On August 2, 1939, just before the beginning of World War II,Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as "The Manhattan Project." Simply put, the Manhattan Project was committed to expediting research that would produce a viable atomic bomb.
Making Enriched Uranium
The most complicated issue to be
addressed in making of an atomic bomb was the production of ample amounts of
"enriched" uranium to sustain a chain reaction. At the time,
uranium-235 was very hard to extract. In fact, the ratio of conversion from
uranium ore to uranium metal is 500:1. Compounding this, the one part of
uranium that is finally refined from the ore is over 99% uranium-238, which is
practically useless for an atomic bomb. To make the task even more difficult,
the useful U-235 and nearly useless U-238 are isotopes, nearly identical in
their chemical makeup. No ordinary chemical extraction method could separate
them; only mechanical methods could work.
A massive enrichment laboratory/plant was constructed at Oak
Ridge, Tennessee. Harold Urey and his colleagues at Columbia University devised
an extraction system that worked on the principle of gaseous diffusion, and Ernest
Lawrence(inventor of the Cyclotron) at the University of California in
Berkeley implemented a process involving magnetic separation of the two
isotopes.
Next, a gas centrifuge was used to further separate the
lighter U-235 from the heavier, non-fissionable U-238. Once all of these
procedures had been completed, all that needed to be done was to put to the
test the entire concept behind atomic fission splitting the atom,"
in layman's terms.
Robert Oppenheimer - Manhattan Project
Over the course of six years, from
1939 to 1945, more than $2 billion was spent during the history of the
Manhattan Project. The formulas for refining uranium and putting together a
working atomic bomb were created and seen to their logical ends by some of the
greatest minds of our time. Chief among the people who unleashed the power of
the atom was Robert Oppenheimer, who oversaw the project from conception to completion.
Testing The Gadget aka Atomic Bomb
Finally, the day came when all at
Los Alamos would find out if "The Gadget" (code-named as such during
its development) was going to be the colossal dud of the century or perhaps an
end to the war. It all came down to a fateful morning in midsummer, 1945.
At 5:29:45 (Mountain War Time) on July 16, 1945, in a white
blaze that stretched from the basin of the Jemez Mountains in northern New
Mexico to the still-dark skies, "The Gadget" ushered in the Atomic
Age. The light
of the explosion then
turned orange as the atomic fireball began shooting upwards at 360 feet per
second, reddening and pulsing as it cooled. The characteristic mushroom cloud
of radioactive vapor materialized at 30,000 feet. Beneath the cloud, all that
remained of the soil at the blast site were fragments of jade green radioactive
glass created by the heat of the reaction.
The brilliant light from the
detonation pierced the early morning skies with such intensity that residents
from a faraway neighboring community would swear that the sun came up twice that
day. Even more astonishing is that a blind girl saw the flash 120 miles away.
Upon witnessing the
explosion, its creators had mixed reactions. Isidor Rabi felt that the
equilibrium in nature had been upset as if humankind had become a threat to the
world it inhabited.
After viewing the results several participants signed petitions against loosing the monster they had created, but their protests fell on deaf ears. The Jornada del Muerto of New Mexico would not be the last site on planet Earth to experience an atomic explosion.

Anti Nuke Campaigns.
Greenpeace has always fought and continues to fight vigorously against nuclear power because it is an unacceptable risk to the environment and to humanity. The only solution is to halt the expansion of all nuclear power, and for the shutdown of existing plants.
Nastya, from Belarus was only three years old when she was
diagnosed with cancer of the uterus and lungs. According to local doctors the
region has seen a huge increase in childhood cancer cases since the Chernobyl
disaster.
The Campaign for Nuclear Disarmament is an organisation that advocates
unilateral nuclear disarmament by
the United Kingdom, international nuclear disarmament and tighter international
arms regulation through agreements such as the Nuclear Non-Proliferation Treaty.
It opposes military action that may result in the use of nuclear, chemical or biological weapons and the building of nuclear power stations in the UK.
CND was formed in 1957 and since that
time has periodically been at the forefront of the peace movement in the UK. It claims to be Europe's largest single-issue peace campaign. Between 1959 and
1965 it organised the Aldermaston March, which was held over the Easter weekend from the Atomic Weapons Establishment near Aldermaston to Trafalgar Square, London. The first
Aldermaston March in 1958 went the other way (from London to Aldermaston) and
was organised by the Direct Action Committee.
CND's
current strategic objectives are:
·
The elimination of British nuclear
weapons and global abolition of nuclear weapons. It campaigns for the
cancellation of Trident by the British government and against the deployment of
nuclear weapons in Britain.
·
The abolition of weapons of mass destruction, in particular chemical and biological weapons. CND wants a
ban on the manufacture, testing and use of depleted uranium weapons
·
A nuclear-free, less militarised and
more secure Europe. It supports the Organisation
for Security and Co-operation in Europe (OSCE). It opposes US
military bases and nuclear weapons in Europe and British membership of NATO.
·
The closure of the nuclear
power industry.
In
recent years CND has extended its campaigns to include opposition to U.S. and
British policy in the Middle
East, rather as it broadened its
anti-nuclear campaigns in the 1960s to include opposition to the Vietnam War.
In collaboration with the Stop the War Coalition and the Muslim Association of Britain, CND has organised anti-war marches under the slogan "Don't Attack Iraq",
including protests on September 28, 2002 and February 15, 2003. It also organised a vigil for the victims of the 2005 London bombings.
CND
campaigns against the Trident
missile. In March 2007 it organised a rally
in Parliament Square to coincide with the Commons motion to renew the weapons
system. The rally was attended by over 1,000 people. It was addressed by Labour
MPs Jon Trickett, Emily
Thornberry, John McDonnell, Michael
Meacher, Diane
Abbott and Jeremy
Corbyn, and Elfyn Llwyd of Plaid
Cymru and Angus
MacNeil of the Scottish National Party. In the House of Commons, 161 MPs (88 of them Labour) voted
against the renewal of Trident and the Government motion was carried only with
the support of Conservatives.
In
2006 CND launched a campaign against nuclear power. Its membership, which had
fallen to 32,000 from a peak of 110,000 in 1983, increased threefold after
Prime Minister Tony Blair made
a commitment to nuclear energy.
The anti-nuclear movement is a social movement that opposes various nuclear technologies. Some direct action groups, environmental groups, and professional organisations have identified themselves with the
movement at the local, national, and international level. Major anti-nuclear groups include Campaign for Nuclear Disarmament, Friends of the Earth, Greenpeace, International
Physicians for the Prevention of Nuclear War, and theNuclear Information and Resource
Service. The initial objective of the movement was nuclear disarmament, though some of the focus
has shifted to include opposition to the use of nuclear power.
There have been many large
anti-nuclear demonstrations and protests.
A protest against nuclear power occurred in July 1977 in Bilbao, Spain, with up to
200,000 people in attendance. Following the Three Mile Island accident in 1979, an anti-nuclear protest was
held in New York City, involving 200,000 people. In 1981, Germany's largest
anti-nuclear power demonstration took place to protest against the Brokdorf Nuclear Power Plant west of Hamburg; some 100,000 people
came face to face with 10,000 police officers. The largest anti-nuclear protest
was held on June 12, 1982, when one million people demonstrated in New York City against nuclear weapons.
A 1983 nuclear weapons protest in West Berlin had about 600,000 participants. In May
1986, following the Chernobyl disaster, an estimated 150,000 to
200,000 people marched in Rome to protest against the Italian nuclear program.
For many years after the 1986
Chernobyl disaster nuclear power was off the policy agenda in most countries,
and the anti-nuclear power movement seemed to have won its case. Some
anti-nuclear groups disbanded. In the 2000s, however, following public relations activities by the nuclear industry, advances in nuclear reactor designs, and
concerns about climate change,
nuclear power issues came back into energy policy
discussions in some countries. The 2011 Japanese nuclear accidents subsequently undermined the nuclear
power industry's proposed renaissance and revived anti-nuclear passions
worldwide, putting governments on the defensive. As of 2011, countries such as Australia, Austria, Denmark,Greece, Ireland, Italy, Latvia, Lichtenstein, Luxembourg, Malta, Portugal, Israel, Malaysia, New Zealand, and Norway remain
opposed to nuclear power. Germany and Switzerland are phasing-out nuclear power.
Two survivors, Ms. Setsuko Thurlow and Mr. Yasuaki Yamashita, share their
reflections, remembrances and personal testimonies with Truman’s grandson, Mr.
Clifton Truman Daniel and Peace Boat Executive Committee Member Mr. Akira
Kawasaki. Mr. Daniel will recount his own journey toward understanding this
event, including encounters with survivors during a recent trip to Hiroshima
and Nagasaki, while Mr. Kawasaki will introduce the work that Peace Boat has
