Millikan’s experiments on the single electron carrying an electric charge began in 1909. The first experiment he’s doing was to measure the electric charge in charged water drops. Although the results indicated that water droplets have a charge multiple of an elementary electric charge however, the result was not convincing. He obtained more precise results in 1910 with his famous oil-drop experiment in which he replaced water (which tended to evaporate too quickly) with oil 😁 Millikan varied the electric voltage between two metal plates as an oil drop fell between them until the drop stopped falling 🙈 When the drop was stationary, the downward force of gravity on the drop equaled the upward electrical force on the charges in the drop, and then Millikan could measure how much charge the drop had had 🙈
Robert Andrews Millikan was the second child of Mary Jane Andrews Andrews (Reverend Silas Franklin Millikan) and was born 22 March 1868 in Morrison, Illinois. His grandparents belonged to the Old New England heritage, which arrived in America prior 1750. They were pioneer settlers in Middle West. As a child, he lived in the countryside and attended Maquoketa High School (Iowa). He was able to leave the Maquoketa High School (Iowa) after his graduation. Working for a short He worked as a court reporter and was admitted to Oberlin College in Ohio (Ohio), 1886. He loved mathematics and Greek during his undergraduate studies. But, after graduating from Oberlin College in 1891, his passions changed to elementary physics teaching. It was in this period that he developed His interest in the subject that would later lead to him becoming a great scientist. He’s was making Fellow at Columbia University in Physics in 1893 after having earned his mastership. He afterwards received his Ph.D. (1895) for research on the polarization of light emitted by incandescent surfaces – using for this purpose molten gold and silver at the U.S. Mint.

Robert Millikan, a physicist, discovered the electron’s elementary charge using an oil-drop experiment. He placed drops of oil between two electrodes. Then, he used mechanical equilibrium and the gravitational forces to balance the charges. He also designed an experiment to verify Einstein’s equation for the photoelectric effect and found Einstein’s prediction about the linearity between energy frequency are correct. Millikan won the Nobel Prize in Physics in Physics in 1923 for his contributions to the elementary charge of electricity, and the photoelectric effect.
Robert Andrews Millikan was a Morrison, Illinois (USA), native on March 22, 1868. He graduated from Oberlin College, Ohio (1891), where he enjoyed mathematics and Greek. After that, he’s taking two classes in elementary physics which rekindled his interest in the discipline. He was granted a Columbia University fellowship in 1893. In 1895, he earned his PhD for his thesis about the polarization light that is emitted from incandescent surfaces. A phenomenon that had originally been observed (1824) by François Aragó, Millikan used molten gold and silver from the US Department of Treasury to prove his thesis. After spending a year (1896) in Germany at the Universities of Berlin and Götingen, he return to the United States To accept an invitation by Albert A. Michelson, physicist and Nobel Laureate, to be his assistant at the newly founded Ryerson Laboratory at Chicago. Millikan was to eventually become a lecturer at the University of Chicago (1910). This post he’s holding for almost a century. Millikan died in 1953. Modified by Kyley W. On February 4, 2020
His classic oil drop experiment, which accurately determined the electron’s charge, is a highlight of his fame. He was awarded the Nobel Prize in Physics in Physics in 1923 for his photoelectric effects research. Interestingly, Millikan’s research achievements promoted the general acceptance of both Niels Bohr’s quantum theory of the atom and Albert Einstein’s photoelectric equation, an important step precipitating their recognition by the Nobel Foundation in 1922 and 1921, respectively, and, more importantly, placing modern physics on a firm foundation. Millikan was a pioneer in the development of modern physics during the second half of his life. Establishing the California Institute of Technology, a leading research organisation.
