In 1842, Austrian physicist Christian Doppler discovered that frequency of wavelengths tends to change with the movement of wave source in relation to an observer. If that sounds too complex, in convenient terms you can ask what is the Doppler Effect simple explanation? Doppler Effect is the incr...
In the context of the relativistic Doppler effect [DE] and the Lorentz-Fitzgerald contraction [LF], we investigate the consequences of two abstract axioms [R] and [M] expressed in terms of an operation generalizing the addition of velocities and a function. The latter can represent either the...
Huygens' Principle (1678) implies that every point on a wave front serves as a source of secondary wavelets, and the new wave front is the tangential surface to all the secondary wavelets. But two problems arise: portions of wavelets that exist outside o

On the basis of Galilean invariance and the Doppler formula, combined with an observational condition, it is shown that the constancy of the velocity of lightin vacuocan be derived, together with time‐dilatation and Lorentz contraction. It is not necessary to take the constancy as a postulate....
Motion of the endocardial surface in diastole is the resultant effect of wall thinning. Endocardial wall motion to transmitral flow (Doppler E-wave) relations that predict wall thinning are derived using conservation of myocardial volume, two simplified (spatiotemporally homogeneous) left ventricular...
