The Roger Penrose book “road to reality” is getting easier at the end of the books. There is hardly any math in chapters toward the end of the book.
The chapter 18 is full of math concepts. Chapter 20 on Quantum mechanics is full of wave function, its solution, its representation in the special relativity setting. The 4-dimension momentum is also very interesting and tough going.
The dynamic valuable actually is another name for the differential operator on the wave function or the eigenfucntion. They are a form of mental refreshment that I hava not seen for a long time.
This book must be chewed very slowly. Writing down whatever you think is interesting on a note book is also helpful in understanding the topic.
There is very little fact on the General relative model. It is all about quantum mechanics, black hole, big bang, and standard model. Dirac anti particle is also a special topic with a chapterful of narrative.
Juan Cole is hot lately after releasing a new book on Middle East policy. He simply has a different perspective and it is based on the fact finding he did on the ground at Pakistan. The smoke screen put out by the foreign policy crowd in White House is not much different from those of W Bush.
The economics policy and finance policy are almost the same and still under the control of the same group of people previously helping Bill Clinton Administration.
The condition at the work place seems to be getting worse. The pressure cooker is boiling again to put pressure on all the employees.
There are still many bugs in the robot detecting system. The shipping and receiving dept also generates a lot of waste. We do so many extra works for nothing.
