The discovery of his law of motion of a particle falling towards the earth after entering the earths atmosphere, together with his other investigations on electrical phenomena, ultimately led him to his significant studies of cosmic radiation (particularly with ionization chambers). His grandparents were of the Old New England stock which had come to America before 1750, and were pioneer settlers in the Middle West. Another example is that his textbook, as late as the 1927 version, unambiguously states the existence of the ether, and mentions Einstein's theory of relativity only in a noncommittal note at the end of the caption under Einstein's portrait, stating as the last in a list of accomplishments that he was "author of the special theory of relativity in 1905 and of the general theory of relativity in 1914, both of which have had great success in explaining otherwise unexplained phenomena and in predicting new ones. Starting in 1908, while a professor at the University of Chicago, Millikan worked on an oil-drop experiment in which he measured the charge on a single electron.

The second son of a Congregational minister of Scotch-Irish ancestry, R. A. Millikan was born on March 22, 1868. Professor Millikan has been President of the American Physical Society, Vice-President of the American Association for the Advancement of Science, and was the American member of the Committee on Intellectual Cooperation of the League of Nations, and the American representative at the International Congress of Physics, known as the Solvay Congress, at Brussels in 1921. His experiment measured the force on tiny charged droplets of oil suspended against gravity between two metal electrodes. In his 1950 autobiography, however, he simply declared that his work "scarcely permits of any other interpretation than that which Einstein had originally suggested, namely that of the semi-corpuscular or photon theory of light itself". In the 18th century, it was very difficult to secure public funding for the sciences from the government. At the age of 26, Lavoisier bought shares at Ferme gnrale, an outsourced tax collector on behalf of the king. Get to know these pioneers who went down in history for their groundbreaking work, including scientists behind common terms such as Amp, Celsius, Kelvin, hertz and tesla. There he undertook a major study of the radiation that the physicist Victor Hess had detected coming from outer space. Millikan proved that this radiation is indeed of extraterrestrial origin, and he named it cosmic rays. As chairman of the executive council of Caltech from 1921 until his retirement in 1945, Millikan turned that school into one of the leading research institutions in the United States. 0.678. They authored a report proposing means to minimize life and property loss in future earthquakes by advocating stricter building codes.

He is particularly well known for his highly accurate determination of the charge of an electron via his classic oil drop experiment. Heisenberg passed away in his home on February 1, 1976, after suffering from kidney cancer. To my reply that I did not know any physics at all, his answer was, "Anyone who can do well in my Greek can teach physics." At this moment, August 22, 1938, the principles of representative ballot government, such as are represented by the governments of the Anglo-Saxon, French, and Scandinavian countries, are in deadly conflict with the principles of despotism, which up to two centuries ago had controlled the destiny of man throughout practically the whole of recorded history. That this is somewhat lower than the modern value of 1.602 176 53(14) x 1019 coulomb is probably due to Millikan's use of an inaccurate value for the viscosity of air.[15][16].
