Robert Andrews Millikan

Robert Andrews Millikan was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric 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 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 famous oil-drop experiment in which he replaced water with oil. In 1914 Millikan took up with similar skill the experimental verification of the equation introduced by Albert Einstein in 1905 to describe the photoelectric effect.

He used this same research to obtain an accurate value of Planck’s constant. In 1921 Millikan left the University of Chicago to become director of the Norman Bridge Laboratory of Physics at the California Institute of Technology in Pasadena, California. 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, he named it "cosmic rays." As chairman of the Executive Council of Caltech from 1921 until his retirement in 1945, Millikan helped to turn the school into one of the leading research institutions in the United States. He served on the board of trustees for Science Service, now known as Society for Science & the Public, from 1921 to 1953. Robert Andrews Millikan was born on March 1868, in Morrison, Illinois, he went to high school in Maquoketa 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 the preparatory department during the next year. 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." "All right," said I, "you will have to take the consequences, but I will try and see what I can do with it." I at once purchased an Avery's Elements of Physics, spent the greater part of my summer vacation of 1889 at home – trying to master the subject. I doubt if I have 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, 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 the time, they treated the subject more in the way in which it was thought about by physicists.

They included many homework problems that asked conceptual questions, rather than 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 discovered the charge-to-mass ratio of the electron. However, the actual charge and mass values were unknown. Therefore, if one of these two values were to be discovered, the other could be calculated. Millikan and his graduate student Harvey Fletcher used the oil-drop experiment to measure the charge of the electron. Professor Millikan took sole credit, in return for Harvey Fletcher claiming full authorship on a related result for his dissertation. Millikan went on to win the 1923 Nobel Prize for Physics, in part for this work, Fletcher kept the agreement a secret until his death. After a publication on his first results in 1910, contradictory observations by Felix Ehrenhaft started a controversy between the two physicists.

After improving his setup, Millikan published his seminal study in 1913. The elementary charge is one of the fundamental physical constants, accurate knowledge of its value is of great importance, his experiment measured the force on tiny charged droplets of oil suspended against gravity between two metal electrodes. Knowing the electric field, the charge on the droplet could be determined. Repeating the experiment for many droplets, Millikan showed that the results could be explained as integer multiples of a common value, the charge of a single electron; that this is somewhat lower than the modern value of 1.602 176 53 x 10−19 coulomb is due to Millikan's use of an inaccurate value for the viscosity of air. Although at 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 Walter Kaufmann. Most of what was known about electricity and magnetism, could be explained on the basis that charge is a continuous variable.

Jerry Donahue

Jerry Donahue is an American guitarist and producer known for his work in the British folk rock scene as a member of Fotheringay and Fairport Convention as well as being a member of the rock guitar trio The Hellecasters. Donahue was born in New York, the son of big band saxophonist Sam Donahue and actress Patricia Donahue and grew up in Los Angeles. Encouraged by his parents, Donahue took classical guitar lessons as a child, but it was Gerry McGee who made the biggest impression on him, when the 14-year-old Donahue witnessed him playing a behind-the-nut bend at a performance at the Sea Witch, emulating Earl Scruggs' banjo technique. Donahue took lessons from McGee. Regarding regular bends on the fretboard, Donahue cites Amos Garrett as a major influence. Other influences in his formative years were Duane Eddy, The Shadows and The Ventures. After moving to England, Donahue soon became a respected member of the developing British folk rock scene; as a band member, he played with Poet and the One Man Band and Fairport Convention.

He recorded and/or toured with artists such as Joan Armatrading, Gerry Rafferty, Robert Plant, Elton John, The Proclaimers, Mick Greenwood, Johnny Hallyday, Gary Wright, Cliff Richard, Chris Rea, Warren Zevon, Bonnie Raitt, Hank Marvin, Roy Orbison, Nanci Griffith, The Beach Boys and The Yardbirds. In 1990 he founded the guitar trio The Hellecasters with John Jorgenson, they recorded several instrumental albums and toured in the 1990s and early 2000s. Donahue has released instructional videotapes and more has produced solo projects including Sandy Denny's Gold Dust and The Animals' Instinct as well as finishing the second album by his short-lived Folk rock band Fotheringay in 2008. In 2009, Donahue formed the band Gathering – Legends of Folk Rock with Clive Bunker, Rick Kemp, Ray Jackson, Doug Morter and daughter Kristina Donahue. Jerry joined The Electric Revelators duo Gordon Wride & Simon Gregory in February 2011 for a UK tour of The Songs Of Robert Johnson in celebration of the king of delta blues birth in 1911.

During this period The Electric Revelators featuring Jerry Donahue, Gordon Wride and Simon Gregory headlined the Acoustic Stage Colne Blues Festival August 2011, once again performing the songs of Robert Johnson – this was a one off festival appearance. On July 29, 2016, Donahue suffered a paralyzing stroke. According to reports published several weeks doctors told his family that he would never play the guitar again. Feeling at home in the US as well as in the UK, Donahue musically draws from influences of both countries like Celtic music, rock and country. Technically, Donahue plays in fingerpicking or hybrid picking style with his right hand. However, his left hand technique made him famous among guitar players: Since his first encounter with guitarists Gerry McGee and Amos Garrett as a teenager, Donahue was fascinated by and mastered the technique of string "bending" bending several strings at once and bending notes by pressing down the strings beyond the nut. Telecaster player Danny Gatton praised him as "the string-bending king of the planet".

Around 1997, Fender made a Jerry Donahue signature Stratocaster in Japan, but Donahue's style and technique are associated with his signature Fender Telecaster and the Telecaster in general. His signature Stratocaster was modified with a metal plate under the bridge pickup to more emulate the Telecaster sound; the JD Telecaster is noticeable for replacing the chrome Tele neck pickup with a Strat pickup and the addition of a 5-way switch with custom wiring. More Peavey released the Omniac JD signature guitar; the current guitar bearing the Jerry Donahue name is the Fret King Black Label Jerry Donahue model, designed by Jerry and the world-renowned guitar designer, Trev Wilkinson. Guitarist magazine in the UK have given this guitar the coveted Guitarist's Choice award with 4.5 stars out of 5. Still popular on the used music gear market is the Jerry Donahue signature Award-Session Sessionmaster Compact JD10 live/recording preamp pedal, made in England from 1979 to 2004; the JD10 offers a range of classic clean and overdrive tones with speaker emulation and acts as a line-driver/buffer.

Doug Otto

Douglas B. Otto is a business executive who co-founded Deckers Outdoor Corporation whose portfolio includes the UGG Australia brand. Otto was born in 1951 to two high school educators, he attended and graduated from the University of California, Santa Barbara with a B. A. in business economics in 1973. While at UCSB in 1973, Otto began producing sandals with classmate Karl F. Lopker; the duo, with Otto handling sales and distribution while Lopker oversaw manufacturing, based the company on durable, long-lasting sandals which catered to the surf community. After buying out Lopker in 1982, Otto decided to license and manufacture other companies' product which resulted in a 1985 agreement with Teva. Deckers in 1995 acquired UGG Australia; the move, engineered by Otto, has been described as a "... brilliant and lucrative business maneuver..." and "one of the great success stories within the consumer category." The UGG brand, with Deckers, gained market traction but after an Oprah Winfrey feature on a "Favorite Things show sales and popularity increased dramatically.

UGGs soon became a fashion trend ingrained in popular culture with celebrities such as Kate Moss, Katy Perry, Gisele Bündchen, Sarah Michelle Gellar all wearing the brand as well as being shown on Sex and the City. Otto retired from Deckers in 2008, but revenue continued to climb and first hit $1 billion US dollars in 2010. Doug Otto has three children, he is the President and Chairman of the Board for The Whale Beach Foundation, roles he has held since 1994. He was honored by UC Santa Barbara in 2009 with its "Distinguished Alumni" award, joining his Deckers Corporation co-founder Karl Lopker, a 1998 honoree. Bloomberg Businessweek executive biography
