Lightning in the main is electrons and ions.There is electrical energy in the brain, ions, electrochemical not photons.There's no electrical light energy in our brains?Also the colour you go when asphyxiating.Purple is a wisdom color.I think pain is the 'qualia' of nerve impulses.Pain is nerve impulses but what of the qualia of those nerve impulses?
Dunno why you say electricity is not photons.
I've never really understood the relationship between electrons and photons. I'm told that electricity is the flow of electrons through a circuit, however I'm also told that the electro-magnetic force is quantised (is that the right word?) by the photon.
next contestantThe electron is a particle which has a certain mass and negative electric charge. A particular electron exists at a specific position in space, travelling in a certain direction at a certain speed*.
If you accelerate an electron (eg if it passes close to a proton), it causes a disturbance in the electromagnetic field, which will propagate away from the disturbed electron at the speed of light. We call this propagating packet of energy a photon.
Electrons and photons both respond to the electromagnetic force, but they differ in:
mass: electron is 9×10−31 kg; photon is zero
charge: electron is negative, −1.6×10−19 Coulombs; photon is zero
speed: electron may be zero, or anything less than the speed of light; for a photon in a vacuum, it always travels at exactly the speed of light (a bit slower in denser media)
spin: electron: half; photon: 1
antiparticle: electrons have positrons; photons have themselves
For more, see: http://en.wikipedia.org/wiki/Photon or http://en.wikipedia.org/wiki/Electron
Besides electrons, other particles of matter like protons, positrons and mesons also carry an electric charge, and have a position and velocity in space. They differ in many ways from each other, but their electric charge also makes them respond to the electromagnetic force.
*Footnote: Quantum theory says you can't exactly know its position & velocity, but that's another topic.

Re: What is the difference between electrons and photons?

A photon is created when electrons return to a domestic state from a chaotic state. Valence electrons move from atom to atom, polarizing each atom and making them either positive or negative. When the electron moves back to its original atom and enters a domestic state, the electron releases a photon. I'm not totally sure why, but I hope that helped a little.
You can make any color look good. Value hue and saturation. There is no such thing as a bad color only a bad color scheme or interpretation of color.femaleonstage wrote:I have this theory that people who claim to love purple are actually seeing what I see as 'green'. That is the only possible explanation for anyone liking such a putrid, depression-inducing colour. People with purple houses are demonstrating an outward manifestation of insanity (unless they see it as green, which is not their fault).
