P. Snow 72 00:04:25,312 --> 00:04:27,866 once said that every educated person 73 00:04:27,891 --> 00:04:30,859 should know the second law of thermodynamics. 74 00:04:31,233 --> 00:04:32,931 And that not knowing it was like 75 00:04:32,956 --> 00:04:35,734 having never read a work of Shakespeare. 76 00:04:39,375 --> 00:04:41,166 In order to discuss thermodynamics, 77 00:04:41,167 --> 00:04:43,457 we need to refer to a system. 78 00:04:43,458 --> 00:04:45,999 In this case, let's take the "humanity" system, 79 00:04:46,000 --> 00:04:48,249 with its thousands of individual particles 80 00:04:48,250 --> 00:04:50,791 moving and interacting with each other. 81 00:04:50,792 --> 00:04:53,374 And we'll focus on a few of those particles. 82 00:04:53,375 --> 00:04:55,645 For example, the Manel-particle... 83 00:04:56,333 --> 00:04:58,207 and the Elena-particle, 84 00:04:58,208 --> 00:05:00,318 who still haven't met. 85 00:05:02,750 --> 00:05:04,749 The first thing we must know 86 00:05:04,750 --> 00:05:08,150 is that all thermodynamic systems tend towards equilibrium. 87 00:05:08,958 --> 00:05:12,082 But don't be fooled by how nice this word sounds. 88 00:05:12,083 --> 00:05:13,707 It's precisely the lack 89 00:05:13,708 --> 00:05:17,041 of equilibrium that could give the Manel and Elena particles 90 00:05:17,042 --> 00:05:19,874 the chance to meet and interact, 91 00:05:19,875 --> 00:05:22,185 to build something together. 92 00:05:25,417 --> 00:05:28,916 Equilibrium in this case means the dispersion of the particles 93 00:05:28,917 --> 00:05:32,227 and the absence of activity, of heat exchange. 94 00:05:33,042 --> 00:05:37,362 Unfortunately, that's what we tend to move towards. 95 00:05:44,083 --> 00:05:48,207 You're sleeping over at my place tomorrow. I have to get up early. 96 00:05:48,208 --> 00:05:49,688 Me too. 97 00:05:50,208 --> 00:05:52,291 How was your first day of class? 98 00:05:52,292 --> 00:05:53,832 Did the boat work? 99 00:05:53,833 --> 00:05:56,533 Wonderfully, like an outboard. 100 00:05:56,708 --> 00:06:02,499 My super physicist aeronautical naval industrial nuclear engineer. 101 00:06:02,500 --> 00:06:04,582 I bet all the girls were making eyes at you. 102 00:06:04,583 --> 00:06:05,707 One of them did. 103 00:06:05,708 --> 00:06:08,957 I love how you lie to me to make me horny. 104 00:06:08,958 --> 00:06:10,957 Have you done everything yet? 105 00:06:10,958 --> 00:06:14,874 Wash the dishes, sweep the floor, air out the flat, 106 00:06:14,875 --> 00:06:17,525 lock the front door twice? 107 00:06:17,542 --> 00:06:21,124 Then the Raquel-Manuel physical system is ready to fuck. 108 00:06:21,125 --> 00:06:24,355 You still need to get your things ready for tomorrow. 109 00:06:25,125 --> 00:06:27,525 And super romantic. 110 00:06:27,917 --> 00:06:29,647 You've got it all. 111 00:06:30,875 --> 00:06:33,374 But let's go straight to heat exchange 112 00:06:33,375 --> 00:06:35,571 and the laws of thermodynamics. 113 00:06:35,596 --> 00:06:38,321 The first law of thermodynamics is very well known, 114 00:06:38,353 --> 00:06:42,403 Energy is neither created or destroyed, it simply transforms. 115 00:06:42,958 --> 00:06:44,207 What? 116 00:06:44,208 --> 00:06:45,499 It simply what? 117 00:06:45,500 --> 00:06:48,082 It's transformed, it's turned into something else. 118 00:06:48,083 --> 00:06:48,832 ONE MONTH LATER 119 00:06:48,833 --> 00:06:49,541 Into what? 120 00:06:49,542 --> 00:06:52,457 - I don't know, into affection. - Affection? 121 00:06:52,458 --> 00:06:54,374 That's what I feel for my dog. 122 00:06:54,375 --> 00:06:57,082 Not that kind, it's more special. 123 00:06:57,083 --> 00:07:01,041 But last night we fucked and you said you loved me. 124 00:07:01,042 --> 00:07:03,374 I was your proton and you were my electron. 125 00:07:03,375 --> 00:07:06,249 - You called me pickles. - Well, I mainly called you Raquel. 126 00:07:06,250 --> 00:07:08,874 What are you talking about?

It's in the books. 579 00:33:52,208 --> 00:33:55,791 You don't know because all you think about is getting laid, but the initial 580 00:33:55,792 --> 00:33:59,082 conditions within a system are what determine its evolution. 581 00:33:59,083 --> 00:34:00,082 Huh? 582 00:34:00,083 --> 00:34:01,249 What? 583 00:34:01,274 --> 00:34:05,933 It's very simple. We have a system and two parts with different temperatures. 584 00:34:05,958 --> 00:34:09,898 So the second law of thermodynamics is already set in motion. 585 00:34:10,750 --> 00:34:12,610 What was the second law? 586 00:34:14,987 --> 00:34:20,332 The second law of thermodynamics is one of the strangest laws in nature. 587 00:34:20,733 --> 00:34:23,948 It introduces a new concept which is difficult to grasp, 588 00:34:23,973 --> 00:34:25,956 but there's no way to escape it. 589 00:34:25,981 --> 00:34:29,256 This concept raises very profound questions about reality, 590 00:34:29,281 --> 00:34:34,046 and even about the meaning of time and the destiny of the universe. 591 00:34:34,263 --> 00:34:39,433 It does mean that any system evolves and degrades to some extent. 592 00:34:39,481 --> 00:34:41,041 Why aren't you answering? 593 00:34:41,066 --> 00:34:44,944 It seems to suggest why the future goes in a particular direction 594 00:34:44,969 --> 00:34:48,286 things are getting worse. I think we all notice that. 595 00:34:49,716 --> 00:34:53,001 This concept is known as entropy. 596 00:34:56,208 --> 00:34:58,478 But what is entropy? 597 00:34:58,833 --> 00:35:01,416 Get ready to understand once and for all 598 00:35:01,417 --> 00:35:04,377 something you'll never forget. How hard is it to send a message? 599 00:35:05,737 --> 00:35:10,060 We've already talked about entropy when we talked about the first law. 600 00:35:10,521 --> 00:35:15,427 Entropy measures of a degradation of good energy into a form of heat. 601 00:35:16,240 --> 00:35:20,591 In any isolated system, the entropy will always increase. 602 00:35:20,616 --> 00:35:23,745 It gets larger and larger every second. 603 00:35:24,069 --> 00:35:26,975 That's the 2nd law of thermodynamics. 604 00:35:28,723 --> 00:35:33,114 Entropy is a measure of energy that is lost and cannot be recovered. 605 00:35:36,330 --> 00:35:39,908 Even though heat is one of the most common form of energy transfer 606 00:35:39,933 --> 00:35:42,066 we are used to in our daily life, 607 00:35:42,091 --> 00:35:44,160 it's very inefficient. 608 00:35:47,068 --> 00:35:49,660 We cannot create anything from heat. 609 00:35:49,958 --> 00:35:53,185 So, heat and entropy is a bad thing. 610 00:35:54,400 --> 00:35:58,153 Heat is the most random and low quality form of energy. 611 00:35:58,178 --> 00:36:00,459 A text message is too much? 612 00:36:02,749 --> 00:36:06,814 You need a huge amount of heat to obtain minimum performance. 613 00:36:06,839 --> 00:36:10,477 For example, let's compare it to the breaking of a nucleus in an atom. 614 00:36:10,502 --> 00:36:12,298 There's someone else. 615 00:36:19,920 --> 00:36:24,084 Heat is the by-product of an engine's operation. 616 00:36:24,543 --> 00:36:30,666 That's why entropy is a measure of useless, wasted energy. 617 00:36:31,442 --> 00:36:33,392 But there's still more. 618 00:36:33,417 --> 00:36:35,291 There's another way to look at entropy 619 00:36:35,292 --> 00:36:39,112 and it's even more troubling, even more devastating. 620 00:36:39,875 --> 00:36:42,291 I was up all night gluing it back together. 621 00:36:42,292 --> 00:36:44,192 You didn't have to. 622 00:36:45,500 --> 00:36:47,650 It doesn't look so bad. 623 00:36:47,875 --> 00:36:50,624 - After all you went through to... - It's okay. 624 00:36:50,625 --> 00:36:53,565 It has even more personality now. 625 00:36:55,708 --> 00:36:58,108 It wasn't such a pretty sculpture. 626 00:36:59,625 --> 00:37:05,642 I can't see you this week, Manel, I'll be too busy with the short film. 627 00:37:05,667 --> 00:37:09,124 You can visit me on the set, but I can't spend any time with you. 628 00:37:09,125 --> 00:37:11,166 You're leaving already? You just got here. 629 00:37:11,167 --> 00:37:13,687 I'm sorry, I can't stay. I have a rehearsal. 630 00:37:13,917 --> 00:37:16,082 - Is everything okay? - I don't know. 631 00:37:16,083 --> 00:37:17,983 Is everything okay? 632 00:37:18,542 --> 00:37:20,874 You didn't answer my messages yesterday. 633 00:37:20,875 --> 00:37:23,832 I didn't. Wow. I'm sorry I'm so busy. 634 00:37:23,833 --> 00:37:25,874 - Really. - Is that all? 635 00:37:25,875 --> 00:37:28,100 That's all. Don't freak out. 636 00:37:28,125 --> 00:37:32,315 You might be going a little fast for me. But everything's fine, okay? 637 00:37:32,500 --> 00:37:37,030 See you on Sunday. Come up with some law of physics to explain to me. 638 00:37:37,458 --> 00:37:38,791 Wish me luck. 639 00:37:38,792 --> 00:37:40,362 Good luck. 640 00:37:43,965 --> 00:37:45,786 Heat, on the microscopic level, 641 00:37:45,818 --> 00:37:48,689 is the movement of the particles that form the system. 642 00:37:48,714 --> 00:37:52,834 The fact that you have heat means that the particles will get agitated. 643 00:37:53,337 --> 00:37:56,897 The hotter the system, the faster particles move, 644 00:37:56,922 --> 00:37:59,066 and the cooler the system, 645 00:37:59,091 --> 00:38:02,305 the more quiet and more ordered are the particles. 646 00:38:02,337 --> 00:38:07,341 Therefore, entropy can also be seen as a measure of the disorder of the system. 647 00:38:08,350 --> 00:38:11,656 The higher the entropy, the more the disorder 648 00:38:11,681 --> 00:38:16,523 and less likely it will be to find a particle in its original position. 649 00:38:17,833 --> 00:38:21,249 Hi, excuse me. I'm here to see Elena, I'm Manel. 650 00:38:21,250 --> 00:38:24,041 Manel? Manel who?

Entropy goes up. 794 00:47:20,898 --> 00:47:23,308 Irreversible processes happen. 795 00:47:31,536 --> 00:47:35,413 The 2nd law of thermodynamics forces us to think deeper 796 00:47:35,438 --> 00:47:39,413 on the very nature of fundamental processes in systems. 797 00:47:41,388 --> 00:47:45,875 It is in fact impossible to go back to the exact same initial conditions. 798 00:47:52,681 --> 00:47:55,699 There are two things we know that have only one direction, 799 00:47:55,724 --> 00:47:59,511 and that's the increase of entropy and the arrow of time. 800 00:47:59,660 --> 00:48:03,367 And perhaps even entropy can be thought of as... being responsible 801 00:48:03,392 --> 00:48:07,087 for the only one direction of time that we experience. 802 00:48:10,516 --> 00:48:12,662 The 2nd law of thermodynamics is very important 803 00:48:12,687 --> 00:48:14,527 because it puts a limit. 804 00:48:15,919 --> 00:48:17,733 If it didn't exist, then yes, 805 00:48:17,758 --> 00:48:21,162 we would be able to go back to the initial energy. 806 00:48:25,625 --> 00:48:29,275 No, I'm okay. It's fine, we'll hook up another time. 807 00:48:29,542 --> 00:48:31,957 Yeah, don't worry, we'll talk later. 808 00:48:31,958 --> 00:48:34,478 I'm fine.

What is it's ultimate destination? 1432 01:27:47,182 --> 01:27:50,012 It was thought that if the universe had enough mass, 1433 01:27:50,037 --> 01:27:52,423 the whole expansion could be reverted. 1434 01:27:52,448 --> 01:27:54,795 And the universe will end up collapsing again 1435 01:27:54,820 --> 01:27:57,782 into what is known as the Big Crunch. 1436 01:27:59,542 --> 01:28:02,249 This beautiful theory foresaw that everyone, 1437 01:28:02,250 --> 01:28:04,999 even Elena and me, would be brought back together 1438 01:28:05,000 --> 01:28:07,360 in a warm and eternal embrace. 1439 01:28:09,903 --> 01:28:14,151 But the fateful news arrived barely 2 decades ago. 1440 01:28:14,176 --> 01:28:20,713 The universe is not just expanding, that expansion is actually accelerating. 1441 01:28:21,162 --> 01:28:23,896 We are moving away faster and faster. 1442 01:28:24,295 --> 01:28:28,849 So, the final destiny of the universe might not be the thermal death, 1443 01:28:28,874 --> 01:28:33,392 but a kind of tear in the space-time of the universe, called the Big Rip. 1444 01:28:33,417 --> 01:28:35,497 The Big Rip. 1445 01:28:35,522 --> 01:28:39,094 At this point that ending sounds about right to me. 1446 01:28:42,083 --> 01:28:45,971 The force causing this acceleration has been called dark energy, 1447 01:28:45,996 --> 01:28:48,700 basically because we don't know what it is. 1448 01:28:48,725 --> 01:28:50,608 Because it's a mystery. 1449 01:28:52,158 --> 01:28:55,218 Maybe I can shed some light on this point. 1450 01:28:56,708 --> 01:28:58,919 This force that distances us 1451 01:28:58,944 --> 01:29:01,318 is the same force that stopped the Manel-body 1452 01:29:01,343 --> 01:29:03,600 from truly giving himself to the Elena-body 1453 01:29:03,625 --> 01:29:05,624 and seeing things as they really were. 1454 01:29:05,625 --> 01:29:08,332 It's the same force that destroys true love 1455 01:29:08,333 --> 01:29:11,374 and strengthens mediocre relationships, makes us selfish, 1456 01:29:11,375 --> 01:29:13,815 petty and suspicious. 1457 01:29:14,208 --> 01:29:15,608 Fear. 1458 01:29:17,250 --> 01:29:18,730 Fear. 1459 01:29:19,542 --> 01:29:22,499 Fear is what made me hide behind those laws, 1460 01:29:22,500 --> 01:29:23,457 I see it clearly now. 1461 01:29:23,458 --> 01:29:26,978 So I wouldn't have to face my own mistakes, my failure. 1462 01:29:27,458 --> 01:29:28,999 Elena was right, 1463 01:29:29,000 --> 01:29:32,291 thinking they can be applied to love is insane. 1464 01:29:32,292 --> 01:29:35,207 Though the coincidences are pretty amazing, aren't they? 1465 01:29:35,208 --> 01:29:38,568 What do you think?
