Can molecules/atoms store informations?

As far as I know, quantum computers work by changing the spin of electrons. Does that work?

Left spin = 1... right spin = 0

How our brain store the memories?
 
No our brains don't work that way. Well at least we know that much. All we know about memory in the brain is that it is some sort of complex pattern firing in the brain... but we do not know how that works or what makes it happen.

Found it. Well waddaya know? Wheeler and Feyman -

Which would explain why I read in a book - I grab everything I can find by or about RPF...

From your link;

"The one electron universe hypothesis, commonly associated with Richard Feynman, postulates that there exists only a single electron in the universe, propagating through space and time in such a way as to appear in many places simultaneously."

Can't it be thought that one prime force existed and exists which is complexed or concentrated in different shapes nd forms...somewhat alike for example, one big cloth got many waves, folds, knots etc.

Without such understanding, we may not be able understand memory part--which possibly could be there in all narural substances.

M-theory?

Or;

Big Bang
Unlike more conventional views of creation in modern physics, that are Ex nihilo, the M-Theory vision, although not yet complete, is of the whole observable universe being one of many super expanded 4 dimensional branes of an 11 dimensional existence. While branes of alternative universes exist "near us" their formulation of physical laws may differ from our own, as their number of dimensions. It is currently believed that a collision of "universe branes" somehow compacted enough energy to form what established physicists called the Big Bang.

Pls don'ttake isotopes in this regard as it may not be common to all atoms.

Pls tell more about different valence states in sense of storing the informations.

Well, many metals, like lead and chromium, have different colors for different valence states. They are commonly used to color paints. You could do something simple like writing down the information in different color paints or something complicated like using photodetectors and illumination of a particular wavelength. Again, all you need is a controlable difference and a means to detect it.

What is this:-

auxochrome
(Science: biochemistry) this is a group of atoms attached to a chromophore which modifies the ability of that chromophore to absorb light.

Retrieved from "http://www.biology-online.org/dictionary/Auxochrome"

chromophore
The part of a visibly coloured molecule responsible for light absorption over a range of wavelengths thus giving rise to the colour. By extension the term may be applied to uv or ir absorbing parts of molecules. Do not confuse with chromatophores.

"To understand M-theory it is necessary to first get some understanding of string theory. For hundreds of years physics has operated on the paradigm that the fundamental particles, like the familiar electron, are point-like or (in mathematical jargon) 0-dimensional. If string theory were to be summed up in a single idea, it is that this assumption is incorrect. Instead, string theory posits that the Universe is fundamentally composed of 1-dimensional objects—things that are similar to a string. These strings would be so small that on even the tiny scale of particles they would seem like points. In string theory, each fundamental particle is created in some sense by different patterns of vibration of the strings."

In theory, all the 4 forces are particles.. which are made by different vibrations of the strings.

String theory
http://en.wikipedia.org/wiki/String_theory

It tells aboute infinite numbers of strings. What create vibrations in these? How vibrations can create particles?

There can be two aspects; "prime force" and "prime particle/s. There can be secondary forces and particles which may look to us as fundamental or elementry, probably as we couldn't yet measure/know the prime force/particle. These should be somewhat "omnipresent" --may be in some complex form at visible/measurable levels. "Point" form seems to be more valid in view of "omni" properties. Other thought may be just one force(or whatever you name) spread everywhere and its complexing--folding, knots..somewhat alike waves, bubbles in swiming pools etc. is current visible or measurable things.
 
"Point" form seems to be more valid

As I understand it string theory was introduced because of severe prblems with "points" - If it's a point then it must be either massless or of infinite density...

It was introduced when trying to find a formula to explain the strong nuclear force... fiddling with this function suggests strings that vibrate in multidimensions.
 
Thanks Absane. Damn. The older I get the more out of touch I get...

For some reason I always had a sense you were in your twenties. I guess not :p
 
Thank you kind sir. I was fifty at the start of the year...

Yes but can't points complex into strings?
 
Not as far as I know. I think (only think) that the strings are assumed to be the smallest thing you get, and their vibrational pattern determines what type of particle they are... very hazy. But points are a non-no AFAIK, due to infinities (renormalisation? help me out somebody).
And strings don't break, otherwise they just "disappear" rather than become a broken string.
 
>>And strings don't break, otherwise they just "disappear" rather than become a broken string. <<

It may be due to that "points" may not be measurable or indescibable.
 
Someone informed that spins and spectural lines(non chemical reaction based) can vary and persit as information by keeping any substance in "magnetic field"?

Whether other substances than ferro magnetic in natural, individual or diluted atoms/molecule form possess some magnetic field or not which may effect in above manner?
 
Every substance should be having some specific vibrations, temperature etc, so some magnetic field or other energy fields. Keeping one substance in close contact with other subsance can ater its spins and spectral lines--though minutely below emission or reflection level. Till those two substances are persists in close contact such changes can persit as information to each other.

Is it ok?

What do you name to energy fields existing in substances other than ferro magnetic material?

Will such energy fields be effeted by keeping two substance nearby or in close contact and persist as information till such contact in maintained?

Will such energy fields be enhanced on dilution or individualization of one substance out of these two?
