0:00:14.175,0:00:16.315 We have incredible potential. 0:00:17.176,0:00:19.186 But how much do we really know 0:00:19.186,0:00:24.025 about what are the most effective ways[br]for us to extract this potential? 0:00:24.025,0:00:26.746 To overcome obstacles?[br]To reach our goals? 0:00:26.746,0:00:29.656 To change as we need[br]to change along the way? 0:00:29.656,0:00:31.617 To learn? To evolve? 0:00:31.996,0:00:34.967 I'm a professor of computer science, 0:00:34.967,0:00:38.188 and my area of research[br]is quantum computation. 0:00:39.229,0:00:41.599 No, it's not computers[br]that don't exist yet. 0:00:41.599,0:00:45.350 But imagine computers[br]that will take one second 0:00:45.350,0:00:47.720 to solve certain computational tasks 0:00:47.720,0:00:50.360 that the fastest[br]supercomputer in the world 0:00:50.360,0:00:53.010 will take zillions of years to solve. 0:00:53.420,0:00:55.110 Thousands of researchers 0:00:55.110,0:00:58.230 all over the world are now trying[br]to build those computers, 0:00:58.230,0:01:01.916 and also trying to understand[br]what you will be able to do with them 0:01:01.916,0:01:04.512 if and when we manage to build them. 0:01:05.622,0:01:08.822 I deal with difficult challenges[br]on a daily basis. 0:01:08.822,0:01:12.838 I'm really interested[br]in trying to find ways 0:01:12.838,0:01:16.972 to overcome obstacles, and learning,[br]which are more effective. 0:01:18.942,0:01:22.642 Now, during my career[br]I've had ups and downs. 0:01:23.712,0:01:26.961 I was fortunate enough to have[br]a very, very successful PhD. 0:01:26.961,0:01:31.204 But immediately after my PhD,[br]I went into this numb period 0:01:31.204,0:01:34.133 in which nothing seemed to actually work, 0:01:35.011,0:01:37.722 even though I was putting[br]a lot of effort into it. 0:01:38.482,0:01:41.142 My friend came to me and told me 0:01:41.592,0:01:47.115 "Dorit, you've painted[br]a very beautiful picture in your PhD. 0:01:47.115,0:01:48.995 But you're putting in too much effort. 0:01:49.685,0:01:54.966 Maybe it's time to let go, sign it up,[br]and move on to the next picture." 0:01:55.285,0:01:58.480 And he was right; I was clinging[br]to it with all my might. 0:01:58.480,0:02:00.604 I was applying a lot of force. 0:02:00.604,0:02:02.744 That's one way of applying force. 0:02:03.084,0:02:06.206 But we do that all the time[br]in many, many different contexts 0:02:06.206,0:02:08.552 and many variations. 0:02:08.982,0:02:11.376 Imagine yourself opening a drawer. 0:02:11.886,0:02:13.256 You try to open it. 0:02:13.256,0:02:14.506 It doesn't open. 0:02:14.816,0:02:15.640 It's stuck. 0:02:15.640,0:02:16.856 What do you do? 0:02:16.856,0:02:18.147 You try harder. 0:02:18.147,0:02:21.177 And if it doesn't work,[br]you try even harder. 0:02:21.177,0:02:22.667 It might even break. 0:02:23.597,0:02:25.885 You tell yourself[br]you have to finish an exercise, 0:02:25.885,0:02:28.027 so you force yourself to do it. 0:02:28.027,0:02:32.656 You want to go on a diet,[br]you force yourself to do it. 0:02:32.826,0:02:34.506 You need to finish this book 0:02:34.506,0:02:37.446 that's been lying[br]near your bed for a month, 0:02:37.446,0:02:39.366 you force yourself to do it. 0:02:39.647,0:02:44.468 I'm not saying that as a criticism,[br]it's just an observation. 0:02:44.468,0:02:47.929 We see this all around us,[br]it's something very natural for us to do, 0:02:47.929,0:02:50.658 and that's what we've probably[br]been told to do 0:02:50.658,0:02:53.119 many times when we were very young. 0:02:54.057,0:02:58.537 But we lose a lot[br]from this forceful approach. 0:02:58.537,0:03:00.418 We lose a lot in quality. 0:03:00.908,0:03:03.958 We lose our sensitivity, our creativity. 0:03:03.958,0:03:08.138 Imagine a kid who hates mathematics 0:03:08.138,0:03:11.737 and is forced to do[br]a mathematical exercise. 0:03:11.737,0:03:13.883 It's not a very pretty[br]sight to see, right? 0:03:13.883,0:03:16.368 It's not inspiring. 0:03:16.368,0:03:19.558 It's as if some other part[br]of his brain has taken over him, 0:03:19.558,0:03:23.788 and it's doing the job[br]but it's doing it very, very poorly. 0:03:24.492,0:03:30.240 But there's a different kind[br]of thinking and learning 0:03:30.460,0:03:34.369 which is much more connected to ourselves,[br]and much more attentive, 0:03:35.949,0:03:37.639 and of a much higher quality - 0:03:37.969,0:03:41.157 something which is much more connected,[br]much more attentive; 0:03:42.387,0:03:44.948 it's more sensitive and more creative. 0:03:44.948,0:03:50.609 I want to give you an experience[br]of such a learning and thinking process 0:03:50.609,0:03:52.139 which is not forced. 0:03:59.969,0:04:03.429 I'm holding a glass of water[br]here in front of you, 0:04:03.429,0:04:06.790 and I'm going to rotate[br]this glass around itself 0:04:06.790,0:04:11.305 without spilling the water, and without[br]detaching my hand from the glass. 0:04:11.305,0:04:12.871 Here, watch me do it. 0:04:16.391,0:04:18.101 Good, worked the first time. 0:04:19.894,0:04:21.480 Now I have a question for you. 0:04:22.280,0:04:25.071 How many times did the glass[br]rotate around itself? 0:04:25.511,0:04:27.341 I'll let you watch me do it again.[br] 0:04:27.341,0:04:28.571 Watch carefully. 0:04:31.891,0:04:32.995 Okay. 0:04:37.321,0:04:39.600 It doesn't matter;[br]the answer doesn't matter. 0:04:39.600,0:04:45.372 The point is that my question - if you're[br]curious and intrigued by the movement - 0:04:45.372,0:04:49.852 my question triggered some spontaneous[br]thinking process inside you 0:04:49.852,0:04:52.622 that was unforced. 0:04:52.622,0:04:55.181 It was something[br]connected to your curiosity 0:04:55.181,0:04:57.632 and something that came from within. 0:04:58.341,0:05:00.662 The answer, by the way, is two. 0:05:02.192,0:05:06.152 I'm looking for ways to maintain[br]those kind of qualities - 0:05:06.152,0:05:10.822 sensitivity, creativity -[br]those connections within us, 0:05:10.822,0:05:13.802 not only with such simple exercises, 0:05:13.802,0:05:18.443 but also in front of the hardest obstacles[br]that we want to overcome. 0:05:18.873,0:05:21.773 For that matter, let me[br]move on to my other passion. 0:05:22.193,0:05:24.892 I've done body-mind methods for years. 0:05:24.892,0:05:29.422 I practice tai chi,[br]king fu, yoga, Feldenkrais. 0:05:29.782,0:05:34.083 One day, my kung fu teacher came to me -[br]it was while I was doing this kick - 0:05:34.953,0:05:36.073 and he told me, 0:05:36.073,0:05:40.304 "Dorit, pay attention to how[br]you return your leg back from the kick." 0:05:41.424,0:05:46.045 Now, actually, I never even knew[br]I'm returning my leg back from the kick. 0:05:46.045,0:05:49.830 It always seemed to me like my kick[br]ended with my leg up in the air, 0:05:49.830,0:05:51.644 and the rest didn't exist. 0:05:52.169,0:05:57.567 And then it occurred to me,[br]it's exactly how I operate in life. 0:05:57.567,0:05:59.465 I throw myself into challenges, 0:05:59.465,0:06:02.635 and then I don't care about[br]how I come back from them. 0:06:03.656,0:06:06.896 What we do with our physical body,[br]our physical patterns, 0:06:06.896,0:06:12.327 are actually intimately connected[br]to how we interact with life in general. 0:06:13.110,0:06:18.986 I want to give you four principles[br]I've extracted from body-mind methods. 0:06:19.376,0:06:23.896 And those principles, I think,[br]are very useful for overcoming obstacles 0:06:23.896,0:06:26.446 and learning in general 0:06:27.237,0:06:33.027 while maintaining your sensitivity,[br]and creativity, and capabilities, 0:06:33.027,0:06:35.518 even in front of very difficult obstacles. 0:06:35.518,0:06:39.896 Now, those principles don't only apply[br]to physical movement, 0:06:39.896,0:06:44.164 I think they apply to overcoming[br]challenges in general. 0:06:44.417,0:06:47.576 In fact, they also apply[br]to my scientific research 0:06:47.576,0:06:49.437 and for learning mathematics. 0:06:51.220,0:06:55.087 I'm going to give you an example[br]coming from a Feldenkrais lesson 0:06:55.087,0:06:57.860 and extract the principles[br]from it one by one. 0:06:58.776,0:07:01.076 I'm just taking Feldenkrais as an example; 0:07:01.846,0:07:04.948 I could have taken other[br]body-mind methods as well, 0:07:05.428,0:07:07.848 but this is a particularly[br]illuminating example. 0:07:09.226,0:07:12.544 You see here my Feldenkrais[br]teacher, Eilat Almagor, 0:07:12.940,0:07:16.110 and she's giving a lesson[br]to a child called Yuval. 0:07:17.542,0:07:23.691 Yuval came to the lesson with some kind[br]of asymmetry in the way he's sitting. 0:07:24.098,0:07:27.903 He finds it difficult to lean[br]on his left sitting bone. 0:07:28.253,0:07:30.353 He leans on his right sitting bone. 0:07:30.833,0:07:35.822 That means that he can't take his right[br]leg to the right, like that, while sitting 0:07:35.822,0:07:38.154 because he can't lift[br]his right sitting bone. 0:07:38.782,0:07:40.744 By the end of the lesson, however, 0:07:40.744,0:07:45.623 Yuval actually brings his right leg[br]to the right on his own. 0:07:45.623,0:07:49.323 I want to give you the key steps[br]of what's going on in the lesson, 0:07:49.323,0:07:52.345 and walk you through those key steps, 0:07:52.345,0:07:55.233 and extract the principles one by one. 0:07:56.265,0:07:57.985 (Video) Dorit Aharonov: Eilat starts 0:07:57.985,0:08:00.335 by working with Yuval's[br]right sitting bone. 0:08:00.335,0:08:02.315 Now this might seem counterintuitive 0:08:02.315,0:08:06.274 because Yuval already knows[br]how to lean on his right sitting bone. 0:08:07.664,0:08:09.836 (On stage) DA: You might think[br]that this means 0:08:09.836,0:08:13.416 that he will actually move[br]further to the right. 0:08:13.416,0:08:17.686 And indeed, a little bit later,[br]he does move further to the right. 0:08:18.196,0:08:19.537 First principle: 0:08:19.537,0:08:24.548 Start within your comfort zone,[br]and make it even more comfortable. 0:08:24.933,0:08:26.497 The next thing that Eilat does,[br] 0:08:26.497,0:08:30.317 is now that Yuval is very comfortable[br]with where he is, 0:08:30.317,0:08:36.429 she inserts one little new ingredient[br]into his scenario. 0:08:36.429,0:08:41.412 She just lets him feel that he can[br]be supported in his left sitting bone. 0:08:42.238,0:08:44.649 But this is done within his comfort zone. 0:08:45.859,0:08:49.219 She just picks one[br]little thing to add to it. 0:08:49.700,0:08:54.270 Pick a challenge which[br]is interesting, within your reach, 0:08:54.270,0:08:56.480 not too easy, not too hard. 0:08:57.720,0:09:00.809 The next thing that Eilat does[br]might look a bit weird. 0:09:00.809,0:09:04.222 She lifts Yuval up in the air[br]and lets him fall, 0:09:04.222,0:09:06.321 and she does it from various directions. 0:09:06.830,0:09:08.161 Now what she actually does, 0:09:08.161,0:09:12.161 is she takes him away[br]from what he has just learned, 0:09:12.161,0:09:13.941 to lean on both his sitting bones, 0:09:13.941,0:09:18.002 and lets him know that he can return back[br]to what he just learned 0:09:18.002,0:09:19.589 from different directions. 0:09:19.899,0:09:21.320 Third principle: 0:09:21.320,0:09:23.581 Move away from your desired goal, 0:09:23.581,0:09:26.131 and come back to it[br]from different directions. 0:09:26.891,0:09:31.081 Now, you might have noticed[br]that during the whole time, 0:09:31.081,0:09:36.128 Yuval continues to play,[br]and do various things, and move. 0:09:36.388,0:09:39.171 It's all happening[br]within his comfort zone. 0:09:39.561,0:09:42.847 He integrates everything[br]that he's learning into his own life. 0:09:42.847,0:09:44.363 Fourth and last principle: 0:09:44.683,0:09:47.523 Play with it, connect it[br]to everything you know, 0:09:47.523,0:09:48.715 make it your own. 0:09:49.043,0:09:54.172 A little bit later, Yuval takes his leg[br]to the right on his own. 0:09:54.432,0:09:57.132 The movement has already become his own. 0:09:57.643,0:09:59.843 I want to repeat those four principles. 0:10:00.703,0:10:04.453 Start within your comfort zone[br]and make it even more comfortable. 0:10:05.973,0:10:07.133 Second principle: 0:10:07.773,0:10:09.772 Not too easy, not too hard: 0:10:09.772,0:10:12.722 Pick an interesting challenge[br]within your reach. 0:10:14.193,0:10:15.289 Third principle: 0:10:15.289,0:10:20.079 Move away from your desired goal,[br]and come back to it from different angles. 0:10:20.649,0:10:22.044 Fourth principle: 0:10:22.044,0:10:24.734 Play with it, connect it,[br]make it your own. 0:10:25.888,0:10:31.174 Okay, now these principles,[br]they're effective, as you've seen, 0:10:31.174,0:10:33.002 in the context of movement. 0:10:33.002,0:10:36.304 But I find them to be very, very effective[br]also in other contexts. 0:10:36.304,0:10:38.874 And in particular,[br]in my scientific research, 0:10:38.874,0:10:41.144 and in the context[br]of mathematics in general. 0:10:41.484,0:10:43.159 Now, I want to give you an example 0:10:43.159,0:10:46.873 of how to use those principles[br]in the context of mathematics, 0:10:47.483,0:10:49.173 in the context of a small riddle. 0:10:50.004,0:10:52.314 Once upon a time, there was a queen. 0:10:53.638,0:10:57.704 The queen ruled her island because[br]she was the only one on the island 0:10:57.704,0:10:59.914 who knew how to do the following trick. 0:10:59.914,0:11:03.343 She had two cubes;[br]each cube had six faces, 0:11:03.343,0:11:05.723 and on each face,[br]there is a digit written. 0:11:06.154,0:11:09.643 Now, what she knew[br]how to do with those cubes 0:11:09.643,0:11:15.444 is she knew how to represent[br]all dates in the month with those cubes. 0:11:15.928,0:11:20.674 Now, this is a bit confusing because[br]there are only six faces on each cube, 0:11:20.674,0:11:22.933 and there are ten digits to write on them, 0:11:22.933,0:11:24.603 so how did she do that? 0:11:25.183,0:11:30.458 I want to solve this riddle with you[br]using the principles that I've just shown, 0:11:30.458,0:11:34.810 and I'll have this place here[br]at the top corner of the screen 0:11:34.810,0:11:37.973 where the principle[br]that we're now using will be written. 0:11:39.042,0:11:40.924 So that you can keep track of it. 0:11:41.634,0:11:43.345 We start with what we need to do. 0:11:44.549,0:11:49.136 We need to write six digits on each cube[br]so I make space for those digits, 0:11:49.576,0:11:50.796 six for each cube. 0:11:51.221,0:11:54.715 Now let's start[br]with a very, very small step. 0:11:54.715,0:11:58.025 Let's just write the first date - 01. 0:11:58.556,0:12:02.336 So we need a 0 on the first cube,[br]and we need a 1 on the second cube 0:12:02.336,0:12:03.556 so we do that. 0:12:03.916,0:12:07.736 Well that was easy enough,[br]so let's continue this way. 0:12:08.376,0:12:13.355 We can also write 02, 03, 04, 05. 0:12:15.115,0:12:19.485 Okay, but we can't continue like that[br]for all dates that start with 0, 0:12:19.485,0:12:22.126 there's just not enough room[br]in the right cube. 0:12:22.396,0:12:27.465 So now we see that we can[br]identify a simple goal 0:12:27.465,0:12:30.608 that is still something interesting[br]that we don't know how to do. 0:12:31.330,0:12:36.883 Let's try to represent[br]all the dates that start with 0 - 0:12:37.277,0:12:39.316 the left-most column. 0:12:40.994,0:12:45.258 We see that we can't just do that[br]with just one 0 on one cube, 0:12:45.258,0:12:48.718 but if we add one 0 on the right cube, 0:12:48.718,0:12:52.458 then you can combine it[br]with all the digits 0:12:52.458,0:12:54.989 by putting all the other digits[br]on the left cube. 0:12:54.989,0:12:57.338 So now we are done with the left column. 0:12:58.189,0:13:03.129 But we can take this idea of having[br]0 on both cubes to the next column. 0:13:04.528,0:13:06.346 We can solve now for the next column 0:13:06.346,0:13:10.147 which consists of all numbers[br]that start with 1, 0:13:10.147,0:13:12.519 by just putting 1 on both cubes. 0:13:13.449,0:13:17.019 We can do that because we have more room,[br]we add a 1 to the left cube, 0:13:17.019,0:13:18.529 and now we have 1 on both cubes 0:13:18.529,0:13:21.338 and we can do all combinations[br]with all the other digits. 0:13:21.738,0:13:24.152 So that's fine for the second column. 0:13:24.518,0:13:26.489 Now we want to do the third column. 0:13:27.118,0:13:29.940 So if we can put 2 on both cubes,[br]that would be great, 0:13:29.940,0:13:31.441 but we don't have more room. 0:13:31.841,0:13:33.140 So now what do we do? 0:13:33.420,0:13:38.291 Well, we use the next principle,[br]and we make a deliberate mistake. 0:13:38.291,0:13:43.052 We move away from our target and we add 2,[br]even though we don't have room for that. 0:13:43.550,0:13:45.260 Maybe we can correct for it later. 0:13:45.831,0:13:49.391 Okay, so now we have 2 on the left cube, 0:13:49.391,0:13:52.791 and you can check that[br]you can now write all the 20s, 0:13:53.161,0:13:56.120 and you can also see[br]that you can write 30 and 31. 0:13:56.910,0:14:00.491 Great, but now we have[br]seven digits on the left cube. 0:14:00.491,0:14:02.730 So how do we correct for that? 0:14:05.520,0:14:09.032 I need all the digits on the left cube,[br]so what do I do? 0:14:09.782,0:14:13.652 Now I want to use the fourth principle:[br]I want to play with it. 0:14:15.152,0:14:17.466 So let's get serious with playing. 0:14:19.284,0:14:23.245 I brought here with me[br]two colorful cubes from that island, 0:14:23.625,0:14:25.898 and I want to play with them. 0:14:26.327,0:14:30.865 I'm going to play with them,[br]and I can write here - 0:14:31.135,0:14:32.771 they're going to break, actually - 0:14:32.771,0:14:35.965 okay, I have a 2 here;[br]I can write 20-something. 0:14:36.306,0:14:37.485 Let's see. 0:14:37.835,0:14:39.600 I can write 21. 0:14:39.885,0:14:41.416 I can write 27. 0:14:41.781,0:14:44.276 I can write 26. 0:14:45.146,0:14:46.286 29! 0:14:46.286,0:14:48.545 Right, I can also write 29. 0:14:48.784,0:14:51.055 Aha, you've got it already. 0:14:51.265,0:14:55.095 I don't need the 6 and 9. 0:14:56.670,0:14:58.906 And that's the solution. 0:14:59.809,0:15:02.095 Now, you might be thinking, 0:15:02.095,0:15:06.285 "Hmm, is this all it takes[br]to be a quantum computer scientist? 0:15:06.598,0:15:08.976 Just rotate colorful cubes 0:15:08.976,0:15:12.765 and lift your right and left[br]sitting bone once in a while, 0:15:12.765,0:15:15.696 and follow your butt once in a while?" 0:15:15.696,0:15:17.966 Well, the answer is... 0:15:18.386,0:15:19.836 honestly, yes. 0:15:22.506,0:15:25.046 Now seriously, I strongly believe 0:15:25.046,0:15:30.855 that all scientific discoveries,[br]great or small, 0:15:30.855,0:15:34.286 can be boiled down[br]to a very small, little step 0:15:34.286,0:15:37.715 of maybe a twist or a rotation[br]around what you thought before, 0:15:37.715,0:15:40.935 or looking at things[br]from a different angle, 0:15:40.935,0:15:43.515 or making an unexpected connection. 0:15:44.065,0:15:48.255 And playing with it[br]will reveal those things. 0:15:48.746,0:15:53.387 And this is exactly what we're doing now[br]in the area of quantum computation. 0:15:53.387,0:15:57.927 In this area, we are actually at the state[br]of Yuval in the beginning of the lesson. 0:15:57.927,0:16:00.499 We don't know yet[br]how to build those computers. 0:16:00.499,0:16:04.057 And we don't know yet[br]what we will be able to do with them, 0:16:04.057,0:16:06.267 if and when they're built. 0:16:06.267,0:16:10.948 But what we're doing is,[br]we start within our comfort zone, 0:16:10.948,0:16:14.299 we look around to see[br]where we can expand it, 0:16:14.299,0:16:16.083 where we can find challenges 0:16:16.083,0:16:18.382 within our reach[br]that are still interesting, 0:16:18.382,0:16:20.628 and once we find them[br]and manage to get them, 0:16:20.628,0:16:22.450 we try to understand it further, 0:16:22.450,0:16:25.491 we try to go back and forth[br]in order for it to be reliable. 0:16:25.491,0:16:27.751 We try to fall on it[br]from different directions, 0:16:27.751,0:16:29.960 and we keep continuing to play. 0:16:30.230,0:16:34.160 And that is something[br]that has already been very useful, 0:16:34.160,0:16:36.780 even without reaching[br]our goals, our big goals, 0:16:36.780,0:16:39.060 we already found very,[br]very interesting things 0:16:39.060,0:16:43.042 and many new areas have been opened,[br]and many new connections, 0:16:43.042,0:16:44.513 just by this approach. 0:16:44.783,0:16:50.436 Do you have a goal in your life[br]that you haven't managed to move 0:16:50.686,0:16:53.913 or make progress on for a long time? 0:16:54.128,0:16:56.404 I invite you to check - maybe... 0:16:56.594,0:16:57.903 maybe... 0:16:57.903,0:17:00.734 you're putting just too much energy 0:17:00.734,0:17:04.284 in a direction that you expect[br]things to move. 0:17:04.544,0:17:10.476 And maybe by reducing the amount of force[br]and letting it move in other directions, 0:17:10.476,0:17:12.654 you might find yourself[br]in a different place 0:17:12.654,0:17:15.224 which could be very close[br]to where you are now, 0:17:15.224,0:17:18.666 but it will be a different place[br]from which things will look different. 0:17:19.626,0:17:25.496 I find that resisting the temptation[br]of using the forceful approach 0:17:25.496,0:17:27.975 is a lifelong process of awareness, 0:17:27.975,0:17:29.595 but I think it's worthwhile 0:17:29.595,0:17:33.686 because you gain your sensitivity,[br]your creativity, your liveliness, 0:17:33.686,0:17:35.607 in front of difficult obstacles. 0:17:35.607,0:17:38.037 And even if you don't reach[br]what you wanted, 0:17:38.037,0:17:41.887 well, you reach other places[br]which could be as interesting. 0:17:42.567,0:17:43.946 Thank you for listening. 0:17:43.946,0:17:46.475 (Applause) 0:17:46.475,0:17:47.627 (Whistles) 0:17:47.627,0:17:49.237 (Cheers)
