Two months later...
Man releases the destructive power

into the very fabric of matter,
and plunge the world
in the atomic age.
Over the next 20 years,

TRUBULENCES IN EUROPE!
Hitler invaded Austria!
March 13, 1938.
Hitler invaded Austria.
3rd Reich begins to deploy
its military power.
Later that year,
German scientists
discover fission
of the uranium nucleus
What brings the 3rd Reich
a step
the discovery of the secret
of the atomic bomb.
FEAR!
Fear of German research
stimulates activities to
United States and England.
The fear that German scientists
could produce weapons
high destructive power.
In autumn 1939,
Dr. Albert Einstein
wrote his famous letter
President Roosevelt,
explaining the urgency of working
in the fission of uranium.
Roosevelt, a man of action,
responded quickly,
and creates an advisory committee
of uranium.
GERMANY INVADES POLAND!
German forces invaded Poland
dragging European nations
in the second world war.
ING DISTRICT NIEURIE
OF MANHATTAN
A new branch of the Corps of Engineers
was created to oversee the work
on military use of uranium.
Major General L.R. Growe,
the man in charge of the Pentagon,
was appointed head
project.
December 2, 1942, the first reactor
Autonomous chain reaction
has been successfully exploited by Enrico Fermi.
The success of Fermi generates
great efforts
the government
and the private sector,
leading to the creation of huge factories,
for the separation of uranium
in the town of Oakridge, Tennessee,
and for the production of plutonium
Hanford, Washington
on the banks
Columbia River.
Through this effort was forged great
the necessary hardware
to create an atomic bomb.
The first atomic bomb
was built at Los Alamos,
a secret laboratory
New Mexico
When Dr. Oppenheimer J.R.
arrived to take command
he surrounded himself with an incredible range
stars of the scientific world.
Los Alamos was born on design
the bomb and resolution
many theoretical problems.
Many questions remain unanswered, however.
What are the secrets of this new
form of power and destruction?
Knowledge and Information
all aspects of this new weapon
are essential,
and can not be discovered that
by further testing.
I had a good friend, a Hungarian
10 years older than me, Leo Szilard.
He had a very independent-minded
and a large capacity
foreshadow what would happen.
He saw the years ahead
the importance that the explosives
Nuclear would take.
He was a friend of mine, and I helped him.
For example, I took it to
an important interview with Einstein
where Einstein wrote this
famous letter to Roosevelt.
The letter that started it all.
I myself was interested in
Theoretical Physics
atoms, molecular vibrations,
and knowledge of molarity.
I did not want to do.
But then...
Hitler had not only swallowed
half of Poland,
he had also invaded the West.
Two days later, there was
an invitation to a Pan-American Congress
in which Roosevelt, that I had never
seen before, was to speak.
He made a memorable speech,
about how the world is
really in danger because of Hitler.
He said in part, to the point
highlight of the speech:
"You scientists, will be blamed
for the arms to be used"
but I tell you,
"if you do not work on these weapons,
world freedom will be lost."
You know, I felt
Roosevelt spoke to me.
I was there when
The letter was signed
one that stirred up the interest
in nuclear power
He was convinced that
was nuclear
Of the 2,000 scientists who were there,
I felt it spoke to me.
Of course it was not that...
But for this speech
twenty minutes
I made my decision.
I continued to prefer
work in science 'pure',
but this must be done.
Since this must be done
and that I could contribute,
I did,
and I have never regretted
to have done.
The uranium bomb,
called "Little Boy"
had a simple design.
And scientists were convinced
fonctionnerai it without testing.
"Fat Man", or the implosion bomb,
was a more efficient design
which used plutonium
rather than uranium.
In the center of the bomb,
there was a detonator
surrounded by a sphere of plutonium.
This sphere was encapsulated
in a series of lenses highly
explosive placed symmetrically,
creating an implosion
compressing the sphere of plutonium
on itself until it
reaches critical mass.
The explosion brought immediately
temperature to 10 million degrees,
releasing a force of one half
million pounds of pressure
vaporizing the tower and all
desert living within 800m.
The intensity of the light
was sufficient
to cause temporary blindness
an observer at 16 km distance.
With a score of 200 times more potent

the fireball created a crater
about 800 m in diameter.
And melted the desert sand

always contain traces of radioactivity

This puts an end to the war in Europe.

that Germany had not developed
the atomic bomb.
However, the war continued

The uranium bomb,
called "Little Boy"
exploded over Hiroshima
at an altitude of 250 meters.
The altitude to achieve
maximum blast.
Three days later,
the implosion bomb "Fat Man"
exploded over Nagasaki.
In Hiroshima 70,000 people
were killed or missing.
On its 90,000 buildings,
more than 60,000 were demolished.
The implosion bomb dropped on
Nagasaki took the lives of 42,000 people,
and injured 40,000 others.
It destroyed 39% of
buildings in the city.
With a yield of 20 kilotons,
similar to that of Trinity,
this weapon will be considered
as a normal bomb,
and serve as a model for
future nuclear weapons.

But our main objectives
are the warships.
We try to first learn
What types of ships, training

in case we need to cope.
OPERATION CROSSROADS
11 months after the bombing
Hiroshima and Nagasaki,
the operation was conducted Crossroads
on Bikini Atoll
4000km to the west of Hawaii.
The aim of the operation
was to test the effects of weapons
nuclear using two devices
similar in design to those
Trinity and Nagasaki.
Their code names:
"Able" and "Baker".
Able to be launched
from a B-29,
while Baker was detonated
to 30 m below the water surface.
The fleet consisted of target
185 Japanese ships
German and American.
From small amphibious craft
to battleships and aircraft carriers.
The bomb will not start a
chain reaction in water,
converting it all to gas
and to ensure that all vessels,
of all the oceans, fall to the bottom.
It will not explode

and bring down all the water
a hole in
It will not destroy gravity.
I am not an "Atomic Playboy"
as one of my critics called me,
that these bombs would explode
to satisfy my personal whim.
Animals, plants, and similar agents
biological warfare were assembled
to study the effects of heat,
blast and radiation.
The bomb missed its target
of almost 750 meters
The explosion sent five ships,
including two destroyers,

All vessels within 800m
were severely damaged.
But the damage was
far from those caused
by the underwater explosion
that followed, called Baker.

Baker was an underwater explosion
Navy of the same device,
and caused much more damage
the fleet to 70 vessels.
For example, on the USS Saratoga
the shockwave submarine tore
the bottom of the hull of the boat.
Saratoga sank still lies
at the bottom of the sea from Bikini.
I flew several times
the site and on a clear,
if the water is calm,
you can still see the Saratoga.
The area around
the explosion of Baker
had become highly radioactive,
and could not be
approached for some time.
This effect was not expected,
and led to the decision
President Truman
to cancel a third nuclear test
deep called "Charlie."
Here the city of Los Alamos,
to 1500 meters.
The Atomic City .
is a modern city
created by United States
as a research center
and development of nuclear weapons.
We are talking about a region
remote and primitive,
men must leave their homes
laboratories and their States,
for a term which may
reach for months.
Since 1943, when
Los Alamos was founded,
these men left
the continental limits of the United States
to test weapons
they have created.
Two years after
Operation Crossroads,
President Truman authorized
to conduct the operation Sandstone.
While the goal of Crossroads
was to test the effect
nuclear weapons,
Sandstone objective was to test
design new weapons.
Plans for these weapons were
initiated several years earlier
when researchers from Trinity
have developed other models
experimental atomic weapons,
but were not sure of their success.
A joint working group was created
to go back into the peaceful,
and obtain the island of Enewetak,
300 km west of Bikini,
Crossroads which had taken place.
In early November, the first
Construction crews arrived
to remove all the vegetation of the island,
clean the area and dump
tonnes of asphalt for roads.
In six months, the team built
temporary housing
for many scientists and military
necessary for the operation Sandstone.
Perched on steel towers
60 meters high,
the three devices used to Sandstone
employed a new technology
to double the explosive power
of the bomb
using the same amount of
plutonium spent in Nagasaki.
This technology meets the requirements
Department of Defense
create more effective bombs
and increase the capacity of
store nuclear weapons.
Radio controlled tanks,
guided by helicopter
recovered samples
fission near "ground zero",
for measuring the intensity of
neutrons and gamma rays.
Radiochemical analysis
pulverized coral sand
revealed the secrets
the nuclear reaction,
and helped to determine the effectiveness of
bombs of new design.
The results of Sandstone affectrent
the design of future nuclear weapons,
making the components 'Mark-3', used
for the production of Fat Man, obsolete.
Designs 'Mark-4' and 'Mark-5'
led to better performance and a
lighter weight for nuclear weapons.
The division of the laboratory Z
Los Alamos National
moved to the base has Sand,
located in Albuquerque, New Mexico,
near Kirtland Air Force Base.
The main objective of the Sandia Base
was the study and production of nuclear weapons
"Mobile" designed at Los Alamos.
in October 1949,
Western Electric contracted with
The Committee on Atomic Energy,
agreement "no taxes, no profit"
to form the Sandia Corporation
who took control
the basis of Los Alamos.
Sandia has led to techniques

and mass production
nuclear weapons,
to increase the supply of arms
tactical and strategic nation.
After returning from Bikini,
in public statements,
interviews and published articles,
Admiral Blandey
made important recommendations
on atomic bombs.
It is essential that no other nation
takes the ascendancy over the United States
in the development, manufacture and
the use of tactical nuclear weapons.
"TRUMAN SAYS RUSSIAN
HAVE A BOMB"
"THE L legislator TOLD OF SECRETS
AMERICAN FLIGHT AID S S HAVE THE RUSSIANS"
On 29 August 1949, the Russians did
exploded their first atomic bomb.
This event,
which took place five years earlier
than anyone in the west
have been expected,
was largely responsible
a man, Klaus Fuchs.
Fuchs, a physicist at Los Alamos,
spent blueprints
the design of
Trinity to the Russians.
With the emergence of the USSR
as a nuclear rival in 1949,
the United States were convinced
have good reasons
increase their programs
nuclear testing.
It was very expensive and it
involved a lot of logistics
perform operations
in the Pacific.
In this and in January 1951, the United States
inaugurated the test area of?? Nevada,
we now call
"The Nevada Test Site"
which is located approximately 100 km
north of Las Vegas.
Before you can test the
Weapons of Operation Greenhouse,
the operation was performed Ranger
during which five
new types of nuclear weapons
were launched on
new test area.
First explosion to United States
from Trinity.
With the confidence of having
The new weapons in hand,
Operation Greenhouse was
conducted in Spring 1951.
4 launches took place
Greenhouse during the operation.
One of them, "Easy"
a structural test was controlled
by the Ministry of Defence.
A nuclear device of 47
kilotonnes was placed on a tower,
which blew many buildings,
that had been built
to test the survivability
in a nuclear environment.
Test structural effects.
The fourth test of the operation
Greenhouse testing was "Item".
A trial approximately 45.5 kilotonnes
in which tritium was burned
in the center of the nuclear explosion.
And this process, placing the center of tritium
of nuclear weapons is called "Boosting".
We increased the yield
from 20 to 45.5 kilotonnes,
more than double,
through this process.
A very important feature
to increase the storage capacity
nuclear weapons of United States
at that time.
First test of the principle "Boosting"
Another event of Greenhouse
was the event called "George."
George was a huge weapon
of 225 kilotons
which was used to burn
a capsule deuterium.
This was the first experience with weapon
Thermonuclear we conducted.

The three islands that make up
the test site
have been connected by bridges,
constructed to facilitate
the displacement of an island to each other,
and to serve as a platform
for some of the instruments.
On the island "Mike" was the cab,
or the building housing the device.
The device "Mike" was called
the "wet bomb"
because he used
liquid hydrogen isotopes
to create the thermonuclear reaction.
This made the device
very impressive,
it weighed 62 tons which made
impractical as throwing weapon.

THE BATTLEFIELD AREA NUCL
In the spring of 1953,
Commission for Nuclear Energy
and the Department of Defense has made
11 nuclear tests in Nevada
under the code name
"Upshot-Knothole."
The Upshot-Knothole objective was to
test new nuclear weapons,
improve tactics of combat,
and study the needs of defense
civil case of Soviet attack.
The first event, called "Encore",
was a 27 kiloton weapon
launched from an aircraft and
landed at an altitude of approximately 850m
over a wide line
deflagration.
The second explosion of the Ministry
of Defense, called "Grable"
exploded in the same region,
and was launched by the new
cannon artillery of the army.
A 280mm projectile was launched
and exploded in the same area
with a power of about 15 kilotons,
at an altitude of approximately 150 meters.
The least powerful,
15 kilotons to 150 meters,
produced a much greater destruction
that the higher power device,
Still, 27 kilotonnes of 850m.
This is because less energy
low-lying
produces a shock wave abnormal
we now call "Pre Crusher"
that generates very violent
wind dynamic
generating for the target
very serious damage.
For example, a Jeep on the ground, had
not damaged especially with Encore,
but with Grable and
effect "Pre Crusher"
the same jeep was
broken into pieces,
and thrown out on
a distance of 150 meters.
There are many other features
these two launches,
but they opened a whole new view
on how to use weapons
nuclear in a combat situation.

The 21st test conducted during the operation
Plumbbob the event was "Rainier."
It was the first explosion completely
led underground by United States.
The device exploded three kilotons
240m to under Mount Rainier,
spraying of the powder of rock
within 30 meters.
This technology will be of great importance
after the Treaty of restriction tests
banning all nuclear tests,
except underground
and to hide future experiments
from prying eyes.
During Operation Hardtack, the United States
detonated 35 nuclear devices,
as well as in all previous tests
the Pacific.
So far, nuclear testing
were seen largely
practice as intimidation,
increasing international tensions
that could lead
a nuclear war.
Against the increasing pressure,
the U.S. Government believed
although the weapons are essential,
and they are the only counterweight to
increasing the number of Soviet soldiers.
The Russians, having developed and finalized
a series of atmospheric tests,
pretended to surrender
tests, knowing full well
the United States had undertaken
a major operation.
Operations were conducted
Bikini and Enewetak in as before.
And a new site was created
Hardtrack for the operation,
Johnston Island.
During testing, one of the events
significant event was the Cactus.
It was a small device
18 kilotonnes of which produced
a crater about 42m wide
and 11m deep.
Many years later, in 1980,
all debris from the fission
and radioactive materials that
were in the Enewetak Atoll
were collected and disposed
in the crater of the bomb Cactus.
Then we placed a concrete dome
on the crater
to maintain and stabilize
radioactive materials.
A year before Hardtack,
the Soviets launched a small
satellite named "Sputnik-1."
Concerned about the superiority
Soviet missiles,
the United States have made
their first two shots
missiles at high altitudes,
known under the names "Teac" and "Orange".
Nuclear weapons from Teac and Orange
were carried into space
by a Redstone rocket,
developed by Wernher Von Braun.
Von Braun and his team
have developed
the V2 rocket for Germany
during World War II.
The Redstone was considered
an extension of the technology
the Second World War,
and was limited in scope.
Using liquid oxygen
as fuel,
Redstone propelled its nuclear charge
in the upper atmosphere of Earth,
and released for firing.
Teac, with a power
of 3.8 megatonnes
exploded about 80 km
of the surface of the Earth.
The explosion created a violent disturbance
magnetic in the atmosphere
called EMP or electromagnetic pulse.
This silenced the
radios to nearly 8 hours,
And damaged electrical circuits
from Hawaii to New Zealand.
Immediately after the events

the United States led
"Operation Argus".

from 1 kiloton in the South Atlantic.
The experiment sought Argus
to create and explore the use

In autumn 1939,
Dr. Albert Einstein
wrote his famous letter

explaining the urgency of working
in the fission of uranium.
Roosevelt, a man of action,
responded quickly,
and creates an advisory committee
of uranium.

and the private sector,
leading to the creation of huge factories,
for the separation of uranium
in the town of Oakridge, Tennessee,
and for the production of plutonium

Through this effort was forged great
the necessary hardware
to create an atomic bomb.
The first atomic bomb
was built at Los Alamos,
a secret laboratory
New Mexico
When Dr. Oppenheimer J.R.
arrived to take command
he surrounded himself with an incredible range
stars of the scientific world.
Los Alamos was born on design
the bomb and resolution
many theoretical problems.
Many questions remain unanswered, however.
What are the secrets of this new
form of power and destruction?
Knowledge and Information
all aspects of this new weapon
are essential,
and can not be discovered that
by further testing.
I had a good friend, a Hungarian
10 years older than me, Leo Szilard.
He had a very independent-minded
and a large capacity
foreshadow what would happen.
He saw the years ahead
the importance that the explosives
Nuclear would take.
He was a friend of mine, and I helped him.
For example, I took it to
an important interview with Einstein
where Einstein wrote this
famous letter to Roosevelt.
The letter that started it all.
I myself was interested in
Theoretical Physics
atoms, molecular vibrations,
and knowledge of molarity.
I did not want to do.
But then...
Hitler had not only swallowed
half of Poland,
he had also invaded the West.
Two days later, there was
an invitation to a Pan-American Congress
in which Roosevelt, that I had never
seen before, was to speak.
He made a memorable speech,
about how the world is
really in danger because of Hitler.
He said in part, to the point
highlight of the speech:
"You scientists, will be blamed
for the arms to be used"
but I tell you,
"if you do not work on these weapons,
world freedom will be lost."
You know, I felt
Roosevelt spoke to me.
I was there when
The letter was signed

in nuclear power
He was convinced that

Of the 2,000 scientists who were there,
I felt it spoke to me.
Of course it was not that...
But for this speech
twenty minutes
I made my decision.
I continued to prefer
work in science 'pure',
but this must be done.
Since this must be done
and that I could contribute,
I did,
and I have never regretted
to have done.
The uranium bomb,
called "Little Boy"
had a simple design.
And scientists were convinced
fonctionnerai it without testing.
"Fat Man", or the implosion bomb,
was a more efficient design
which used plutonium
rather than uranium.
In the center of the bomb,
there was a detonator
surrounded by a sphere of plutonium.
This sphere was encapsulated
in a series of lenses highly
explosive placed symmetrically,
creating an implosion
compressing the sphere of plutonium
on itself until it
reaches critical mass.
The explosion brought immediately
temperature to 10 million degrees,
releasing a force of one half

OPERATION CROSSROADS
11 months after the bombing

the operation was conducted Crossroads
on Bikini Atoll
4000km to the west of Hawaii.
The aim of the operation
was to test the effects of weapons
nuclear using two devices
similar in design to those
Trinity and Nagasaki.
Their code names:
"Able" and "Baker".
Able to be launched
from a B-29,
while Baker was detonated
to 30 m below the water surface.
The fleet consisted of target

created by United States
as a research center
and development of nuclear weapons.
We are talking about a region

laboratories and their States,
for a term which may
reach for months.
Since 1943, when
Los Alamos was founded,
these men left
the continental limits of the United States
to test weapons
they have created.
Two years after
Operation Crossroads,
President Truman authorized
to conduct the operation Sandstone.
While the goal of Crossroads
was to test the effect
nuclear weapons,
Sandstone objective was to test
design new weapons.
Plans for these weapons were
initiated several years earlier
when researchers from Trinity
have developed other models
experimental atomic weapons,
but were not sure of their success.
A joint working group was created
to go back into the peaceful,
and obtain the island of Enewetak,

necessary for the operation Sandstone.
Perched on steel towers
60 meters high,
the three devices used to Sandstone
employed a new technology
to double the explosive power

The results of Sandstone affectrent
the design of future nuclear weapons,
making the components 'Mark-3', used

led to better performance and a
lighter weight for nuclear weapons.

the use of tactical nuclear weapons.
"TRUMAN SAYS RUSSIAN

On 29 August 1949, the Russians did
exploded their first atomic bomb.
This event,
which took place five years earlier
than anyone in the west
have been expected,
was largely responsible
a man, Klaus Fuchs.
Fuchs, a physicist at Los Alamos,
spent blueprints

Trinity to the Russians.
With the emergence of the USSR
as a nuclear rival in 1949,
the United States were convinced

It was very expensive and it
involved a lot of logistics

in the Pacific.
In this and in January 1951, the United States
inaugurated the test area of?? Nevada,
we now call
"The Nevada Test Site"
which is located approximately 100 km
north of Las Vegas.
Before you can test the

A trial approximately 45.5 kilotonnes
in which tritium was burned
in the center of the nuclear explosion.
And this process, placing the center of tritium

more than double,
through this process.
A very important feature

The second explosion of the Ministry
of Defense, called "Grable"
exploded in the same region,
and was launched by the new
cannon artillery of the army.
A 280mm projectile was launched
and exploded in the same area
with a power of about 15 kilotons,
at an altitude of approximately 150 meters.

the fall of 1957, with a moratorium
on tests looming on the horizon,
24 nuclear tests were
conducted in the Nevada desert
Operating under the name "Plumbbob".
During Plumbob, the event "Hood"
became the most powerful test
ever made in the atmosphere
of the continental United States .
Hood, a 74 kiloton device,
was suspended at 500 m above
the desert floor in a ball.
As new models of weapons
continued to be tested,
the Ministry of Defence
tests used
to accelerate the military training
in the nuclear battlefield,
while pursuing the study of
effects of nuclear explosions.
The 21st test conducted during the operation
Plumbbob the event was "Rainier."
It was the first explosion completely
led underground by United States.
The device exploded three kilotons
240m to under Mount Rainier,
spraying of the powder of rock
within 30 meters.
This technology will be of great importance
after the Treaty of restriction tests
banning all nuclear tests,
except underground
and to hide future experiments
from prying eyes.
During Operation Hardtack, the United States
detonated 35 nuclear devices,
as well as in all previous tests
the Pacific.
So far, nuclear testing
were seen largely
practice as intimidation,
increasing international tensions
that could lead
a nuclear war.
Against the increasing pressure,
the U.S. Government believed
although the weapons are essential,
and they are the only counterweight to
increasing the number of Soviet soldiers.
The Russians, having developed and finalized
a series of atmospheric tests,
pretended to surrender
tests, knowing full well
the United States had undertaken
a major operation.
Operations were conducted
Bikini and Enewetak in as before.
And a new site was created
Hardtrack for the operation,
Johnston Island.
During testing, one of the events
significant event was the Cactus.
It was a small device
18 kilotonnes of which produced
a crater about 42m wide
and 11m deep.
Many years later, in 1980,
all debris from the fission
and radioactive materials that
were in the Enewetak Atoll
were collected and disposed
in the crater of the bomb Cactus.
Then we placed a concrete dome
on the crater
to maintain and stabilize
radioactive materials.
A year before Hardtack,
the Soviets launched a small
satellite named "Sputnik-1."
Concerned about the superiority
Soviet missiles,
the United States have made
their first two shots
missiles at high altitudes,
known under the names "Teac" and "Orange".
Nuclear weapons from Teac and Orange
were carried into space
by a Redstone rocket,
developed by Wernher Von Braun.
Von Braun and his team
have developed
the V2 rocket for Germany
during World War II.
The Redstone was considered
an extension of the technology
the Second World War,
and was limited in scope.
Using liquid oxygen
as fuel,
Redstone propelled its nuclear charge
in the upper atmosphere of Earth,
and released for firing.
Teac, with a power
of 3.8 megatonnes
exploded about 80 km
of the surface of the Earth.
The explosion created a violent disturbance
magnetic in the atmosphere
called EMP or electromagnetic pulse.
This silenced the
radios to nearly 8 hours,
And damaged electrical circuits
from Hawaii to New Zealand.
Immediately after the events

the United States led
"Operation Argus".

from 1 kiloton in the South Atlantic.
The experiment sought Argus
to create and explore the use

For two years, a moratorium
difficult on nuclear testing
remains between the United States
and the Soviet Union.
In secret, the Soviets
began to design
new weapons of mass destruction.
Including a hydrogen bomb
of 57 megatons,
the largest nuclear weapon ever created.
This monstrous bomb
was a smaller version
a model of 100 megatons,
and could be transported
and launched from an aircraft.

Because today, Mr. President,

The Russians had broken
a voluntary moratorium.
the United States responded quickly
by a wide range of weapons testing
in retaliation for a large scale.
The tension rises when near
100 nuclear tests were conducted
between the test area in Nevada
and the Pacific Ocean,
under the code names Nougat,
Storax and Dominic.
