Default Virtual photons and the electromagnetic force.

Braggart.

First off, it's said that bosons with spin 1 mediate repulsive forces
and bosons with spin 2 mediate attractive forces.


Who said that? Nobody. Virtual photons mediate an electron and a
proton attracting (ortho- or para-hydrogen) as well as two electrons
or two protons repelling. Ditto positronium binding, singlet or
triplet. Name a spin-2 boson other than the problematic graviton.

A photon is spin 1.
So, how does it mediate attractive forces?


Google, library. Do you suspect that your question has not overturned
all of physics?

[snip]

Also, there are two perpendicular waves carried by the photon.


Very Badly Put.

The
electric wave and the magnetic wave. However, there are two distinct
ways that they can carry this pair: right-handed and left-handed.


Crack a book on optics. Please. You don't know squat about elliptic
polarization.

What
relevance does the handedness of virtual photons have to the mediation
of the electromagnetic force? Do negative and positive charges react
differently to the handedness and emit photons with different
handedness?


An electron has helicity not chirality. Learn (Uncle Al the optimist)
the difference between axial and polar vectors. Even an idiot can see
that a right-handed spinning ball viewed from its north pole is a
left-handed spinning ball viewed from its south pole. The thing is
only chiral if it is relativistic and you can't get around to the
other side. High energy beta rays from nuclear decay are all
left-handed. Low energy betas merely have helicity. It was essential
that

was done with Co-60 and not H-3.

[snip dreck]

Crack a book.

I know I like to be a 'know it all' but I really don't know as much as
I like to pretend... so please hear me out.

How am I a braggart? I'm just asking a question. You're the one being
a braggart, pretending you know so much when you can't even explain it
to me in English. Obviously you're just parroting what other people
have said, and have no idea what you even mean by what you're saying.

First off, it's said that bosons with spin 1 mediate repulsive forces
and bosons with spin 2 mediate attractive forces.

http://scienceworld.wolfram.com/physics/Boson.html

There. That's who said it.

Virtual photons mediate an electron and a
proton attracting (ortho- or para-hydrogen) as well as two electrons
or two protons repelling. Ditto positronium binding, singlet or
triplet. Name a spin-2 boson other than the problematic graviton.


I really can't. Do two photons count?

A photon is spin 1.
So, how does it mediate attractive forces?


Google, library.


What do you mean? Google has a library?

Do you suspect that your question has not overturned
all of physics?


A question can have no effect on physics.


[snip]

Also, there are two perpendicular waves carried by the photon.


Very Badly Put.


Well then how should I put it? There are two orthogonal transverse
electromagnetic oscillations?

The
electric wave and the magnetic wave. However, there are two distinct
ways that they can carry this pair: right-handed and left-handed.


Crack a book on optics. Please. You don't know squat about elliptic
polarization.


No, I'll explain it. Assign directions to the electric component and
magnetic component of the oscilation. Then take the cross product. The
two possibilities are that you will get something the direction the
photon is traveling or that you will get something opposite of the
direction the photon is traveling. That's what I mean by 'left handed'
and 'right handed'.

I'm sorry, I should've phrased it better.

Also, what do you mean by elliptic polarization and what does this
even have to do with the current argument? And please answer the
question in English, not in Bizarro Uncle Al speech.

What
relevance does the handedness of virtual photons have to the mediation
of the electromagnetic force? Do negative and positive charges react
differently to the handedness and emit photons with different
handedness?


An electron has helicity not chirality.


I think you may just have this backwards.

Learn (Uncle Al the optimist)
the difference between axial and polar vectors.


One changes and one doesn't.

Even an idiot can see
that a right-handed spinning ball viewed from its north pole is a
left-handed spinning ball viewed from its south pole.


But what if it's spinning while it's being dropped? Then the north
pole and south pole DO make a difference!

The thing is
only chiral if it is relativistic and you can't get around to the
other side. High energy beta rays from nuclear decay are all
left-handed. Low energy betas merely have helicity. It was essential
that

http://physics.nist.gov/GenInt/Parity/cover.html

was done with Co-60 and not H-3.


You are very bad at explaining things.

Shut your crack hole.

I like to pretend... so please hear me out.

The original phrase to what?

Now you're just messing with my head.

Stop speaking like an idiot.

Oops, I guess you have no control over that, do you?
