Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena . This is in contrast to experimental physics , which uses experimental tools to probe these phenomena.
61-502: Yahoo Serious (born Greg Pead ; 27 July 1953) is an Australian actor. His films include the comedy films Young Einstein (1988), Reckless Kelly (1993), and Mr. Accident (2000). Serious writes, directs, produces, stars in, and has composed the scores for his movies. Serious, born Greg Gomez Pead, was born on 27 July 1953 in Cardiff, New South Wales . He attended Glendale East Public School and Cardiff High School, then worked as

R i c = k g {\displaystyle \mathrm {Ric} =kg} The equations for an Einstein manifold , used in general relativity to describe the curvature of spacetime A physical theory involves one or more relationships between various measurable quantities. Archimedes realized that
183-469: A "one-joke movie, and I didn't laugh much the first time." He postulated that the possible lack of appeal to an American audience was because "[b]y moving Einstein to Australia, he was able to set up comic situations that appeal to the vast and inexhaustible fascination the Australians have about their own isolation and gawky charm. But the jokes don't travel very well." He gave the film one star out of
244-404: A certain economy and elegance (compare to mathematical beauty ), a notion sometimes called " Occam's razor " after the 13th-century English philosopher William of Occam (or Ockham), in which the simpler of two theories that describe the same matter just as adequately is preferred (but conceptual simplicity may mean mathematical complexity). They are also more likely to be accepted if they connect
305-500: A form of protoscience and others are a form of pseudoscience . The falsification of the original theory sometimes leads to reformulation of the theory. "Thought" experiments are situations created in one's mind, asking a question akin to "suppose you are in this situation, assuming such is true, what would follow?". They are usually created to investigate phenomena that are not readily experienced in every-day situations. Famous examples of such thought experiments are Schrödinger's cat ,
366-766: A good example. For instance: " phenomenologists " might employ ( semi- ) empirical formulas and heuristics to agree with experimental results, often without deep physical understanding . "Modelers" (also called "model-builders") often appear much like phenomenologists, but try to model speculative theories that have certain desirable features (rather than on experimental data), or apply the techniques of mathematical modeling to physics problems. Some attempt to create approximate theories, called effective theories , because fully developed theories may be regarded as unsolvable or too complicated . Other theorists may try to unify , formalise, reinterpret or generalise extant theories, or create completely new ones altogether. Sometimes
427-473: A humanitarian organisation focused on Papua New Guinea . In 2019, in a rare Q&A session at Sydney's Hayden Orpheum Picture Palace , Serious stated in response to a question about what he had been doing recently, “I have been writing and I hope to continue to make some more movies.” Serious received an honorary doctorate from the University of Newcastle in 1996. Serious was a guest celebrity for
488-658: A major marketing push. It continues to be regarded as a flop. It did, however, end its US theatrical run at a slightly profitable $ 11,536,599. The film has been released on DVD in region 1. The DVD is available in Australia by LA Entertainment. Theoretical physics The advancement of science generally depends on the interplay between experimental studies and theory . In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations. For example, while developing special relativity , Albert Einstein
549-552: A movie star in Hollywood . While Reckless Kelly was a hit in Australia, it failed outside of the country and ended Serious's bid for mainstream international popularity. In 2000, Serious released his third film, Mr. Accident , about the most accident-prone man in the world. Like Reckless Kelly , the film was not a commercial success outside Australia. Serious is a director of the Kokoda Track Foundation ,
610-498: A new branch of mathematics: infinite, orthogonal series . Modern theoretical physics attempts to unify theories and explain phenomena in further attempts to understand the Universe , from the cosmological to the elementary particle scale. Where experimentation cannot be done, theoretical physics still tries to advance through the use of mathematical models. Mainstream theories (sometimes referred to as central theories ) are
671-417: A pie." Neil Jillett of Australia's The Age reviewed the film positively, noting that despite some "directorial slackness", the film was "a lively work that is sophisticated and innocent, witty and farcical, satirical and unmalicious, intelligent but not condescending, full of concern with big issues but not arrogantly didactic, thoroughly Australian but not nationalistic." Variety meanwhile thought that

The reviewers at The Washington Post were unimpressed: Rita Kempley called the film "dumber-than-a-bowling-ball" and questioned its mass appeal; Desson Howe noted that distributor Warner Bros. had made it a "pre-processed legend" regardless of merit. The New York Times
793-443: A previous screenplay called The Great Galute which he had written with David Roach . It was a story about an Australian who invents rock and roll . The two developed The Great Galute into Young Einstein . The film was created on an extremely low budget, so low that Serious sold his car to generate funds, cameras were borrowed, and his mother cooked for the crew. Serious managed to get Australian Film Commission support for
854-498: A ship floats by displacing its mass of water, Pythagoras understood the relation between the length of a vibrating string and the musical tone it produces. Other examples include entropy as a measure of the uncertainty regarding the positions and motions of unseen particles and the quantum mechanical idea that ( action and) energy are not continuously variable. Theoretical physics consists of several different approaches. In this regard, theoretical particle physics forms

After being expelled from art school, Serious co-wrote, co-produced, edited and directed at age 21 his first film, Coaltown , "with the assistance of the Australian Film Institute ". Released in 1977, Coaltown explores the social and political history of coal mining . In 1988, Serious co-wrote, produced, directed, and played
976-469: A wide range of phenomena. Testing the consequences of a theory is part of the scientific method . Physical theories can be grouped into three categories: mainstream theories , proposed theories and fringe theories . Theoretical physics began at least 2,300 years ago, under the Pre-socratic philosophy , and continued by Plato and Aristotle , whose views held sway for a millennium. During
1037-505: Is a fantasized account of the life of Albert Einstein which alters all people, places and circumstances of his life, including relocating the theoretical physicist to Australia, having him splitting the atom with a chisel, and inventing rock and roll and surfing . Although highly successful in Australia, and winning an award from the Australian Film Institute Awards , it was poorly received by critics in
1098-497: Is a model of physical events. It is judged by the extent to which its predictions agree with empirical observations. The quality of a physical theory is also judged on its ability to make new predictions which can be verified by new observations. A physical theory differs from a mathematical theorem in that while both are based on some form of axioms , judgment of mathematical applicability is not based on agreement with any experimental results. A physical theory similarly differs from
1159-539: The EPR thought experiment , simple illustrations of time dilation , and so on. These usually lead to real experiments designed to verify that the conclusion (and therefore the assumptions) of the thought experiments are correct. The EPR thought experiment led to the Bell inequalities , which were then tested to various degrees of rigor , leading to the acceptance of the current formulation of quantum mechanics and probabilism as
1220-572: The Scientific Revolution gathered pace, the concepts of matter , energy, space, time and causality slowly began to acquire the form we know today, and other sciences spun off from the rubric of natural philosophy . Thus began the modern era of theory with the Copernican paradigm shift in astronomy, soon followed by Johannes Kepler 's expressions for planetary orbits, which summarized the meticulous observations of Tycho Brahe ;
1281-461: The two-fluid theory of electricity are two cases in this point. However, an exception to all the above is the wave–particle duality , a theory combining aspects of different, opposing models via the Bohr complementarity principle . Physical theories become accepted if they are able to make correct predictions and no (or few) incorrect ones. The theory should have, at least as a secondary objective,

#17328023475101342-429: The 19th century. Another important event in the 19th century was the discovery of electromagnetic theory , unifying the previously separate phenomena of electricity, magnetism and light. The pillars of modern physics , and perhaps the most revolutionary theories in the history of physics, have been relativity theory and quantum mechanics . Newtonian mechanics was subsumed under special relativity and Newton's gravity
1403-633: The Australian mainland and patent the formula. On a train to Sydney, he meets Marie Curie , a Polish-French scientist studying at the University of Sydney, and Preston Preston, the pompous manager of the Sydney Patent Office. Marie is fascinated by Einstein, while Preston is annoyed by him. In Sydney, Einstein lodges in a whorehouse and finds that the patent office will not accept scientific theories. Einstein leaves and meets Marie at

In the latter case, a correspondence principle will be required to recover the previously known result . Sometimes though, advances may proceed along different paths. For example, an essentially correct theory may need some conceptual or factual revisions; atomic theory , first postulated millennia ago (by several thinkers in Greece and India ) and
1586-477: The Hunter Valley, with the second unit at various locations throughout Australia. A 91-minute version of the film was entered in the 1986 AFI Awards where composer William Motzing won Best Music. In 1986, Film Accord sued the production to recover its distribution guarantee and the rushes, claiming the film delivered was not the one it had contracted to buy. The dispute was settled out of court. Serious
1647-530: The Nobel ceremony in Paris that night, attended by many inventors and scientific luminaries. Charles Darwin announces Preston is the winner of this year's Nobel Prize for his beer bubble discovery. Einstein interrupts Preston's speech and questions if Preston knows what happens when an atom is split. When Darwin realizes that Preston has unknowingly built an atomic bomb, he orders Preston to stop. Preston scoffs at
1708-625: The United States. At the APRA Music Awards of 1990 , the soundtrack won Most Performed Australasian Work for Film. Albert Einstein , the son of an apple farmer in Tasmania in the early 1900s, is interested in physics rather than the family business. His father shows him his grandfather's "laboratory", a remote shed where he made beer. His father tells him that they have tried for years to introduce bubbles to beer, saying that
1769-480: The addition of songs by artists such as Paul Kelly , Icehouse and Mental As Anything . This pushed the budget of the film up to $ 5 million. Warner Bros. contributed A$ 4 million to the full version of the film, and would go on to spend $ 8 million on marketing the film in the United States alone. Serious' key collaborators in the movie were co-writer David Roach, co-producer Warwick Rodd and associate producer Lulu Pinkus. He has said it helped that they all shared
1830-419: The applications of relativity to problems in astronomy and cosmology respectively . All of these achievements depended on the theoretical physics as a moving force both to suggest experiments and to consolidate results — often by ingenious application of existing mathematics, or, as in the case of Descartes and Newton (with Leibniz ), by inventing new mathematics. Fourier's studies of heat conduction led to
