Transcript
| 00:09 | you and I , we've been engineering for a while | |
| 00:12 | now at this point you all deserve your own hard | |
| 00:14 | hats because you guys are pros that treehouse we designed | |
| 00:17 | . I've been spending a ton of time in there | |
| 00:19 | , I've got beanbags , bookshelf stacks of snacks . | |
| 00:22 | It is paradise . Thanks for helping me build it | |
| 00:25 | . And remember if you had another idea for a | |
| 00:27 | space to hang out and send it my way , | |
| 00:28 | I totally want to see what you came up with | |
| 00:30 | . But this time we've got bigger projects to think | |
| 00:32 | about keyword here , how big as big as your | |
| 00:36 | hometown because this time we don't want to just design | |
| 00:39 | an invention or a building . We want to design | |
| 00:43 | an entire city . It's a massive challenge that only | |
| 00:46 | the very best and brightest can take on . And | |
| 00:48 | I'm enlisting you . How can we use engineering to | |
| 00:51 | design a city that is safe , healthy , sustainable | |
| 00:54 | and fun to live in this kind of engineering called | |
| 01:01 | urban planning requires a lot of complicated interlocking variables . | |
| 01:05 | It's a huge project . So where do we start | |
| 01:09 | ? Say it with me , the engineering process , | |
| 01:11 | Let's define our problem . We need a place to | |
| 01:14 | put people , we need that space to fulfill their | |
| 01:16 | needs , things like food , water , shelter , | |
| 01:19 | and also just places to have fun and we need | |
| 01:21 | a space to respect the natural environment where it exists | |
| 01:25 | . Sounds simple enough , but when you're planning a | |
| 01:27 | city , there are lots of things to think about | |
| 01:30 | . How will people move around the city ? Where | |
| 01:32 | will they go to have each of their different needs | |
| 01:34 | met ? So next we have to consider solutions . | |
| 01:38 | Since the city is such a massive project , there | |
| 01:40 | are a ridiculously large number of problems in an even | |
| 01:44 | ridiculously larger number of solutions . So I want you | |
| 01:48 | to build and test your own prototype for a city | |
| 01:52 | . Think through the trials , you might run in | |
| 01:56 | the variables you need to test and then start designing | |
| 02:00 | . Where do you start first ? Think about the | |
| 02:02 | things that you like about where you live . Maybe | |
| 02:04 | your city has a park that you really like , | |
| 02:06 | or there's a public pool with a super cool slide | |
| 02:09 | . Then think about some things in your city that | |
| 02:11 | you don't like . Do you wish you could walk | |
| 02:13 | or bike to get to school instead of riding a | |
| 02:15 | bus ? This is a great way to start thinking | |
| 02:17 | about planning the job of a city planners to create | |
| 02:20 | places for people to live . That makes them happy | |
| 02:23 | . Now , let's get to specifics as city planners | |
| 02:25 | , we want to plan our city somewhere , decide | |
| 02:28 | where yours will be on a mountain , near a | |
| 02:31 | river by the beach . How does its location affect | |
| 02:33 | its resources ? For instance , if your city is | |
| 02:35 | in a desert , you'll need to pump in water | |
| 02:37 | from somewhere else , a city planner needs to plan | |
| 02:39 | for the future to consider what you do . If | |
| 02:41 | lots of people move to your city , will you | |
| 02:43 | build lots of small buildings for them , each on | |
| 02:45 | its own plot of land , cutting into the nature | |
| 02:47 | around you or would you build buildings higher or even | |
| 02:50 | go underground ? Next think about how you divide up | |
| 02:52 | your city . Cities have neighborhoods so people can get | |
| 02:55 | what they need without having to go too far . | |
| 02:58 | Once you've divided your city , decide where you'll put | |
| 03:00 | things like grocery stores , schools , airports , train | |
| 03:03 | stations , doctor's offices , post offices and parks and | |
| 03:06 | then think about how people will get there . Will | |
| 03:08 | they take a bus ? If so ? You'll need | |
| 03:10 | lots of roads . Will they take a subway ? | |
| 03:12 | Better put it in the plan ? Maybe they can | |
| 03:14 | bike then put in some bike paths to , and | |
| 03:17 | hey , don't forget sidewalks . Now take a look | |
| 03:24 | at the city you've created . Will your residents be | |
| 03:26 | happy and healthy ? Will they be able to shop | |
| 03:28 | for groceries male their mail and go to work in | |
| 03:30 | this space ? Is your city good for the environment | |
| 03:33 | to by respecting the surrounding nature . Cities are really | |
| 03:36 | complicated feats of engineering . There's so much to consider | |
| 03:39 | , but I trust you to do a great job | |
| 03:41 | . You've had a ton of training and you've rocked | |
| 03:42 | it so far . So do me a favor . | |
| 03:44 | Please send us a picture of the city you've created | |
| 03:47 | and let us know how you use the engineering process | |
| 03:49 | to create it . Building a hang lighter to get | |
| 03:51 | across the gorge . So that's one thing a flying | |
| 03:53 | robot . Pretty awesome . A treehouse better still but | |
| 03:56 | a city with this project , you'll have really earned | |
| 03:59 | your hard hat for sure . |
