|
|
|
4 It's of my eye, which being that whatever I focus on goes blurry.
|
|
|
5
|
|
|
6 [Speaker 1] (0:11 - 0:16)
|
|
|
7 And my mobile phone camera has that problem.
|
|
|
8
|
|
|
9 [Speaker 2] (0:17 - 0:21)
|
|
|
10 Well, so that might be true of attention, too.
|
|
|
11
|
|
|
12 [Speaker 1] (0:22 - 0:22)
|
|
|
13 Yeah.
|
|
|
14
|
|
|
15 [Speaker 2] (0:23 - 0:23)
|
|
|
16 Anyway.
|
|
|
17
|
|
|
18 [Speaker 1] (0:28 - 0:39)
|
|
|
19 We should probably, in the interests of your stamina, if not mine, bring this to a close for now and let you spend a little more time on reflection before.
|
|
|
20
|
|
|
21 [Speaker 2] (0:40 - 0:41)
|
|
|
22 Before collapsing.
|
|
|
23
|
|
|
24 [Speaker 1] (0:42 - 0:46)
|
|
|
25 Before you, yeah, exactly. Turn to.
|
|
|
26
|
|
|
27 [Speaker 2] (0:46 - 0:47)
|
|
|
28 At any rate, Agri.
|
|
|
29
|
|
|
30 [Speaker 1] (0:48 - 0:52)
|
|
|
31 Yes, there you go, Phil Agri. Well done. You see, it took you 90 seconds.
|
|
|
32
|
|
|
33 [Speaker 2] (0:52 - 1:00)
|
|
|
34 I know. It was obvious.
|
|
|
35
|
|
|
36 [Speaker 1] (1:01 - 1:03)
|
|
|
37 What about him? It was obvious to him, yes.
|
|
|
38
|
|
|
39 [Speaker 2] (1:03 - 1:15)
|
|
|
40 Yeah, I remember saying it to him and he said, oh, yeah, of course, that's right. And in fact, the model that he takes to underwrite whatever he's famous for, is it Pangea? I can't remember.
|
|
|
41
|
|
|
42 [Speaker 1] (1:16 - 1:27)
|
|
|
43 Yeah, I mean, well, it's the revolution in planning, which I used to have to teach, which I used to be able to teach about and have now for the people have lost sight of. I mean, planning isn't a thing anymore.
|
|
|
44
|
|
|
45 [Speaker 2] (1:28 - 1:28)
|
|
|
46 No, that's right.
|
|
|
47
|
|
|
48 [Speaker 1] (1:28 - 1:43)
|
|
|
49 I don't think I could point to a single one of my 120 colleagues at Edinburgh, the largest AI establishment in Europe and say that since Austin Tate retired and said, say that they work on planning.
|
|
|
50
|
|
|
51 [Speaker 2] (1:43 - 1:43)
|
|
|
52 Yeah.
|
|
|
53
|
|
|
54 [Speaker 1] (1:44 - 1:55)
|
|
|
55 I mean, if there's reinforcement learning, but that's only planning by courtesy or post hoc.
|
|
|
56
|
|
|
57 [Speaker 2] (1:57 - 1:58)
|
|
|
58 It's interesting, Xander is a planner.
|
|
|
59
|
|
|
60 [Speaker 1] (2:01 - 2:04)
|
|
|
61 In terms of his job title, yes.
|
|
|
62
|
|
|
63 [Speaker 2] (2:04 - 2:06)
|
|
|
64 Right, well, in terms of what he does.
|
|
|
65
|
|
|
66 [Speaker 1] (2:07 - 2:07)
|
|
|
67 Yeah, yeah, no, I know.
|
|
|
68
|
|
|
69 [Speaker 2] (2:08 - 2:10)
|
|
|
70 It's urban planning, but hold the urban.
|
|
|
71
|
|
|
72 [Speaker 1] (2:13 - 2:28)
|
|
|
73 Well, I mean, that's what Catherine, who's back there somewhere, I think. Yes. Absolutely.
|
|
|
74
|
|
|
75 The design of the non-built environment.
|
|
|
76
|
|
|
77 [Speaker 2] (2:28 - 2:28)
|
|
|
78 Right.
|
|
|
79
|
|
|
80 [Speaker 1] (2:32 - 2:33)
|
|
|
81 Defined privatively.
|
|
|
82
|
|
|
83 [Speaker 2] (2:34 - 3:01)
|
|
|
84 Here's a question which I thought about once and I was sort of struck by it, which is, if England were to decide one day to switch overnight to driving on the right instead of driving on the left, I believe the following proposition is true, which is the roads would be fine as is. What would have to change is an awful lot of signage.
|
|
|
85
|
|
|
86 [Speaker 1] (3:05 - 3:25)
|
|
|
87 And it's interesting question, at least some traffic lights, but that is so there would have to be, some things would have to be physically moved as well as the content of some. Well, indeed, some signs would have to be moved, right? They would be in the wrong place.
|
|
|
88
|
|
|
89 [Speaker 2] (3:26 - 3:27)
|
|
|
90 They'd be in the wrong place.
|
|
|
91
|
|
|
92 [Speaker 1] (3:27 - 3:38)
|
|
|
93 No, the stop signs, you know, a stop sign, which is to your right as you come to a stop would have to be moved. Right. Sorry, to your left.
|
|
|
94
|
|
|
95 [Speaker 2] (3:38 - 3:39)
|
|
|
96 Yeah.
|
|
|
97
|
|
|
98 [Speaker 1] (3:40 - 4:52)
|
|
|
99 I mean, maybe you're just remembering this because it might well have been you who told me this order 45 or 50 years ago, which is that two particular points about the early days of the systems theory class at MIT, both of them about examining the systems theory class, that the final year project was to describe in as much accurate detail as possible the algorithm implemented by the tech square elevators without using an oscilloscope. And the other was to, you know, produce a succinct, whether it was a project or actually an exam question, which is to produce the too long didn't read three page outline of what the Swedish government needed to do to do exactly that, because they have.
|
|
|
100
|
|
|
101 [Speaker 2] (4:53 - 4:58)
|
|
|
102 Right, right, right, right. No, these are not, none of this rings a bell.
|
|
|
103
|
|
|
104 [Speaker 1] (4:58 - 5:56)
|
|
|
105 So, okay. Well, yeah, someone else, but exactly. So, so, okay.
|
|
|
106
|
|
|
107 Sorry. But, but so the point of the fact that the, you know, stipulate that we had somehow managed to evolve our traffic system without ever actually asphalting any tarmac. And, and so the paths were just the consequence of our driving.
|
|
|
108
|
|
|
109 That, that none of the, nothing, nothing of the non-human world would need to change. People would find it inconvenient that their steering wheel was on the side that it was on. But the fact that I drove in this country, and so did Catherine drive the Saab that I brought to California for many years is, you know, that's not.
|
|
|
110
|
|
|
111 [Speaker 2] (5:56 - 5:57)
|
|
|
112 Testament to something.
|
|
|
113
|
|
|
114 [Speaker 1] (5:58 - 6:02)
|
|
|
115 Well, it's a testament to something, but it's also, it doesn't, it doesn't falsify the claim.
|
|
|
116
|
|
|
117 [Speaker 2] (6:03 - 6:03)
|
|
|
118 Right.
|
|
|
119
|
|
|
120 [Speaker 1] (6:03 - 6:48)
|
|
|
121 No human artifacts would need to change to adapt to this. But, but the question of whether you could, well, if you use, if, if, so we could, we could articulate this further, right? You have to suppose that in the absence of any signage or any traffic signals that rotaries had to evolve because rotaries enable you to efficiently have crossroads with, without any, you know, without any overt control of flow.
|
|
|
122
|
|
|
123 But no, but hang on a second.
|
|
|
124
|
|
|
125 [Speaker 2] (6:48 - 6:50)
|
|
|
126 The ovaries, I mean, the ovaries, the rotaries.
|
|
|
127
|
|
|
128 [Speaker 1] (6:51 - 6:57)
|
|
|
129 I'm sorry. We won't go there. Strike that from the record, your honor.
|
|
|
130
|
|
|
131 [Speaker 2] (6:59 - 7:04)
|
|
|
132 The rotaries in Sweden have the following property, which is their spirals.
|
|
|
133
|
|
|
134 [Speaker 1] (7:07 - 7:17)
|
|
|
135 So you enter and depending on how far you're going, you go further in.
|
|
|
136
|
|
|
137 [Speaker 2] (7:18 - 7:28)
|
|
|
138 That's right. Because that's right. Because if you're going to get off at the farthest exit to the rotary, you move into the center.
|
|
|
139
|
|
|
140 [Speaker 1] (7:29 - 7:36)
|
|
|
141 Yeah. Well, all, all big rotaries in the UK are like that now, but they're, but they're marshaled by lines on the pavement.
|
|
|
142
|
|
|
143 [Speaker 2] (7:37 - 7:48)
|
|
|
144 Right. But you, you, once you got yourself in the right lane, then it dumps you off at a certain exit.
|
|
|
145
|
|
|
146 [Speaker 1] (7:49 - 8:05)
|
|
|
147 No, it doesn't. That's what's interesting because the lines just take you into the center. You have to then cut across the lines that are taking somebody else into the center to get off when you want to get off.
|
|
|
148
|
|
|
149 [Speaker 2] (8:05 - 8:07)
|
|
|
150 Well, that's the opposite of Sweden, I believe.
|
|
|
151
|
|
|
152 [Speaker 1] (8:09 - 8:18)
|
|
|
153 Well, I'm sorry. You have to, you have, you, I, my immediate thought is you can't not have potential crossings.
|
|
|
154
|
|
|
155 [Speaker 2] (8:20 - 8:26)
|
|
|
156 No, you, but, but they happen right when you get in. You, when you get into the rotary, you cross it.
|
|
|
157
|
|
|
158 [Speaker 1] (8:26 - 8:29)
|
|
|
159 As you get in, you're crossing people who are on their way out.
|
|
|
160
|
|
|
161 [Speaker 2] (8:30 - 8:30)
|
|
|
162 Right.
|
|
|
163
|
|
|
164 [Speaker 1] (8:31 - 8:31)
|
|
|
165 You must be.
|
|
|
166
|
|
|
167 [Speaker 2] (8:32 - 8:32)
|
|
|
168 Yes.
|
|
|
169
|
|
|
170 [Speaker 1] (8:32 - 8:55)
|
|
|
171 No, absolutely. So you can't, you, you can, you can only have, you, you have to, if you're going to put lines on the pavement that indicate priority, they can only deal with, with, they have to give that priority unequivocally at every intersection. And so you have to decide who has priority, people coming in or people going out.
|
|
|
172
|
|
|
173 [Speaker 2] (8:56 - 8:58)
|
|
|
174 Right. And you pretty much have to decide people going out.
|
|
|
175
|
|
|
176 [Speaker 1] (8:59 - 9:03)
|
|
|
177 Because, except I, yeah, I guess. Yes.
|
|
|
178
|
|
|
179 [Speaker 2] (9:03 - 9:07)
|
|
|
180 Otherwise you might end up with a logjam of people in the rotary.
|
|
|
181
|
|
|
182 [Speaker 1] (9:08 - 9:35)
|
|
|
183 I need to, I need, I need to, there is a rotary that I don't like going on, on the bike precisely because as a cyclist, when you have to cross the line of priority, you're vulnerable because people assume you're going slower. They don't even see you. Anyway.
|
|
|
184
|
|
|
185 Anyway. Sorry. I was entertaining ourselves without actually moving ourselves forward.
|
|
|
186
|
|
|
187 [Speaker 2] (9:36 - 10:11)
|
|
|
188 Yeah. So, okay. So I think what I wanted to say by way of summary is, is there a feasible project, God willing, in the Creekstone rise to have a shortish version of this story that tells these two stories.
|
|
|
189
|
|
|
190 [Speaker 1] (10:14 - 10:15)
|
|
|
191 We can but try.
|
|
|
192
|
|
|
193 [Speaker 2] (10:16 - 10:52)
|
|
|
194 We can but try. And I think a subsidiary question to that is, can I, and my answer might be no. Can I come up with an F-able description of why the Dijkstra's generates, why the physical Dijkstra's generates linguistic indexicals?
|
|
|
195
|
|
|
196 That's simple.
|
|
|
197
|
|
|
198 [Speaker 1] (10:53 - 10:55)
|
|
|
199 That's already a better way of putting it. Carry on.
|
|
|
200
|
|
|
201 [Speaker 2] (10:56 - 11:21)
|
|
|
202 Yeah. No, I think, I mean, that's all I would want to say. And is that story essential to the fusion, as it were, that this project is aiming at?
|
|
|
203
|
|
|
204 I don't think those are questions that I'm not going to try to answer them now. And I don't think, I can't answer, I can't do anything until the reflections book is done.
|
|
|
205
|
|
|
206 [Speaker 1] (11:22 - 11:25)
|
|
|
207 Understood. But those are questions we can pick up then.
|
|
|
208
|
|
|
209 [Speaker 2] (11:25 - 11:27)
|
|
|
210 Well, but also there, they can be mulled on.
|
|
|
211
|
|
|
212 [Speaker 1] (11:28 - 11:29)
|
|
|
213 Yeah, absolutely.
|
|
|
214
|
|
|
215 [Speaker 2] (11:30 - 11:30)
|
|
|
216 Before then.
|
|
|
217
|
|
|
218 [Speaker 1] (11:33 - 11:47)
|
|
|
219 And there was something moderately important there that just slipped. What was it? Oh, yes.
|
|
|
220
|
|
|
221 It also occurs to me that there's a, just, I just want to get this on the record and we can Yeah, sure.
|
|
|
222
|
|
|
223 [Speaker 2] (11:47 - 11:47)
|
|
|
224 Say goodbye.
|
|
|
225
|
|
|
226 [Speaker 1] (11:48 - 12:48)
|
|
|
227 There's a, there's a, a trick that, that Feynman pulls in what I think is the, the best thing that he ever wrote, which is his, his book about why glass is transparent, which has a title, which has quantum something in it, but I can't remember now. Doesn't matter. It's only about this.
|
|
|
228
|
|
|
229 It's only, it's less than a centimeter thick. When you think of it, give me a note. And it, what he, what he says in the introduction is that the characteristically Feynman introduction, because he says the thing I hate about popular science is they don't tell you when they're lying to you.
|
|
|
230
|
|
|
231 [Speaker 2] (12:48 - 12:49)
|
|
|
232 Right.
|
|
|
233
|
|
|
234 [Speaker 1] (12:50 - 13:39)
|
|
|
235 Because they have to lie to you because to tell you the truth would mean that they would, they'd exceed their word count. Right. Right.
|
|
|
236
|
|
|
237 And newspaper editors are very jealous of people, you know, their word count. And there is a point in this book in which I'm going to lie to you and I'm going to tell you when we get there so that you know it. Okay.
|
|
|
238
|
|
|
239 Because it's the one point in the book where I think people with a reasonable grasp of moderately sophisticated mathematics to the degree of a high school diploma and maybe a little bit of calculus can understand. But there's one point at which I'm, that, that's blown. And I'm, so I'm going to lie to you and I'll tell you.
|
|
|
240
|
|
|
241 [Speaker 2] (13:40 - 13:41)
|
|
|
242 That's what Feynman says.
|
|
|
243
|
|
|
244 [Speaker 1] (13:42 - 14:35)
|
|
|
245 That's what Feynman says in the introduction. And he does indeed at some point in the book tell you. And the, the version of that, that might apply is to, to go back to a rhetorical stance, which you adopted briefly 20 or 30 years ago.
|
|
|
246
|
|
|
247 And I think correctly, subsequently abandoned, which is the promissory, you know, where, where your version of that was, who, who, who needs to accept what promissory notes in the course of, you know, when am I uttering promissory notes, which I'm not delivering on? The similar phenomenon. I think it's in the objects book that you, in the, the preface of the objects book that you, you articulate a sort of epistemological stance about the necessity of being clear when promissory notes are being uttered.
|
|
|
248
|
|
|
249 [Speaker 2] (14:36 - 14:36)
|
|
|
250 Right.
|
|
|
251
|
|
|
252 [Speaker 1] (14:36 - 15:07)
|
|
|
253 A sort of lighter weight. And, and, and even in the, in the sense of, of Feynman being humor, being constantly lurking around the edges. Right.
|
|
|
254
|
|
|
255 That, that may be the way to get a 50 page draft of the 4,000 page pair of parallel drafts is to, is, is simply to put square brackets. Magic happens here.
|
|
|
256
|
|
|
257 [Speaker 2] (15:08 - 15:08)
|
|
|
258 Right, right.
|
|
|
259
|
|
|
260 [Speaker 1] (15:09 - 15:09)
|
|
|
261 Ad lib.
|
|
|
262
|
|
|
263 [Speaker 2] (15:11 - 15:11)
|
|
|
264 Yeah.
|
|
|
265
|
|
|
266 [Speaker 1] (15:12 - 15:17)
|
|
|
267 And fill them in as time allows.
|
|
|
268
|
|
|
269 [Speaker 2] (15:18 - 15:19)
|
|
|
270 The time allows, yeah.
|
|
|
271
|
|
|
272 [Speaker 1] (15:19 - 15:24)
|
|
|
273 The point at the very least, not to, not to, to run into the sand at those points.
|
|
|
274
|
|
|
275 [Speaker 2] (15:24 - 15:47)
|
|
|
276 Right, right, right. Another way to do it is to, is to put together lecture notes for my class, which I regularly did and compressed an enormous amount of whatever. I mean, that was a discipline that came pretty easily getting in, didn't bog down.
|
|
|
277
|
|
|
278 [Speaker 1] (15:48 - 15:49)
|
|
|
279 Yeah. Yeah.
|
|
|
280
|
|
|
281 [Speaker 2] (15:49 - 15:50)
|
|
|
282 So.
|
|
