In 1942 the Manhattan Engineer Project was set up in the United States under the command of Brigadier General Leslie Groves. Scientists recruited to produce an atom bomb included Robert Oppenheimer (USA), David Bohm (USA), Leo Szilard (Hungary), Eugene Wigner (Hungary), Rudolf Peierls (Germany), Otto Frisch (Germany), Niels Bohr (Denmark), Felix Bloch (Switzerland), James Franck (Germany), James Chadwick (Britain), Emilio Segre (Italy), Enrico Fermi (Italy), Klaus Fuchs (Germany) and Edward Teller (Hungary). \n\nhttp://www.spartacus.schoolnet.co.uk/USAmanhattan.htm\n\nThe Manhattan Project took over control of U.S. fission research, which had begun in 1939, starting in the fall of 1942, and resulted in the design, production, and detonation of three nuclear bombs in 1945. The first, using plutonium made at the Hanford, Washington, plant, was tested on July 16 as "Trinity", the world's first nuclear test, near Alamogordo, New Mexico. The second, an enriched uranium bomb code-named "Little Boy", was detonated on August 6, over Hiroshima, Japan. The third, another plutonium bomb, code-named "Fat Man", was detonated on August 9, over Nagasaki, Japan.\n\nThe primary sites of the project exist today as Hanford Site, Los Alamos National Laboratory, Oak Ridge National Laboratory, the National Security Complex and several other plants. The MED maintained control over U.S. weapons production until the formation of the Atomic Energy Commission in January 1947.\n\nAt its peak in 1945, the Project employed over 130,000 people, and cost a total of nearly $2 billion USD.\n\nhttp://en.wikipedia.org/wiki/Manhattan_Project

The A-bomb generates its massive amount of energy using fission.  When intense pressure is applied to the radioactive material, the nuclei of the atoms within split apart, releasing tremendous amounts of energy.\n\nThe H-bomb generates its energy through fusion.  An A-bomb is required to start the process.  When the A-bomb goes off, tremendous pressure is applied to a hydrogen core, which causes the hydrogen atoms to fuse into helium atoms.  The reaction results in a reduction of mass.  The 'lost' mass is converted into energy, which results in a huge explosion.  The H-bomb is considerably more powerful than an A-bomb.\n\nThe theoretical next step would be a carbon-bomb, which would require an H-bomb to induce fusion in a carbon core.  These bombs could be powerful enough to blow a hole through the crust, revealing the mantle beneath.

Is this a question, or a US bashing, I'm not sure. I often ask myself that same question though. The most honest answer might be because we can control our technology, and we have the power to control proliferation too because we see it as a danger. In general, it's probobly not a good idea for every Tom, Dick, and Harry to have Atom bombs. Do you really think nothing bad would happen if every country had enough bombs to destroy the planet? Yea that would be swell. \n\nI do have to admit there is a certain irony to the United States being so controling about nukes. We say we can't trust others to have them, but who's the ONLY county crazy enough in the history of the world to actually use one... Yep.

Hydrogen bomb or H-bomb,weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy. Unlike this fission bomb, the hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements. The end product again weighs less than its components, the difference once more appearing as energy. Because extremely high temperatures are required in order to initiate fusion reactions, the hydrogen bomb is also known as a thermonuclear bomb.\n\nThe first thermonuclear bomb was exploded in 1952 at Enewetak by the United States, the second in 1953 by Russia (then the USSR). Great Britain, France, and China have also exploded thermonuclear bombs, and these five nations comprise the so-called nuclear club—nations that have the capability to produce nuclear weapons and admit to maintaining an inventory of them. The three smaller Soviet successor states that inherited nuclear arsenals (Ukraine, Kazakhstan, and Belarus) relinquished all nuclear warheads, which have been removed to Russia. Several other nations either have tested thermonuclear devices or claim to have the capability to produce them, but officially state that they do not maintain a stockpile of such weapons; among these are India, Israel, and Pakistan. South Africa's apartheid regime built six nuclear bombs but dismantled them later.\n\nThe presumable structure of a thermonuclear bomb is as follows: at its center is an atomic bomb; surrounding it is a layer of lithium deuteride (a compound of lithium and deuterium, the isotope of hydrogen with mass number 2); around it is a tamper, a thick outer layer, frequently of fissionable material, that holds the contents together in order to obtain a larger explosion. Neutrons from the atomic explosion cause the lithium to fission into helium, tritium (the isotope of hydrogen with mass number 3), and energy. The atomic explosion also supplies the temperatures needed for the subsequent fusion of deuterium with tritium, and of tritium with tritium (50,000,000°C and 400,000,000°C, respectively). Enough neutrons are produced in the fusion reactions to produce further fission in the core and to initiate fission in the tamper.\n\nSince the fusion reaction produces mostly neutrons and very little that is radioactive, the concept of a “clean” bomb has resulted: one having a small atomic trigger, a less fissionable tamper, and therefore less radioactive fallout. Carrying this progression further would result in the suggested neutron bomb,. which would have a minimum trigger and a nonfissionable tamper; there would be blast effects and a hail of lethal neutrons but almost no radioactive fallout; this theoretically would cause minimal physical damage to buildings and equipment but kill most living things. The theorized cobalt bomb. is, on the contrary, a radioactively “dirty” bomb having a cobalt tamper. Instead of generating additional explosive force from fission of the uranium, the cobalt is transmuted into cobalt-60, which has a half-life of 5.26 years and produces energetic (and thus penetrating) gamma rays. The half-life of Co-60 is just long enough so that airborne particles will settle and coat the earth's surface before significant decay has occurred, thus making it impractical to hide in shelters. This prompted physicist Leo Szilard to call it a “doomsday device” since it was capable of wiping out life on earth.\n\nLike other types of nuclear explosion, the explosion of a hydrogen bomb creates an extremely hot zone near its center. In this zone, because of the high temperature, nearly all of the matter present is vaporized to form a gas at extremely high pressure. A sudden overpressure, i.e., a pressure far in excess of atmospheric pressure, propagates away from the center of the explosion as

we dropped lots and lots and lots of bombs on japan, too many to count or even name each one...so i take you are talking about the atomic ones named: fatman and little boy\n\nLittle Boy was dropped from a B-29 bomber piloted by U.S. Army Air Force Col. Paul W. Tibbets. Tibbets had named the plane Enola Gay after his mother the night before the atomic attack.\n\nMajor Charles W. Sweeney piloted the B-29, #77 that dropped Fat Man. After the nuclear mission, #77 was christened Bockscar after its regular Command Pilot, Fred Bock.\n\non an ineresting note, one reason Hiroshima and Nagasaki were picked as locations was due in large part to the fact that we had already destroyed much of every other city through fire-bombing.

The atomic theory, which holds that matter is composed of tiny, indivisible particles in constant motion, was proposed in the 5th cent. B.C. by the Greek philosophers Leucippus and Democritus and was adopted by the Roman Lucretius.

He was a chemist who discovered guncotton and ozone.  I'm sure Wiki would have an entry on him, and maybe some actual refrences

General Leslie Groves was the chief project engineer - he later went on to manage The Manhattan Project, which built the atomic bomb.\n\nGround was broken for the Pentagon on September 11, 1941, with construction completed in approximately sixteen months at a cost of $83 million.\n\nDuring the early years of World War II, with construction supervised by the future Manhattan Project supervisor Leslie Groves, 680,000 tons (620,000 tonnes) of sand and gravel were dredged from the nearby Potomac River for the new building, which were then processed into 435,000 cubic yards (330,000 m³) of concrete and molded into the pentagon shape. Very little steel was used in its design due to the needs of the war effort.\n\nThe primary reason for building it was the World War II required a massive increase of personnel at the War Department, and they needed a building large enough to hold everybody.

before rutherford, the atom was considered to be a homogenous object - kind of blobby and with its mass evenly spread out in space.  the current model of the atom with the mass concentrated in the nucleus at the center was rutherford's creation.  furthermore, rutherford didn't merely theorize the existence of the nucleus, he experimentally verified it.  \n\n(actually there is kind of a neat story to this - rutherford had been forced to take on an undergraduate student, named ernst marsden.  rutherford was investigating the way a thin foil of gold could make a beam of alpha particles spread out and become diffuse.  \n\ndealing with the undergrad was kind of a hassle, so rutherford got him out of his hair by giving him a task to keep the student busy - looking for particles reflected backwards from the foil.  \n\nhe didn't expect marsden to find anything, but was certainly surprised when the young student did, and this discovery of back-scattered radiation was some of the first (and still, damned good) evidence for the existence of the nucleus.)\n\nhe also generated the modern theory of radioactivity, was the first person to cause (by artificial means) a nuclear reaction, experimentally verified the age of the earth, invented a radiation-sensing device that was the precursor to the geiger counter, and even discovered the phenomenon that modern smoke detectors use in their normal operation.  all in all, he was a giant in the annals of physics.

Anit-matter is related to the atomic bomb? How?  The "atomic" bomb was a device that created a nuclear fission chain reaction.  No anti-matter was used.  The modern "nuclear" or "hydrogen" bombs are fusion devices (which create the energy needed for the fusion reaction by first detonating an atomic fission device), but still, no anti-matter involved.  \nNow, a positron (or the anti-electron) can come about under certain circumstances of a photon interacting with things such as carbon or fluorine and a couple others causing beta particle decay, but none of the right elements was used in any bomb.

Kids bits in brackets :)\n\nAn atom bomb works by firing a proton/neutron (a little part of an atom) at a mass of uranium (nuclear material) the proton goes into the uranium and eventually hits and joins with an atom of uranium, that atom is now unstable (a bit like too many people on a ladder) so to make it self stable it loses some protons (some people fall off the ladder), usually 2 or 3 (that's the bit they call fission), these fire off and hit other atoms repeating the process in a chain. if the amount of uranium is small then a lot of the protons fly out of the uranium and do nothing, however if there is enough uranium the protons are contained in the mass and break up even more atoms, leading to a catastrophic chain reaction (KaaaaBOOOOOOM)!!! \n\n***Try shouting the last part it should get a few laughs :)\n\nPS. because the uranium lost more protons than was originally put into it as extra, it is no longer standard uranium, this is called a uranium isotope.\n\nbrubeck_take5 yeah I remember the ping-pong ball video... really cool, wouldn't mind seeing that again... gonna see if I can find it... let you know :)\n\nhere goes... thing the slow motion one is the best\n\nhttp://www.ap.stmarys.ca/demos/content/modern/mousetrap_reactor/trap_sideview_slow_high.wmv\n\nbut if you want to look at them all\n\nhttp://www.ap.stmarys.ca/demos/content/modern/mousetrap_reactor/mousetrap_reactor.html

He invented nothing.  He revolutionized the world with a paper in 1905 and he developed the equation E = mc(squared) which ulimately led to being proved by nuclear fission and the detonation of the atomic bomb.

An hydrogen bomb is a nuclear bomb--so is an atomic bomb.
