Such is the case encountered in the attempt to unify general relativity and quantum theory, since they are expressed in differential geometry and functional analysis, respectively. That being said, spectral geometry a field in mathematics which concerns relationships between geometric structures of manifolds and spectra of canonically defined differential operators may resolve this long-standing quandary by allowing spacetime to be treated as simultaneously continuous and discrete, essentially relating the frequency-based ringing of the fabric of spacetime to its manifold-based shape.

Oh Yes !!!!!!

Funny, someone said exactly this down the pub last night. What are the chances of that?

Infinitely improbable I'd say, therefore it almost certainly happened...

Well, how about that? No threads about physics on Pprune for years then 3 come along at once - got to be at least 5 standard deviations off the mean there!

Reminds me of Richard Feynman in a cab to the airport in NY to pick up his Nobel Prize in Physics. Cabbie says
"Can you tell me in simple language why you're getting it?"
thinks
"No. And if I could, they wouldn't be giving it to me."

I thought up time and relative dimension in space but then discarded it and went and bought a police box.

You've got it back to front.. and it is a question not a statement...

Shape based manifold, is its (to space-time of fabric) the fringing based frequency, the relating, essentially discrete and continuous, simultaneously as treated, be, to space-time, allowing by quandary long standing, this resolve may (operators differential defined) canonically of spectra and manifolds, of structures geometric (between relationships concerns) which mathematics- in a field geometry differential, in expressed, are they, (since theory quantum and relativity) general unify to attempt, the in encountered case is... such?

Which, if you think about it, is exactly, erm, more or less, what I've been saying over the last ten years on that forum and on PpuNe.

In my book shelves, I have 3 copies of Hawkins book. In each copy, the bookmark is at page 15.

So 42 works for me, too.

After reading the Op's opening post I have decided that in lieu of a migraine or head-throbbing headache (after reading all that) I will opt instead in consuming copious amounts of beer. That should allow me to better understand WTF he wrote. :}

I can see where you're coming from here ExRAFR, but don't forget; what is the main obstacle in the way of uniting the four forces and all of the elementary particles? Well, remember that what physicists have been trying to accomplish is the uniting of the microcosm and the macrocosm. These two areas of cosmology are represented respectively by quantum mechanics and general relativity. In the case of quantum mechanics, we have a world that operates on uncertainty, probability, and complimentarity. If we could look through a microscope at this tiny universe, we would see random quantum undulations resembling something looking like a storm on the North Atlantic Ocean. If we took this into outer space, into the smooth gravitational field of a planet, you would no longer have the smooth warp of space-time described by the spatial geometry of general relativity.
Just about sorts it out wouldn't yer say? :\

As in weird numbers. Bistromath derives from the knowledge that the number of people who will turn up at a table is any number except the number who booked. All other randomness follows. Deciphering the check requires a PhD in hypermathematics and 3 years, so it's easier just to add $20 to the total, ask everyone for an even share, then chip in another $20. The accumulated cash will always be $20 short for no apparent reason.
