A trek through Physics

What is this?

This is a walkabout through the land of physics. It is an adventurous trek. In going back through the various concepts, I find that all I learned about physics is still there in my mind; but when I dredge it up out of my memory, the concepts have been reduced to a simpler form than when I learned them. They are also much better connected. It is that connectivity which has guided my choice of topics and how I treat them.

In the past, I have struggled with the idea of writing a book on physics that anyone could understand. I have taught a variety of courses in physics; but I found that any book that tries to present the subject of physics in  a serious manner cannot ignore the math. One can write an entertaining series that does not connect with how physics can be done, so that the student is left with the impressions that can be used in only vague ways.

In this particular trek, I will cover various aspects of physics in the way that they come out of my mind. In this form they make sense to me; but later, if I get proper feedback on the physics, I will try to adapt what I have written into a form that is understandable to as wide an audiance as possible.
