In the section Cosmic application what does this sentence refer to:
The consequence of this is that charged particles moving in very highly magnetised space
plasmas, are somewhat different to what is seen in the laboratory
I think this refers to magnetic fields in space being significantly greater than that which can be reproduced in the laboratory. -- Iantresman 10:59, 21 December 2005 (UTC)
In the section Dimensionless parameters in tokamaks what are these parameters:
The remaining (dimensional) parameters can be taken to be n, T, B, and R.
I find the subject of this article highly interesting, but it is badly written; I hope someone would improve it to the point of a stand-alone encyclopedia article. -- DelftUser 19:34, 14 December 2005 (UTC)
In base dimensions the parameters are:
Particle density n: has dimension 1/length3
The temperature T: has dimension thermodynamic_temperature
The magnetic field B: has dimension mass/(electric_current*time2)
There is no way that β has dimension 1. -- DelftUser 19:07, 20 December 2005 (UTC)
I'm afraid I wrote most of that section, but it has been some time and I couldn't say anymore where my info came from. I think most of it can probably be found in Application of dimensionless parameter scaling techniques to the design and interpretation of magnetic fusion experiments, but that is not light reading.

In the section "A commonly used similarity transformation", it would help to have a motivating sentence before the long chain of deductions starts.
For example, can the reader assume that the basic rescaling is a rescaling of length, given by the ratio x, then view the others as flowing from that? 89.217.22.3 ( talk) 09:21, 8 November 2014 (UTC)
The objection in this section seems to be so strong that it makes it look not like a scaling, but a mistake.
A scaling transformation should take solutions to solutions. Is this really possible if the ionization ratio changes? Or are all plasma scaling transformations only approximate?
(But only in the sense that the linear function x is approximately constant...) 89.217.22.3 ( talk) 09:27, 8 November 2014 (UTC)
This whole article is based solely on one reference, which is both theoretical and is unsupported by cosmologists or astrophysicists, and is the mantra of Plasma cosmology. It should be either removed as a deleted article or greatly cut in size. Arianewiki1 ( talk) 07:55, 2 February 2017 (UTC)
Why is this plasma scaling not part of plasma (physics) ? It should be clearer in the intro. Needs a hatnote, or convert to a disambiguation ? It looks like a non standard use of the term "plasma scaling" - as in scaling laws in tokamak design. - Rod57 ( talk) 12:19, 28 June 2022 (UTC)
