Einstein has some credit in the development of the nuclear bomb,but never thought of it himself... I believe it was Hitler whofirst thought of the atomic bomb. The Germans were working on a wayto harness the energy from a split atom. Einstein sent the USpresident a letter, telling him of the power s…uch a weapon couldhave, and the Germans were working on splitting atoms. That broughtabout the Manhattan Project. ------------------------------------------------------------------------------------------------------------- The Einstein letter to FDR was actually entirely writtenby Leo Szilard , all Einstein did was sign it. The writer H.G. Wells had imagined them and wrote about them in his1914 novel "The World Set Free", but this was just SciFi. Leo Szilard was the first to actually invent the process that makesthe atomic bomb work (neutron chain reaction) in 1933 while inLondon and patented this on June 28, 1934. A team of German scientists working in Germany and Swedendiscovered fission in uranium-235 in 1939 and after the publicationof their paper, Germany blocked further publication of the resultsof all research in nuclear physics. By the time the Manhattan Project became fully active, Germany hadalready decided to scale back their nuclear project to just basicreactor research with the single goal of building powerreactors after Germany won the war . Theyconsidered a bomb impractical in the time estimated to win the warby conventional means, even if it was possible (and Heisenberg'scalculations suggested such a bomb would be too large for anyavailable aircraft to deliver). To Hitler the idea of an Atomic Bomb sounded like JewishPhysics , and thus nonsense. Hitler knew nothing ofphysics , nuclear or otherwise, and the teaching ofEinstein's theories of relativity were already banned in NaziGermany simply because Einstein was a Jew (implicitly making it Jewish Physics ) regardless of any experimental evidenceconfirming the theories.

the Atomic Bomb was created in less then two years. it took a year and a half. Also Timmy Is the BO$$ and is the best person in the world
because atom, when split become highly unstable, and in whats called nuclear fission, atoms are divided inot smaller ones, and that on a large scale is devestating.
The a-bomb was built in Oak Ridge, Tennessee - just outsideKnoxville. ----------------------------------------------------------------------------------------------------------------------- All atomic bombs built in 1945-1947 were built in Los Alamos,NM. Oak Ridge, TN only supplied the oralloy (Oa…k Ridge "alloy":weapons grade 80% enriched uranium) while Hanford, WA supplied theplutonium and polonium. The Navy supplied cordite and highexplosives. Sandia in Albuquerque, NM supplied the custom bombcasings and electronics. Later factories (e.g. PANTEX in TX, RockyFlats in CO) were built to do the assembly. (MORE)
That depends on a person's proximity to the hypocenter of the blast. The further away you are, even from a very large bomb, generally the better off you are, but there are many, many mitigating factors. If you were at Hiroshima, Japan on the morning of August 6, 1945, and you happened to be stand…ing on the bridge that was the aiming point for the first atomic bomb ever dropped in combat, you would have been literally vaporized. There would have been nothing left of you but the shadow you cast when the bomb went off (there were such shadows cast and recorded on the surrounding concrete that was not destroyed). But the further away people were, depending on where they were and what sort of building they were in, or behind, their chances of surviving the initial blast rose pretty much proportionally by the distance from the hypocenter. Yet there were always exceptions; buildings that collapsed on people; people that were exposed to the direct radiation of the blast; and other factors too numerous to detail. The other thing about a nuclear explosion, though, is the radiation exposure, and that also tended to be proportional to distance and what sort of shelter (if any) you had. Some people were relatively quite close to the hypocenter yet lived, even without radiation burns, while people miles away were terribly burned. It all depended on where they were and what type of exposure they received. But the really insidious thing about a nuclear explosion or even a nuclear accident is the exposure to residual radiation. People who went into the blast area to try to rescue other people were exposed to very high doses of radiation. Many of them died in the next few days and weeks. There are people dying of radiation induced cancer to this day in Hiroshima and Nagasaki, and some may never know whether the initial cancer was radiation induced or from some other cause, since causes of cancer are not yet completely understood. Below are a couple of websites, one on nuclear weapons, and the other on the Chernobyl meltdown in Ukraine in 1986. If you read the one on Chernobyl carefully, you will learn a lot about radiation sickness. Hundreds were sickened, many died almost immediately, and the aftereffects will be felt for many years. Chernobyl itself is uninhabitable because the radiation levels are still so high. See atomic bombings of Hiroshima and Nagasaki. Examples of effects include: -Death -Cancer -Disintegration -Charring of the body -Vaporization (MORE)
to help save American lives and 2 end the war because if they didnt the war would have been 8 monthes longer
People not killed outright got injured with deep burns, as well ascuts and bruises. Later on rain fell and it was radioactive.Radiation caused vomiting, nausia, headache, and a loss of whiteblood cells.
There was a mixed reaction At the time it happened however people every where were happy as it signified the end of WW2.
Yes, but currently only as threats. They have not been used in war since the 2 used to end WW2.
Well, figure it out, they destroyed two cities, Hiroshima and the other Japanese city, I don't know the name of it, they all sound the same to a man with a PHD
During the occupation of Japan, following WWII, US military intelligence officers discovered several Japanese "Cyclotrons" (used during atomic research); photographs were taken (which were later published), and the devices along with all other nuclear research material were quickly dumped into the o…cean.. Note-Some of the photographs were taken, as the devices were being thrown into the ocean. (MORE)
Before the very scientifically complex atomic bomb, other bombs are just basically tons of explosive stuff jammed into a bombshell, so it wasn't too advanced there.
its a bomb that's atomic =) and blows up stuff. hope that helps first of all its what DO people think of the atomic bomb ^-^ any ways the atomic bomb astonished everyone (exept scientists) it very amazing >.
The Germans (luckily) never actually had a serious atomic bombproject. They were working on one in 1939 and 1940 but made anarithmetic error that suggested that >1000kg of enriched uraniumwould be needed per bomb (instead of the correct value of
The US wanted to develop a weapon before the Germans did, and fortunately had the scientists and resources to build one. Many key individuals came from European countries impacted by the war. In 1939, just before World War II, physicists including Albert Einstein had written a letter to President F…ranklin D. Roosevelt about the possibilities of a "bomb" releasing fission energy from a critical mass of uranium. After the war broke out, FDR became concerned about the possibility that Germany could develop such a bomb, and in 1941 created the OSRD (Office of Scientific Research and Development) to investigate further. By 1942, the far-flung efforts were placed under the military command known collectively as the Manhattan Project. (MORE)
It was decided to build them to protect against Germany building and using them. It was decided to use them on Japan to end the war ASAP and save lives.
On August 6, 1945, the first Atomic bomb was dropped on japan.Another was dropped on August 9,1945 which ended WWII. Those arethe only times in the history of warfare that an Atomic weapon wasused.
The atomic bomb helped peopole know more about radiation poisining and helped in the advancements in neuclear energy.
The decision to use the atomic bomb was made by President Truman. There was never any doubt of that and despite the rising tide of criticism Mr. Truman took full responsibility for his action. Only recently succeeded to the Presidency after the death of Roosevelt and beset by a multitude of problems… of enormous significance for the postwar world, Mr. Truman leaned heavily on the advice of his senior and most trusted advisers on the question of the bomb. But the final decision was his and his alone. Historians have found that there were likely several major reasons why Truman chose to use the atomic bomb (listed below in order of most important to least important): . The Iwo Jima and Okinawa campaigns had proved to be considerably more expensive (in terms of casualties) than prior invasions in the war, and were taken as a sign of the type of resistance that could be expected during the planned invasion of the Japanese Home Islands (Japan proper). Allied planners were predicting a 9 month to 1 year campaign necessary to completely eliminate all Japanese resistance, and casualty (dead, wounded, missing) estimates were 1 million Allied and as many as 10 million Japanese. The atomic bomb offered a quick and (for the U.S.) painless way to win. . The potential post-WW2 conflict between the U.S.S.R. and U.S.A. was already taking form. The U.S.S.R. had just declared war on Japan, and it was looking like they might be able to launch some sort of invasion of the Northern Japanese islands about the same time the U.S. invaded the Southern islands. Thus, any Japanese peace would have required a partitioned Japan (like Germany had been partitioned). So, the quicker the Japanese surrendered, the less influence the U.S.S.R. could claim in Asia. . As a corollary to #2, the atomic bomb would also make a huge geopolitical statement about the overwhelming superiority of the U.S. military, which would be a major benefit in the post-war geopolitical situation; in particular, it was seen as a method to discourage further Soviet expansion and influence. . A significant amount of institutional inertia around such a huge project. The Manhattan Project was by far the most expensive war program undertaken, and, when combined with the associated B-29 program, represented over 1% of the total war weaponry expenditures. To spend that sort of money, and get a successful weapon from it, then NOT to use it would be unthinkable. . A non-trivial amount of "revenge" mentality against the Japanese, as payback for Pearl Harbor and the atrocities that had occurred during the war. In addition, the Japanese were seen in many ways as sub-human, and deserving of any punishment we could met out. (MORE)
Atomic bombs were used by the US against Japan at the end of World War II. Once nuclear physicists and military leaders became aware of the application of nuclear fission for a weapon, it was decided to build atomic bombs, if only to counteract their development by Germany and the Axis. As things t…urned out, the Germans developed rockets, but never built a nuclear bomb for use with them. By the time the US had its bomb (July 16, 1945), Germany had been defeated without it, and it was used instead as intimidation against the last struggling war efforts of the Japanese. Rather than invade Japan, the US dropped two atomic bombs on Japanese cities, and implied that they had many more to use (in fact, they had no more, and could only build about two a month). With Japan's anti-invasion plans rendered useless, the Japanese surrendered six days after the second bomb was dropped (Hiroshima on August 6, and Nagasaki on August 9, 1945). (MORE)
When the atomic bomb was finished, Leo Szilard, a scientist in on the Manhattan Project (the Manhattan Project was the code name for the project to build and develop the atomic bomb), made a petition urging the President not to resort the use of atomic bombs in the war unless the news of the bomb ha…d been made open in public and on terms that Japan knows and refuses to surrender. The petition was signed by over 150 scientists in on the project. A counterpetition garners only two signatures. Japan, of course, refused to surrender. The result was the flattening of two major cities in Japan. (MORE)
it depends most people did actually die from being melted due to the heat of the bomb . Peace out . Most people did not "melt" the inital blast killed many, and the burning caused by the heat killed many more, people do not "melt" as there chemical composistions are very complex making it almost i…mpossible to melt people. Most people died from the significant radiation produced from the explosion of the Uranium when it reached its critical mass. (MORE)

The only time the US ever used Atomic Bombs was during World War 2 when the first atomic bombs were used. Nowadays, the atomic bombs are kept underground. Nuclear missiles are ready to use in the case of a nuclear warhead being launched at the US by an enemy or unknown foe. There have been thousands… of nuclear warheads disabled since the Cold War ended. (MORE)
Fissionable material sufficient to fission if it comes together, a lab safe enough to handle such material, and mechanisms sufficient to bring the pieces of fissionable material together in what is called "critical mass". Bare bones, you'd have a very large - and hard to transport - atomic bomb, of… WWII size. If you are wondering - given how easy that would be nowadays - why everyone doesn't have one, it's due to them being valueless without proper means of delivery. Which means they have to be small and yet still powerful, and be mounted on a very long range missile with a sophisticated guidance system. (MORE)
To make a fission atomic bomb you just take either uranium or plutonium, which are fast-fission materials and find a way to smash the soul out of them so they can make neutrons to continue the chain reaction. You either just take some fissionable uranium, make a bullet out of one and a ball of the o…ther, build a cannon-shaped bomb that shoots the bullet of uranium into the ball of uranium at the end of the barrel - and boom. To make the second kind, you need some plutonium. Plutonium is easy to obtain but it is extremely hard to make into a bomb, because if you shoot two masses of plutonium together like the uranium bomb style, they fission so much easier that they start reacting before they touch and blow themselves apart before anything can fission, so you will need to make a ball of plutonium crush in itself using a shock wave made by a explosion. You surround a ball of fissionable plutonium with explosive stuff. When the surrounding explosives goes boom, the shock waves made by the explosives hits the ball. This causes the plutonium to supercompress itself together - and boom. (MORE)
At the end of World War II, few questioned Truman's decision to drop the atomic bombs on Hiroshima and Nagasaki. Most Americans accepted the obvious reasoning: the atomic bombings brought the war to a more timely end. They did not have a problem with over one hundred thousand of the enemy being kill…ed. After all, the Japanese attacked America, and not the other way around. In later years, however, many have begun to question the conventional wisdom of "Truman was saving lives," putting forth theories of their own. However, when one examines the issue with great attention to the results of the atomic bombings and compares these results with possible alternatives to using said bombs, the line between truth and fiction begins to clear. Truman's decision to use the atomic bomb on Japan was for the purpose of saving lives and ending the war quickly in order to prevent a disastrous land invasion. (MORE)
The United States was faced with the daunting prospect of invading Japan in order to force a close to World War 2. The Japanese had already shown a willingness to go to incredible lengths to continue the war and to cause destruction to their enemies. The fierce fighting for islands near the Japanese… mainland (Iwo Jima and Okinawa) resulted in a staggering loss of 19,800 American dead and 58,000 wounded. Leaders knew that the losses in undertaking any invasion of the home islands would result in many, many more casualties. Some estimated that American casualties would reach 750,000 in invading Japan. Japanese civilian casualties were not a tremendous concern for American leaders at that time, but they were aware of the huge wave of suicides on Okinawa and of the 100,000+ death toll from the bombing and fires in Tokyo. In this method of calculating, the atomic bombs (if they worked as planned) would actually save lives: hundreds of thousands of American soldiers and sailors, and likely more than a million fewer Japanese civilian deaths. Another viewpoint is that the use of the bomb to shorten the war was essential economically. Four years of war had seriously strained America's finances. The government was not able to borrow any more money. The Treasury was in a panic. If the bomb was able to end the war, the risk of federal bankruptcy would be averted. The economic crisis was suppressed during the war and easy to ignore in history, but was very real at the time. (MORE)
Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. In general, large buildings are destroyed by the change in air pressure, while people and objects such as t…rees and utility poles are destroyed by the wind. Approximately 35 percent of the energy from a nuclear explosion is an intense burst of thermal radiation, i.e., heat. The effects are similar to the effect of a two-second flash from an enormous sunlamp. Since the thermal radiation travels at roughly the speed of light, the flash of light and heat precedes the blast wave by several seconds, just as lightning is seen before thunder is heard. (MORE)
WWII was a very difficult time; Americans and Australian's were badly mistreated, used as slaves (having to build the 'Death Railway' which the Japanese needed to transport supplies is a good example) and Stalags were not places that you could feel safe from being away from the Russian Front. Infact…, they were probably just as bad as each other. WWII ran from 1939-1945, started by Hitler's need for more land for Germany. Hitler became the fÃ¼hrer (Meaning leader) on August 2 1934. Of course WWII was a very complicated war, so explaining everything in detail would take too long to write. Therefore, we have posted a web address with a very good timeline and a short summary of key events below. New weapons were constanly being made, which led to the invention of the atomic bomb in 1945. The atomic bomb by the name of 'Little Boy' hit the Japanese city of Hiroshima on August 6 1945. An enormous cloud rose into the air about 9,900 metres high. 70,00 people died, 70,00 people were seriously injured and thousands more were efected in the years afterwards. Japan surrendered a couple of days later, officially ending the war. The atomic bomb was extremely powerful, so this was why it was used. It was also used because it was something the world had never seen before, therefore, it was the perfect weapon to decrease morale (spirit and hope) leading to Japan's surrender. (MORE)
1938 so we "pursueded" German scientists to come to our side and started the Manhattan project.
-Reasons to use the Atomic Bomb. Saves lives Saves money Saves time Revenge of Pearl Harbor Keep Russians out of Japan, preventing them from getting Manchuria.
Materials Needed Materials needed to make an atomic bomb are: fissionable material (Plutonium239 isotope) explosive to start the nuclear chain reaction (TNT, Gelignite or semtex) detonator pusher (made from aluminium, beryllium)
Between 11 and 23 American prisoners of war held in Hiroshima died when the atomic bomb was dropped on that city, along with more than 1000 Japanese- Americans that were unable to return to America due to the war. An unknown number of other American prisoners died at Nagasaki.
The first atomic bomb was dropped on Hiroshima, Japan ; another on Nagasaki, Japan, 3 days later.
Making the bombshell was easy, but the challenge was getting the right type of fissionable material, which was uranium and plutonium. Another big one was on how to trigger the chain reaction in time so it will not pulverize itself if it fissions too slow, nor blow up the bomb plane carrying it in mi…dair if the fission chain is too fast. (MORE)
Unsure of your term "inputs". To construct a nuclear weapon, it requires a source of scarce fissionable materials, such as Uranium 235, or Plutonium. It requires the ability to perform precision machining of these VERY difficult to work with materials. It requires the use of precisely shaped high ex…plosives of assorted types, the use of extremely high precision electronic timing equipment used to detonate the high explosive trigger, and a source of metals for a neutron donor ( such as beryllium) and the ability to machine that. Along the way, it is good not to die from handling and machining the metals. You also need a way to deliver a very heavy package- the original atomic bombs weighed 9000 to 10,000 lbs. (MORE)
World War II was a very desperate struggle, and it was considered to be necessary to build the most powerful weapons possible, in order to ensure victory. There was also no way of knowing if the enemy was also working on an atomic bomb (or other terrible weapons), so it was better to be the first …one to build it and to be able to win before the enemy came up with their own secret weapon. There was more to it than this. Fission was discovered in Germany in Dec. 1938 and the Nazis had the first government program to develop a bomb. Although many of their top physicists had been forced out, they still had plenty left including Nobel prize winner Warner Heisenberg, who headed the nuclear program. The U.S. had good reason to fear that Hitler would have the bomb before anyone else. They were far ahead in jet aircraft and rockets, yet never came close to exploding an atomic bomb. (MORE)
People feared it. some thought U.S.A. could control the world and that's what started the cold war.
The US has used atomic weapons in war twice, August 1945, Hiroshima Japan and Nagasaki Japan.
so if some other country nukes us we can nuke them and us having the biggest bombs is intimadating to other countries with nukes
The U.S. originally built the atomic bomb to end WW2 because it was the only alternative to invading Japan, which would have cost many, many more lives and been worse for all involved. Now atomic bombs are used for a balance of power - "If you nuke us we'll nuke you back" is enough to stop a few war…s. (MORE)
Leo Szilard, the inventor of the atomic bomb (patent GB630726), did not build it himself. He wrote a letter that he had Albert Einstein sign and send to president FDR warning of the potential of atomic bombs and that the Nazis were probably working on them already. If the Nazis got atomic bombs fi…rst the Allied cause was lost. FDR authorized funds for a study, the study recommended a full program be begun under direction of the Army. This program became the Manhattan Project, which built the bomb. Leo Szilard was one of hundreds of scientists employed by the Manhattan Project during WW2. (MORE)
It took the US 2 to 3 years to build the industrial infrastructure needed to begin building Atomic fission bombs. When the US first started building bombs in those factories in 1945 they could build 3 bombs a month with the expectation by the end of the year of building 7 a month. You compute the… time per bomb. But remember this is just beginning production, with each bomb hand assembled. These bombs were delivered by the factory to the field as a kit of parts in multiple crates. Assembly of a MK-III Fatman type bomb from this kit took 3 days in the field. At the peak of production both the US & USSR had the capacity to build 100s of Hydrogen fusion bombs per day! You compute the time per bomb. This was full assembly line production. These bombs were delivered by the factory to the field fully assembled and ready for use. (MORE)
The administrator of the Manhattan Project was Edward Teller. The lead scientist was J. Robert Oppenheimer.
Had we not developed the atom bomb, someone else would have. It's only natural for mankind to exploit our technology, and we were way ahead of the rest of the world. The atom bomb saved maybe a million lives in the Pacific War. Had it not been used there, it would have been used later by us, or the …Soviet Union, or the French. The use of it in Japan, due to it's horror, has been the biggest deterrent of use of atomic, or nuclear (hydrogen)weapons since. By ............... (MORE)
