01x10 - A Tale of Two Atoms

Post by bunniefuu »

TYSON: The kingdom of

matter stores it treasures

on my many levels.

Until recently, we thought

there was only one.

We had no idea

there were others.

When we strike a match, a

chemical reaction liberates

energy stored in the molecules.

Old chemical bonds break

and new ones are forged.

Now, the adjacent molecules

begin to move faster and the

temperature increases.

Soon, the process

becomes self-propagated,

a kind of chain reaction.

The energy represented

by a flame has been locked,

perhaps for many years, in

chemical bonds between atoms.

Mediated by the electrons

that revolved around their core.

When we make a fire,

we release this hidden

chemical energy.

But there is a deeper

level of matter that

houses another kind of energy.

Inside the heart of

the atom, its nucleus.

This hidden treasure was

forged billions of years ago

in distant stellar furnaces.

Long before Earth was formed.

It's what powers the stars.

Wresting this

knowledge from nature

is a cosmic rite of passage.

The beings of any possible

world clever enough to travel

this deep into nature's

labyrinth better take care.

The secret of starlight

is nothing to fool with.

Like fire, it can bring a

civilization to life and it

can burn it to the ground.

What is an atom?

What are they made of?

How are they joined together?

How could something

as small as an atom

contain so much power?

Where do atoms come from?

The same place we do.

When we seek

the origin of atoms,

we are searching for

our own beginnings.

This quest takes us to the

depths of space and time.

I want to tell you

a tale of two atoms.

Come with me.

Long ago, before

there was an Earth,

there was a wisp

of cold thin gas.

It was made of

the simplest atoms.

And they were gravitationally

attracted to one another.

So, the cloud grew.

The atoms contained small,

but heavy particles

in their nuclei.

The hydrogen had protons,

the helium had neutrons as well.

They both had a

skittering veil of electrons

in orbit around them.

The atoms in the interior of

the cloud moved ever faster

as gravity pulled them

ever closer together.

Until the whole thing

collapsed in on itself.

This collapse raised

the temperature so high,

that the cloud became

a natural fusion reactor.

In other words, a star.

Atoms operating according

to the laws of physics met

and fused in the

unbroken darkness.

And then there was light.

In this froth of

elementary particles,

the nucleus of one of the atoms,

a helium atom, was formed.

After billions of years,

the star is now elderly.

Having converted all of its

available hydrogen fuel to helium.

Now that it's time

for the star to die,

it resumes the turning

inward of its infancy.

Can you find our helium atom?

It joined with two others to

become one of our heroes,

a carbon atom.

That's what in

the hearts of stars.

Soon, our carbon atom

will tumble out of this

red giant star into the

interstellar ocean of space.

We've tinted this atom

blue so you can find it

in the vastness.

Meanwhile, in another

part of the galaxy.

Similar processes were

unfolding as stars were

born and died.

The other atom of our

tale was formed in the heart

of this dying star.

In the catastrophic

process of going supernova,

226 protons and neutrons

became fused to a carbon atom.

Turning it into a uranium atom.

We've tinted our

other hero atom red,

so that you could

follow it on its odyssey

through space and time.

As chance would have it,

after wandering the

vast Milky Way galaxy,

our two atoms both

happened on the fiery birth

of a small solar system.

Ours.

Our carbon atom has traveled far

to become part of a small planet.

After billions of years, it

joined an extremely complex

molecule, which has the

peculiar property of a making

virtually identical

copies of itself.

The carbon atom plays its

tiny role in the origin of life.

Through all its incarnations,

our carbon atom has

had no self-awareness.

No free will.

It is merely an extremely minor

cog in some vast cosmic machinery,

working in accord

with the laws of nature.

And that other atom?

The uranium atom

made in the supernova?

What has become of it?

Our world was born in fire.

And this tiny atom

was drawn to it.

Maybe it rode the expl*sive

wave of a supernova.

Or perhaps, it was attracted

by the gravity of our sun and

pulled down deeper and

deeper into the interior,

which was even more of a hell.

The Earth's surface soon cooled,

but the interior

remained molten.

The magma slowly circulating

and our uranium atom found

itself carried over the

ages, from the deep interior,

back all the way

up to the surface.

Despite the high temperatures

and pressures deep within the

Earth, our atom's integrity

was never threatened.

Atoms are small,

old, hard and durable.

Everything is made

of atoms, including us.

But until the last years

of the 19th Century,

we didn't know about the

frenzied activity inside the atom.

And this is where our two

atoms from opposite ends of

the Milky Way

galaxy finally met.

It happened in Paris.

♪♪

TYSON: Our carbon atom

became part of the retina of one of

the world's greatest scientists.

This was just a few years

after the discovery of x-rays.

Marie Curie and her

husband and research partner,

Pierre, wanted to know how

a piece of matter could make it

possible to see through

skin and even walls.

The knowledge that there were

rare places in the world where

rocks, rich in uranium,

possess these strange

properties inspired Marie

on her scientific quest.

The dull brown ore, still

mixed with pine needles,

came from the part of Eastern

Europe that is now the Czech Republic.

But this material was very rare.

And even to distill a

tiny amount of it required

the most lengthy and

labor intensive efforts.

She was later to write,

"we lived in our single

occupation, as in a dream."

[THUNDER, RAINING]

They worked under the

worst possible conditions to

purify the ore into a

mineral called pitchblende,

which was 50 to 80% uranium.

This was quite an achievement,

but Marie and Pierre were

hunting for something

far more rare.

It took them three years

to process tons of ore.

To isolate a mere tenth of a gram

of a substance she named radium.

Marie and Pierre had discovered

a completely new element.

The Curies showed that

the radium was entirely

unaffected by

extreme temperatures.

That was strange.

Most things subjected to

such intense heat would

change drastically.

And, there was something else.

It spontaneously emitted energy.

Not through chemical reactions,

but through some

unknown mechanism.

Marie Curie called this new

phenomenon radioactivity.

She and Pierre calculated

the energy that spontaneously

flowed from a lump of radium

would be much greater than

burning the same amount of coal.

Radioactivity, to

their astonishment,

was millions of times more

potent than chemical energy.

The difference between

liberating the energy that

resides in molecules

and the far greater power

stored deeper down.

Between Marie, Pierre,

little Irene and the man

she would later marry,

the family would win five

Nobel prizes in science.

(fire crackling)

The bottles, tubes and

flasks of pitchblende that

they had refined, left a

residue of radium particles.

They were so potent, that

they lit up the lab at night.

As Marie wrote years later,

"they were like Earthly stars,

these glowing tubes in

that poor rough shack."

Marie leapt to the

correct conclusion that the

luminescence was due to

something happening inside

the nuclei of radioactive atoms.

For thousands of years, it had

been thought that atoms were

the smallest unit of matter.

Curie's earthly stars were

evidence that within the atom

was a possible world

where even smaller

particles were interacting.

100 years after

this magical night,

Marie Curie's cookbooks

still glowed with the exquisite

radioactivity she

had discovered.

But it took a little time for

the darker implications of

this deeper understanding of

nature to dawn in the mind of

a visionary named H.G. Wells.

A writer, who was a

genius at turning the

new revelations of

science into stories

that captivated the world.

And foreseeing as no one

else, their gravest consequences.

TYSON: The writer H.G. Wells,

who first imagined time

machines and alien invasions

had a nightmare of a

future world where atoms

were weaponized.

In his book called The

World Set Free written in 1913,

he coined the

phrase atomic bombs.

And loosed them on

helpless civilian populations.

He set his vision of a nuclear

w*r between England and

Germany in the impossibly

distant future of the 1950's.

♪♪

(expl*si*n)

In 1933, the

Hungarian physicist,

Leo Szilard, was contemplating

becoming a biologist.

(knocking)

MAID: Dr. Szilard?

Are you quite

all right in there?

TYSON: He read Wells'

novel and it started him thinking.

(chatter)

TYSON: Szilard knew that

atoms are made of protons and

neutrons on the inside.

And a skittering veil of

electrons on the outside.

Suddenly, awaiting for

the light to change at this

intersection in London, he

was struck by the thought,

if he could find a

sufficiently large amount of

an element that would emit two

neutrons when it absorbed one,

it would sustain a

nuclear chain reaction.

Two would produce four,

four would produce eight

and so forth.

Until enormous amounts of

energy in the nucleus itself

could be liberated.

Not a chemical reaction,

but a nuclear one.

(gasping)

(air raid alarm)

(expl*si*n)

(honking)

(grunts)

TYSON: This was the

moment our world changed.

Leo Szilard also knew the

power of exponentials and

if a neutron chain reaction

could be triggered down there

in world of the atom's nucleus,

then something like Wells'

imaginary atomic b*mb

might be possible.

He shuddered at the thought

of this destructive capability.

It was just the latest

development on a continuum

of violence that

began long long before.

50,000 years ago,

all humans were roving

bands of hunter-gatherers.

They communicated

over limited areas by

calling to one another.

That is, at the speed of sound.

Around 750 miles per hour.

But over longer distances,

they could communicate only

as fast as they could run.

Around 12,000 years ago,

about the same time as the

invention of agriculture,

they developed the power to

k*ll at a longer distance.

The k*ll radius expanded

to the arc of an arrow

launched by a bow.

And they could k*ll one

person with a single arrow.

Our ancestors were not

particularly warlike because

there was so few people and

so much room back then that

moving on was

preferable to armed conflict.

Their weapons were used

almost entirely for hunting.

Their identification

horizon was likely small.

Only with the other

members of their band of

50 or 100 people.

But their time horizon

took a giant leap.

They worked long and hard

planting crops in the here and

now, so several months

later, they could harvest them.

They postponed present

gratification for later advantage.

They began to

plan for the future.

By about 2,500 years ago,

there was a new kind of w*r.

The conquered territories

of Alexander stretched from

Macedonia to the Indus Valley.

There were now many on planet

Earth who owed allegiance to

groups composed of millions.

Over long distances,

maximum speed of both

communication and transportation

was the speed of

the sail and the horse.

Archidamus III, King of Sparta,

was famed for his

unflinching courage.

He relished taking part in hand

to hand combat with the enemy.

It is said that when he first

saw a projectile hurled by a

Balista, he cried

out in anguish.

"Oh Hercules! The

valor of man is lost!"

(screaming)

(groaning)

Both the k*ll range

and the k*ll ratio

had increased exponentially.

Now, ten corpses lay

where one would have been.

And the soldier who released

the lever on the siege engine

never even saw their faces.

He remained far removed from

the carnage on the other side

of the city wall.

Today, the maximum speed

of transportation is the escape

velocity from Earth.

25,000 miles per hour.

The speed of communication

is the speed of light.

The identification horizons

have also expanded enormously.

For some, it's

a billion or more.

For others, it's

our whole species.

And for a few,

it's all living things.

The k*ll radius, in the

worst case scenario,

is now our global civilization.

How did we get here?

It was the result of a deadly

embrace between science and state.

And there was one scientist

for whom no amount of

destructive power was enough.

(distant expl*si*n)

(air raid alarm)

TYSON: It's hard to pinpoint

the precise moment when the

first nuclear w*r began.

Some might trace it all the

way back to that arrow sailing

over the treetops.

Others might say it

started much later,

with three messages.

In 1939 on Adolf

Hitler's birthday,

one of his brightest

young scientists,

Paul Harteck, had a special

gift in mind for his Führer.

Harteck wrote a letter

to the n*zi w*r office,

he wished to inform them

that the latest developments in

nuclear physics would make it

possible to produce an expl*sive

exponentially more powerful

than conventional weapons.

He was trying to give an

atomic b*mb to Adolf Hitler.

But Hitler would never get

his hands on a nuclear weapon,

he had m*rder*d, imprisoned

or exiled many of the great

physicists in his territories.

Those who happened

to be Jews or liberals and

many who were both.

Exactly a month

before the w*r began,

Leo Szilard made a pilgrimage

to the house Albert Einstein

was renting on Long Island.

The physicist who usually

chauffeured Leo Szilard on

trips out of Manhattan was

unavailable that August day in 1939.

So, Szilard enlisted the services

of a fellow Hungarian emigrate,

a young scientist

named Edward Teller.

Persecution in Budapest

sent him and his family to

take refuge in Munich,

where he lost his right

foot in a traffic accident.

In the early 1930s, Teller

and his family were forced

to flee once again.

Just as Harteck felt it

his duty to inform Hitler.

Szilard wanted President

Franklin Roosevelt to know

the awesome power

of such a weapon.

There was no scientist on

Earth whose prestige and

influence was

comparable to Einstein's.

Einstein's nightmare

was imagining Hitler with a

nuclear weapon at his disposal.

But what would be the

long-term consequences of

this dangerous new knowledge?

Which, once unleashed,

could never be taken back.

Einstein would take

no role in the U.S.

effort to build the atomic b*mb,

which became known as

"The Manhattan Project."

But he did alert the President

to the potential use of

atomic nuclei in warfare.

After the w*r was over, he

told a reporter that if he had

known the Germans would

fail in developing in an atomic

b*mb, he never would

have signed the letter.

But Edward Teller had

no such ambivalence.

He couldn't wait to get started

on weaponizing the atom.

The Russian physicist, G.N. Flyorov

had tried for years to alert his leader,

Joseph Stalin, to the possible

military applications of a

nuclear chain reaction.

But the Soviet Union was

under siege by the Germans.

And an atom b*mb project was

likely to take years to complete.

With their backs

against the wall,

it seemed too impractical

to even think about.

(coughing)

In 1942, Flyorov had

published a scientific paper

on nuclear physics.

Now, he was excited to see

what the eminent physicists

in Europe and the United

States had to say about it.

Flyorov was puzzled.

None of the physicists of

the International Scientific

Community thought his

paper worthy of comment.

At first, he was hurt, but

then he realized what was

really happening.

American and German scientific

journals were being scrubbed

of any nuclear physics

papers as both nations secretly

worked on building the b*mb.

It was this absence

of published data,

the dogs that did not

bark, that moved Flyorov to

re-double his efforts to

convince Stalin to start his

own nuclear weapons program.

In all three cases,

it was the scientists,

not the generals

or the arms dealers,

who informed their leaders

that a huge increase in

k*ll ratio was possible.

The U.S. Department of w*r

chose the remote location

of Los Alamos, New Mexico

as the headquarters for the

atomic b*mb research project.

It had been recommended

by the project's director,

physicist J. Robert Oppenheimer,

who had recuperated there

from an illness as a teenager.

But for Edward Teller, an

atomic b*mb wasn't big enough.

He dreamed of

even greater lethality.

A weapon in which the atomic

b*mb was nothing more than a

match to light a

fuse to the nucleus.

A thermal nuclear weapon.

What Teller affectionately

called, the super.

If Edward Teller had a polar

opposite in the scientific community,

it would have been

Joseph Rotblat.

Rotblat was born in

Warsaw to a wealthy family,

who like Teller's,

had lost everything.

In the summer of 1939,

just before the Nazis invaded,

he was invited to England

to take a research position at

the University of Liverpool.

At the last minute

before his departure,

his beloved wife, Tola had

an emergency appendectomy.

She was forced to remain

behind until she was

well enough to travel.

Tola insisted that Joseph go on

ahead to prepare their new home.

It would just be a matter

of weeks, she told him.

The challenge, was to

find a chemical fuse that

would light the

nuclear chain reaction,

first imagined by

Leo Szilard in London.

The scientists and engineers

told themselves that they

would be averting a grave

danger by building a b*mb

of unprecedented

destructive power.

Their government

could be trusted.

They would never use

such a weapon in an act of

aggression, not like

those other governments.

These atomic scientists

were the first to see

building nuclear weapons

as a deterrent to using them.

The fear of Hitler with an

atomic b*mb was the driving

rationale for the

Manhattan Project.

And yet, when Germany

surrendered and Hitler was no more,

of the thousands of scientists

who worked on the b*mb,

only one resigned.

It was Joe Rotblat.

In the years that followed,

whenever he was asked about

his decision, he always

rejected any suggestion that

he had done so out

of moral superiority.

He would just smile and

say, the truth was that he

desperately missed his wife,

who had been prevented from

leaving Warsaw and lost to

him in the chaos of the w*r.

With its end in Europe

came his chance to

go and search for her.

But, he never found her.

Except as a name

on a list of the dead.

Tola had perished

in the Holocaust.

Exterminated at the

Belzec concentration camp.

Although he lived

another 60 years,

Rotblat never remarried.

(expl*si*n)

Of the three nations that

pursued wartime research

into building the b*mb,

only the U.S. succeeded

before the w*r's end.

And historians believe that

was because America had

taken in so many immigrants.

Of the leading figures

in the Manhattan Project,

only two were native born.

And only one got

his PhD in the U.S.

Atomic bombs were dropped

on the Japanese cities of

Hiroshima and Nagasaki,

ending the second World w*r.

Two months later, President

Truman invited Oppenheimer

for congratulations

in the Oval Office.

But to Truman's dismay,

Oppenheimer was in

no mood to celebrate.

OPPENHEIMER: Mr. President, I

feel like I have blood on my hands.

TRUMAN: Don't be a fool.

If anyone has blood

on their hands, it's me.

And it doesn't bother me at all.

OPPENHEIMER: How long

do you think it will be before the

Russians get the b*mb?

TRUMAN: Never!

Don't you ever let that

cry baby scientist anywhere

near me again, do you hear?

TYSON: Less than

four years later,

the Russians exploded

their own atomic b*mb.

And shortly after, both

nations went on to create

supers: thermonuclear

hydrogen bombs.

The nuclear arms race begun

by those three letters from

scientists was off

to a terrifying start.

After the w*r, Teller's dreams

of greater and greater k*lling

power were to come true.

The early 1950s, when the

Communist witch hunts began

in the United States, he

was perfectly happy to hint

that Robert Oppenheimer,

his former boss,

who had brilliantly run

the Manhattan Project,

should be stripped of

his security clearance,

thereby ruining

Oppenheimer's career.

Despite dramatic reductions

in nuclear arsenals,

the specter of nuclear

w*r haunts us still.

How can we sleep so soundly

in the shadow of a

smoking volcano?

In another time, there

were others who faced a

grave danger as if

immobilized in a dream.

♪♪

TYSON: Let me tell you a story.

Two men walk into a bar.

♪♪

And they got into a fight.

(glass breaking)

(grunting)

(grunting)

(gasps)

SOLDIERS: Allez!

(grunts)

TYSON: Louis-Auguste Cyparis

was arrested and taken to the

Saint Pierre Prison, where

he was locked in the dungeon.

(grunting)

TYSON: This all happened

on the French colonial island of

Martinique in the

Caribbean in 1902.

In the midst of an

election campaign.

On this April morning,

Fernan Cleric stepped outside

to admire the view.

He was master

of all he surveyed.

The factories that turned

the island's trees into furniture.

And the fields of

sugar cane and coffee.

That's strange.

Why would there be frost on

such a sunny warm morning?

But it wasn't frost, it

was ash from the volcano,

Mount Pelée.

(eruption)

(gasps)

TYSON: When the

ash began to fall,

Claire Apprentice, wife

of the American Council

considered going

home to Massachusetts.

No, but that was

out of the question.

There was the gala she

planned for the following week,

postponing it was unthinkable.

And there were many who were

too poor to leave their meager

possessions and flee

the city of Saint Pierre for a

safer part of the island.

Others, with the means to do so,

departed on boats.

Mayor Fouché worked

late into the evening,

drafting detailed plans for the

Ascension Day Banquet and Ball.

Meanwhile, below

Servants cleaned ash

from the banquet hall

in preparation for the event.

The closest thing to a scientist

on the island of Martinique

was an elementary school

teacher named Gaston Landes.

Landes actually made

a pilgrimage to the newly

awakened volcanic crater

and shared his observations of

heightened activity

in the newspaper.

But Landes was more

concerned about his

forthcoming trip to Paris.

He was to display samples

of the island's plant life along

with the lecture he

had been asked to give.

But, with the ash

falling at this rate,

his specimens

would all be ruined.

Mayor Fouché mustered enough

resolve to create a new poster.

"Fellow citizens,

be not afraid."

No lava flows could reach

the city in the near future.

We have seven kilometers

between us and the volcano.

The amount of lava would

have to be impossibly huge

to cross the two immense

valleys and the swamp

"between us and Mount Peleé."

(coughing)

In the early hours of May 7th,

the people Saint Pierre awoke

to thundering seismic tremors

and volcanic lightning near

the mouth of the hellish volcano.

Now, mass panic began to spread.

Troops were dispatched

to try and calm the public.

And then

Just before the dawn

of Thursday morning.

May 8th.

The volcano became utterly calm.

The air was cool and fresh.

And the sea like glass.

(eruption)

(screaming)

TYSON: When Mount

Pelée erupted at 8:02 AM on

May 8th, 1902, the expl*si*n

produced a sound so loud

it was heard 500 miles

away, in Venezuela.

The massive pyroclastic flood,

a death cloud of

super-heated gasses,

crossed the valleys

to the city in minutes.

The expl*si*n was the

equivalent of just one

strategic nuclear warhead.

Three days after the eruption,

men from the other

part of the island,

combed the still smoking

streets of Saint Pierre.

To collect the bodies and

burn what the volcano had failed

to consume completely.

(grunting)

(calling)

TYSON: Few have

ever experienced what

Louis-Auguste Cyparis

endured and lived to tell.

When the volcano erupted,

he heard the screams of his

captors briefly before

a terrifying silence.

And then, a fierce heat

came blasting through the

tiny vent in his cell.

He hopped and jumped

around to avoid it,

but was still severely

burned up to his shoulders.

For three days he

suffered in agony with

no other sustenance than the

moisture on the walls of his cell.

His sentence to solitary

confinement in the thick

walled dungeon

had saved his life.

He was one of only

two survivors of the

30,000 citizens of Saint Pierre.

What about us?

Would we know when

to sound the alarm?

Can we see what's coming?

Can we awaken in time?

(buzzing)

TYSON: We're back on the

trail of one of our two atoms.

The uranium atom.

A uranium atom is

inherently unstable.

Sooner or later, it decays.

A particle from its

nucleus breaks away,

transforming the uranium atom

into an entirely

different element.

Thorium.

We're flying through the

crossfire of radioactive decay.

Subatomic particles move

like b*ll*ts through the

fine structure of life.

Shearing electrons

from their molecules.

This is how ionizing

radiation affects living things.

Those chromosomes

never had a chance.

This is why atomic weapons

are so much more dangerous

than conventional ones.

Ionizing radiation is all

around us and even inside us.

At low levels, it

poses no threat.

But at higher levels,

it's a different story.

In the near term, exposure

to lethal levels of radiation can

cause a runaway reaction

of the cell that makes it

multiply exponentially.

Cancer.

But its power to harm can also

echo down the corridors of time.

When the radiation tore

into the chromosomes of the

butterfly, it left a trail of

destruction in its wake that

changed the destiny of the

butterfly's unborn offspring.

A mutation in its genes.

We have a lot in

common with butterflies.

Any change in the DNA

architecture will be copied

over and over again in

succeeding generations.

The damage is passed on.

Vandalizing our future.

We are made of atoms that

were born in stars thousands of

light years away in space

and billions of years ago in time.

The search for our own

origins has carried us

far from our epoch in our world.

We are star-stuff,

deeply connected with

the rest of the universe.

The matter we are made of

was generated in cosmic fire.

And now, we, ambulatory

collections of seven billion

billion billion atoms

intricately assembled over

eons has devised a means

to tap that cosmic fire,

hidden in the heart of matter.

We cannot unlearn

this knowledge.

And tragically, insanity

runs in our family.

The letters that the

scientists wrote to begin

this nightmare were

followed by another.

This one, a letter

to the planet,

stating that this new

understanding of physics

demanded a new way of thinking.

"Shall we choose death because

we cannot forget our quarrels,

we appeal as human

beings to human beings.

Remember your humanity

and forget the rest."

And what of our other atom?

The carbon atom?

It's inside one of you.
