In the month of August in 1945 atomic explosions devastated Hiroshima and Nagasaki, killing over 1,50,000 people. The first atomic explosion was triggered on 6th August and second on
9th August 1945. The followings are important aspects of formation and explosion of Atomic Bomb.(i) On 12 September 1932, when Leo Szilard (just seven months AFTER discovery of Neutron, and six years BEFORE discovery of fission), suggested the possibility of 'Chain Reaction ', in ENGLAND. But this proposal was rejected by Ernest Rutherford immediately.
(ii) On 2 Septemebr 1939 , Hahn and Strassmann, the bombardment of uranium with neutrons had split the uranium atom almost in half , and huge amount of energy was liberated. Thus nuclear fission was discovered, it was perceived by Slizard.
(iii) 2 August 1939, Einstein signed letter (prepared by Leo Szilard) to American President Franklin Roosevelt about the possibility formation of Atom Bomb. This letter was delivered to President Roosevelt on 1 Sep 1939 and on 11th October 6000USD were sanctioned to by graphite and uranium as proposed by Szilard.
(vi) This project was known as Manhattan project. It has mainly 13 scientists and Einstein was associated with formation of Atom Bomb at all. The total expenditure on the project in six year was about 2 billion.
(vii) On 2 Dec. 1945 at 3.30 pm, American-Italian Enricho Fermi started first sustained Chain Reaction in Chicago, USA. It was perceived by Slizard long time back.
(vi) On July 16, 1945, this atomic explosion was tested by the US administration in New Mexico. Many scientists appealed that this weapon must not be used.
(vii) On 6th August 1945 American Bomber B52 dropped bomb at 11:02 local time and it exploded 500m in air in Hiroshima. This explosion generated energy equivalent to 15-kiloton TNT explosion. The second explosion took place on 9th August at Nagasaki.
These explosions killed more than 1, 50,000 people. It is so nice that in past 62 there no such devastating incidence in world and hope it will never happen AGAIN..
