What is Heat? What is a Car Brake? What is friction?
The words friction and heat are equivalent to the word ignorance. We use single grand words to describe processes we do not understand. If we actually understood heat hundreds of years ago, we wouldn't have needed Robert Brown and Einstein to give us their notes on Brownian Motion.
Brownian motion is evidence that kinetic molecule movement is unified with mechanical movement of a microscopic object, however we still haven't clued in on this basic fact and developed the technology to exploit microscopic movement. Hence the birth of Olson's Brownian Motion Interference discovery.
Heat is an illusion in our nerve endings and we call it heat because we are dumbfounded by our nerve endings and neurons in our brain giving us a feeling of warmth. Heat is actually microscopic movement, and the word heat blinds us in stupidity. Something that is hot feels that way to the observer, but is it actually warm in nature objectively? (a truly objective scientist has no nerve endings, has no feelings, has microscopes on his eyes, and does not fully accept that a wife or husband causes him or her to be warm when held).
We observe friction as a nuisance and do not really know what friction is. It produces heat but why? Is friction just another version of eddy currents when two objects interact electrically at a surface? Is eddy current electrical friction in wires and metal whereas friction is eddy current in all sorts of materials? The word friction dumbfounds us, just as the word heat dumbfounds us.
When a vehicle is moving at tremendous speed, it has kinetic energy. This kinetic energy can be transferred into microscopic movements, which is what brake pads cause. Essentially a car brake is converting macroscopic movement into microscopic vibration and jiggling, which has the illusion of being hot. If one were to use an extremely powerful microscope to inspect a brake disc and brake pad while it was slowing down a car, the microscope would detect and show kinetic microscopic movements of molecules increasing.
Eddy currents have the advantage of producing heat without loss of material, whereas brake pads slowly lose material as dust over time. If a vehicle is passing by a wall and not touching the wall, eddy currents can be produced without any material loss like in a friction design. This begs the question: is friction a similar process to eddy currents since friction essentially produces hot spots very similar to eddy currents.
