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.
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...
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...
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...
Or, Scientists work to produce 'Star Trek' deflector device. A trip to Mars can't be that far away.

Ok, time for some edumecation.
Last time, we explored how Einstein derived his famous equation, E = mc^2
See: strings of ideas: Einstein's Derivation of the Famous Equation, E=mc2
One of those equations was taken for granted.
γB+ = ½ E(1 + (V/c)cosΦ V^2/c^2)^-½
At the time that...
Launch is scheduled for 2018, time enough for those who want to volunteer. Any takers?

Quite surprisingly, you just need ordinary algebra, no calculus, no tensors to scare the hell out of you.
Enjoy.

Suppose we want to probe the Planck scale. However, QM + GR gives us black holes, and so it is impossible to know from any experiment what's going on at Planck scale.
See how this derived from fundamental principles here:

Often you get on a forum and some people are claiming that Einstein proved Newton wrong. Well, not exactly. Einstein Field Equations reduces to Newton's law of gravity at low gravity and low velocity. I've made the calculations available. So any time you get to meet those people, you can refer...
So the questions are:
1. Once in Heaven, can you sin? If not, you have no free will.
2. If yes, can you be banned from Heaven for having sin? If yes, then salvation is not eternal and chances are, one by one, over an eternity, we will all be banned.
3. If no, then God is in for a very rough...
