Please answer this: Information: - Natural science is a branch of science concerned with the description, prediction, and understanding of natural phenomena, based on observational and empirical evidence. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances. - The University of California (UC) is a public university system in the U.S. state of California. Under the California Master Plan for Higher Education, the University of California is a part of the state's three-system public higher education plan, which also include the California State University system and the California Community Colleges System. - In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F. - In physics, energy is the property that must be transferred to an object in order to perform work on or to heat the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. - An Emmy Award, or simply Emmy, recognizes excellence in the television industry, and corresponds to the Academy Award (for film), the Tony Award (for theatre), and the Grammy Award (for music). - The University of California, Berkeley, (also referred to as Berkeley, UC Berkeley, and Cal) is a public research university located in Berkeley, California. Founded in 1868, Berkeley is the oldest of the ten research universities affiliated with the University of California system, and is often cited as the top public university in the United States and around the world. - Geoffrey Foucar Chew (born June 5, 1924) is an American theoretical physicist. - In the classical physics observed in everyday life, if something has mass and takes up space, it is said to be composed of matter; this includes atoms (and thus molecules) and anything made up of these, but not other energy phenomena or waves such as light or sound. More generally, however, in (modern) physics, matter is not a fundamental concept because a universal definition of it is elusive: elementary constituents of atoms may not take up space individually, and massless particles may be composed to form objects that have mass (even when at rest). - Physics (from , from "phusis" "nature") is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves. - The Antoinette Perry Award for Excellence in Theatre, more commonly known as the Tony Award, recognizes achievement in live Broadway theatre. The awards are presented by the American Theatre Wing and The Broadway League at an annual ceremony in New York City. The awards are given for Broadway productions and performances, and an award is given for regional theatre. Several discretionary non-competitive awards are also given, including a Special Tony Award, the Tony Honors for Excellence in Theatre, and the Isabelle Stevenson Award. The awards are named after Antoinette "Tony" Perry, co-founder of the American Theatre Wing. - A Grammy Award (originally called Gramophone Award), or Grammy, is an honor awarded by The Recording Academy to recognize outstanding achievement in the mainly English-language music industry. The annual presentation ceremony features performances by prominent artists, and the presentation of those awards that have a more popular interest. It shares recognition of the music industry as that of the other performance awards such as the Emmy Awards (television), the Tony Awards (stage performance), and the Academy Awards (motion pictures). - John Robert Taylor is an emeritus professor of physics at the University of Colorado , Boulder . He received his B.A. in mathematics at Cambridge University , and his Ph.D. from the University of California , Berkeley in 1963 with thesis advisor Geoffrey Chew . Taylor has written several college - level physics textbooks . His bestselling book is An Introduction to Error Analysis , which has been translated into six languages . Taylor was designated a Presidential Teaching Scholar in 1991 . He has also received an Emmy Award for his television series Physics 4 Fun ( 1988 -- 1990 ) .

Q: Information: - A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936. In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards which contain a written indication of the plot or key dialogue. The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was only made practical in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system. During silent films, a pianist, theatre organist, or, in large cities, even a small orchestra would often play music to accompany the films. Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music. - Chicago is a 1927 comedy - drama silent film produced by Cecil B. DeMille and directed by Frank Urson . - Frank John Urson (March 21, 1887 August 17, 1928) was an American silent film director and cinematographer from Chicago, Illinois. Originally a photographer, he moved on to cinematography and film directing for the Thanhouser Company in New Rochelle, New York. He is also credited with acting in one film "Her Gallant Knights" which starred William Garwood in 1913. Urson directed "Changing Husbands". He is perhaps best known for his 1927 "Chicago", produced by Cecil B. DeMille. - The Thanhouser Company (later the Thanhouser Film Corporation) was one of the first motion picture studios, founded in 1909 by Edwin Thanhouser, his wife Gertrude and his brother-in-law Lloyd Lonergan. It operated in New York City until 1918, producing over a thousand films. - A pianist is an individual musician who plays the piano. Most forms of Western music can make use of the piano. Consequently, pianists have a wide variety of repertoire and styles to choose from, including traditionally classical music, Jazz, blues and all sorts of popular music, including rock music. Most pianists can, to a certain extent, play other keyboard-related instruments such as the synthesizer, harpsichord, celesta and the organ and keyboard. Perhaps the greatest pianist of all time was Franz Liszt, whose piano mastery was described by Anton Rubinstein: "In comparison with Liszt, all other pianists are children". - Her Gallant Knights is a 1913 American silent short romantic comedy film starring William Garwood, Riley Chamberlin, James Cruze, Florence La Badie and Frank Urson. - Changing Husbands is a 1924 American silent comedy starring Leatrice Joy, and Victor Varconi, directed by Paul Iribe and Frank Urson and written by Sada Cowan and Howard Higgin. The runtime is 70 minutes. It is preserved in the Library of Congress collection. What entity does 'chicago ' has the relation 'director' with?
