 So, I was asked to talk about my experiences of 921st Caden, and he met a very good Berkeley, and that would be a very severe loss. Probably the students were similar. So these are such an interesting thing to be building. And I've always been really great with my biggest persuaded me to stop doing that, and to start doing that, which is much more fun because you're in the outside world, and you can translate behavior pretty easily in what's happening. Well, so we worked on the holidays. And one of the fires he worked on was a restlessness. And if you go into too many woods or arts or anywhere, you can see these things hanging in the air. And every now and then, they make a dance, but hopefully an eight, and very rarely is an eight, so then they come back to the same place. This is a kind of chase. So there it starts, and then it goes very fast, and it goes very slow. So, one thing we wanted about was, that the same place. So we found that. So here's a whole function is chasing and these are the operating points here. And this is the length of the excursion. And there's no relationship between the length of the excursion and how accurate. The same place. So that made us wonder where there's some visual information that they might be picking up around the inside. And we tested that by using a large board that we placed relatively close to where these fires were found. And then we move the board away. And if you look at this you can see the trajectory. So the board is moving during this possible trajectory. And it goes away. That's an useless chase. And then it comes back. The position relative to the board you choose is then is as a similar distance to the machine where the board was here. And this shows it more clearly. You can see that that distance is more it's the same. So we suppose that what happens is that they have learned the size of this board and then they fly back until the image of the board sometimes the same angle that it did when they left. And there are many experiments that we could do to test this more. Finally, but that's as far as we thought. So the next question we had with advice with their status was about their chase itself. How does it control its pursuit of potential bears? And for that we use fish eaters. So the target is a few shots of the fish in there. And here you can see what the fly is doing. So it's not trying to trap because it's going beyond. And this would be if you simulated a tracking course. We could get some experimental evidence for this supposition. So I put in a key at the end of the legs of cotton. And then when the key was shot close to the right, the key stops here. And one is where the fly starts its interception course. This region, there's no visual information at all. And it doesn't start to miss the lack of visual intervention on the right there. So that seems to be reasonable evidence. And so we then looked at a different subject. And we made a sort of ecosystem. There were flowers, and there were flies, and they lived happily in there. And I just thought we could report what we did in this uninterrupted situation. So this is an example of a fly just flying around. And what is really nice is if you look at this bit, you can see that it maintains the same orientation sideways or to do that backwards. And that means that the world itself is stationary on its retina. And it can easily pick up any small target that there is. So all of a sudden, a lot from this precision kind of sideways backwards forwards, upside down the plane. And Mike then went on to look at the eye and he found that the male eyes are very much better. Let's see. And you can see that here. The degree is on a male. Whereas 10 degrees on a female is on that. And they make the males make good use of this additional ability when they interact with humans. So. Here's a male. The question is what it wants to be. And you can see that it is he celebrates and then that was one of the flowers. But if it spots a female, then it does the reverse. So here it's accelerating. And while this male was up for a mate, this male was just looking on. Well, we had a lot of fun doing this about business. And then he stopped and went back to politics and went back to other elements. Things were very relaxed. Mike thought the four o'clock is about time to stop doing science and that he could go home and do the other things that he really liked. I mean, the university back was not stressful. It's not a few instructors said what one should do. Oh, back. The university. The long term financial planning by the government. Again, especially now the circle. We're cutting the ultimate percentage of the budget is invisible. but from the young level, you've got the people who don't need fans very cheap. And a year or so later, such as the search trucks, spent the cash that they asked people to pay and paid with their seats. I mean, like with the camera, where he made lots of other visual scientists, but Simon and that area, we're wearing the device, they've eaten better than we should be. We've eaten better than we should be. So there's a lot of time for other comments and we're all looking for something.
