  95. 23
  96. 00:02:35,447 --> 00:02:38,992
  97. We never really saw our world
  98.  
  99. 24
  100. 00:02:39,117 --> 00:02:41,703
  101. until they showed it to us.
  102.  
  103. 25
  104. 00:02:41,828 --> 00:02:44,164
  105.  
  106.  
  107. 26
  108. 00:02:46,416 --> 00:02:48,585
  109. Through the power of imagination,
  110.  
  111. 27
  112. 00:02:48,710 --> 00:02:50,962
  113. they astonish us.
  114.  
  115. 28
  116. 00:02:52,839 --> 00:02:56,510
  117. They're called engineers.
  118.  
  119. 29
  120. 00:03:02,057 --> 00:03:04,935
  121. With each life-changing creation,
  122.  
  123. 30
  124. 00:03:05,060 --> 00:03:07,354
  125. like the International Space Station,
  126.  
  127. 31
  128. 00:03:07,479 --> 00:03:11,650
  129. engineers enhance
  130. the human experience.
  131.  
  132. 32
  133. 00:03:11,775 --> 00:03:14,611
  134. They build civilizations.
  135.  
  136. 33
  137. 00:03:19,366 --> 00:03:21,743
  138.  
  139.  
  140. 34
  141. 00:03:26,748 --> 00:03:30,293
  142. Every bridge,
  143. every building grows
  144.  
  145. 35
  146. 00:03:30,419 --> 00:03:33,922
  147. from an engineer's imagination.
  148.  
  149. 36
  150. 00:03:42,806 --> 00:03:46,935
  151. There are now seven billion of us.
  152.  
  153. 37
  154. 00:03:47,060 --> 00:03:49,187
  155. And by 2045,
  156.  
  157. 38
  158. 00:03:49,312 --> 00:03:52,065
  159. there will be two billion more.
  160.  
  161. 39
  162. 00:03:52,190 --> 00:03:54,359
  163.  
  164.  
  165. 40
  166. 00:03:54,484 --> 00:03:56,820
  167. Where will we all live?
  168.  
  169. 41
  170. 00:03:58,238 --> 00:04:01,450
  171. Will we have enough clean energy?
  172.  
  173. 42
  174. 00:04:03,910 --> 00:04:06,288
  175. The boldest solutions
  176.  
  177. 43
  178. 00:04:06,413 --> 00:04:08,707
  179. start with the biggest dreams.
  180.  
  181. 44
  182. 00:04:11,668 --> 00:04:14,045
  183.  
  184.  
  185. 45
  186. 00:04:22,262 --> 00:04:24,639
  187.  
  188.  
  189. 46
  190. 00:04:34,608 --> 00:04:36,985
  191.  
  192.  
  193. 47
  194. 00:04:38,737 --> 00:04:41,072
  195.  
  196.  
  197. 48
  198. 00:04:52,751 --> 00:04:55,128
  199.  
  200.  
  201. 49
  202. 00:05:09,392 --> 00:05:11,978
  203.  
  204.  
  205. 50
  206. 00:05:12,103 --> 00:05:13,480
  207. Menzer Pehlivan
  208.  
  209. 51
  210. 00:05:13,605 --> 00:05:15,982
  211. grew up in Turkey.
  212.  
  213. 52
  214. 00:05:17,984 --> 00:05:20,320
  215. I was a girly girl.
  216.  
  217. 53
  218. 00:05:21,696 --> 00:05:24,533
  219. I was a lead in schools plays.
  220.  
  221. 54
  222. 00:05:24,658 --> 00:05:26,910
  223. I actually wanted to be an actress.
  224.  
  225. 55
  226. 00:05:29,788 --> 00:05:34,597
  227. Until I was 13,
  228. when everything changed.
  229.  
  230. 56
  231. 00:05:34,598 --> 00:05:36,100
  232.  
  233.  
  234. 57
  235. 00:05:36,225 --> 00:05:38,018
  236.  
  237.  
  238. 58
  239. 00:05:38,144 --> 00:05:40,271
  240.  
  241.  
  242. 59
  243. 00:05:40,396 --> 00:05:43,107
  244. We lived in a high-rise building.
  245.  
  246. 60
  247. 00:05:43,232 --> 00:05:45,985
  248. I remember my mother
  249. waking me up,
  250.  
  251. 61
  252. 00:05:46,110 --> 00:05:49,822
  253. terrified that the building
  254. would come down.
  255.  
  256. 62
  257. 00:05:49,947 --> 00:05:52,324
  258.  
  259.  
  260. 63
  261. 00:05:52,450 --> 00:05:56,829
  262. I remember watching
  263. the people suffering.
  264.  
  265. 64
  266. 00:05:59,623 --> 00:06:03,294
  267. From that moment on,
  268. I knew what I wanted to do.
  269.  
  270. 65
  271. 00:06:06,881 --> 00:06:10,176
  272. Today, I'm a professional
  273. engineer in Seattle,
  274.  
  275. 66
  276. 00:06:10,301 --> 00:06:13,929
  277. hoping to make structures
  278. safer during earthquakes.
  279.  
  280. 67
  281. 00:06:18,642 --> 00:06:20,144
  282. I love my job.
  283.  
  284. 68
  285. 00:06:20,269 --> 00:06:22,771
  286. And I want kids to be
  287. excited about engineering
  288.  
  289. 69
  290. 00:06:22,897 --> 00:06:24,607
  291. as much as I am.
  292.  
  293. 70
  294. 00:06:24,732 --> 00:06:26,066
  295. So, are you ready for the earthquake?
  296.  
  297. 71
  298. 00:06:26,192 --> 00:06:27,443
  299. - Yeah!
  300. - Yeah?
  301.  
  302. 72
  303. 00:06:27,568 --> 00:06:29,987
  304. Three, two, one.
  305.  
  306. 73
  307. 00:06:30,112 --> 00:06:32,490
  308. Let's start slow.
  309.  
  310. 74
  311. 00:06:34,200 --> 00:06:36,160
  312. - Which one is...
  313. - Go faster.
  314.  
  315. 75
  316. 00:06:36,285 --> 00:06:37,828
  317.  
  318.  
  319. 76
  320. 00:06:39,330 --> 00:06:40,706
  321. To design safer buildings,
  322.  
  323. 77
  324. 00:06:40,831 --> 00:06:44,293
  325. we study how soil moves
  326. during an earthquake.
  327.  
  328. 78
  329. 00:06:46,253 --> 00:06:49,298
  330. The engineers test
  331. building prototypes
  332.  
  333. 79
  334. 00:06:49,423 --> 00:06:52,092
  335. on the big shake table.
  336.  
  337. 80
  338. 00:06:52,218 --> 00:06:54,595
  339.  
  340.  
  341. 81
  342. 00:07:00,851 --> 00:07:05,064
  343. To learn more, Menzer studied
  344. countries like Nepal,
  345.  
  346. 82
  347. 00:07:05,189 --> 00:07:07,900
  348. where earthquakes can be severe.
  349.  
  350. 83
  351. 00:07:10,903 --> 00:07:14,365
  352. Nepal is a very poor country,
  353.  
  354. 84
  355. 00:07:14,490 --> 00:07:17,284
  356. where most of the houses were built
  357.  
  358. 85
  359. 00:07:17,409 --> 00:07:20,496
  360. without any engineering design.
  361.  
  362. 86
  363. 00:07:20,621 --> 00:07:22,998
  364.  
  365.  
  366. 87
  367. 00:07:25,251 --> 00:07:27,628
  368.  
  369.  
  370. 88
  371. 00:07:35,511 --> 00:07:40,516
  372. Stone houses, they're an
  373. accident waiting to happen.
  374.  
  375. 89
  376. 00:07:42,601 --> 00:07:44,311
  377. In 2015,
  378.  
  379. 90
  380. 00:07:44,436 --> 00:07:47,106
  381. a massive earthquake struck Nepal.
  382.  
  383. 91
  384. 00:07:48,983 --> 00:07:51,193
  385.  
  386.  
  387. 92
  388. 00:07:51,318 --> 00:07:53,654
  389.  
  390.  
  391. 93
  392. 00:07:59,243 --> 00:08:01,579
  393.  
  394.  
  395. 94
  396. 00:08:03,581 --> 00:08:07,543
  397. 8,000 lost their lives.
  398.  
  399. 95
  400. 00:08:07,668 --> 00:08:10,045
  401. But some survived.
  402.  
  403. 96
  404. 00:08:12,006 --> 00:08:15,009
  405. Including the miracle baby,
  406.  
  407. 97
  408. 00:08:15,134 --> 00:08:17,970
  409. buried in the rubble for 22 hours.
  410.  
  411. 98
  412. 00:08:18,095 --> 00:08:20,723
  413.  
  414.  
  415. 99
  416. 00:08:22,850 --> 00:08:26,645
  417. To do her part,
  418. Menzer took time off from work
  419.  
  420. 100
  421. 00:08:26,770 --> 00:08:28,480
  422. and flew to Nepal
  423.  
  424. 101
  425. 00:08:28,606 --> 00:08:32,484
  426. to join a team
  427. of fact-finding engineers.
  428.  
  429. 102
  430. 00:08:32,610 --> 00:08:35,362
  431. We collect data on ground failures
  432.  
  433. 103
  434. 00:08:35,487 --> 00:08:38,198
  435. before the evidence washes away.
  436.  
  437. 104
  438. 00:08:38,324 --> 00:08:41,452
  439. We need to work fast.
  440.  
  441. 105
  442. 00:08:41,577 --> 00:08:43,579
  443.  
  444.  
  445. 106
  446. 00:08:43,704 --> 00:08:46,540
  447. (speaking foreign language)
  448. Namaste. Namaste.
  449.  
  450. 107
  451. 00:08:46,665 --> 00:08:48,751
  452. Namaste. Namaste.
  453.  
  454. 108
  455. 00:08:48,876 --> 00:08:52,755
  456. Different types of soils
  457. act differently.
  458.  
  459. 109
  460. 00:08:52,880 --> 00:08:55,049
  461. Some soils act like a Jell-0.
  462.  
  463. 110
  464. 00:08:55,174 --> 00:08:57,885
  465. Others act like a liquid
  466.  
  467. 111
  468. 00:08:58,010 --> 00:09:02,222
  469. and lose all their strength.
  470.  
  471. 112
  472. 00:09:03,557 --> 00:09:05,184
  473. Farmers led us to a field,
  474.  
  475. 113
  476. 00:09:05,309 --> 00:09:08,562
  477. where carrots popped
  478. out of the ground--
  479.  
  480. 114
  481. 00:09:08,687 --> 00:09:11,940
  482. a clue that this soil
  483. acted like a liquid
  484.  
  485. 115
  486. 00:09:12,066 --> 00:09:15,402
  487. during the earthquake.
  488.  
  489. 116
  490. 00:09:15,527 --> 00:09:18,280
  491. That's what we call liquefaction.
  492.  
  493. 117
  494. 00:09:21,909 --> 00:09:23,952
  495. I remember when I was 13.
  496.  
  497. 118
  498. 00:09:24,078 --> 00:09:26,330
  499. I know what these kids
  500. are going through.
  501.  
  502. 119
  503. 00:09:26,455 --> 00:09:28,791
  504.  
  505.  
  506. 120
  507. 00:09:32,294 --> 00:09:34,338
  508. The emotional aftershock
  509. of an earthquake
  510.  
  511. 121
  512. 00:09:34,463 --> 00:09:36,840
  513. can last for years.
  514.  
  515. 122
  516. 00:09:39,593 --> 00:09:42,846
  517. This is why I became an engineer.
  518.  
  519. 123
  520. 00:09:42,971 --> 00:09:45,307
  521.  
  522.  
  523. 124
  524. 00:09:48,394 --> 00:09:50,104
  525. After leaving Nepal,
  526.  
  527. 125
  528. 00:09:50,229 --> 00:09:53,148
  529. Menzer went to San Francisco.
  530.  
  531. 126
  532. 00:09:53,273 --> 00:09:54,608
  533.  
  534.  
  535. 127
  536. 00:09:54,733 --> 00:09:58,237
  537. Here, engineers had
  538. a unique challenge--
  539.  
  540. 128
  541. 00:09:58,362 --> 00:09:59,780
  542. designing the city's
  543. tallest skyscraper
  544.  
  545. 129
  546. 00:10:00,906 --> 00:10:04,159
  547. at a site prone to liquefaction.
  548.  
  549. 130
  550. 00:10:04,284 --> 00:10:08,706
  551. The engineers solved it
  552. from the ground up.
  553.  
  554. 131
  555. 00:10:08,831 --> 00:10:11,208
  556.  
  557.  
  558. 132
  559. 00:10:22,511 --> 00:10:24,847
  560. Menzer's team tours the site,
  561.  
  562. 133
  563. 00:10:24,972 --> 00:10:28,016
  564. where engineers sunk
  565. massive concrete columns
  566.  
  567. 134
  568. 00:10:28,142 --> 00:10:30,477
  569. all the way down to bedrock
  570.  
  571. 135
  572. 00:10:30,602 --> 00:10:32,187
  573. to resist earthquakes.
  574.  
  575. 136
  576. 00:10:32,312 --> 00:10:35,566
  577.  
  578.  
  579. 137
  580. 00:10:35,691 --> 00:10:38,318
  581. Keeping people safe
  582.  
  583. 138
  584. 00:10:38,444 --> 00:10:41,989
  585. has always been the heart
  586. and soul of engineering.
  587.  
  588. 139
  589. 00:10:42,114 --> 00:10:44,450
  590. II'
  591.  
  592. 140
  593. 00:10:57,963 --> 00:10:58,116
  594. The first emperor of China
  595. faced a problem:
  596.  
  597. 141
  598. 00:11:03,496 --> 00:11:07,959
  599. Mongol warriors were invading
  600. from the north.
  601.  
  602. 142
  603. 00:11:08,084 --> 00:11:11,045
  604. So the emperor's engineers
  605. began building something
  606.  
  607. 143
  608. 00:11:11,170 --> 00:11:13,381
  609. that would preserve
  610. their civilization
  611.  
  612. 144
  613. 00:11:13,506 --> 00:11:16,843
  614. for almost 2,000 years.
  615.  
  616. 145
  617. 00:11:18,678 --> 00:11:20,638
  618.  
  619.  
  620. 146
  621. 00:11:27,770 --> 00:11:32,770
  622. The Great Wall grew to be
  623. 13,000 miles long...
  624.  
  625. 147
  626. 00:11:33,323 --> 00:11:37,244
  627. the largest structure
  628. ever built by humans.
  629.  
  630. 148
  631. 00:11:39,872 --> 00:11:43,083
  632. After centuries of erosion
  633. and earthquakes,
  634.  
  635. 149
  636. 00:11:43,208 --> 00:11:46,003
  637. much of the wall survives.
  638.  
  639. 150
  640. 00:11:49,298 --> 00:11:52,134
  641. Steve Burrows,
  642. an engineer from England,
  643.  
  644. 151
  645. 00:11:52,259 --> 00:11:54,928
  646. has come to investigate.
  647.  
  648. 152
  649. 00:11:56,471 --> 00:11:58,140
  650. It's really tough to study the wall
  651.  
  652. 153
  653. 00:11:58,265 --> 00:12:00,017
  654. when it stands there
  655. right on a knife edge
  656.  
  657. 154
  658. 00:12:00,142 --> 00:12:01,894
  659. on the top of a mountain.
  660.  
  661. 155
  662. 00:12:02,019 --> 00:12:05,022
  663. But we have our ways.
  664.  
  665. 156
  666. 00:12:10,277 --> 00:12:12,696
  667. This is lidar,
  668.  
  669. 157
  670. 00:12:12,821 --> 00:12:14,740
  671. the laser imaging device.
  672.  
  673. 158
  674. 00:12:24,583 --> 00:12:27,836
  675. The lidar showed that the most
  676. precisely built parts
  677.  
  678. 159
  679. 00:12:27,961 --> 00:12:30,047
  680. are standing well today.
  681.  
  682. 160
  683. 00:12:32,674 --> 00:12:36,094
  684. However, miles away, badly
  685. built sections of the wall
  686.  
  687. 161
  688. 00:12:36,219 --> 00:12:38,305
  689. are also still standing.
  690.  
  691. 162
  692. 00:12:38,430 --> 00:12:40,390
  693. Why?
  694.  
  695. 163
  696. 00:12:42,851 --> 00:12:45,395
  697. 500 years ago,
  698. the builders added
  699.  
  700. 164
  701. 00:12:45,520 --> 00:12:50,609
  702. a secret ingredient
  703. to their mortar:
  704.  
  705. 165
  706. 00:12:50,734 --> 00:12:53,528
  707. sticky rice.
  708.  
  709. 166
  710. 00:12:57,783 --> 00:13:00,285
  711. Adding sticky rice and lime
  712. to the mortar,
  713.  
  714. 167
  715. 00:13:00,410 --> 00:13:01,954
  716. it makes the mortar more elastic
  717.  
  718. 168
  719. 00:13:02,079 --> 00:13:05,540
  720. 'cause it allows the wall
  721. to stretch and contract
  722.  
  723. 169
  724. 00:13:05,666 --> 00:13:08,043
  725. depending on the temperature.
  726.  
  727. 170
  728. 00:13:10,337 --> 00:13:13,507
  729. Sometimes the best solution
  730.  
  731. 171
  732. 00:13:13,632 --> 00:13:16,093
  733. is the simplest--
  734.  
  735. 172
  736. 00:13:16,218 --> 00:13:17,636
  737. the one staring up at you
  738.  
  739. 173
  740. 00:13:17,761 --> 00:13:19,805
  741. from your dinner plate.
  742.  
  743. 174
  744. 00:13:24,601 --> 00:13:27,688
  745. In western China,
  746.  
  747. 175
  748. 00:13:27,813 --> 00:13:30,983
  749. across the highest bridges
  750. on Earth,
  751.  
  752. 176
  753. 00:13:31,108 --> 00:13:34,945
  754. people are moving
  755. from farms to cities.
  756.  
  757. 177
  758. 00:13:37,030 --> 00:13:41,868
  759. Shanghai is now the most
  760. populous city in the world--
  761.  
  762. 178
  763. 00:13:41,994 --> 00:13:44,997
  764. 24 million people.
  765.  
  766. 179
  767. 00:13:45,122 --> 00:13:46,873
  768.  
  769.  
  770. 180
  771. 00:13:46,999 --> 00:13:49,668
  772. But there's a problem.
  773.  
  774. 181
  775. 00:13:49,793 --> 00:13:53,213
  776. No more space to build.
  777.  
  778. 182
  779. 00:13:53,338 --> 00:13:56,174
  780. Where can they all live?
  781.  
  782. 183
  783. 00:13:56,299 --> 00:13:58,260
  784.  
  785.  
  786. 184
  787. 00:14:05,350 --> 00:14:08,228
  788. Engineers squeezed
  789. an entire urban district
  790.  
  791. 185
  792. 00:14:08,353 --> 00:14:10,772
  793. into one city block...
  794.  
  795. 186
  796. 00:14:10,897 --> 00:14:13,150
  797. by going vertical.
  798.  
  799. 187
  800. 00:14:16,570 --> 00:14:19,531
  801. They envisioned
  802. China's tallest building,
  803.  
  804. 188
  805. 00:14:19,656 --> 00:14:21,908
  806. the Shanghai Tower,
  807.  
  808. 189
  809. 00:14:22,034 --> 00:14:24,202
  810. rising 128 floors high
  811.  
  812. 190
  813. 00:14:24,327 --> 00:14:27,748
  814. with space for 16,000 people.
  815.  
  816. 191
  817. 00:14:30,417 --> 00:14:32,544
  818. But the taller the structure,
  819.  
  820. 192
  821. 00:14:32,669 --> 00:14:36,173
  822. the more it flirts
  823. with Mother Nature.
  824.  
  825. 193
  826. 00:14:36,298 --> 00:14:38,341
  827.  
  828.  
  829. 194
  830. 00:14:38,467 --> 00:14:39,843
  831. Each summer,
  832.  
  833. 195
  834. 00:14:39,968 --> 00:14:43,138
  835. typhoons blast the city.
  836.  
  837. 196
  838. 00:14:43,263 --> 00:14:44,639
  839. The Shanghai Tower would soon
  840.  
  841. 197
  842. 00:14:44,765 --> 00:14:47,142
  843. become a huge target.
  844.  
  845. 198
  846. 00:14:48,769 --> 00:14:50,687
  847. But the engineers had
  848.  
  849. 199
  850. 00:14:50,812 --> 00:14:52,814
  851. some tricks up their sleeve.
  852.  
  853. 200
  854. 00:14:55,525 --> 00:14:59,738
  855. By twisting the outer skin
  856. 120 degrees,
  857.  
  858. 201
  859. 00:14:59,863 --> 00:15:03,825
  860. the wind safely glides
  861. around the tower.
  862.  
  863. 202
  864. 00:15:06,661 --> 00:15:08,955
  865. Here, the problem
  866. of population density
  867.  
  868. 203
  869. 00:15:09,081 --> 00:15:10,874
  870. has been met.
  871.  
  872. 204
  873. 00:15:10,999 --> 00:15:13,585
  874. All thanks to the ingenuity
  875.  
  876. 205
  877. 00:15:13,710 --> 00:15:16,046
  878. of a twist.
  879.  
  880. 206
  881. 00:15:20,884 --> 00:15:23,470
  882. Wind is an intriguing chaflenge
  883.  
  884. 207
  885. 00:15:23,595 --> 00:15:26,348
  886. for engineers of all ages.
  887.  
  888. 208
  889. 00:15:26,473 --> 00:15:29,601
  890. Menzer makes a game of it.
  891.  
  892. 209
  893. 00:15:29,726 --> 00:15:32,813
  894. Okay, this competition
  895. will count as ten points.
  896.  
  897. 210
  898. 00:15:32,938 --> 00:15:35,440
  899. And the tallest skyscraper
  900. that resists the wind
  901.  
  902. 211
  903. 00:15:35,565 --> 00:15:37,442
  904. will get five extra.
  905.  
  906. 212
  907. 00:15:37,567 --> 00:15:39,111
  908. Yay! Excited?
  909.  
  910.  
  911. 213
  912. 00:15:39,236 --> 00:15:40,570
  913. All right.
  914.  
  915. 214
  916. 00:15:40,695 --> 00:15:43,949
  917.  
  918.  
  919. 215
  920. 00:15:44,074 --> 00:15:46,535
  921. Now, remember, planning is important.
  922.  
  923. 216
  924. 00:15:46,660 --> 00:15:48,286
  925. Before cutting...
  926.  
  927. 217
  928. 00:15:48,411 --> 00:15:51,373
  929. make sure what you're building.
  930.  
  931. 218
  932. 00:15:51,498 --> 00:15:54,000
  933.  
  934.  
  935. 219
  936. 00:15:54,126 --> 00:15:55,836
  937. Building these paper skyscrapers
  938.  
  939. 220
  940. 00:15:55,961 --> 00:15:59,256
  941. teach kids the most
  942. important thing...
  943.  
  944. 221
  945. 00:15:59,381 --> 00:16:01,466
  946. engineering is fun.
  947.  
  948. 222
  949. 00:16:01,591 --> 00:16:03,969
  950.  
  951.  
  952. 223
  953. 00:16:08,348 --> 00:16:09,808
  954. Oh, it's getting...
  955.  
  956. 224
  957. 00:16:09,933 --> 00:16:12,310
  958. Oh, no!
  959.  
  960. 225
  961. 00:16:14,604 --> 00:16:16,231
  962. In 1940,
  963.  
  964. 226
  965. 00:16:16,356 --> 00:16:20,569
  966. the newly opened Tacoma
  967. Narrows Bridge, near Seattle,
  968.  
  969. 227
  970. 00:16:20,694 --> 00:16:24,865
  971. earned the nickname Galloping Gertie.
  972.  
  973. 228
  974. 00:16:29,494 --> 00:16:31,454
  975.

  1020. 239
  1021. 00:17:10,368 --> 00:17:14,080

  1066. 250
  1067. 00:17:41,691 --> 00:17:44,236

  1071. 251
  1072. 00:17:44,361 --> 00:17:47,614

  1076. 252
  1077. 00:17:47,739 --> 00:17:49,157

  1084. 254
  1085. 00:17:50,909 --> 00:17:53,203

  1088. 255
  1089. 00:17:53,328 --> 00:17:55,372
  1090. Over the past decade,

  1092. 256
  1093. 00:17:55,497 --> 00:18:00,210

  1097. 257
  1098. 00:18:06,549 --> 00:18:08,343

  1106. 259
  1107. 00:18:12,097 --> 00:18:16,643

  1109. in this bridge.
  1110.  
  1111. 260
  1112. 00:18:17,936 --> 00:18:19,896
  1113. Three years ago,
  1114.  
  1115. 261
  1116. 00:18:20,021 --> 00:18:22,482
  1117. when our youngest girl
  1118. needed medicine,
  1119.  
  1120. 262
  1121. 00:18:22,607 --> 00:18:25,110
  1122. Mathilde, my wife, headed off
  1123.  
  1124. 263
  1125. 00:18:25,235 --> 00:18:27,862
  1126. to the clinic across the river.
  1127.  
  1128. 264
  1129. 00:18:31,783 --> 00:18:34,828
  1130. The river was very high that day.
  1131.  
  1132. 265
  1133. 00:18:37,872 --> 00:18:40,709
  1134. Now I have eight children

  1147.  
  1148. 269
  1149. 00:18:49,592 --> 00:18:51,928
  1150. right where their mother drowned.
  1151.  
  1152. 270
  1153. 00:19:00,186 --> 00:19:02,897
  1154. Mathilde was everything
  1155. to them.
  1156.  
  1157. 271
  1158. 00:19:07,277 --> 00:19:09,612
  1159. They needed a bridge.
  1160.  
  1161. 272
  1162. 00:19:12,073 --> 00:19:15,535
  1163. At least, it's going to be
  1164. a really big bridge.
  1165.  
  1166. 273
  1167. 00:19:15,660 --> 00:19:16,995
  1168. Our mantra
  1169.  
  1170. 274
  1171. 00:19:17,120 --> 00:19:19,289
  1172. is "Keep it simple."

  1174. 275
  1175. 00:19:19,414 --> 00:19:22,417

  1179. 276
  1180. 00:19:22,542 --> 00:19:24,753
  1181. the crew can raise tall towers,

  1183. 277
  1184. 00:19:24,878 --> 00:19:26,713

  1882. 00:27:30,523 --> 00:27:32,609
  1883. Fredi Lajvardi.
  1884.  
  1885. 437
  1886. 00:27:32,734 --> 00:27:34,986
  1887. So I see one way
  1888. you could solve this.
  1889.  
  1890. 438
  1891. 00:27:35,111 --> 00:27:37,030
  1892. You could stop your catapult...
  1893.  
  1894. 439
  1895. 00:27:37,155 --> 00:27:40,033
  1896. I joined his
  1897. after-school robotics class
  1898.  
  1899. 440
  1900. 00:27:40,158 --> 00:27:43,578
  1901. and the problems
  1902. weren't easy to solve,
  1903.  
  1904. 441
  1905. 00:27:43,703 --> 00:27:46,372
  1906. but Fredi always knew
  1907. how to make it fun.
  1908.  
  1909. 442
  1910. 00:27:46,497 --> 00:27:48,666
  1911. That will leave you
  1912. with a higher trajectory...
  1913.  
  1914. 443
  1915. 00:27:48,791 --> 00:27:51,169
  1916. You're doing a good job.
  1917.  
  1918. 444
  1919. 00:27:51,294 --> 00:27:52,879
  1920.  
  1921.  
  1922. 445
  1923. 00:27:53,004 --> 00:27:55,423
  1924. The kids were just
  1925. having so much fun.
  1926.  
  1927. 446
  1928. 00:27:55,548 --> 00:27:57,008
  1929. They were learning so much.
  1930.  
  1931. 447
  1932. 00:27:57,133 --> 00:27:58,343
  1933. They didn't even realize
  1934. that they were learning
  1935.  
  1936. 448
  1937. 00:27:58,468 --> 00:27:59,761
  1938. and that was the best part.
  1939.  
  1940. 449
  1941. 00:27:59,886 --> 00:28:01,346
  1942.  
  1943.  
  1944. 450
  1945. 00:28:01,471 --> 00:28:03,264
  1946. Good catch!
  1947.  
  1948. 451
  1949. 00:28:03,389 --> 00:28:04,474
  1950. Awesome.
  1951.  
  1952. 452
  1953. 00:28:04,599 --> 00:28:05,975
  1954. They heard about
  1955.  
  1956. 453
  1957. 00:28:06,100 --> 00:28:08,144
  1958. a national underwater
  1959. robotics competition
  1960.  
  1961. 454
  1962. 00:28:08,269 --> 00:28:09,562
  1963. in Santa Barbara, California.
  1964.  
  1965. 455
  1966. 00:28:09,687 --> 00:28:12,732
  1967. And, on a whim,
  1968.  
  1969. 456
  1970. 00:28:12,857 --> 00:28:14,692
  1971. decided to enter.
  1972.  
  1973. 457
  1974. 00:28:14,817 --> 00:28:16,319
  1975. Heads up!
  1976.  
  1977. 458
  1978. 00:28:16,444 --> 00:28:18,363
  1979. We didn't have much funding.
  1980.  
  1981. 459
  1982. 00:28:18,488 --> 00:28:20,990
  1983. But if you can't be expensive,
  1984.  
  1985. 460
  1986. 00:28:21,115 --> 00:28:22,408
  1987. be clever.
  1988.  
  1989. 461
  1990. 00:28:22,533 --> 00:28:25,578
  1991. So we used cheap landscaping pipe.
  1992.  
  1993. 462
  1994. 00:28:25,703 --> 00:28:28,414
  1995. In Robotics Club,
  1996. Fredi taught us a system:
  1997.  
  1998. 463
  1999. 00:28:28,539 --> 00:28:31,542
  2000. to find the problem, come up
  2001. with different solutions
  2002.  
  2003. 464
  2004. 00:28:31,668 --> 00:28:34,003
  2005. and pick the best one.
  2006.  
  2007. 465
  2008. 00:28:36,923 --> 00:28:38,883
  2009. But the one problem
  2010. we couldn't solve
  2011.  
  2012. 466
  2013. 00:28:39,008 --> 00:28:42,262
  2014. was the smell of the pipe glue.
  2015.  
  2016. 467
  2017. 00:28:42,387 --> 00:28:45,431
  2018. It just stunk.
  2019.  
  2020. 468
  2021. 00:28:45,556 --> 00:28:49,185
  2022. So we named our robot Stinky.
  2023.  
  2024. 469
  2025. 00:28:49,310 --> 00:28:51,604
  2026.  
  2027.  
  2028. 470
  2029. 00:28:51,729 --> 00:28:54,107
  2030. - It's working, yeah.
  2031. - Yes.
  2032.  
  2033. 471
  2034. 00:28:54,232 --> 00:28:55,441
  2035. Stinky was a bunch of pipe
  2036.  
  2037. 472
  2038. 00:28:55,566 --> 00:28:57,860
  2039. with a little bit of CPU
  2040.  
  2041. 473
  2042. 00:28:57,986 --> 00:29:00,697
  2043. and a whale lot of cables.
  2044.  
  2045. 474
  2046. 00:29:05,159 --> 00:29:08,496
  2047. Six months and $800 later,
  2048.  
  2049. 475
  2050. 00:29:08,621 --> 00:29:11,165
  2051. Stinky was ready to go.
  2052.  
  2053. 476
  2054. 00:29:11,291 --> 00:29:13,334
  2055. Here, guys,
  2056. let's, uh, hurry up
  2057.  
  2058. 477
  2059. 00:29:13,459 --> 00:29:15,044
  2060. and get Stinky in here.
  2061.  
  2062. 478
  2063. 00:29:15,169 --> 00:29:17,588
  2064. Sadly, Angelica
  2065. had work commitments,
  2066.  
  2067. 479
  2068. 00:29:17,714 --> 00:29:19,424

  2288. 531
  2289. 00:31:44,610 --> 00:31:46,904
  2290. It wouldn't go up
  2291. when they wanted it to go up.
  2292.  
  2293. 532
  2294. 00:31:54,704 --> 00:31:57,290
  2295. We had to figure out
  2296. what was going on.
  2297.  
  2298. 533
  2299. 00:32:01,002 --> 00:32:03,629

  2307. 535
  2308. 00:32:10,803 --> 00:32:12,085
  2309. We had a small leak
  2310. but no clue where it was.

  2312. 536
  2313. 00:32:12,086 --> 00:32:21,357

  2315. what can we do?
  2316.  
  2317. 537
  2318. 00:32:24,068 --> 00:32:26,112
  2319. And then Lorenzo asked everybody,
  2320.  
  2321. 538
  2322. 00:32:26,237 --> 00:32:29,407
  2323. "Aren't tampons really absorbent?"

  2325. 539
  2326. 00:32:31,242 --> 00:32:34,287

  2330. 540
  2331. 00:32:34,412 --> 00:32:36,247
  2332. - I got 'em!
  2333. - Yeah! -Yes!
  2334.  
  2335. 541
  2336. 00:32:39,834 --> 00:32:41,878
  2337. It wasn't about building a robot.
  2338.  
  2339. 542
  2340. 00:32:42,003 --> 00:32:44,964
  2341. It was about learning
  2342. how to learn for yourself.
  2343.  
  2344. 543
  2345. 00:32:48,468 --> 00:32:51,846
  2346. The boys arrived
  2347. at the competition exhausted,
  2348.  
  2349. 544
  2350. 00:32:51,971 --> 00:32:53,556
  2351. without a chance to test Stinky.
  2352.  
  2353. 545
  2354. 00:32:53,681 --> 00:32:55,558
  2355. Carl Hayden High School,
  2356.  
  2357. 546
  2358. 00:32:55,683 --> 00:32:57,268
  2359. - you have one minute.
  2360. - Let's go, guys!
  2361.  
  2362. 547
  2363. 00:32:57,393 --> 00:32:58,978
  2364. Do it! You can do it!
  2365.  
  2366. 548
  2367. 00:32:59,103 --> 00:33:02,023
  2368. We had no idea
  2369. if the solution would work.
  2370.  
  2371. 549
  2372. 00:33:19,290 --> 00:33:23,753
  2373. Thanks to a wild idea,
  2374. Stinky was working again.
  2375.  
  2376. 550
  2377. 00:33:26,088 --> 00:33:30,968
  2378. The boys had 30 minutes
  2379. to complete ten tasks.
  2380.  
  2381. 551
  2382. 00:33:34,305 --> 00:33:39,352
  2383. The college teams had a laser
  2384. to measure distances.
  2385.  
  2386. 552
  2387. 00:33:39,477 --> 00:33:42,438
  2388. Carl Hayden couldn't afford one.
  2389.  
  2390. 553
  2391. 00:33:45,399 --> 00:33:47,777
  2392. They used a tape measure instead.
  2393.  
  2394. 554
  2395. 00:34:00,081 --> 00:34:01,624
  2396. The hardest task
  2397.  
  2398. 555
  2399. 00:34:01,749 --> 00:34:04,627
  2400. was to sample a fluid
  2401. from a barrel...
  2402.  
  2403. 556
  2404. 00:34:04,752 --> 00:34:06,546
  2405. with a tube.
  2406.  
  2407. 557
  2408. 00:34:08,589 --> 00:34:11,551
  2409. Most of the teams
  2410. didn't even attempt it.
  2411.  
  2412. 558
  2413. 00:34:13,594 --> 00:34:15,012
  2414. When we went straight to it,
  2415.  
  2416. 559
  2417. 00:34:15,137 --> 00:34:16,472
  2418. it just-just fell into it,
  2419.  
  2420. 560
  2421. 00:34:16,597 --> 00:34:19,559
  2422. like it was meant to be
  2423. or something.
  2424.  
  2425. 561
  2426. 00:34:28,859 --> 00:34:30,486
  2427. At the awards banquet,
  2428.  
  2429. 562
  2430. 00:34:30,611 --> 00:34:33,447
  2431. they heard something
  2432. that surprised everyone.
  2433.  
  2434. 563
  2435. 00:34:33,573 --> 00:34:36,617
  2436. And second place goes to...
  2437.  
  2438. 564
  2439. 00:34:38,244 --> 00:34:42,832
  2440. ...Massachusetts Institute
  2441. of Technology!
  2442.  
  2443. 565
  2444. 00:34:42,957 --> 00:34:44,500
  2445.  
  2446.  
  2447. 566
  2448. 00:34:46,544 --> 00:34:49,505
  2449. MIT got second place.
  2450.  
  2451. 567
  2452. 00:34:52,675 --> 00:34:56,262
  2453. I was thinking, "Who's first?
  2454.  
  2455. 568
  2456. 00:34:56,387 --> 00:34:58,139
  2457. "Oh, man, who's-- who beat MIT?
  2458.  
  2459. 569
  2460. 00:34:58,264 --> 00:35:00,224
  2461. This is, this is gonna be awesome."
  2462.  
  2463. 570
  2464. 00:35:03,477 --> 00:35:05,771
  2465. First place goes to...
  2466.  
  2467. 571
  2468. 00:35:05,896 --> 00:35:09,191
  2469. Carl Hayden High School
  2470. from Phoenix, Arizona!
  2471.  
  2472. 572
  2473. 00:35:09,317 --> 00:35:10,526
  2474.  
  2475.  
  2476. 573
  2477. 00:35:10,651 --> 00:35:12,612
  2478. Oh!
  2479.  
  2480.  
  2481. 574
  2482. 00:35:16,782 --> 00:35:20,077
  2483. It was almost disbelief.
  2484.  
  2485. 575
  2486. 00:35:20,202 --> 00:35:22,496
  2487. Is this a dream or is this for real?
  2488.  
  2489. 576
  2490. 00:35:22,622 --> 00:35:24,957
  2491.  
  2492.  
  2493. 577
  2494. 00:35:29,795 --> 00:35:31,922
  2495. I don't remember walking to the stage,
  2496.  
  2497. 578
  2498. 00:35:32,048 --> 00:35:34,008
  2499. because, you know,
  2500. I was just floating, I think.
  2501.  
  2502. 579
  2503. 00:35:34,133 --> 00:35:36,510
  2504.  
  2505.  
  2506. 580
  2507. 00:35:42,183 --> 00:35:43,392
  2508.  
  2509.  
  2510. 581
  2511. 00:35:45,269 --> 00:35:47,897
  2512. What started out as a crazy idea
  2513.  
  2514. 582
  2515. 00:35:48,022 --> 00:35:50,232
  2516. turned into something so much more.
  2517.  
  2518. 583
  2519. 00:35:52,276 --> 00:35:54,904
  2520. Today, that high school robotics club
  2521.  
  2522. 584
  2523. 00:35:55,029 --> 00:35:58,032
  2524. has grown exponentially,
  2525.  
  2526. 585
  2527. 00:35:58,157 --> 00:36:01,118
  2528. largely thanks to Fredi.
  2529.  
  2530. 586
  2531. 00:36:03,079 --> 00:36:06,916
  2532. Knowing that somebody believes in you,
  2533.  
  2534. 587
  2535. 00:36:07,041 --> 00:36:10,252
  2536. even though you don't
  2537. believe in yourself,
  2538.  
  2539. 588
  2540. 00:36:10,378 --> 00:36:12,797
  2541. even though you doubt
  2542. that you could do something,
  2543.  
  2544. 589
  2545. 00:36:12,922 --> 00:36:16,550
  2546. um, I think, you know, if you
  2547. could find that in somebody,
  2548.  
  2549. 590
  2550. 00:36:16,676 --> 00:36:20,805
  2551. it's just... it's a blessing.
  2552.  
  2553. 591
  2554. 00:36:20,930 --> 00:36:24,892
  2555. It was because of him
  2556. that Angelica went to Stanford.
  2557.  
  2558. 592
  2559. 00:36:26,936 --> 00:36:28,521
  2560. Now my husband Juan and I
  2561.  
  2562. 593
  2563. 00:36:28,646 --> 00:36:31,190
  2564. are both engineers in Phoenix.
  2565.  
  2566. 594
  2567. 00:36:31,315 --> 00:36:34,485
  2568. And, I mean, you never know.
  2569.  
  2570. 595
  2571. 00:36:34,610 --> 00:36:37,571
  2572. Maybe my daughter will be one, too.
  2573.  
  2574. 596
  2575. 00:36:39,990 --> 00:36:42,702
  2576. And any chance I get,
  2577. I like to help
  2578.  
  2579. 597
  2580. 00:36:42,827 --> 00:36:45,705
  2581. my favorite teacher
  2582. inspire future engineers.
  2583.  
  2584. 598
  2585. 00:36:45,830 --> 00:36:47,373
  2586. ...the same thing
  2587. with this one.
  2588.  
  2589. 599
  2590. 00:36:47,498 --> 00:36:49,875
  2591. It's not doing it,
  2592. because it's a triangle.
  2593.  
  2594. 600
  2595. 00:36:50,000 --> 00:36:52,545
  2596. It's very solid.
  2597. It doesn't change shape.
  2598.  
  2599. 601
  2600. 00:36:52,670 --> 00:36:55,172
  2601. So now we want you
  2602. to come up with different ways
  2603.  
  2604. 602
  2605. 00:36:55,297 --> 00:36:57,174
  2606. to make the bridge stronger--
  2607.  
  2608. 603
  2609. 00:36:57,299 --> 00:36:59,218
  2610. so you see the truck
  2611. in front of you--
  2612.  
  2613. 604
  2614. 00:36:59,343 --> 00:37:00,845
  2615. so it can make it
  2616. across the bridge.
  2617.  
  2618. 605
  2619. 00:37:00,970 --> 00:37:02,596
  2620. - You guys want to try that?
  2621. - Yeah!
  2622.  
  2623. 606
  2624. 00:37:02,722 --> 00:37:05,099
  2625. - All right. Let's try it.
  2626. - Hey, let's do it.
  2627.  
  2628. 607
  2629. 00:37:05,224 --> 00:37:08,352
  2630. Well, I think they need
  2631. to try to have more triangles.
  2632.  
  2633. 608
  2634. 00:37:08,477 --> 00:37:12,690
  2635. There's barely any support
  2636. going along the bottom.
  2637.  
  2638. 609
  2639. 00:37:12,815 --> 00:37:15,025
  2640. Yeah, I think they
  2641. should put a sign
  2642.  
  2643. 610
  2644. 00:37:15,151 --> 00:37:18,028
  2645. and say "no trucks allowed."
  2646.  
  2647. 611
  2648. 00:37:18,154 --> 00:37:21,782
  2649. The screw's not stable, period,
  2650. because it fell apart.
  2651.  
  2652. 612
  2653. 00:37:21,907 --> 00:37:24,201
  2654. - The whole bridge.
  2655. - It's not stable at all.
  2656.  
  2657. 613
  2658. 00:37:24,326 --> 00:37:27,997
  2659. We have to remind ourselves
  2660. about budget cost.
  2661.  
  2662. 614
  2663. 00:37:28,122 --> 00:37:31,417
  2664. Yeah, but how about we cross
  2665. that bridge when we come to it?
  2666.  
  2667. 615
  2668. 00:37:31,542 --> 00:37:32,835
  2669. Because I think...
  2670.  
  2671. 616
  2672. 00:37:32,960 --> 00:37:34,837
  2673. Young minds find new paths.
  2674.  
  2675. 617
  2676. 00:37:34,962 --> 00:37:37,256
  2677. It was not physics alone
  2678. that led to
  2679.  
  2680. 618
  2681. 00:37:37,381 --> 00:37:41,594
  2682. the Millau Bridge in France--
  2683. it was art.
  2684.  
  2685. 619
  2686. 00:37:41,719 --> 00:37:44,013
  2687. - That one!
  2688. - That one over there, right?
  2689.  
  2690. 620
  2691. 00:37:44,138 --> 00:37:47,266
  2692. And what are the triangles for?
  2693.  
  2694. 621
  2695. 00:37:47,391 --> 00:37:50,686
  2696. Young minds will shape our future.
  2697.  
  2698. 622
  2699. 00:37:50,811 --> 00:37:54,190
  2700. - It provides, uh, stability,
  2701. - right? - Yeah.
  2702.  
  2703. 623
  2704. 00:37:58,235 --> 00:38:00,196
  2705.  
  2706.  
  2707. 624
  2708. 00:38:01,989 --> 00:38:03,949
  2709.  
  2710.  
  2711. 625
  2712. 00:38:17,963 --> 00:38:19,924
  2713.  
  2714.  
  2715. 626
  2716. 00:38:29,975 --> 00:38:32,269
  2717. Some young engineers have a bold dream
  2718.  
  2719. 627
  2720. 00:38:32,394 --> 00:38:34,522
  2721. to revolutionize transportation.
  2722.  
  2723. 628
  2724. 00:38:34,647 --> 00:38:38,108
  2725. It's called Hyperloop.
  2726.  
  2727. 629
  2728. 00:38:38,234 --> 00:38:41,320
  2729. If they succeed, they'll allow us
  2730.  
  2731. 630
  2732. 00:38:41,445 --> 00:38:44,782
  2733. to travel 700 miles per hour.
  2734.  
  2735. 631
  2736. 00:38:48,202 --> 00:38:50,579
  2737.  
  2738.  
  2739. 632
  2740. 00:38:52,206 --> 00:38:57,206
  2741. That's from I.A. to
  2742. San Francisco in 30 minutes.
  2743.  
  2744. 633
  2745. 00:39:00,339 --> 00:39:04,802
  2746. By the end of the century,
  2747. 90% of us will live in cities,
  2748.  
  2749. 634
  2750. 00:39:04,927 --> 00:39:07,805
  2751. an exciting challenge for engineers.
  2752.  
  2753. 635
  2754. 00:39:07,930 --> 00:39:09,890
  2755.  
  2756.  
  2757. 636
  2758. 00:39:23,154 --> 00:39:25,030
  2759. The bigger cities get,
  2760.  
  2761. 637
  2762. 00:39:25,156 --> 00:39:28,117
  2763. the smarter they'll need to become.
  2764.  
  2765. 638
  2766. 00:39:29,577 --> 00:39:31,454
  2767. This new transportation hub
  2768.  
  2769. 639
  2770. 00:39:31,579 --> 00:39:31,686
  2771. in San Francisco will feature
  2772. a network of wireless sensors.
  2773.  
  2774. 640
  2775. 00:39:36,941 --> 00:39:38,818
  2776. This will make it safer,
  2777.  
  2778. 641
  2779. 00:39:38,943 --> 00:39:40,486
  2780. more energy-efficient,
