Oh, my God. Oh, my God.

Oh, my God. What am I doing?

One of the most complex systems ever created

was the pattern of detonations inside the atomic bomb

that began the chain reaction.

The scientist who created it, a physicist called John von Neumann,

said that there was only one thing as complex...

..it was the world's climate.

Like the bomb, it was a mass of different forces

moving around a central globe.

Von Neumann then used an early computer

to build a model that simulated the world's climate system.

His aim was to use it to predict and manipulate the weather

as a weapon with which to attack the Soviet Union.

But what he began had another consequence.

In 1961, a scientist called Edward Lorenz

made a mistake which revealed something that astonished him.

Lorenz had built his own computer model of the world's climate.

Then, one day, he ran a programme that he had run many times before,

but missed out one tiny piece of data -

a change at the fourth decimal point.

For 30 days, everything went as before,

but then, suddenly, the computer began to predict weather conditions

never seen before on the planet.

Other scientists said that his model was at fault.

But Lorenz ran it again and again, with tiny variations,

and each time, it led to different, often very strange futures.

He began to wonder whether the world's climate

was not the stable, self-correcting system

that other scientists believed...

..that it was unstable,

and that one tiny change somewhere in the world

could tip the whole system from one state into another.

In America, in the 1960s,

there was a man who was convinced that there was something frightening

hidden under the surface of the new modern suburbs.

Behind what looked like a confident individualism

that was rising up throughout America,

there were really hidden fears eating away at people from inside.

Oh, these are gorgeous!

Look! Salt and pepper.

There were feelings of anxiety, loneliness and emptiness.

And he was convinced he could make a lot of money out of these feelings.

He was called Arthur Sackler.

Sackler had trained as a psychiatrist

but in the 1950s

had turned to advertising drugs and medicines to doctors.

And more and more of the doctors he talked with

told him about people from the suburbs

coming to them with vague feelings of anxiety and fear...

..something the doctors didn't know how to deal with.

And in 1963, the company Hoffman LaRoche

hired Sackler to promote a new drug called Valium.

He offered it to the doctors as an extraordinary new way

to treat these inner anxieties,

and he said it wasn't dangerous or addictive.

Valium became an amazing success.

By 1971, it was the most widely prescribed medication

in the western world.

Hoffman's plant in New Jersey turned out 30 million pills in 15 hours -

enough to satisfy global consumption for just five days.

Valium had touched on something inside human beings,

but nobody knew what it was.

The new wave of feminists pointed out that far more women than men

were taking Valium.

They said the drug was being used to blot out the feeling

that millions of women were having

that there was something badly wrong with their lives.

That when they did what they were supposed to do,

it didn't bring the happiness they had been promised.

And I thought to myself, well, I...

There's got to be a better way for me,

and I went about it in the way that I wanted to.

I did what I wanted, regardless of what society was saying.

And then, it all kind of caved in on me.

And I just figured, well, you know, what's the use?

And so I ended up in the state hospital.

But now that I'm on the road back, I found if I...

I don't see there is any solution,

because if I act the way society tells me to act,

and do abide by the rules, my life is fine and everybody's happy.

But Arthur Sackler suspected

that the drug had touched on something much deeper,

that the women who spent their days alone in their new suburban homes

were in a kind of laboratory of the future.

They had discovered before anyone else

the underlying weakness with the new individualism -

that you were free, but you were alone.

Women told researchers, "I feel empty somehow,"

or, "I feel as if I don't exist."

And Sackler knew

more and more men were also beginning to take the drug.

The women had just got there first.

PLUCKS MELODY

SINGS TRADITIONAL SONG

The Dream Of The Red Chamber

is the most famous novel in China's history.

It was written 250 years before in the 18th century.

It tells the story of the rise and fall of two powerful families.

As their power declines,

the characters begin to find that the line between reality

and a dream world gets blurred.

They slip back and forth between the two.

DISCORDANT MUSIC

Jiang Qing, the wife of Mao Zedong,

had always been fascinated by The Dream Of The Red Chamber...

..because it seemed to show that it is the power of a ruling class

that shapes the very nature of reality itself.

And it was that idea that had driven her in the Cultural Revolution.

She had wanted to create a mass force

powerful enough to change

the very way millions of Chinese people saw the world.

But suddenly, Mao Zedong had turned on her.

He brutally dismissed all her ideas

and she began to realise that maybe he had been using her.

That Mao had used the mass frenzy that she had created

simply as a way of getting rid of his enemies.

It meant that everything that she had created -

the epic operas and ballets,

that promised a new kind of reality in the future -

had just been flimsy illusions

to disguise what had really been a brutal struggle for power.

And now, Mao had sent the Red Guards,

who had been the source of her power,

off to the distant deserts and mountains.

Jiang Qing was increasingly alone, and frightened,

because Mao was turning on all those who had helped him

in the Cultural Revolution.

He tricked the head of the People's Army, Lin Biao,

into plotting a coup.

Mao sent troops to arrest Lin,

but he and his family managed to escape on a plane.

But the plane ran out of fuel

and crashed in the desolate mountains of Mongolia.

Jiang Qing was terrified that she would be next.

She mounted anti-aircraft guns

on the roof of her house in the party compound.

She ate meals at random times to avoid being poisoned.

And she suspected the nurse who gave her sleeping pills

of being an assassin.

Jiang Qing's own sense of reality was beginning to dissolve.

But she also realised that, with Lin Biao destroyed,

she now had a much greater chance of taking power when Mao died.

In 1967, the Russians launched a space flight

to celebrate the 50th anniversary of the Revolution.

It was called Soyuz 1.

Everything seemed to be going normally

but the astronaut knew that something terrible

was likely to happen.

He was called Vladimir Komarov.

Komarov's best friend was the Soviet hero Yuri Gagarin,

who had made the first human flight into space.

As they prepared for the launch,

Gagarin had inspected Komarov's spacecraft.

He discovered hundreds of faults in its construction.

He told Komarov what he had found,

that the spacecraft was a deathtrap.

Gagarin tried to get the launch stopped,

but the Communist Party leaders refused.

"The launch had to go ahead," they said,

"to celebrate the anniversary of the revolution."

Komarov went, but on one condition.

If he died, his body should be displayed in an open coffin.

Things went wrong from the start.

The spacecraft lost power.

Komarov tried to manually guide it back to Earth.

But then the parachutes failed to open.
