In this blog, strings of ideas: The Equivalence Principle and the Big Bang Theory,
I explore the idea that Hubble failed to notice an important aspect of Einstein’s Equivalence Principle.
Any comment will be appreciated.
The wikipedia page states the results from a probability density point of view, with no explanation as to how the results were derived. The aim of my blog is to get to the spectrum of fluctuations, which is a quantity that can be actually measured, and is having great interest in particularly...
In my new blog, I kept the spirit of keeping most of the math derivations in the appendices. Heres the preliminary:
Quantum Vacuum Fluctuations - The Basics
Any comments will be appreciated.
For those who are not math inclined, I have placed a good number of the calculations in appendices so that you can concentrate on the main trust which is: in regard to QFTCST, the surprising and unexpected result is that the notion of a vacuum-state and a particle-state, which in flat spacetime...
I understand that this stuff is not easy: few people know calculus, and an even fewer people know calculus with complex number. But that kind of math is absolutely necessary in doing physics at a certain level. The interesting part of EFT is that by a simple Wick's rotation (t →...
Not included in this blog but required is some knowledge of thermodynamics and contour integration. Just to give a perspective on this topic, twenty years ago, EFT was found in some section of a chapter in QFT. Today, in some universities, you will find a full semester course on this subject, a...
Youve probably heard many crazy ideas, and most of the time, they are just that, crazy. But once in a while one of those crazy ideas turns out to be correct. Feynmans idea of the path integral was one of those crazy ideas. In this blog, you will see how Feynman put his "crazy" idea into a...
'll admit the word "easy" might not belong with QFT. But if you would buy your standard QFT textbook - examples: Peskin & Schroeder(842 pages), Srednicki(641 pages), Weinberg 2 volumes (1098 pages), Zee(518 pages), while my blog is about 20 pages when printed out, and you'll get the necessary...
Closed but not quite.
Hilbert's hotel has an infinite number of rooms, all occupied, but one can always find a vacancy for you.
Hilbert space is a vector space extended to an infinite number of dimensions.
Just posted another blog, The Essential Quantum Field Theory. Needless to say, QFT is perhaps the greatest accomplishment of the human mind. Just about everything that smells electronics owes its existence to this theory.
Any comment would be greatly appreciated.
Enjoy.
Just published another blog called The Essential Quantum Mechanics. There's a lot of dry stuff - mathematical definitions, theorems, etc. - but if you are patient enough you will find it gratifying in seeing how the Heisenberg Uncertainty Principle arises from that mathematical formalism, one of...
Just published a new blog on The Essential General Relativity. I wanted to condense a 400 page textbook on the subject in a 1 page blog. I know, that is totally crazy, but I think I managed it.
Comments would be greatly appreciated as I can edit it to make it better.
In the early 1970s there were several applications of QFT to GR, the most famous one was done by Hawking in which he derived that a Black Hole has entropy proportional to its area. A less famous, but equally important, is the Unruh Effect. Whats interesting is that this has certain parallel...
