  Classical mechanics - Wikipedia, the free encyclopedia
In physics, classical mechanics is one of the two major sub-fields of study in the science of mechanics, which is concerned with the motions of bodies, and the forces that cause them.
The initial stage in the development of classical mechanics is often referred to as Newtonian mechanics, and is characterized by the mathematical methods invented by Newton himself, in parallel with Leibniz, and others.
Although classical mechanics is largely compatible with other "classical physics" theories such as classical electrodynamics and thermodynamics, some difficulties were discovered in the late 19th century that could only be resolved by more modern physics.

 A critique of Newtonian physics by Alex Paterson
Newtonian Physics theory is based on the late 17th century notion that the Universe is made up of solid objects which are attracted towards each other by a force called 'Gravity'.
Newton's Laws of Motion (Newtonian Mechanics) successfully described the motions of planets, mechanical machines and fluids and this success gave rise to the notion that the laws of Newtonian Physics were basic laws of nature and as such were immutable.
Newtonian physics (although interestingly enough, not Newton himself) maintained that everything in existence could be described "objectively" because all phenomena were strictly a result of the physical interactions of all its physical parts.

 Classical mechanics   (Site not responding. Last check: 2007-10-21)
Classical mechanics is a model of the physics of forces acting upon bodies.
It is often referred to as "Newtonian mechanics" after Newton and his laws of motion.
In particular, classical nonrelativistic electrodynamics predicts that the speed of light is a constant relative to an aether medium, a prediction that is difficult to reconcile with classical mechanics and which led to the development of special relativity.

It was, in fact, a reaction to the basic assumptions of another revolution in physics and astronomy which marked the emergence of modern science in the seventeenth century.
Then, after meticulously defining the physical terms necessary for his considerations, he used a revolutionary mathematical method to calculate the movements of the moon and the planets and showed his results to match those obtained by observational astronomy.
Its impact on science was trifold: it gave the three laws of motion and the law of gravity to physics, and differential calculus to mathematics.

 Newtonian and Relativistic Conservation Laws
Indeed the Newtonian force of gravity was considered to be an agent of such "action at a distance", whereby separate bodies could exert mutual influence on each other, and mutually change their states of motion without being in direct contact with each other.
This shows that in relativistic physics the transference of mass-energy is subject to formally identical conditions as are imposed on the transference of mass in Newtonian physics.
Of course, as in the case of Newtonian mass, we could imagine the possibility of higher-order interactions (e.g., trinary interactions), in which transference at a distance would not be immediately ruled out on the basis of the conservation laws with respect to any single inertial reference frame.

 Newtonian mechanics - Wikipedia, the free encyclopedia
The original version of the physical discipline of mechanics, due to Sir Isaac Newton, who developed the theory over a period from about 1664, until the publication of his great work, known as the Principia, in 1687.
While Newton chose to present the work in classical geometric form, for acceptance, much of the foregoing development of the theory was actually based on his invention of the calculus of infinitesimals, as a new discipline of mathematics.
It was eventually in this form, which laid the foundation of so much of todays science and mathematics, along with the differential calculus of G.W. von Leibniz, that Newtonian mechanics evolved into the theory of classical mechanics.

 A Response to Common Questions Concerning the Article: "Postmodern Deconstruction Of Newtonian Science: A ...
Newtonian mechanics, although this fact is downplayed in the university’s training of scientists (or perhaps sometimes outright denied), is composed of two components—one mathematical-empirical and the other metaphysical.
Relativity theory has overturned the metaphysics of Newtonian mechanics where the velocities of objects approach the speed of light or the acceleration forces of gravity become extreme; but Newtonian metaphysics remains firmly in place in the classical world of large objects where these conditions are not met.
Indeed, relativity and quantum theories, which in their respective domains overturn the conventional metaphysics of Newtonian mechanics, may be just the beginning of a general theory of causality in science that overturns as well the metaphysics of Newtonian mechanics in classical physics.

It is called Process Physics because it uses a process model of time rather than, as in current physics, a non-process geometrical model of time, a model so successfully developed and used by Galileo, Newton, Einstein and others that for many physicists the phenomenon of time is actually identified with this geometrical model.
Their published data revealed to them the expected fringe shifts, but that data gave a speed of some 8km/s using a Newtonian theory for the calibration of the interferometer, and so was rejected by them solely because it was less than the 30km/s orbital speed of the earth.
Abstract: It is shown that both the Newtonian and General Relativity theories for gravity may be re-formulated as in-flow dynamics in which a substratum is effectively absorbed by matter, with the gravitational force determined by inhomogeneities of that flow.

 Physics > Special relativity
The special theory of relativity (SR) is the physical theory published in 1905 by Albert Einstein that modified Newtonian physics to incorporate electromagnetism as represented by Maxwell's equations.
The theory is called "special" because the theory applies only to the special case of measurements made when both the observer and that which is being observed are not affected by gravity.
Special relativity is now universally accepted by the physics community, unlike General Relativity which is still insufficiently confirmed by experiment to exclude certain alternative theories of gravitation.
