how was the atomic bomb hiroshima made?and whats the name of the person who did it?

The American government made the bomb that was dropped on Hiroshima, they generally do not release the blueprints. I can tell you that it was a gravity bomb, a gun-type fission weapon, with 60 kg (130 pounds) of uranium-235 encased in a bomb.See picture below.

Hydrogen bomb is an atomic bomb, it use fusion instead of fission. \nFusion as you may know is when 4 hydrogen atoms get together and make a Helium atom, this process release a Notrino and lots of energy but it can't be performed in normal circumstances like Fission bombs where a Uranium atom breaks into two smaller atoms and release energy.\nIf what I remember from physic classes is true in order to make a fusion reaction a very hot enevironment needed, so Hydrogen bombs consist of a Fission Bomb which make this heat and a Fusion bomb.\nIt has a normal atomic bomb inside.\nIt reminds me of the title of Dr. Strangelove: How I learned to stop worrying and love the Bomb.

An atomic bomb is composed of some heavy-duty explosives, U-235 or P-239, and a neutron source.\n\nThe neutron source is in the center, surrounded by the Uranium or Plutonium, and then the explosives. Upon detonation, the explosives explode simultaneously, crushing the nuclear material in on the neutron source. This causes the material to achieve critical mass and a massive chain reaction takes place. Very massive.

the United States military dropped atomic bombs on the cities of Hiroshima and Nagasaki, Japan on August 6 and August 9, 1945, respectively. At least 120,000 people, about 95% of which were civilian, were killed outright, and around twice as many over time.

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.

I assume you mean nuclear "bomb"...\n\nIn simplistic terms, and nothing you can't easily find elsewhere, a nuclear bomb is made up of material that fissions (meaning that its atoms can be split to release energy) - this is either Uranium-325 or Plutonium.  Uranium is found in nature but the vast majority is U-238 which doesn't fission - natural uranium must be enriched to create a fissionable amount of uranium - this is true for commercial power reactor fuel too.   Plutonium is made in nuclear reactors from bombarding other materials with neutrons.\n\nTo have a "nuclear yield" the fissionable material in a bomb must be forced into a 'critical mass' configuration which means that it is so dense (atoms close together) that once the material starts to fission and release energy and neutrons, other atoms will capture the released neutons and then they will fission releasing more energy and neutrons and so on and so on with the chain reaction making the boom.\n\nWith the early plutonium bombs (Fat Man), the material was in a sphere and was forced together with high explosives uniformly to create a ball (critical mass). In the first uranium bomb (Little Boy, which they didn't even test until it was dropped on Japan since they were confident it would work) 2 uranium blobs were forced together by essentially thrusting/throwing/shooting one to the other to create the critical mass.  The math behind all this physics is incredibly complex.\n\nTo add bang for the buck they started adding the gas Tritium, an isotope of hydrogen, hence the name Hydrogen bomb versus just the Atomic Bomb...  Tritium makes the yield much bigger.

It was invented by Micheal Faraday.  It was perfected by Robert Bunsen and his assistant, Peter Desaga.\n\nSee http://en.wikipedia.org/wiki/Bunsen_burner

-Many Japanese were put into internment camps in the main land U.S but there were no internment camps in Hawaii, which half of the population then was Japenese.\n-The name given to the secret project of building an atomic bomb was "The Manhatten Project."\n-The name of the plane that dropped the first bomb was "The Enola Gay."\n-The Japanese also held Americans in internment camps mostly in China.

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

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

The key words in your question are "create fire."  Fire doubtless was caused by lightning and put to use by early cave dwellers who had to keep the fire going.  But to create the first fire using flint or friction must have been a great leap forward.\n\nHowever, to understand nuclear reactions required mankind to model atoms which can not be seen and understand the presence and interaction of neutrons that have no charge and are difficult to even detect.  Still nature led the way to atomic energy by providing natural disintegration (radioactivity) of heavy elements; similar to natural fire?\n\nIn a way its a toss-up, considering the amount of prior art available to those that made the leaps.

In 1938, two German physicists, Otto Hahn and Fritz Straussman, discovered that a neutron caused the nucleus of a uranium atom to split (fission). Other experiments followed that showed that the energy released in fission was about 100 million times greater than a chemical reaction. At the onset of World War II, the military implications of this discovery were readily apparent to leaders of the major powers. Uranium was destined to find new, more important applications beyond its original use as a colorant for glass and ceramics.

In 1939, under the encouragement of Szilárd, Einstein sent a letter to President Franklin Delano Roosevelt urging the study of nuclear fission for military purposes, under fears that the Nazi government would be first to develop atomic weapons. Roosevelt started a small investigation into the matter which eventually became the massive Manhattan Project. Einstein himself did not work on the bomb project, however.\n\nThe International Rescue Committee was founded in 1933 at the request of Albert Einstein to assist opponents of Adolf Hitler

Uranium enrichment is the process of making those little things called electrons that are in atoms to become more and more unstable thus creating a highly unstable substance that is used for the core of.. you guessed it! The A bomb! There are different isotopes of atoms, usually uranium, and the more electrons you make it lose the more unstable it gets, Plutonium is used in bombs, plutonium is made from uranium for example. Have a nice day.

I would have to say that it would be impossible to know the answer, Pure speculation...however, after reviewing the facts:\n\n1. Japan had made overtures via Sweden of negotiating a peace prior to Hiroshima.\n2. However, they did openly turn down the Potsdam demands for unconditional surrender.\n3. Like you mentionioned, Iow Jima and Okinawa showed their army's determination to fight to the last man, altho it may not have proven that the civilians would've done the same on Japan proper.\n4. The first nuclear detonation did not bring immediate surrender from the Japanese leaders.\n5. By using the bomb, we lost the moral argument after the war that the A-bomb should be controlled and never used.\n6. The bombing of civilians was recognized as barbaric before the war and in the Geneva conventions, and yet the allies began using incendiaries on Dresden, Tokyo causing major firestorms.\n7. By ending the war earlier, we did not give the Soviets a chance to mount an offensive against Japan and create a Soviet Bloc as they did in Europe.\n8.Oppenheimer, Fermi and others considered the alternative, increased American casualties vs ending the war sooner by using the weapons, and they recommended the use of the bombs. There were some scientists who recommended a demonstration to show the Japanese leaders the potential devastation, but they were overrulled.\n\nMy opinion is that we did save Japanese lives that would've exceeded the number killed at Hiroshima and Nagasaki, vis a vis the continued encendiary bombing of Japanese cities and loss due to "fighting" to the last man mentality that showed at Iwo and Okinawa.\n\nThe number of allied lives saved, i would guess, would be around 200,000, but that's only pulling a number out of the sky...the US stated hundreds of thousands, if not more.
