VOICE ONE:
I'm Sarah Long.
VOICE TWO:
And I'm Steve Ember with People in America in VOA Special English. Today we
report about two scientists, J. Robert Oppenheimer and Enrico Fermi, who
helped lead the world into the nuclear age.
(THEME)
VOICE ONE:
It is July Sixteenth, Nineteen-Forty-Five. All is quiet in an American desert
at Alamogordo, New Mexico. Suddenly there is a terrible explosion. A huge
cloud rises from the Earth. The sky turns purple and yellow.
The first atomic bomb has been exploded. It is a test of the most deadly
weapon ever known. American officials are considering using this weapon to
try to end World War Two.
J. Robert Oppenheimer
J. Robert Oppenheimer is the head of the Los Alamos laboratory. It is the
creative center of the secret Manhattan Project, which made the explosion
possible. As the cloud rises, Mister Oppenheimer remembers words from the
Hindu holy book, the Baghavad Gita. He says: "For I am become death, the
destroyer of worlds."
VOICE TWO:
Less than one month after the test at Alamogordo, the United States dropped
atomic bombs on two Japanese cities. President
Harry1 Truman announced to the
world about the first bomb:
ACT ONE: TRUMAN READING ANNOUNCEMENT OF THE DROPPING OF THE BOMB AT
HIROSHIMA. (15 secs)
The Japanese soon surrendered. World War Two ended.
VOICE ONE:
Enrico Fermi had been the first to use a
neutron2 to produce the radioactive
change of one element to another. He was a refugee from
Fascist3 Italy. He and
other refugee scientists were worried that Germany was working to develop an
atomic bomb. They urged the United States government to pay for a secret
scientific effort, called the Manhattan Project, to create the bomb. Mister
Fermi helped Mister Oppenheimer prepare the Alamogordo bomb test.
Yet later both Mister Oppenheimer and Mister Fermi
spoke4 against further
development of nuclear weapons. Both men opposed the hydrogen bomb.

VOICE TWO:
J. Robert Oppenheimer was born in New York City on April Twenty-Second,
Nineteen-Oh-Four. Even as a boy, he showed he had unusual intelligence. As a
young man he attended Harvard University, in the eastern United States, and
Cambridge University in England.He earned his
doctorate5 in physics at
Gottingen University, Germany, in Nineteen-Twenty-Seven. There he worked with
the famous scientist, Max Born. By Nineteen-Thirty, Mister Oppenheimer was
teaching at two top universities on the American West Coast. His fame as a
teacher spread. Soon he was teaching the best students of physics in the
United States.
VOICE ONE:
In Nineteen-Forty-Two, Mister Oppenheimer joined the American government's
project to develop the atomic bomb. He was appointed head of the Los Alamos
Laboratory. Many of his former students worked for him on the project.
One year after the bombs were dropped on Japan, he received the Presidential
Medal of Merit for his work . In Nineteen-Forty-Seven, he began to direct the
Institute of Advanced Studies at Princeton University on the East Coast.
VOICE TWO:
At the same time, Mister Oppenheimer became chairman of the
advisory6 committee to the United States Atomic Energy Commission. He used the position
to try to make the public recognize the dangers of nuclear power as well as
its possibilities for good.
He regretted that work was being done to develop the hydrogen bomb. He felt
it was bad for both scientific and
humanitarian7 reasons. However, extreme
tension existed between the United States and the
Soviet8 Union at the time.
So in Nineteen-Forty-Nine President Truman
decided9 that work on nuclear
weapons should continue.
VOICE ONE:
J. Robert Oppenheimer's life and work were
affected10 deeply by Americans
intense fear of Communism in the Nineteen-Fifties.
Mister Oppenheimer made an easy target for suspicious critics. His wife had
once been a Communist. Some of his friends were former Communists. Years
earlier he had suggested sharing nuclear secrets with the
Soviets11. He opposed
developing the hydrogen bomb.
In Nineteen-Fifty-Four, the Atomic Energy Commission and a special security
committee moved against Mister Oppenheimer. They did not question his
loyalty12 to the United States. However, they said his personal life made him a threat
to national security.
VOICE TWO:
Mister Oppenheimer had directed one of America's most important secret
scientific projects. Now this famous
physicist13 was barred from secret work
for the government.
He published several books during this difficult period of his life. One of
the best known was "The Open Mind." The books contained his thoughts about
science. He continued teaching at Princeton University. Again he taught many
of the most important scientists of our century.#p#副标题#e#
VOICE ONE:
In time Mister Oppenheimer's work in science and teaching made people forget
the
accusations14 against him. The government decided to give him the highest
award of the Atomic Energy Commission for his work on atomic energy.
President Lyndon Johnson presented the honor in late Nineteen-Sixty-Three. It
was called the Enrico Fermi Award.
J. Robert Oppenheimer died of throat cancer on February Eighteenth, Nineteen
-Sixty-Seven. He was sixty-two years old.

VOICE TWO:
Enrico Fermi
Enrico Fermi had worked with Robert Oppenheimer and other top scientists to
develop the atom bomb. He won an award for his work in atomic energy from the
Atomic Energy Commission in Nineteen-Fifty-Four. It was the first time the
award was presented. Later, the honor was named for him. It recognized Mister
Fermi as one of the greatest
physicists15 of the Twentieth Century.
VOICE ONE:
Enrico Fermi was born in Rome, Italy, on September Twenty-Ninth, Nineteen-Oh
-One. After his education in Italy, he studied with Max Born in Germany, just
as Robert Oppenheimer had.
Enrico Fermi returned to Italy in Nineteen-Twenty-Four. He became that
nation's first professor of theory of physics. At the time there was almost
no physics education offered in Italy
He married Laura Capon, who also was a scientist, in Nineteen-Twenty-Eight.
Laura was Jewish. Later the Fermis decided to leave Italy, because the
Fascist government had begun oppressing Jews.
VOICE TWO:
Enrico Fermi went to Stockholm, Sweden, to accept a Nobel Prize in Nineteen-
Thirty-Eight. He won for producing new radioactive elements beyond uranium.
Without knowing it, he had split the atom. However, that fact was not
recognized until later.
He and his family sailed directly from Stockholm to the United States. If he
stayed in Europe, he might have been forced to work for
Nazi16 Germany.
VOICE ONE:
Mister Fermi taught at Columbia University in New York City. He also was part
of the American research team for the top secret Manhattan Project
Mister Fermi led the team that created the world's first controlled,
continued nuclear-fission reaction. It happened on December Second, Nineteen
-Forty-Two, at the University of Chicago.
VOICE TWO:
Mister Fermi directed the building of the first atomic
reactor17 that made the
reaction possible. He had invented the method with another scientist, Leo
Szilard. The reactor was put together in a squash court under the seats of
the university sports center. It contained natural uranium placed in graphite
and controlled by pieces of cadmium and boron rods.
By, Nineteen-Forty-Four, Enrico Fermi had become a citizen of the United
States. He was asked to help Robert Oppenheimer with the atomic bomb test at
Alamogordo.
Mister Fermi returned to the University of Chicago after the war. There he
headed the Institute for Nuclear Studies, now known as the Enrico Fermi
Institute.
VOICE ONE:
Like Mister Oppenheimer, Mister Fermi recognized the dangers of atomic
energy. They both worried about the possible use of a hydrogen bomb. With
another scientist Mister Fermi wrote a Nineteen-Forty-Seven report to the
Atomic Energy Commission. The report opposed creation of the bomb for
humane18 reasons.
Enrico Fermi died of cancer in Chicago in Nineteen-Fifty-Four. He was fifty-
three years old.
VOICE TWO:
J. Robert Oppenheimer and Enrico Fermi were two of the greatest scientists of
the century. They were both concerned about the results of their discoveries
that led the world into the Nuclear Age.
