Talk:Quantum fluctuation
Ambiguous Terminology[change source]
Some of the words used here could be elaborated upon for an audience not as familiar with discussion in this field. For example, what exactly is a "theoretical" photon, what is an "imaginary" photon, and how are they different in this context? Too someone like me, who doesn't have that much knowledge about this area, it reads like someone's doing a poor job at trying to be funny. I assume this isn't the case.

Perhaps the ambiguous terminology suggests the level of expertise? First matter of business is viewing all four lectures Dr. Feynman gave on the subject of quantum electrodynamics.

For further depth, MIT has some excellent lectures recorded in graduate-level physics. As Dr. Feynman points out, however, you do not need to master such powerful analytic techniques in order to better understand the subject. It has been my experience that the more a professor has mastered a subject, the easier it is to understand his lectures. Dr. Feynman explains things so folks with no background in advanced calculus can grasp the concepts he presents.
I don't know where to start. I have a feeble grasp of the topic, so I can't write an article subject to expert review.
Lets start with Heisenberg's Uncertaincy Principal. If you enter that into https://duckduckgo/, my new favorite search engine, you'll turn up an overwhelming amount of twaddle. All Heisenberg did was to criticise scientists measuring techniques. In order to find an electron, for example, we bounce photons off of it that we can then detect. However, the simple act of bouncing photons off of subatomic particles alters their properties. Until we devise a less intrusive measuring technique, the best we can do is accurately determine the particle's position or its momentum (3d-velocity vectors, sometimes refered to as speed). So we can't say with certainty where a particle is and where it is going, we can chose one or the other, not both. How that is related to quantum fluctuations escapes me.
The other piece of the puzzle is in Dr. Filipenko's presentation of the Casimir Effect. https://www.youtube.com/watch?v=lPzlv6cvs8A
