I edited out the first paragraph of my last post, it was too stupidly obvious to even discuss. Regarding what I just quoted, you are in league with Einstein, he said the same thing.

Seriously? That's way cool to know. Thanks.

Re: The strange world of quantum reveled through the double slit experiment

Well, I should be careful because those weren't his same words, but that's clearly what he thought too, he never accepted quantum, he said God doesn't play dice and considered the entangled pair theory (before proved) spooky action at a distance, he just wouldn't accept it.

More on the delayed choice double slit experiment:

Re: The strange world of quantum reveled through the double slit experiment

It would really be something to see the Earth 1000's of years from now or when ever we have evolved into a class 4 civilization, all the people of Earth will be united and our genetics will all be mixed, not that it would matter as we will be able to engineer life and not only choose our children's physical characteristics, but we will be able to alter ours and change them back later just for the experience.

We will need more room than the Earth can provide and will colonize other worlds, many terraformed to meet our needs, others we will alter our physics to live on just to stand the gravity.
Yes once we achieve immortality, we may even seed another class E planet somewhere stable and safe out on the arm of a spiral galaxy just to see how life evolves, as a test, maybe it will be different based on starting parameters and just as proof of concept we may run many test on many planets separated by great time and distance. Wagers will be made as too when the creatures crawl out of the muck, achieve milestones and eventually make the journey to come and meet their creators.

Now as time advances at different rates and we can produce infinite energy from matter we may move further out towards the edges of the universe where all our test life buzzes along like a blur closer in, of course we will be able to warp space time and travel anywhere in moments to collect data from our recorders as information sent in waves are limited to light speed.

Who knows, maybe we are someone's test, and right now Flurb is laughing at Zorg telling him he knew that after the Earthling visited their moon they would get lazy before the next big leap, after all they had barley crawled out of the muck and hardly even understand themselves or the basics of their shortcomings and were bound to revisit already learned lessons before evolving.

Zorg is laughing and saying that batch may never even make it, they are so close to destroying themselves as it is.

My version is published by Princeton Science Library, paperback ~160pgs.

My copy is actually a part of a more inclusive text, Quantum Electrodynamics, Second edition, by Walter Greiner and Joachim Reinhardt. Published 1994. It is formatted to be used as a series of texts in postgraduate physics and has many formulae worked out in full. It's basically 8 chapters beginning with Green's functions as an introduction to nonrelativistic propagator theory. The second chapter is the Stuckelberg- Feynman propagator for electrons and positrons. The third chapter is applications of the relativistic propagator formalism, ranging from simple Coulomb scattering of electrons, Rosenbluth's formula, scattering off extended nuclei, Moller's electron-electron scattering, and Bhabha's electron-positron scattering, along with Compton's scattering. The fourth chapter is a full summary of the Feynman rules. The fifth chapter discusses renormalization with the calculation of the lowest order loop graphs of vacuum polarization, self-energy and the vertex correction leading to the Lamb shift. The sixth chapter introduces the Bethe-Salpeter equation which describes the relativistic two particle system. The seventh chapter addresses the subject of quantum electrodynamics of strong fields, supercritical electron states and the decay of the neutral vacuum. The last chapter is devoted to the theory of perturbative quantum electrodynamics and the treatment of spinless charged bosons. It is 404 pages of mind bending mathematics and can eat up an afternoon in no time at all.

Re: The strange world of quantum reveled through the double slit experiment

I love mathematics, but I don't use it often enough to be good at it. A book like that would take me forever to get through if full of high level math, but interesting to see what the chapters are.

Re: The strange world of quantum reveled through the double slit experiment

Thanks Alaskan. But, I am by no means an expert on this subject. Unfortunately it has been awhile since I've had to use the calculus involved in this book, which is why it takes me so long to get through it.

Don't get too wrapped around the axle by quantum mechanics.
It is a an artificial/man made lattice, a framework---a tool that some find useful.

Quantum mechanics is just another way of looking at what you already know.

Have look at this: Physics and Physicists: Quantum Entanglement For Dummies which begins:
"Over the years, I've given many references and resources on quantum entanglement on this blog (check here for one of the more comprehensive references). Now, obviously, many of these sources are highly sophisticated and not really meant for the general public. It is also true that I continue to get and to see question on quantum entanglement from the public. Worse still, the Deepak Chopras of the world, who clearly do not understand the physics involved, are bastardizing this phenomenon in ridiculous fashion. But the final straw that compelled me to write up this thing is the episode of "Marvel Agent of Shield" from last night where the top brass of HYDRA was trying to explain to Bakshi what "quantum entanglement" is and how Gordon was using it to teleport from one location to another. ABSURD!"
"So while this is all brought about by a TV series, it is more of a reflection on how so many people are really missing the understanding of this phenomenon. So I intend to explain this is very simple language and using highly-simplified picture to explain what quantum entanglement is. Hopefully, it will diminish some of the false ideas and myth of what it is."

While more extreme and humorous--some good points also here: 00SumQM which begins:

"At its core, QM has three of the most ludicrous notions ever devised by man: negative momentum transfer, quasi-particles, and Heisenberg's Uncertainty Principle (UP). Negative momentum transfer is so absurd that we must either conclude that the mathematicians are joking or that they suffer from serious psychiatric disorders. Virtual and quasi-particles are not nouns, but verbs, and this makes you wonder how it is possible for the mathematicians to move what is already in motion. Finally, the sacred ‘principles’ of quantum – Uncertainty and Complementarity – place the observer at the center of inquiry, thus making all inferences subjective. All these far-fetched ideas concocted by the mathematicians are really symptoms of the establishment’s impotence to explain the nature of our Universe"

Re: The strange world of quantum reveled through the double slit experiment

Today, scientists are the modern age priests, they don't like their materials being woo-woo'd one little bit, but I like the woo as well as the hard science, so I'm putting both of them in my pocket, differing regarding the implications or not, I don't care, I'm very pleased with both ways of viewing quantum.

I love Deepak Chopra & his ilk, unfortunately, many in the core of physics dare not speak openly about many of the spiritual implications provided by some of these experiments, but some of the professors will admit they have such ideas too, but they can't mix in their real thoughts on some of these things for fear of being drummed out of their positions by others who would love to do so, as competitive as they are. The ridiculousness of it all is that most have the problem with being unable to speak openly. For myself, I'd rather study what both seeming sides have to say about it than not.
