All language subtitles for Dream Big Engineering Our World DOC. 2017

FA“

Children learn by doing,

by building,

by creating.

Those of us who dream big

can carry that joy
of creativity

all through our lives.

Bechtel is proud to present

"Dream Big."

002, -001, 002.

Okay, attitude 25.10,
pitch 64.18 plus 002.

I.“

We never really saw our world

until they showed it to us.

I.“

Through the power
of imagination,

they astonish us.

They're called engineers.

With each
life-changing creation,

like the International
Space Station,

engineers enhance
the human experience.

They build civilizations.

Every bridge,
every building grows

from an engineer's
imagination.

There are now
seven billion of us.

And by 2045,

there will be two billion more.

Where will we all live?

Will we have enough
clean energy?

The boldest solutions

start with the biggest dreams.

Menzer Pehlivan

grew up in Turkey.

I was a girly girl.

I was a lead in schools plays.

I actually wanted to be
an actress.

Until I was 13,
when everything changed.

We lived in
a high-rise building.

I remember my mother
waking me up,

terrified that the building
would come down.

I remember watching
the people suffering.

From that moment on,
I knew what I wanted to do.

Today, I'm a professional
engineer in Seattle,

hoping to make structures
safer during earthquakes.

I love my job.

And I want kids to be
excited about engineering

as much as I am.

So, are you ready
for the earthquake?

- Yeah!
- Yeah?

Three, two, one.

Let's start slow.

- Which one is...
- Go faster.

To design safer buildings,

we study how soil moves
during an earthquake.

The engineers test
building prototypes

on the big shake table.

To learn more, Menzer studied
countries like Nepal,

where earthquakes
can be severe.

Nepal is a very poor country,

where most of the houses
were built

without any
engineering design.

I.“

Stone houses, they're an
accident waiting to happen.

In 2015,

a massive earthquake
struck Nepal.

8,000 lost their lives.

But some survived.

Including the miracle baby,

buried in the rubble
for 22 hours.

To do her part,
Menzer took time off from work

and flew to Nepal

to join a team
of fact-finding engineers.

We collect data
on ground failures

before the evidence
washes away.

We need to work fast.

I.“

Namaste. Namaste.

Namaste. Namaste.

Different types of soils
act differently.

Some soils act like a Jell-0.

Others act like a liquid

and lose all their strength.

Farmers led us to a field,

where carrots popped
out of the ground--

a clue that this soil
acted like a liquid

during the earthquake.

That's what we call
liquefaction.

I remember when I was 13.

I know what these kids
are going through.

The emotional aftershock
of an earthquake

can last for years.

This is why
I became an engineer.

After leaving Nepal,

Menzer went
to San Francisco.

Here, engineers had
a unique challenge--

designing the city's
tallest skyscraper

at a site prone
to liquefaction.

The engineers solved it
from the ground up.

I.“

Menzer's team tours the site,

where engineers sunk
massive concrete columns

all the way down to bedrock

to resist earthquakes.

I.“

Keeping people safe

has always been the heart
and soul of engineering.

I.“

The first emperor of China
faced a problem:

Mongol warriors were invading
from the north.

So the emperor's engineers
began building something

that would preserve
their civilization

for almost 2,000 years.

I.“

The Great Wall grew to be
13,000 miles long...

the largest structure
ever built by humans.

After centuries of erosion
and earthquakes,

much of the wall survives.

Steve Burrows,
an engineer from England,

has come to investigate.

It's really tough
to study the wall

when it stands there
right on a knife edge

on the top of a mountain.

But we have our ways.

This is lidar,

the laser imaging device.

The lidar showed that the most
precisely built parts

are standing well today.

However, miles away, badly
built sections of the wall

are also still standing.

Why?

500 years ago,
the builders added

a secret ingredient
to their mortar:

sticky rice.

Adding sticky rice and lime
to the mortar,

it makes the mortar
more elastic

'cause it allows the wall
to stretch and contract

depending on the temperature.

Sometimes the best solution

is the simplest--

the one staring up at you

from your dinner plate.

In western China,

across the highest bridges
on Earth,

people are moving
from farms to cities.

Shanghai is now the most
populous city in the world--

24 million people.

But there's a problem.

No more space to build.

Where can they all live?

Engineers squeezed
an entire urban district

into one city block...

by going vertical.

They envisioned
China's tallest building,

the Shanghai Tower,

rising 128 floors high

with space
for 16,000 people.

But the taller the structure,

the more it flirts
with Mother Nature.

Each summer,

typhoons blast the city.

The Shanghai Tower would soon

become a huge target.

But the engineers had

some tricks up their sleeve.

By twisting the outer skin
120 degrees,

the wind safely glides
around the tower.

Here, the problem
of population density

has been met.

All thanks to the ingenuity

of a twist.

Wind is an intriguing
challenge

for engineers of all ages.

Menzer makes a game of it.

Okay, this competition
will count as ten points.

And the tallest skyscraper
that resists the wind

will get five extra.

Yay! Excited?

All right.

Now, remember,
planning is important.

Before cutting...

make sure
what you're building.

Building
these paper skyscrapers

teach kids the most
important thing...

engineering is fun.

Oh, it's getting...

Oh, no!

In 1940,

the newly opened Tacoma
Narrows Bridge, near Seattle,

earned the nickname
Galloping Gertie.

A moderate wind gusting
to 40 miles an hour

made the bridge bounce...

resulting in collapse.

Fortunately,
no one was killed.

Engineers learn
from catastrophes.

New insights about the impact
of wind on suspension bridges

have led to better designs.

Near Menzer's home
in Seattle,

two safer bridges have
replaced Galloping Gertie.

A large bridge
can connect people.

And so can a small one.

I.“

After graduating
from college,

a young bridge engineer
had a choice to make--

accept a high-paying job

or follow her heart.

Today, Avery Bang

leads a team
of passionate engineers

building foot bridges
in poor countries.

In Haiti,

I worked with kids
whose village was isolated.

Just across river
was the only school.

And they could see it,

it was right there,

but they just couldn't
get to it.

Over the past decade,

50 people have drowned
trying to cross this river.

A man who grew up
by the river,

Fritz Touissand,
offered to help.

He had a very personal stake
in this bridge.

Three years ago,

when our youngest girl
needed medicine,

Mathilde, my wife, headed off

to the clinic
across the river.

The river was
very high that day.

Now I have eight children

to raise on my own.

To get to school,

my kids cross the river

right where
their mother drowned.

Mathilde was everything
to them.

They needed a bridge.

At least, it's going to be
a really big bridge.

Our mantra

is "Keep it simple."

With this new hinge
design Avery came up with,

the crew can raise
tall towers,

using nothing but ropes.

...erected from
horizontal to vertical.

Right. Okay.

A young Haitian engineer
named Junior Pierre Louis

has joined the team.

Working with local
engineers like Junior

has a ripple effect.

Today, we're building
one bridge.

Tomorrow, they may build
ten more on their own.

Avery's decision
to follow her heart

has had a huge impact.

Her team of engineers
has volunteered

to build nearly 200 bridges

where they're needed most.

Similar engineering groups

have built thousands more
worldwide.

Every waterway
challenges engineers.

For centuries, trains could
climb Scotland's rugged hills,

but boats?

It once took an entire day

fer a beat to be raised here,

using 11 cumbersome locks.

But then, a team
of visionary engineers

reinvented the wheel--

The Falkirk Wheel.

The arm with the heavier boat

carries less water,

so the wheel always remains
perfectly balanced.

It uses just a wee bit
of electricity.

I.“

I.“

Falkirk is frugal
with electricity.

But renewable energy

holds an even brighter future.

From their small town
in Mississippi,

these high school students

will take the solar car
they built themselves

and compete in
the Solar Challenge.

Some of the kids have never
been to the next county,

much less Australia.

I.“

My name's Ajay Patel.

I'm in the tenth grade

and this is my second year
on the solar car team.

I like the hands-on part,

where you can actually,
like, drill

and use our brains more

and solve problems.

In the Solar Challenge,

the world's top
university teams

will race 1,600 miles

on solar power alone.

All the cars are kind
of strange and elegant.

They're really extreme
and expensive.

A-All of 'em except for one.

I.“

It's
seriously hot inside the car.

120 degrees Fahrenheit.

It's not moving.

Our new lithium batteries

aren't holding a charge.

By tilting the solar panels
towards the sun,

we were able to squeeze
just a bit more power

out of the batteries.

Just enough to keep going.

And we were proud
to cross the finish line.

Even if we were the last ones.

Solar energy
can power a single car

or an entire city.

The world's largest
solar facility,

the lvanpah Solar Electric
Generating System,

reduces C02 emissions
by over 1,000 tons every day.

Hundreds of thousands
of mirrors

slowly pivot
to keep the hot spot

focused on the boiler
at the top.

Water inside turns to steam
and drives turbines,

which produce electricity
for our cities,

like Phoenix, Arizona...

where Angelica Hernandez
is an engineer

working on renewable energy.

I feel like
I've really got it all.

You know, I have
an amazing husband,

I have a super cute baby

and a job
as an engineer, which...

which is one of my dreams.

But, you know,
I didn't start out that way.

I grew up
on the poor side of town.

My mom worked
really, really hard

just m get by-

Then I went
to Carl Hayden High School,

where I met an amazing,
inspiring teacher

who changed my life:

Fredi Lajvardi.

So I see one way
you could solve this.

You could stop
your catapult...

l joined his
after-school robotics class

and the problems
weren't easy to solve,

but Fredi always knew
how to make it fun.

That will leave you
with a higher trajectory...

You're doing a good job.

I.“

The kids were just
having so much fun.

They were learning so much.

They didn't even realize
that they were learning

and that was the best part.

Good catch!

Awesome.

They heard about

a national underwater
robotics competition

in Santa Barbara, California.

And, on a whim,

decided to enter.

Heads up!

We didn't have much funding.

But if you can't be expensive,

be clever.

So we used cheap
landscaping pipe.

In Robotics Club,
Fredi taught us a system:

to find the problem, come up
with different solutions

and pick the best one.

But the one problem
we couldn't solve

was the smell
of the pipe glue.

It just stunk.

So we named our robot Stinky.

- It's working, yeah.
- Yes.

Stinky was a bunch of pipe

with a little bit of CPU

and a whole lot of cables.

Six months and $800 later,

Stinky was ready to go.

Here, guys,
let's, uh, hurry up

and get Stinky in here.

Sadly, Angelica
had work commitments,

and had to miss the trip.

I was really
disappointed, but, you know,

I said my good-byes
and off they went.

I.“

The team arrived
in Santa Barbara

the day before the competition.

Some of the best engineering
programs in the country

compete, like MIT, the champs
from the year before.

We were going with the mindset

that we were going
mainly as observers.

And if we beat
just one college,

that would be phenomenal.

When we arrived there, I mean,

we looked like the carnival
had arrived.

I.“

Just a raggedy robot.

Looked like we'd just
pieced together

everything from a junkyard.

That's MIT.

The other robots

were like pieces
of underwater jewelry.

They were chrome.

There was stainless steel.

There were manufactured
plastics.

I.“

These high school kids

wanted to quickly test Stinky
before anyone noticed them.

I.“

The robot was going left

when they wanted it
to go right.

It wouldn't go up
when they wanted it to go up.

We had to figure out
what was going on.

Fredi has always told
his students

when you get in a jam,
start asking smart questions.

We had a small leak
but no clue where it was.

If we can't find
the leak, what can we do?

And then Lorenzo
asked everybody,

"Aren't tampons
really absorbent?"

This was a do-or-die
kind of situation.

- I got 'em!
- Yeah! -Yes!

It wasn't about
building a robot.

It was about learning
haw to learn for yourself.

The boys arrived
at the competition exhausted,

without a chance
to test Stinky.

Carl Hayden High School,

- you have one minute.
- Let's go, guys!

Do it! You can do it!

We had no idea
if the solution would work.

Thanks to a wild
idea, Stinky was working again.

The boys had 30 minutes
to complete ten tasks.

The college teams had a laser
to measure distances.

Carl Hayden
couldn't afford one.

They used
a tape measure instead.

The hardest task

was to sample a fluid
from a barrel...

with a tube.

Most of the teams
didn't even attempt it.

When we went straight to it,

it just-just fell into it,

like it was meant to be
or something.

At the awards banquet,

they heard something
that surprised everyone.

And second place goes to...

...Massachusetts Institute
of Technology!

MIT got second place.

I was thinking, "Who's first?

"Oh, man, who's-- who beat MIT?

This is, this is
gonna be awesome."

First place goes to...

Carl Hayden High School
from Phoenix, Arizona!

Oh!

It was almost disbelief.

Is this a dream
or is this for real?

I don't remember
walking to the stage,

because, you know,
I was just floating, I think.

What started out
as a crazy idea

turned into something
so much more.

Today, that high school
robotics club

has grown exponentially,

largely thanks to Fredi.

Knowing that
somebody believes in you,

even though you don't
believe in yourself,

even though you doubt
that you could do something,

um, I think, you know, if you
could find that in somebody,

it's just... it's a blessing.

It was because of him
that Angelica went to Stanford.

Now my husband Juan and I

are both engineers in Phoenix.

And, I mean, you never know.

Maybe my daughter
will be one, too.

And any chance I get,
I like to help

my favorite teacher
inspire future engineers.

...the same thing
with this one.

It's not doing it,
because it's a triangle.

It's very solid.
It doesn't change shape.

So now we want you
to come up with different ways

to make the bridge stronger--

so you see the truck
in front of you--

so it can make it
across the bridge.

- You guys want to try that?
- Yeah!

- All right. Let's try it.
- Hey, let's do it.

Well, I think they need
to try to have more triangles.

There's barely any
support going along the bottom.

Yeah, I think
they should put a sign

and say "no trucks allowed."

The screw's not stable, period,
because it fell apart.

- The whole bridge.
-lt's not stable at all.

We have to remind ourselves
about budget cost.

Yeah, but how about we cross
that bridge when we come to it?

Because I think...

Young minds find new paths.

It was not physics alone
that led to

the Millau Bridge in France--
it was art.

That one! -PEHLIVAN:
That one over there, right?

- And what are the triangles
for? -

Young minds
will shape our future.

- It provides, uh, stability,
right? -Yeah.

Some young engineers
have a bold dream

to revolutionize
transportation.

It's called Hyperloop.

If they succeed,
they'll allow us

to travel 700 miles per hour.

I.“

That's from L.A. to
San Francisco in 30 minutes.

By the end of the century,
90% of us will live in cities,

an exciting challenge
for engineers.

I.“

The bigger cities get,

the smarter
they'll need to become.

This new transportation hub

in San Francisco will feature
a network of wireless sensors.

This will make it safer,

more energy-efficient,

and smarter.

I.“

The more urban we become,

the more we need trees,
gardens,

and places to play.

The word "engineer"
means "ingenious."

I love being an engineer.

I create things from nothing.

From blank sheets of paper,
I can change cities.

I can change the future.

The joy
of engineering the future

belongs to the young.

What better time
to start dreaming big.

I.“
