Since its inception it has broadened to find applications in many other areas, including statistical inference, natural language processing, cryptography, neurobiology, the evolution and function of molecular codes, model selection in ecology, thermal physics, quantum computing, plagiarism detection and other forms of data analysis.

Since energy is dependent on reference frame ( upon the observer ) it is convenient to formulate the equations of physics in a way such that mass values are invariant ( do not change ) between observers, and so the equations are independent of the observer.

Since the current laws of physics are only known to be valid in this universe, it is possible that the laws of physics are different in parallel universes, giving a God-like entity, more power.

Since it is assumed in cosmology that the particles we see were created using the same physics we measure today, it would normally be expected that the overall baryon number should be zero, as matter and antimatter should have been created in equal amounts.

Since the 20th century, the work of physics research has been divided between theorists and experimentalists ( see scientific method ).

Since the chain conformations of a polymer sample are quasi infinite in number and constantly change over time, the " radius of gyration " discussed in polymer physics must usually be understood as a mean over all polymer molecules of the sample and over time.

Since the beginning of the 20th century, quantum mechanics — the physics of the extremely small — has revealed previously concealed aspects of events.

Since Millikan's work formed some of the basis for modern particle physics, it is ironic that he was rather conservative in his opinions about 20th century developments in physics, as in the case of the photon theory.

Since a vector field is quite difficult to visualize at first, in elementary physics one may instead visualize this field with field lines.

Since Bloch's theorem applies only to periodic potentials, and since unceasing random movements of atoms in a crystal disrupt periodicity, this use of Bloch's theorem is only an approximation, but it has proven to be a tremendously valuable approximation, without which most solid-state physics analysis would be intractable.

Since then, metallic hydrogen has been described as " the holy grail of high-pressure physics ".

Since field theory problems are more common in modern physics than mechanics problems, this field theory version is the most commonly used version of Noether's theorem.

Since the laws of physics at such short distances are unknown, some find Hawking's original calculation unconvincing.

Since most varieties of particle occur only as a result of cosmic rays, or in particle accelerators, particle physics is also called high-energy physics.

Since the peculiar, non-linear physics of the ear doesn't come into play in this case, it is thought that this must be a separate, neural phenomenon.

Since processing cycles are always at a premium, physics programmers may employ " shortcuts " that are computationally inexpensive, but look and act " good enough " for the game in question.

Since 1964, there is a discussion about the violation of the principles of quantum physics in explanation of the Josephson effect in the framework of the BCS theory.

Since 1914, Molien was a professor at higher Siberian courses for women in Tomsk, and when in 1917 the faculty of physics and mathematics was opened at the Tomsk State University, he got a professorship there, and stayed at that university until his death on December 25, 1941.

Since we require the process to be adiabatic, the following equation needs to be true

Since one person needs to cover the entire court, singles tactics are based on forcing the opponent to move as much as possible ; this means that singles strokes are normally directed to the corners of the court.

Since the 1989 coup and subsequent expulsion of South African-financed mercenaries, Comoros likewise turned away from South Africa and toward France for assistance with its security needs.

* Since the insulin pump needs to be worn most of the time, pump users need strategies to participate in activities that may damage the pump, such as rough sports and activities in the water.

Since most metals are present in ores as oxides or sulfides, the metal needs to be reduced to its metallic form.

Since 1999, the government has embarked on reforms in higher education designed to meet the needs of a growing population.

Since the incubation period of prion diseases is so long, an effective drug does not need to eliminate all prions, but simply needs to slow down the rate of exponential growth.

Since its launch, the program has continued to grow and refine its procedures to better accommodate a growing campus ' needs.

Since the late 1950s, aerospace engineers have used the term " unobtainium " when referring to unusual or costly materials, or when theoretically considering a material perfect for their needs in all respects, except that it does not exist.

Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts.

Since the efficiency of a rocket engine is related to the square root of the temperature of the working fluid, the solid core design needs to be constructed of materials that remain strong at as high a temperature as possible.

Since one cannot completely ignore the bit error-rate of the medium, each switching node needs to implement error detection to avoid wasting bandwidth due to the transmission of erred frames.

Since each T1 frame contains 1 byte of voice data for each of the 24 channels, that system needs then 8, 000 frames per second to maintain those 24 simultaneous voice channels.

Since temperature in principle also depends on altitude, one needs a second equation to determine the pressure as a function of height, as discussed in the next section.

Since every area is different, the government takes that into consideration and will provide different areas with different institutions to fit their needs thus there will be different changes in social capital in different areas.

Since it requires less energy to place a satellite into a LEO and the LEO satellite needs less powerful amplifiers for successful transmission, LEO is still used for many communication applications.

Since the beginning, the company has also been a manufacturer of microscopes and optics for specialised needs, such as medical use.

Since all the braking operations exert pressure on the back plate, it needs to be very strong and wear-resistant.

Since then the private detective industry has grown with the changing needs of the public.

Since it was quite easy to stack interconnections ( wires ) inside the embedding matrix, the approach allowed designers to forget completely about the routing of wires ( usually a time-consuming operation of PCB design ): Anywhere the designer needs a connection, the machine will draw a wire in straight line from one location / pin to another.

Since the islets had an " undefined internal status ", the immigrants did not benefit from the Spanish immigration laws and, under a joint operation, Spanish troops tended to the women, children, and medical needs of the immigrants, then turned them back over to Morocco.

Since the early 1980s, however, desalination plants, which render seawater suitable for domestic and industrial use, have provided about 60 % of daily water consumption needs.

Since each person experiences a disability differently and therefore has different needs for assistance, each dog is to some extent custom-trained for the individual it will be helping.

Since its commencement over 20 years ago, LETSystems have been highly innovative in adapting to the needs of their local communities in all kinds of ways.
