What is half a spin? - 11-04-2005, 05:59 PM

I am not trained or educated in this specific area, so forgive my ignorance.

What is half a spin? As in a sub atomic particle with a spin of 1/2?

This sounds interesting but I cannot understand this in tangible terms.

Spin is a word I can apply to a ball. Clockwise or anticlockwise, viewed from opposite sides.

Is half a spin some different form to clockwise and anticlockwise and stationary?

I want some tangible idea if this is esoteric, or how it relates to the reality that we make in our minds from the sights sounds and sensations we experience as human cognition.

Thanks Antonio - as my focus currently is on neutrinos, specifically, I want a very clear idea of their motion. Neutrinos apparently oscillate between different forms and weights, how do they spin in all of that? If their spin is in some way neither clockwise nor anticlockwise, are there transitional moments of standard spin or being technically stationary.

if mass is somehow consistent motion within a frame of reference, how does rotation in its various forms "become" mass?

And my other interest is the magnetic monopole - I have this image of half a magnet, very small, spinning or twisting but half of that magnet is not here. Is it somewhere else? Does time spin etc... (well I think time does not exist, only the now, but that is another topic...)

I have no idea what the phrase "odd and even quanta of space time" means. I am boldly - perhaps foolishly we will see - making a new definition of material reality to contrast against consciousness. Simple evident rotation is the fabric of reality, so spacetime is indivisible into space or time, rotation is both and there can be nothing but rotation (material form) and stillness (consciousness), and the vortices where these juxtapose.

In the quantum domain, spins are manifested as the changes of energy levels as observed in the spectral lines in the experimental science of spectroscopy. Since quantum spins are discrete, they only have two possible values, say 'up' and 'down' of Planck's constant divided by 2pi. The following site gives information about the connection between specific heat and the Bose-Einstein or Fermi-Dirac statistical distributions of quantized energy and spin.

So spin for a nuetrino is an esoteric concept, a collusion of academics licking each other's ... ice cream?

Do neutrinos spin in the sense that a ball spins?

No, apparently this word "up spin" or "half spin" is used poetically when a measurement we do not understand is observed on a machine.

That is esoteric.

I realise the concept of sub atomic particles or things is fairly esoteric anyway.

Is there some sinewave oscillation and if so what is the rotational frequency and amplitude?

Or is spin just a word, it could easily be "twist" - if it is - as you imply - static. Or "offset". What quality of the mundane dog and ball and child experience we all know as "spin", IF ANY, applies to the "half" spin or "Up" that is real, out there, beyond the read out on a machine?

Don't Bose make loudspeakers? Fermi-Durac sounds like a cream French people put on cuts and bee stings.

Thumping the table here, in the realm of sights sounds and sensations, when the library is closed, and all the books are burnt...

When the temple is shut and the priests have no bibles, no quoting and avoiding, what IS spin?

When the politician has not answered the question, the TV presenter repeats it. Here in the UK.

Confident that you will forgive my frustration in good humour Antonio, you have been kind to reply, forgive me, I did not find anything my fingers could touch, my eyes could see without a machine, my ears could hear without language, I declare I am really frustrated that you avoid the possibility that these things are real, and if we could be at the these tiny scales, what would our human senses encounter?

spin is change in energy - 11-09-2005, 01:17 PM

Spin is the change in energy say from red to orange to yellow to green to blue to indigo to purple. If this change is continuous, then all the seven colors can be seen. But if the change is quantized, only certain colors can be seen. This is what is happening at the quantum domain of reality, that is not all colors can be seen at the same time. And it is the same shifting of colors toward the red or the blue that determines the recession and precession and accession of galactic circus.

Mike,

the following sites show some animation about internal rotations within a sphere. Just thought you might enjoy them.

there r particles that do not look the same if one turns them through just one revolution . u have to turn them through two complete revolutions such particles r said to have spin 1/2.

Hi maights...
I have the same info as mohammad said, and from the same referance(A Brief History Of Time BY stephen Hawking)
its easy, particles as you know divided into two types as thier spin:
1.Fermions,have halfs spins,means 1/2,3/2,5/2 and so on..while
2.Bosons: have integer spins,0,1,2..

What do the numbers mean?
particles have shaped as we know, now if you want to see the particle in the same first sight you see in you must turn it by spacific number(my english horrbile, i kno)
e.g photons: are bosons have spin equal 1, it means you must turned it 1 complete revolution to look like the 1st sight you saw..
if spin equal 2 you must turned it by 180degree(half complete revolution)..

like electrons: its fermions, have spin half;it means you must turned the electron tow complete revolutions(720 degree) to see it in the same shape again!!..


what about prticles which have spin equal zero??
this number means that this particle looks same from all sides, like POINT!!; seems one from all directions..


do you understand now? i hope that..
Best regards
Ema

Spin is related to the actual TIME we have the ability to say: "Hey there is a "particle" here and now." Once that particular spin changes in angle [during its trajectory] we may loose it or keep watching it and that "thing" we recite from official books as a "given phenomenon" with no plausible justification is what we call "spin."

Spin is [as I see it] the physical manifestation of a physical occurance called "standing waves." If two waves interact each other in space they will produce a phenomenon called interference... after all they are waves and waves have the ability to behave in a different way than "compact particles of the macroworld."
Now imagine that instead of looking at a stationary process of the making of standing waves in a fixed point in space we were looking progressively as two interacting waves move across space producing intermitently the same effect described above...
Think of this it couldn't be easier for all of you:
All waves carrying some degree of energy are said to "move" at "c" right? ok.
If two or more waves were moving in the same direction and on top of all that being somehow "physically attached" which in the official language means "entangled" >>> couldn't be possible to state that "those particles" observed as the result could have a weird existence?
The latest researches in neutrino have confirmed the existence of a unexplained phenomenon called "oscillation."
It means that the ACTUAL existence of those "particles," once predicted by Pauli in the past while trying to understand how netron's decay, have the ability to "change their identity" as the [complex] wave goes on.
Half spin means logically half of "something" that gives us the reassurance of the existence of a piece of "matter." [we chose to call "particles"]
I do not believe in half terms anyway. We humans tend to assume that if something is said to be contained in a unit of space that thing could and must be divided in two halves to make sense... nonsense!
A magnetic pole is the resulting amplification of a standing wave process of integration at atomic and molecular level. You must have both poles since spin means a trajectory that always returns to the same starting point... can you see it?
Is it possible to "mask" one phase of spin? Of course it is! Molecules do that all the time. Once a bond between two atoms is stable there is no further need for that specific atom to "search" for other bonds... unless there was a chance to achieve a better stability while chosing another "partner."
This is what chemistry is all about. A permanent adjustement of stability between unstable bonds. All matter is at some point unstable and prompt to change bonds as needed. The instability is part of the nature of matter itself. Since for me matter is nothing but the manifestation of bonding energies and the resulting interactions [standing waves of colliding high energies] there is no possible way to obtain a perfect couppling between two atoms in a bond. The vibration observed in every single atom is due to the internal nature of matter and its spinning or cyclical instability.
When I speak of instability I'm reffering to the nature of the spin itself and not about the presence of elements on nature... do not misunderstand me.
To make a simple example of what I'm saying:
If you make a magnet to rotate of simply move across a wire you will obtain a flow of current. For a static magnet current will be zero. Atoms act the same way. it is their vibration what allows them to "feel" the needed attraction allowing them to bond and stay that way...

Anyway... It sounds simple but it's not I guess.

HBD
