Quantum Field Theory Made Easy
|
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.  (April 29, 2014 at 7:48 am)little_monkey Wrote: Just posted another blog, The Essential Quantum Field Theory.

"The greatest deception men suffer is from their own opinions" - Leonardo da Vinci
"I think I use the term “radical” rather loosely, just for emphasis. If you describe yourself as “atheist,” some people will say, “Don’t you mean ‘agnostic’?” I have to reply that I really do mean atheist, I really do not believe that there is a god; in fact, I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one ... etc., etc. It’s easier to say that I am a radical atheist, just to signal that I really mean it, have thought about it a great deal, and that it’s an opinion I hold seriously." - Douglas Adams (and I echo the sentiment)
Primarily, 1st and 2nd year university students in a physics program, and also anyone with a science degree.
QFT is the shit... duh.
 What're your thoughts on the Quantum Eternity Theorem? I'm not sure if that's the actual name of the theorem, but that's what theoretical physicist/cosmologist Sean Carroll called it in his [excellent] debate against William Craig. Which Carroll one by the way, if you're interested in seeing someone clearly beat Craig on both the science and the philosophy.

Just about everything that smells electronics owes its existence to this theory. I read the entire blog post, Joseph, and I have to say, you make it clearer than most. I got through the first three paragraphs before things went fuzzy and my brain started to beat faster. Not your fault - that's what happens when a history major tries to get a handle on physics. Good job, though. I mean as far as I can tell. Boru

Who's your audience?
If it's meant for science undergrads-- looks good. If it's meant for laypeople, I think you need to reduce the numbers down to more basic concepts. Once you pulled out the math, I had no way to know what ideas you were referring to. RE: Quantum Field Theory Made Easy

That I have covered in: The Essential Quantum Mechanics and Harmonic Oscillators, Vacuum Energy, Pauli Exclusion Principle Hope that helps (April 29, 2014 at 6:11 pm)bennyboy Wrote:(April 29, 2014 at 12:24 pm)MindForgedManacle Wrote: QFT is the shit... duh. I haven't watched that video but I have come across WLC's argument on "infinity as potential" and "infinity as actual". Let me make a quick rebuttal: physicists don't care about that. Whenever we do a derivative or an integral, we don't make that distinction between these two. So basically, WLC is rejecting everything that was ever done in science since Newton and Leibnitz invented calculus.
@little_monkey
The video benny posted is a good debate that Craig, in my opinion, looses to physicist Sean Carroll. Trust me, Carroll's stuff in the debate is right up your alley.

When I have the time, I'll take a look at that video.
