A physicist is a scientist who specializes in the field of physics , which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena , and usually frame their understanding in mathematical terms. They work across a wide range of research fields , spanning all length scales: from sub-atomic and particle physics , through biological physics , to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena.
92-653: Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American physicist who received the Nobel Prize in Physics in 1923 for the measurement of the elementary charge and for his work on the photoelectric effect . Millikan graduated from Oberlin College in 1891 and obtained his doctorate at Columbia University in 1895. In 1896 he became an assistant at the University of Chicago , where he became

Wood recommended termination of Millikan's army commission, but a subsequent investigation by Frank McIntyre , the executive assistant to the army chief of staff, exonerated Millikan. He received the Chinese Order of Jade in 1940. After the War, Millikan contributed to the works of the League of Nations ' Committee on Intellectual Cooperation (from 1922, in replacement to George E. Hale , to 1931), with other prominent researchers ( Marie Curie , Albert Einstein , Hendrik Lorentz , etc.). Millikan

Franklin contends that Millikan's exclusions of data do not affect the final value of the charge obtained, but that Millikan's substantial "cosmetic surgery" reduced the statistical error. This enabled Millikan to give the charge of the electron to better than one-half of one percent. In fact, if Millikan had included all of
1288-583: A full professor in 1910. In 1909 Millikan began a series of experiments to determine the electric charge carried by a single electron. He began by measuring the course of charged water droplets in an electric field . The results suggested that the charge on the droplets is a multiple of the elementary electric charge, but the experiment was not accurate enough to be convincing. He obtained more precise results in 1910 with his oil-drop experiment in which he replaced water (which tended to evaporate too quickly) with oil . In 1914 Millikan took up with similar skill

Many colleges and universities and other institutions of higher learning throughout the world follow a similar hierarchical ranking structure amongst scholars in academia ; the list above provides details. A professor typically earns a base salary and a range of employee benefits . In addition, a professor who undertakes additional roles in their institution (e.g., department chair, dean, head of graduate studies, etc.) sometimes earns additional income. Some professors also earn additional income by moonlighting in other jobs, such as consulting , publishing academic or popular press books, giving speeches, or coaching executives. Some fields (e.g., business and computer science) give professors more opportunities for outside work. A report from 2005 by

While this would still have resulted in Millikan's having measured the charge of e better than anyone else at the time, the slightly larger uncertainty might have allowed more disagreement with his results within the physics community, which Millikan likely tried to avoid. David Goodstein argues that Millikan's statement, that all drops observed over

Repeating the experiment for many droplets, Millikan showed that the results could be explained as integer multiples of a common value (1.592 × 10 coulomb ), which is the charge of a single electron. That this is somewhat lower than the modern value of 1.602 176 53(14) x 10 coulomb is probably due to Millikan's use of an inaccurate value for the viscosity of air . Although at

6808-409: The study of " cosmic rays " (a term he coined). In the 1930s he entered into a debate with Arthur Compton over whether cosmic rays were composed of high-energy photons (Millikan's view) or charged particles (Compton's view). Millikan thought his cosmic ray photons were the "birth cries" of new atoms continually being created to counteract entropy and prevent the heat death of the universe . Compton
6900-486: The subject. [...] I doubt if I have ever taught better in my life than in my first course in physics in 1889. I was so intensely interested in keeping my knowledge ahead of that of the class that they may have caught some of my own interest and enthusiasm. Millikan's enthusiasm for education continued throughout his career, and he was the coauthor of a popular and influential series of introductory textbooks, which were ahead of their time in many ways. Compared to other books of
6992-425: The time of Millikan's oil-drop experiments it was becoming clear that there exist such things as subatomic particles, not everyone was convinced. Experimenting with cathode rays in 1897, J. J. Thomson had discovered negatively charged 'corpuscles', as he called them, with a charge-to-mass ratio 1840 times that of a hydrogen ion. Similar results had been found by George FitzGerald and Walter Kaufmann . Most of what
7084-454: The time, they treated the subject more in the way in which it was thought about by physicists. They also included many homework problems that asked conceptual questions, rather than simply requiring the student to plug numbers into a formula. 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 . J. J. Thomson had already discovered
7176-576: The title associate professor is used in place of the term reader as used in the United Kingdom and other Commonwealth countries; ranking above senior lecturer and below full professor. Beyond holding the proper academic title, universities in many countries also give notable artists, athletes and foreign dignitaries the title honorary professor , even if these persons do not have the academic qualifications typically necessary for professorship and they do not take up professorial duties. However, such "professors" usually do not undertake academic work for
7268-401: The title professor is the highest academic rank at a university. In the United States and Canada , the title of professor applies to most post-doctoral academics, so a larger percentage are thus designated. In these areas, professors are scholars with doctorate degrees (typically PhD degrees) or equivalent qualifications who teach in colleges and universities . An emeritus professor is
7360-485: The title is used in this sense in the United Kingdom (where it is known as a research professor at some universities and professorial research fellow at some other institutions) and in northern Europe . A research professor is usually the most senior rank of a research-focused career pathway in those countries and is regarded as equal to the ordinary full professor rank. Most often they are permanent employees, and
7452-517: The total number of sexenios is a prerequisite for being a member of different committees. The importance of these sexenios as a prestige factor in the university was enhanced by legislation in 2001 (LOU). Some indicative numbers can be interesting, in spite of the variance in the data. We report net monthly payments (after taxes and social security fees), without bonuses: Ayudante, €1,200; Ayudante Doctor, €1,400; Contratado Doctor; €1,800; Profesor Titular, €2,000; Catedrático, €2,400. There are
7544-580: The vast body of evidence that had already shown that light was a wave . He undertook a decade-long experimental program to test Einstein's theory, which required building what he described as "a machine shop in vacuo " in order to prepare the very clean metal surface of the photoelectrode. His results, published in 1914, confirmed Einstein's predictions in every detail, but Millikan was not convinced of Einstein's interpretation, and as late as 1916 he wrote, "Einstein's photoelectric equation... cannot in my judgment be looked upon at present as resting upon any sort of
7636-409: The whole of recorded history. If the rational, scientific, progressive principles win out in this struggle there is a possibility of a warless, golden age ahead for mankind. If the reactionary principles of despotism triumph now and in the future, the future history of mankind will repeat the sad story of war and oppression as in the past. Millikan died at a Pasadena nursing home in 1953 at age 85, and
7728-467: The word "professor" internationally, where the unqualified word "professor" only refers to full professors. The majority of university lecturers and instructors in the United States, as of 2015 , do not occupy these tenure-track ranks, but are part-time adjuncts. In 2007 the Dutch social fund for the academic sector SoFoKleS commissioned a comparative study of the wage structure of academic professions in
7820-403: Was a member of the organizing committee of the 1932 Los Angeles Olympics , and in his private life was an enthusiastic tennis player. He was married and had three sons, the eldest of whom, Clark B. Millikan , became a prominent aerodynamic engineer. Another son, Glenn , also a physicist, married the daughter (Clare) of George Leigh Mallory of "Because it's there" Mount Everest fame. Glenn
7912-537: Was born on March 22, 1868, in Morrison, Illinois . He went to high school in Maquoketa, Iowa and received a bachelor's degree in the classics from Oberlin College in 1891 and his doctorate in physics from Columbia University in 1895 – he was the first to earn a Ph.D. from that department. At the close of my sophomore year [...] my Greek professor [...] asked me to teach the course in elementary physics in
8004-746: Was coined by William Whewell (also the originator of the term "scientist") in his 1840 book The Philosophy of the Inductive Sciences . A standard undergraduate physics curriculum consists of classical mechanics , electricity and magnetism , non-relativistic quantum mechanics , optics , statistical mechanics and thermodynamics , and laboratory experience. Physics students also need training in mathematics ( calculus , differential equations , linear algebra , complex analysis , etc.), and in computer science . Any physics-oriented career position requires at least an undergraduate degree in physics or applied physics, while career options widen with
8096-606: Was eventually proven right by the observation that cosmic rays are deflected by the Earth's magnetic field (hence must be charged particles). Millikan was Vice Chairman of the National Research Council during World War I . During that time, he helped to develop anti-submarine and meteorological devices. During his wartime service, an investigation by Inspector General William T. Wood determined that Millikan had attempted to steal another inventor's design for
8188-452: Was first used in the late 14th century to mean 'one who teaches a branch of knowledge'. The word comes "...from Old French professeur (14c.) and directly from [the] Latin professor [, for] 'person who professes to be an expert in some art or science; teacher of highest rank ' "; the Latin term came from the "... agent noun from profiteri 'lay claim to, declare openly ' ". As
8280-603: Was interred in the "Court of Honor" at Forest Lawn Memorial Park Cemetery in Glendale, California . On January 26, 1982, he was honored by the United States Postal Service with a 37¢ Great Americans series (1980–2000) postage stamp . Tektronix named a street on their Portland, Oregon , campus after Millikan with the Millikan Way (MAX station) of Portland 's MAX Blue Line named after
8372-574: Was killed in a climbing accident in Cumberland Mountains in 1947. In the aftermath of the 1933 Long Beach earthquake , Millikan chaired the Joint Technical Committee on Earthquake Protection. They authored a report proposing means to minimize life and property loss in future earthquakes by advocating stricter building codes. A religious man and the son of a minister, in his later life Millikan argued strongly for
8464-435: Was then known about electricity and magnetism could be explained on the basis that charge is a continuous variable. This in much the same way that many of the properties of light can be explained by treating it as a continuous wave rather than as a stream of photons. The beauty of the oil-drop experiment is that as well as allowing quite accurate determination of the fundamental unit of charge, Millikan's apparatus also provided
