The Laws of Physics :

The Significance of Physics

Physics is the underlying "parent" of the other sciences. Those sciences; for example: chemistry, optics, thermodynamics, mechanics, biology, electricity, and so forth; developed out of detailed observation of natural behavior. The development of a particular science progressed from detailed data collection through analysis and hypotheses to a body of descriptions of behavior abstracted from that data. We call those descriptions "physical laws". They are empirical laws, that is conclusions based on observed behavior.       

While the original development of the sciences was from their specifics toward the general, now that the body of developed specifics and resulting physical laws exists, it is more logical to comprehend that body of knowledge in terms of its hierarchical structure by starting at the common central data, the presentation being from the general to specifics.

All of physics [and, therefore all of science] is fundamentally reducible to:

· Particles, the basic material or matter of the universe,
· Forces, which act on or interact between or among particles, and
· Motions of the particles as a consequence of the forces.

Various manifestations, combinations and interactions among these produce all of the world and universe that we experience:
· substances and objects,     · Light, heat, energy;     · the world, the universe.

· PARTICLES
The fundamental physical characteristics of particles are their:
· mass                              · electric charge                  · state of motion
A small number of fundamental physical laws describes the forces that act on particles and their consequent behavior [motions].

The Fundamental Physical Laws are:

· FORCES
    - Coulomb's Law - the force between electric charges [electrostatics]
    - Ampere's Law - the force between electric currents - charges in motion [electromagnetics]
    - Newton's Law of Gravitation - the force between masses

· MOTIONS
    - Newton's Laws of Motion:
       1 - A particle moves in a straight line at constant velocity when not acted on by any forces.
       2 - A force acting on a particle imparts an acceleration to the particle, the direction being that of the force and the magnitude proportional to the particle's mass
       3 - Whenever a force acts on a particle [which force is always due to interaction with another particle] a force of equal magnitude and opposite direction acts on the other particle.

All of these Fundamental Physical Laws, and the further developments from them in the various sciences inclusive within physics, are derived and proven in The Origin and Its Meaning from the characteristics of that origin, derived and proven in the same sense and with the same rigour as proofs in Euclidean Geometry [although deriving and proving the Laws of Physics is much more complex than geometry], as outlined in the following extract from the Table of Contents.

Thus, we can know that the origin of the universe presented in

The Origin and Its Meaning

is correct because

while that origin is metaphysical, that is, not itself within physics,

it nevertheless leads directly and precisely to the known physics of today's universe,

which an invalid origin could not do.
