What is length? In this context, a length is a pointless time string (see other related posts).

What is a pointless time string? It is the integral or sum total of finitely large number of time axes pointed inward to a center of a spherical symmetry. Once this symmetry is achieved, a real volume is formed. If this volume is attached with a density function then mass is defined as the product of volume and density. It is logical that a differential length with a time axis can be integrated into a closed surface. This closed surface defines density using the divergence theorem of vector analysis.

What is the divergence theorem of vector analyse?

[AntonioLao]

GUILLE,

For divergence theorem, see

This theorem is used twice in Maxwell's equations of the electromagnetic field: the source of the electric charge density and the nonexistence of magnetic monopoles.

the inverted triangle is none other but the del operator of vector analysis. I invented an inverse operator called the ta operator.

In what is your invention usefull? (I don't try to offend, but mathematical developments should only be there to fight problems).

GUILLE,

When it operates on the frequencies of waves, the result is velocity.
