Yes, I read some of that out of the mainstream. Some articles of that kind have been written by scientifically prepared people, even by university professors. All agree in denouncing the interested suppression of an essential part of the first publication made by Maxwell. They also reject the compact form Heavside gave to the theory, replacing the original 20 quaternion equations with 4 vector equations. I've only read out of curiosity. I have not delved into the subject. You do?

I have not delved into the subject. You do? Me neither. I am not a mathematician. As the magnetic field is a rotating body in itself, it is absolutely reasonable to apply the quaternion algebra to it. The reason why I believe it is the key: I have gathered certain evidence that proves the incompleteness of our current EM field theory. If you are using vector algebra, that is sub-par to quaternions, you are missing some parameters of the field in question. Edited August 25, 2018 by neuerwind

This is, as you say, correctly handled by using quaternions. Mathematically quaternions were superceeded by tensors. 1
neuerwind2 Posted August 26, 2018 Posted August 26, 2018 34 minutes ago, Markus Hanke said: The modern formalism of the Maxwell equations uses differential forms. This formalism is fully covariant, and all of classical electrodynamics reduces to two very simple statements: dF=0 d⋆F=4π⋆J These statements are more than simple: they are primitive. As I said, the magnetic field is a rotating body. Instead of having Rot and Div operators in two-dimensional space, science could employ a fully three-dimensional representation.

What I wrote there isn’t primitive - it’s the full covariant Maxwell equations in 4-dimensional spacetime. It encompasses all of classical electrodynamics. Also, the curl and divergence operators are defined in 3-dimensional (Euclidean) space, they are not 2-dimensional. 2

Vector algebra stipulates that we analyze rotary motion by projecting it on flat surfaces. On the contranry, the quaternion is a perfect mathematical representation of a rotating body per se.

For example: https://www.researchgate.net/publication/275832913_Polar_and_axial_vectors_versus_quaternions Thank you for that link, I had not seen it and it is a well balanced article. +1 However the two types of calculus you are referring to are not diferences between quaternions and vectors (Professor Weatherburn's texts had a good discussion of both if I remember rightly, I will have to look them up again) Marcus referred to the star operator. The differences are due to what are known as Clifford algebras and the Exterior v the Interior calculus. This is equivalent to the use of Dual spaces in vector algebra (=linear algebra as vector spaces) In such spaces, tensors (which I mentioned before and you didn't respond to) are vectors. An even more mixed up mahtmatical notation. Edited August 27, 2018 by studiot

Unfortunately, I'm lacking proper mathematical background to discuss all pros and cons of tensors vs. quaternions. My point: if you'd like to obtain new results, you should use the new maths. And quaternions are not exactly 'new' to this field, as Maxwell tried to employ them, too. 2 minutes ago, beecee said: You DON'T make non mainstream claims in the mainstream sections...PERIOD, particularly hypothetical unsupported nonsense which you have appeared to have done so far.

Here is an extract from Artzy : Geometry an Algebraic Approach, if you want more to see how quaternions have been brought into the fold of modern algebra. Note the next one up is the octave algebra.
