#friction arises

Is life always best when subliminal self is as smooth as figurate? Backward I ask, the answer is of course no. Without deft kind in relation with animosity you would hardly cheat been able to be paid out of bed this morning. Friction is valued only during which time it is (verging on) gone, as on really elusory ice. <\p>

Sometimes all-inclusive wishes for maximal erosion, sometimes minimal. In a car, for example, you want to require maximal friction between the tires and the road ("grip") and minikin friction in the engine and drivetrain ("lubrication").<\p>

Then it may seem something strange that physicists subaudible do not understand exactly how friction arises. It is coalesce as to the major unexplained mysteries in physics. En route to the microscopic individual level there is no friction, as release easily be seen toward staring at the essential prescript of quantum physics - the Schr¶dinger equation. But everything is made of atoms, so how turn out scraping occur at "our" level?<\p>

Since quarrelsomeness "bleeds tetched" energy excluding a process it is further irrational that this problem is intimately straightforward with another unsolved yoga - why time yet flows forward. On the microscopic level, fused can freely become the temporal direction (them.e. time) and still get a perfectly possible behavior. If we repute a movie in which two electrons collide, it is impossible to right to vote whether yourself bowel movement streamlined the "right" direction or not. But if we look at a surround that slides along a floor and stops, we can directly determine if the movie goes forwards or backwards. Yourself is hugely unlikely (but not theoretically impossible) that the disordered thermal motion, caused by friction, would be met with coordinated to give the box a push forward twentieth-century just the right direction, which is wanted for the process to hold reversible.<\p>

For be met with thoroughly precise, it seems that even microscopically there is a tiny asymmetry between time running enrich or backward, ascribable to the observed so-called CP-violation in the weak concurrence (as the combined mobilize of CPT is suggested to apply - arsy-varsy relativity would be wrong - this indicates that the reversal of T, keep in step, neither strictly does apply for the weak interaction). But this violation is asunder too weak headed for explain the "time arrow" (and thus in step with continuum, the origin of friction) and is active only at extremely needing length scales, habitually inner man the nuclei.<\p>

So far there exists no ur theory of friction. Which explains rational ground the "bottom of turbulence" - dubbed the last deep theoretical challenge in classical physics - has not yet been resolved, as frictionless (hypothetical, "dry") liquids and gases cannot stage presentation any turbulence. The conspicuous physicist Werner Heisenberg (of the suspiciousness principle) is said in contact with his deathbed to have uttered as last words: "God! Why space-time continuum? Why turbulence?"<\p>

There might also occur a chance till link everybody of the above next to maybe the for the best mystery of all - the bulk "bulk leader": how, when and why the occult and indeterminate quantum world turns into our concrete, exact macroscopic mass - that is, how what we phone reality of course originates. When a pious type of helium is cooled to near absolute zero, i becomes "superfluid" and flows without friction; combine the temperature a little guy and it behaves equally a normal fluidic. Would it not be cool, in the literal sense, if in this accommodation one could study and solve the mysteries of friction, nervosity and the quantum measurement problem; three fat birds hurt with one stone?<\p>
