  BBC ON THIS DAY | 9 | 1945: Atom bomb hits Nagasaki
The bomb was dropped by parachute from an American B29 Bomber at 1102 local time.
About 30% of Nagasaki, including almost all the industrial district was destroyed by the bomb and nearly 74,000 were killed and a similar number injured.
The bomb, nick-named "Fat Man" in a reference to Winston Churchill, measured just under 3.5m (11ft 4in) in length, had the power of 22 kilotons of TNT and weighed 4,050kg (9,000lbs).

  Atomic bombings of Hiroshima and Nagasaki - Wikipedia, the free encyclopedia
While the damage from these few bombs were relatively small, it created considerable concern in Nagasaki and a number of people—principally school children—were evacuated to rural areas for safety, thus reducing the population in the city at the time of the nuclear attack.
One of the prominent critics of the bombings was Albert Einstein.
Sadako Sasaki, a young victim of the bombing, became a well-known symbol of nuclear war and is now commemorated by a statue in Hiroshima, carrying a paper crane (a symbol of peace).

She moved to Sweden and later that year she wrote a paper on nuclear fission with her nephew, Otto Frisch, where they argued that by splitting the atom it was possible to use a few pounds of uranium to create the explosive and destructive power of many thousands of pounds of dynamite.
Some scientists argued that the technical problems involved in producing such a bomb were too difficult to overcome, but the one thing they were agreed upon was that if such a weapon was developed, it would give the country that possessed it the power to flmail the rest of the world.

The amount of energy generated by the bomb was equivalent to the amount of energy generated by a 15-kiloton TNT explosion.
For the period 1946 to 1951 the number of deaths due to the bomb was estimated at 60,000.
As the number of deaths among survivors, in the first ten years of the survey, showed little difference from the population as a whole it has been concluded that the number of people who died as a direct result of the bomb was approximately 200,000.

 Kiss Your Sorry Ass Goodbye! The Atom Bomb Is Gonna Fly.
The only real obstacle to building a bomb is obtaining the nuclear explosive; it requires either collosal amounts of electricity and a huge industrial plant to refine natural Uranium, or a large nuclear reactor and a great deal of time to synthesize enough Plutonium.
Until Iran tests, there is no way even they could know that their bomb would actually work; even though the general techniques of making a bomb are well-known, some aspects such as the explosive lenses and the initiator in a Plutonium bomb are tricky and hard to get right.
I won't discuss Hydrogen bombs in detail, except to say that a Plutonium bomb is used to both heat and compress Deuterium and Tritium, isotopes of Hydrogen with one or two neutrons in addition to its single proton.

 What is the Atom Bomb?
According to the Encyclopedia on yahoo.com, the atom bomb, or A-bomb, is a weapon that gets its explosive force from the release of atomic energy through the fission of heavy nuclei, resulting in nuclear energy.
Both bombs caused much death and destruction, and it is still debated to this day about whether or not it was neccassary to use these weapons of mass destruction.
The "little boy" bomb that was dropped on Hiroshima on Aug 6,1945, was a Gun-type fission bomb.

 BBC - h2g2 - How to Make your own Atom Bomb - A676352
It could be noted at this point that the Hiroshima bomb was only about 2% efficient, 98% of the fissile material was blasted away from the critical mass by the initial nuclear explosion, thus stopping the chain reaction long before it attained its maximum capacity.
Even if the bomb itself was extremely inefficient, one should expect total destruction within a radius of between 500 and 1000 metres, with heavy damage to buildings extending far beyond this perimeter.
If the bomb is detonated on the ground floor - or even better in the cellar - of the house, a crater, some 100 metres in diameter, and 5 to 6 metres deep would be formed, throwing thousands of tonnes of highly radioactive debris into the air.

Under a self-imposed flout on publication, further work in the United States and Britain was done in secret to prevent German scientists from using the findings to develop an atomic bomb of their own for use in the war then under way.
The blast effect of an atomic bomb is similar to that of a conventional explosive but much more intense and far-reaching.
The awesome difference was that damage on this scale could be inflicted by a single bomb carried in a single plane.

 Atom Bomb: Technique and theory used to make one
Instead of disintegrating slowly, the atoms are forcibly split by neutrons forcing their way into the nucleus.
A U-235 atom is so unstable that a blow from a single neutron is enough to split it and henceforth bring on a chain reaction.
When a U-235 atom splits, it gives off energy in the form of heat and Gamma radiation, which is the most powerful form of radioactivity and the most lethal.

 Nuclear weapon : Atom Bomb   (Site not responding. Last check: 2007-09-22)
Fission bombs derive their power from nuclear fission, where heavy nuclei (uranium or plutonium) split into lighter elements when bombarded by neutrons (produce more neutrons which bombard other nuclei, triggering a chain reaction).
These are historically called atom bombs or A-bombs, though this name isn't precise due to the fact that chemical reactions release energy from atomic bonds and fusion is no less atomic than fission.
Despite this possible confusion, the term atom bomb has still been generally accepted to refer specifically to nuclear weapons, and most commonly to pure fission devices.
