Casimir Effect
I am going to change the wording wrt the Casimir effect. I'm not an expert in this area, but I have seen several research articles refuting claims that the effect can only be explained by the QCD vacuum rather than the much more pedestrian di-, quadru-, etc.-polar electrical fields of the two near-by plates. I am going to change it to "widely used, but controversial, examples" from "best known examples". Please, before you "knee jerk" a response to this sacriligious violation of the "received wisdom" (aka status quo), research it. Thanks.72.172.11.140 (talk) 00:48, 3 February 2014 (UTC)

Casimer Effect free energy is pseudoscience
In order for a force (such as that asserted by the Casimir effect) to perform useful work W, it must act through a distance d, which in the case of a pair of Casimir plates, is for all intents and purposes, zero.

Perhaps the wormhole interpretation of the Casimir effect is an attempt to circumvent such analysis. It probably does not rate inclusion or mention in an article about the vacuum expectation value, which is actual science. Danshawen (talk) 00:48, 19 March 2014 (UTC)danshawen

Calculation
This article would really benefit from showing the calcuation of a VEV. — Preceding unsigned comment added by 70.247.173.205 (talk) 01:53, 6 February 2016 (UTC)


 * there is the formula $$M_W = \tfrac{1}{2}vg$$ which I guess must be in SI: $$M_W = \tfrac{1}{2}vg \frac{1}{c^2q_P \pi \sqrt {\alpha_W}}$$ using $$\alpha_W=1/128$$??? Ra-raisch (talk) 07:50, 7 August 2017 (UTC)
 * there is another formula: $$v = 1/\sqrt{\sqrt 2 G_F^0}$$ using $$G_F^0=G_F/(\hbar c)^3$$ Ra-raisch (talk) 08:38, 7 August 2017 (UTC)
