Notes on the history of the atom In 1897 the British physicist Joseph John (J. J.) Thomson (1856–1940) discovered the electron in a series of experiments designed to study the nature of electric discharge in a high-vacuum cathode-ray tube‚ an area being investigated by numerous scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets as evidence of &quotbodies much smaller than atoms&quot that he calculated as having a very large value

The dropping of the atomic bombs on Hiroshima and Nagasaki remains among the most controversial events in modern history. Historians have actively debated whether the bombings were necessary. What effect they had on bringing the war in the Pacific to an end and what other options were available to the United States. As American policymakers struggled with how to use a powerful new technology and what the long-term impact of atomic weaponry might be‚ not just on the Japanese but on domestic politics
