I don't think anybody is coming up wth all these dimensions through a process of thought experiments or intuition. THey're running some equations and out pops a number. Sometimes 10, or 11, or 26.. etc. I doubt there's a formal definition for any of the dimensions past 5.

Not really formal definitions... they are defined by the equations they're in.

Exactly; they're retro-fitting the data to fit the equations, so to speak. Not exactly proven under the scientific method yet. Good hypotheses, but not very tested nontheless. They're more a conceptual model, if anything. Not Reality, if you ask me.

Ah, yes, AL... but then, what IS reality? :biggrin:

Humans can't really define that, Kent! So, our perception is reality enough to us humans (so long as you're always willing to change your perceptions). That's what I says.

I don't know if any of you have read it but Laurence Gardner has written a book, 'Lost Secrets of the Sacred Ark' and in it he says that “the Ark of the Covenant has its final resting at Chartres Cathedral.” (Chartres, France) That the superconducting nature of the Ark allowed it to move into a “collapsed six dimensions, or through a portal into fully expanded dimensions”, into what Gardner refers to as “the Realm of the Orbit of Light". Considering the extraordinary characterisitics of Superconductors, this scenario is well within the realm of possibility.

Well, yeah, I suppose. But that sounds too much like sort-of-science to me, MP.

I'd want to take a look at the Ark's schematics.

Well - yes - he make make it seem like 'sort-of-science' but look at the physics behind it. The diamagnetism of the superconducting state is extraordinary in that it expels from its interior any external magnetic field up to a limiting critical magnetic field strength. In as much as it takes energy to expel a magnetic field from a superconductor, a magnet can under the right circumstances float freely above a superconductor at the point where the upward force generated by the field-expulsion energy balances the downward gravitational force. This magnetic Levitation becomes even more fascinating when one recognizes the Earth is effectively a magnet, and that a superconductor (obviously being of somewhat less mass) could thus reverse the roles and float freely above the Earth. (sorry for rambling and side tracking - this is what happens when i talk physics - my mouth - or in this case fingers - spout uncontrollably :D ).

The BCS theory describes a pairing of conduction electrons by some interelectron attraction and a condensation of these pairs, “Cooper pairs”, to form a macroscopic quantum state. The superconductor’s electrical resistance is zero because the Cooper pair condensate moves as a coherent quantum mechanical entity, which atomic lattice vibrations and impurities cannot disrupt by scattering individual Cooper pairs in the same manner they scatter single conduction electrons - the latter being the reason electrical circuits have resistance. How the Cooper pairs are formed is obviously a critical factor in superconductivity. One theory is an electron passing by the crystal lattice of atoms in the conductor distorts the lattice in such a way the next electron is attracted to the lattice distortion. Or instead of the electron-pairing being mediated by lattice vibrations, the interaction of the conduction electrons may be due to charge or electron spin fluctuations in some electronic subsystem. From other aspects and theories of physics, we derive the concept of an electron consisting of an infinitely conducting shell, one with a minute magnetic field (i.e. a superconductor with Meisner Field). Spin adds the critical ingredient of maintenance of the magnetic/Meisner field, while fluctuations (at the level of Heisenberg’s Uncertainty Principle) connect via Hyperdimensional Physics. It is this that leads to believing the scenario is well within the realms of possibility.

float freely above a superconductor at the point where the upward force generated by the field-expulsion energy balances the downward gravitational force....

a pairing of conduction electrons by some interelectron attraction and a condensation of these pairs...

atomic lattice vibrations....

the electron-pairing being mediated by lattice vibrations, the interaction of the conduction electrons may be due to charge or electron spin fluctuations...

You make it all sound so -- erotic.

Can I come over and try this with you??? :devil:

And this is exactly why it's so hard for women to be taken seriously in physics.

There is a wonderful poem by the great mathematician, James Clerk Maxwell, which i love and which seems rather fitting:-



Oh WRETCHED race of men, to space confined!

What honour can ye pay to him, whose mind

To that which lies beyond hath penetrated?



The symbols he hath formed shall sound his praise,

And lead him on through unimagined ways

To conquests new, in worlds not yet created.



First, ye Determinants! In ordered row

And massive column ranged, before him go,

To form a phalanx for his safe protection.



Ye powers of the nth roots of - 1!

Around his head in ceaseless cycles run,

As unembodied spirits of direction.



And you, ye undevelopable scrolls!

Above the host wave your emblazoned rolls,

Ruled for the record of his bright inventions.



Ye cubic surfaces! By threes and nines

Draw round his camp your seven-and-twenty lines-

The seal of Solomon in three dimensions.



March on, symbolic host! With step sublime,

Up to the flaming bounds of Space and Time!

There pause, until by Dickenson depicted,



In two dimensions, we the form may trace

Of him whose soul, too large for vulgar space,

In n dimensions flourished unrestricted.”
