comment EmDrive Cavity modes
Despite all the controversy this has generated, the problem I think is that people are not look at the obvious, this system does require a power source to operate and therefore generates some "heat". Geometry certainly plays a role in how "heat" is distributed. I don't buy into the advertised theory of the thing, but if it shown it is generating thrust its not because of the physical theory that is claimed. The thing generates "heat" from a power source and is designed to mimic a nozzle. It is not reaction-less as people are concerned, the question is whether it is particularly efficient.

Additional discussion can be found in this paper which discusses how the effects of colliding with the ground serve to shift the direction of spin

comment Ambiguity in number of basis vectors
The issues of incompleteness enter through the axiomization approach developed by Von Neumann, the formalism is absolutely consistent, but the interpretation is left open and depends upon physical observation. Von Neumann was very clear on this point. "Uncertainty" is purely rooted in as part of arbitrariness in the outcome of physical observation. So there is nothing inconsistent in the math, just how we interpret what the math tells us. thefurloff.com/2014/02/12/…
