In most, if not all, introductions to classical mechanics, the mass is assumed to be constant. Usually this is mentioned and often attention is drawn to such systems as rocket motion to indicate that, in practice, the mass is not always a constant. In truth, many students actually meet a varying mass for the first time when introduced to the Special Theory… (More)

In a recent article 1 , Enders raised queries concerning the existence of physical systems which obey Maxwell-Boltzmann statistics. Here the question is considered from a different angle and answers are proposed which support the existence of such statistics within the framework of physics.

The Lagrange equations of motion are familiar to anyone who has worked in physics. However, their range of validity is rarely, if ever, a topic for discussion. Following on an earlier examination of the consequences for these equations if the mass is not assumed constant, this note will look carefully at the other assumptions made and consider any further… (More)

Black holes, thermodynamics and entropy are three topics which both separately and together raise several quite deep and serious questions which need to be addressed. Here an attempt is made to highlight some of these issues and to indicate a possible linkage between the accepted entropy expression for a black hole and the paradox linked to black holes and… (More)

Here an introduction to Wesley's neomechanics is presented. It is shown to produce some of the same results as Special Relativity but without both the mathematical and philosophical basis of that subject. As with other work in which results associated with General Relativity are obtained without recourse to the fundamental bases of that subject, so here too… (More)

There is neither motivation nor need to introduce 'superstatistics.' The authors attempt to generalize the Boltzmann factor so as to obtain a more general statistics, i.e., their so-called superstatistics. The do so by performing a Laplace transform on the probability density function (pdf) of an intensive variable, f (β), where β is the inverse… (More)

The derivation of Student's pdf from superstatistics is a mere coincidence due to the choice of the χ 2 distribution for the inverse temperature which is actually the Maxwell distribution for the speed. The difference between the estimator and the variance introduces a fluctuating temperature that is generally different than the temperature of the variance.… (More)
