Some grand unified theories of particle physics also predict that a single proton can decay, changing the baryon number by one ; however, this has not yet been observed under experiment.

Some of these constructs, such as space and time, correspond to the way the world is structured by the laws of physics ; for others the correspondence is not as clear.

Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light.

Remark: Some authors, especially in physics and matrix algebra, prefer to define the inner product and the sesquilinear form with linearity in the second argument rather than the first.

Some fields, such as the theory of dynamical systems, or game theory, are classified as applied mathematics due to the relationships they possess with physics, economics and the other sciences.

Some modern day physicists and science writers such as Paul Davies and John Gribbin have argued that scientific finds in physics such as quantum mechanics and chaos theory have disproven materialism.

Some experiments show evidence of tetraquarks —" exotic " mesons made of two quarks and two antiquarks ; the particle physics community regards their existence as unlikely, although possible.

Some recent work has been done in analysis using concepts from non-standard analysis, particularly in investigating limiting processes of statistics and mathematical physics.

Some physicists take up additional careers where their knowledge of physics can be combined with further training in other disciplines, such as patent law in industry or private practice.

Some examples of epistemic probability are to assign a probability to the proposition that a proposed law of physics is true, and to determine how probable it is that a suspect committed a crime, based on the evidence presented.

Some basic parts of physics are:

Some particle physics experiments must adjust for terrestrial tides.

Some key developments in biology were the discovery of genetics ; Darwin's theory of evolution through natural selection ; the germ theory of disease and the application of the techniques of chemistry and physics at the level of the cell or organic molecule.

Some words, including " mathematics " and " physics ", have developed true mass-noun senses despite having grown from count-noun roots.

Some forms of determinism can be tested empirically with ideas stemming from physics and the philosophy of physics.

Some parts of this model have been updated by recent findings in mineral physics ( see post-perovskite ) and supplemented by seismic tomography.

Some scientific experts have however called Kalam a man with no authority over nuclear physics but who just carried on the works of Homi J. Bhabha and Vikram Sarabhai.

Some of the things investigated by surface physics include surface states, surface diffusion, surface reconstruction, surface phonons and plasmons, epitaxy and surface enhanced Raman scattering, the emission and tunneling of electrons, spintronics, and the self-assembly of nanostructures on surface.

Some practitioners assign different effects based on the orientation of the magnet ; under the laws of physics, magnetic poles are symmetric.

Some philosophers also appeal to a specific theory which is " timeless " in a more radical sense than the rest of physics, the theory of quantum gravity.

Some schools were a type of specialized school with a specific focus in a particular field or fields such as mathematics, physics, language, science, sports, etc.

Given an isolated physical system, the allowed states of this system ( i. e. the states the system could occupy without violating the laws of physics ) are part of a Hilbert space H. Some properties of such a space are

Some examples of naive physics include commonly-understood, intuitive, or everyday-observed rules of nature:

Eddington went so far as to claim that a sufficiently wise mind could deduce all of physics, illustrating his point with the following joke: " Some men went fishing in the sea with a net, and upon examining what they caught they concluded that there was a minimum size to the fish in the sea.

Some of GLUT's original design decisions made it hard for programmers to perform desired tasks.

Some Unix programmers argue that traditional command-line POSIX tools constitute a complete development environment, an IDE, though one with a different style of interface and under the Unix environment.

Some programmers still use makefiles and their derivatives.

Some studies have found that programmers working in pairs produce shorter programs, with better designs and fewer bugs, than programmers working alone.

Some real-time software 3D engines based on ray tracing have been developed by hobbyist demo programmers since the late 1990s.

Some programmers feel that these syntax usability features are either unimportant or outright frivolous.

Some programmers, including Dan Bernstein, getmail creator Charles Cazabon and FreeBSD developer Terry Lambert, have criticized Fetchmail's design, its number of security holes, and that it was prematurely put into " maintenance mode ".

Some programmers consider the " p-code " generated by some Pascal compilers, as well as the bytecodes used by. NET, Java, BASIC and some C compilers to be token-threading.

Some compilers in this category provide special constructs or extensions to allow programmers to directly specify operations to be performed in parallel ( e. g., DO FOR ALL statements in the version of FORTRAN used on the ILLIAC IV, which was a SIMD multiprocessing supercomputer ).

Some manufacturers avoid this problem by explicitly and completely defining the execution order of a rung, however programmers may still have problems fully grasping the resulting complex semantics.

Some programmers who had worked on the original ICS became unhappy with what they saw as the commoditization of their project.

Some authors – see, for example, Creating a Software Engineering Culture by Karl E. Wiegers – have stressed the importance of the social and political aspects of the work climate as determinants of the effectiveness of individual programmers and the project team as a whole.

Some languages ( e. g. C ++) leave this to programmers.

Some programmers such as Jamie Zawinski feel that spaces instead of tabs increase cross-platform functionality.

Some programmers may specialize in one area of game programming, but many are familiar with several aspects.

Some of those programmers attended the OOPSLA and PLoP conferences about object-oriented programming, posting their ideas on the PPR and exchanging e-mail messages with Ward.

Some early programmers combined instructions and data in words as a way to save memory, when it was expensive: The Manchester Mark 1 had space in its 40-bit words to store little bits of data – its processor ignored a small section in the middle of a word – and that was often exploited as extra data storage.

Some programmers nicknamed the finished product LOL memory, for Little Old Lady memory.

Some device programmers serve a double purpose for programming as well as debugging the device.

Some assembly language programmers reject HLA out of hand because it allows programmers to do this.

Some systems will e-mail interested parties, such as the submitter and assigned programmers, when new records are added or the status changes.

Some uncreative programmers would create game quests in which the goal was to guess the proper syntax to an uncommon command.
