 Classical physics - Wikipedia, the free encyclopedia
Classical physics is physics based on principles developed before the rise of quantum theory, usually including the special theory of relativity and general theory of relativity.
(In contrast, modern physics commonly refers to the physicist's world view wrought by the revolutionary quantum theory.) There are no restrictions on the application of classical principles, but, practically, the scale of classical physics is the level of isolated atoms and molecules on upwards, including the macroscopic and astronomical realm.
A leading current paradigm of physics is that the fundamental laws of nature are the laws of quantum physics, and that classical theory is the by-product of quantum rules applied to the macroscopic realm.

 Physics - Wikipedia, the free encyclopedia
Physics (from the Greek, φυσικός (physikos), "natural", and φύσις (physis), "nature") is the science of the natural world, which deals with the fundamental constituents of the universe, the forces they exert on one another, and the results of these forces.
Physics is sometimes said to be the "fundamental science", because each of the other weaker sciences (biology, chemistry, geology, etc.) deals with particular types of material systems that obey the laws of physics.
Condensed matter physics, by most estimates the largest single field of physics, is concerned with how the properties of bulk matter, such as the ordinary solids and liquids we encounter in everyday life, arise from the properties and mutual interactions of the constituent atoms.

 Physics
Physics is the science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe.
The body of physics developed up to about the turn of the 20th century, known as classical physics, can largely account for the motions of macroscopic objects that move slowly with respect to the speed of light and for such phenomena as heat, sound, electricity, magnetism, and light.
Classical electromagnetism is summarized by the laws of action of electric and magnetic fields upon electric charges and upon magnets and by four remarkable equations formulated in the latter part of the 19th century by James Clerk Maxwell.

 Why Classical Mechanics Cannot Naturally Accommodate Consciousness but Quantum Mechanics Can
The classical concepts are known to be grossly inadequate at the fundamental level, and this fundamental inadequacy of the classical concepts is not confined to the molecular level: it certainly extends to large (e.g., brain-sized) systems.
There is, therefore, no place within the conceptual framework provided by classical physics for the idea that certain patterns of neuronal activity that cover large parts of the brain, and that have important functional properties, have any special or added quality of beingness that goes beyond their beingness as a simple aggregate of local entities.
But within the deterministic framework of classical physics, where the course of events is the same whether or not consciousness is appended to the local variables specified in classical-physics description, consciousness is non-efficacious, and hence of no relevance to the survival of the species.

 Copenhagen Interpretation of Quantum Mechanics
In experimental cases where the quantization of action plays a significant role, the application of a classical concept does not refer to independent properties of the object; rather the ascription of either kinematic or dynamic properties to the object as it exists independently of a specific experimental interaction is ill-defined.
The quantum mechanical description of the object differs from the classical description of the measuring apparatus, and this requires that the object and the measuring device should be separated in the description, but the line of separation is not the one between macroscopic instruments and microscopic objects.
In emphasizing the necessity of classical concepts for the description of the quantum phenomena, Bohr was influenced by Kant or neo-Kantianism.

 [No title]
Instead, the physical world was asserted to be built out of nothing but quantifiable properties that could be localized in a spacetime, and whose functioning was completely determined by rigid mathematical laws that referred to nothing but these physical properties themselves.
Facilitation, Associative Recall, and Control The persistence of a pattern of neural excitation `etches' this pattern into the physical structure of the brain, in the sense that this pattern is `facilitated' (made easier to activate), and that a later activation of part of the pattern tends to spread to the whole.
In classical mechanics the personally experienced ``I'' is not entailed by the (dynamically complete) physical principles, and it thus lies impotently, and hence without responsibility, outside the causal chain of physical events.

This means that, according to classical physics, there should be no limit to the energy of the light produced by the electrons vibrating at high frequencies.
Classical physicists at the beginning of the century thought they should certainly be able to understand hydrogen, since it is the simplest atom.
This is the trademark of "modern physics." The failure of classical physics to explain flbody radiation, the photoelectric effect, and the hydrogen atom ultimately demolished the foundations of classical physics.

Putting this in a physical context, one could imagine a "demon" who corrupts the supply of qubits but whose actions are unknown to the players (just like a corrupt croupier in a casino).
Continuing in the realm of fundamental physics, we reiterate our belief that a deeper understanding of the relative advantage between classical and quantum many-player dynamical games may eventually shed some much-needed light on the connections between quantum and classical many-particle systems.
Frieden showed that physical laws can be derived by considering the information content of a physical quantity, implying that the process of making a measurement represents a game against nature.

 Why the Difference Between Quantum and Classical Physics is Irrelevant to the Mind/Body Problem
The ground advanced for this claim is that classical mechanics holds that a "physical system is to be conceived of as fundamentally a conglomerate of simple microscopic elements each of which interacts only with its immediate neighbors" (2.12).
In particular, a classical description of a system will include a description of field values at points in the system, but these descriptions record only what is going on at each of the points, and not features of the system as a whole.
That leaves conceptual reduction of mental properties to physical properties at the level of basic theory, but this is equally implausible on either classical or quantum mechanics.
