Phenomena around us made possible by electrons

Almost anything really.


Here are a few examples:


Floating in water.
Electrons on our body repelling electrons of water.


Airplanes dynamically floating on air.
Electron on the plane repelling air electrons.


Friction. Electrons ripped off. This is why we may see sparks.


Seeing.
Electrons vibrating at the sun make electrons on earth vibrate too and then the electrons in our eyes vibrate too when we watch those objects.


Seeing our self in the mirror.
Same, the mirror is metal coated behind the glass. Jealous electron mimic exactly what the electrons on our body do.


Music information traveling from the transmitter antenna to the radio antenna.
Jealous electrons in the radio antenna imitate the dance of electrons of the transmitting antenna to music.


Electrons remembering their orbit creating magnetised domains on analog audio tape or digital data hard disks.


Touching someone. Atoms cannot touch each other. It is the repealing action of electrons that get close and repel each other when we are touching. Like the same poles of magnets being approached. Knowing this does not reduce the mystery. Hugging also involves heat transfer from one body to the other by convection, conduction and radiation (jealous electrons again).


Energy transmition from our sun to us. Electrons on the sun move in all sorts of very quick ways and vibrations. When the electromagnetic wave traveling at the speed of light arriving makes jealous electrons on earth imitate. And flowers look all kinds of colors. Everything is heated up as molecules and electrons increase their average speed... We may also say that packets of energy called photons travel from the sun to earth at the speed of light.


When we rub for example amber it then attracts small pieces of paper. It becomes charged by electrons being ripped out from one of the materials. Amber in Hellenic is called Ηλεκρον. And this is form where the name electron and electricity comes from.


Electric current is the flow of electrons.


Microphones convert the vibration of molecules carrying the music information signal to vibrations of electrons carrying the music signal.


Then we can do all sorts of things utilizing the property of electrons repealing each other or the fact that they are jealous.


For example:


Sending the music signal at the speed of light through the mic cable full of free electrons to the amplifier. Amplify the signal by electron tubes or transistors. Store the music signal in magnetic tape or disks or flash memory etc. using electrons. It is not the electrons that move at the speed of light. It is the wave (one electron repealing the other) ie the transfer of energy that moves at the speed of light.


Don't they ever get tired?


Stationary electrons create electric fields.


Moving rake tries magnetic field.


Vibrating electrons create electromagnetic fields. When another electron in the universe is met by this electromagnetic field it vibrates too (the jealous part).
