say. Any other questions?

57:30 No, I think... Yes, all right. Can we have the microphone mic here, please? Since you mentioned the recent work by Lutcombe, since Lutcombe is here, since you couldn't tell us what he has done, maybe he could tell us what he has done. We approached this from a geometric point of view and constructed signal models which have Calabria target spaces. And it includes a natural choice of kinetic terms, which you do not see in the approach. The connection to Geithner is not entirely true. Well, before we finish, I think we should welcome Ed Witten back again. Sorry that it wasn't quite the time to give a talk about him, but you will hear his talk in the ascent that Mr. Schwartz was looking for in the moment. Thank you very much again.

1:00:00 Thank you for your attention. Thank you for watching. Thank you for your attention. Thank you for watching. Thank you for your attention. Thank you for your attention. Thank you for your attention.

1:02:30 Thank you for your attention. Thank you for your attention. Thank you for watching. Thank you for watching. Good morning, welcome to my head. I look at myself. That's very cool. Thank you for your attention.

1:05:00 Thank you very much for your attention. I was thinking of the other John Bell. I mean, no, I was thinking of our John Bell. James Cameron? Yeah, well, not James Cameron. How is he? Very low. Still the same? No change? Well, it's about ten days since I saw him. He does get very depressed. Oh, that was after I... So you haven't seen him since I last saw you? No, that seems to have passed for you. It was only a week since I saw you. Michael Green, I guess. No, sorry, I'm about ready. Why don't you grab one of those? Yeah. No, they've got all three of them. We don't need them at all. Try and sit on the stool, because he's a small one. Sit at your feet, isn't it? Sit at your feet. Well, I say Chaldea, it's an out-held at the end, you know, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, Chaldea, I just said I'd love to be there, but I'm going to be a monster.

1:07:30 This is probably an academy of science, isn't it? Thank you for watching. Thank you for your attention. Thank you for watching. Thank you for watching. Thank you for your attention. Thank you for watching. Thank you for watching.

1:10:00 Thank you for your attention. I'd love to go back now, but I haven't. Where they all go and, you know, do what they used to do in Regents Park. I'm going to get a combined Christmas dinner. And I don't normally kill time, I don't really animate in the video. It's a kind of joke, but I definitely don't kill. You always say, you know, with a camera out in front of you, why the hell did you ever hit me? So he's there now, so he's about the 3rd or 4th of February. And so far for the morning, it's in 1980. It's a freeze, and I've got some terrestrials. The hostages on the area of my flight are incredible. Thank you for watching. Thank you for watching. Thank you very much for your attention.

1:12:30 I had to be over there. I had to be over there. I don't know if it's going to happen, but I don't know if it's going to be a lunch.

1:17:30 Good hotel guys. That's right. Have it delivered again for a five-hour. They've got hospitals. They've got hospitals. They've got hospitals.

1:20:00 They've got hospitals. They've got hospitals. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one.

1:22:30 Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one. Oh, there's a second one.

1:25:00 Oh, there's a second one.
