"The Lorentz Transformation for Velocity"
    It is recognized that Special Relativity provides the Lorentz
Transformations for Length and Time and Mass between reference frames having
a relative velocity. What is too often not recognized that, in so doing, it

"Are Unified Field Theories Justified?"
    Modern physics seems to be searching for ways to incorporate all
physical phenomena into a single unified theory. The question that comes to
mind is why? The question arises as to the conceptual need for such an

When light passes through glass, is it described as:
1) The quantum field is modified because of the glass and a single
interaction occurs - light source EM particle to final other EM particle.
Sum of all paths but with the glass eliminating some of the more direct

Is it possible that photons are simply spinning combinations of one
electron and one positron?

"How Does Light 'Know' How Fast to Travel?"
    One of the basic beliefs of modern physics is that the velocity of
light is the same wherever and whenever it is measured. It is, in the
language of physics, invariant. To illustrate this understanding, let us
