Phase, as the term is used in audio, usually refers to loudspeaker hookup. In a stereo system, the two loudspeakers should be working in tandem, their cones pushing and pulling at the same time, rather than working against each other. When this condition holds true, the two speakers are said to be acoustically in phase. Conversely, when one speaker pushes forward while the other pulls back, the speakers are out of phase, which usually causes loss of bass and uneven sound. When speakers are out of phase, the situation can easily be corrected by reversing the connections to one of the speakers.

"Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle which has elapsed relative to the origin." Wikipedia, Phase

Newton, who scoffed at Epicurus's idea that "gravitation is essential and inherent in matter," asserted that gravity must be caused by an agent acting, constantly, according to certain laws. Heat, gravity, light, electricity, magnetism, chemical affinities, are all different phases of the primal force discovered by Keely, and all these forces, it is said, can be obtained from a single ray of sunlight. "The evidence of unity or oneness even between the physical, vital, mental, and spiritual is seen in the light of this law of correlation," says J. J. Smith. "A great portion of our muscles contract and relax in obedience to our wills, thereby proving that the mental force can be, and is, in every such instance actually converted into the muscular or the physical." Keely demonstrates the truth of this assertion, claiming that "all forces are indestructible, immaterial, and homogeneous entities, having their origin and unity in one great intelligent personal will force."

the alteration of the above fermentation process at its most fundamental phase. To make this even clearer: Allotropic oxygen conformations are liberated through pressure- and heat-intensifying dynamic effects or volume-enlarging thermal influences, because the fat-concentrates with opposite polarity become inactive and are maintained in a passive state under such influences. This results in the inner fission (dissociation) of the previously internally interconnected and highly evolved, therefore extremely pressure- and heat-sensitive trace-elements, which like yeasts initiate the process of raw-material transformation - the fermentation process described above.
