On the algorithms in phase-shift interferometry

 Rajpal Sirohi

A number of phase-shift algorithms exist in literature. These are categorized as 3-step, 4-step, 5-step etc. with different but constant values of phase steps. In this paper, it is shown that many of them can be deduced from the generalized theory under each category in literature. © Anita Publications. All rights reserved.

What is “Wrong” with Current Theoretical Physicists?

Francis T S Yu
 Emeritus Evan Pugh (University) Professor of Electrical Engineering
 Penn State University, University Park, PA 16802, USA

Theoretical physics uses amazing mathematical paradigm and added with fantastic computer animation provides very convincing results. But mathematical modeling and computer animation are virtual and fictitious, for which many of analytical solutions are not physically real. What is wrong with current theoretical physicists is that they have used mostly a timeless (t = 0) mathematical subspace for their analyses that is not existed within our temporal (t > 0) universe. The reason is: It is not how rigorous and fancies the mathematics (or computer simulation) are; it is the essence of a physical realizable paradigm. For instance; timeless (t = 0) model has been used since the beginning of science; although it has produced uncountable excellent results but, it has also produced many solutions that are timeless (t = 0) or non-existent solutions within our temporal (t > 0) universe. In this article, I will give a few evidences where  the theoretical analyses done by the world renowned theoretical scientists; past and present, have done something wrong to physics. Yet, theoretical physicists were and still are the creators for all the fundamental laws and principles of physics, it is their “responsibility” to take us back to the physically realizable world of science; otherwise we will be still trapped within a virtual timeless (t = 0) land of mathematics. © Anita Publications.

Shades and Reflections of Light

 Rajpal Sirohi

Alabama A&M University, Huntsville, USA

The paper endeavours the history of light and optics from the early Greek period and discusses the contributions made by philosophers and later by scientists in understanding the properties of light. Many of the thoughts expressed by Philosophers and Scientists about the nature of light have been taken from the Internet. © Anita Publications. All rights reserved.
