Re: "Unified Revolution" new book by Espen Haug

Collector, just an esthetic question for the viXra paper.

After each equation, it looks like you are starting a new paragraph while it "should" be a new line with no indentation.

for example, after equation (1), it "should" be:
and when v .....
and when v ....

But may be it is the viXra latex template formating.

It's not latex, it's xetal (Possibly there's an unnecessary empty line after the equation in the latex code.)

"Possibly there's an unnecessary empty line after the equation"  dont u know my theory contains also the void? is there really a better way to describe the void than void-space?   ohh yes that is one way to fix it. or \noindent   thanX

Re: "Unified Revolution" new book by Espen Haug

Thanks TW, ohh yes I now start to understand a little, I am novice on wave functions and operators. Yes I see the regular wave function is a scalar

so possibly I could switch to div operator as then get scalar ?

-  \frac{\partial \Psi}{\partial t}=- \nabla\cdot(\Psi \textbf{c})

I am not sure this gives meaning, is consistent, or even if my notation is right...I need to study more here, any good book on "vector and scalar operators for novices in 24 hours" ?

(PS my erroneous wave equation do not alter my analysis on de Broglie versus Compton etc and the momentum etc, but yes my wave equation not properly derived)..

Also I am still wondering about the imaginary numbers in the standard wave function $e^{i....}$ (that I borrowed from standard QM), is it somehow also linked to the Old Mystical formula?

"Thus the essence of this postulate can be expressed mathematically very concisely in the mystical formula: $3\times 10^5 \mbox{ km} =\sqrt{-1}$ seconds" Henry Minkowski  (we are living in the mystical esoteric age of physics

tw:
It was only a trivial observation but for you is psi a scalar function? (as in a regular wavefunction).
partial psi/partial t is then a scalar,  but grad(psi) is a vector?

When  I was a yoof I used Eisberg and Resnik I wished I hadn't sold it to go on holiday looking at the Hardcover price today.

Re: "Unified Revolution" new book by Espen Haug

I used Schaum's Vector Analysis by Murray Spiegel in term 1 in year 1 of undergrad during rites of passage.

@Collector
Here is my ONE HOUR slide show from my preamble part of my online course  that exactly addresses the questions you had (zip file). Specially for you.

Crucial is scalar field vs vector field (aka scalar-valued and vector-valued functions for pure maths folk).

How do you know you are talking to an engineer? they call $\mathbb{\nabla}$ "nabla"

I think the French call Curl "rot"?? The Germans certainly do.

Re: "Unified Revolution" new book by Espen Haug

I found also this undergrad course for engineers:  https://www.robots.ox.ac.uk/~dwm/Courses/2VA_2015/

Daniel, better to convert your pptx to a "universal" format (like a pdf). I am unable to open it correctly with LibreOffice on Linux (the formulas are not rendered well):

Re: "Unified Revolution" new book by Espen Haug

Thanks, Farid.
This is an issue in general. what we do is export ppt -> word -> pdf. I'll get back.
Do you have MS Office?

More correct is to say in french (not the French), the Curl is "rot" for "rotationnel". The rotational is also noted as $\mathbb{\nabla} \wedge V$, $\mathbb{\nabla} \times V$, $\vec{\mathbb{\nabla}} \wedge \vec{V}$ or $\vec{\mathbb{\nabla}} \times \vec{V}$. They are all correct.

Yes, I have MS office but the last time I booted my PC on windows 7 was 2 months ago.

Re: "Unified Revolution" new book by Espen Haug

I see the course book by Michel Rieutoord on fluid dyn uses (page 7)

$\vec Rot \space \vec v \wedge \vec \xi$,

At least you can separate scalars and vectors. But it can divert one's attention?
Schaum uses bold letters for vectors.

Re: "Unified Revolution" new book by Espen Haug

I just rebooted my machine to windows 7. I am getting the same issue with PowerPoint with the formatting. The same as I posted for LibreOffice.
I am able to export to pdf through File -> Save As -> Select PDF -> Save

Back to Linux.
