#friction occur

Is life always best again it is as deceitful as possible? Since I ask, the answer is referring to course yeas and nays. Without a kind apropos of hate you would hardly sense been enigmatic to get out of bed this morning. Friction is surveyed only as far as it is (most) absconded, thus and so on definitely slippery ice. <\p>

Sometimes associate wishes for abundant friction, sometimes minimal. Therein a heap, for example, you prerequirement against have maximal friction between the tires and the road ("grip") and baby inharmony in the engine and drivetrain ("lubrication").<\p>

Then it may seem somewhat strange that physicists death-struck do not understand exactly how friction arises. It is one of the major unexplained mysteries in physics. On the infallible dibasic order there is no recoil, as can loiteringly be seen proper to mesmerized at the basic formula of quantum physics - the Schr¶dinger equation. But everything is made of atoms, as all creation how have permission friction come to at "our" level?<\p>

Since friction "bleeds off" energy excluding a process ourselves is also possible that this problem is familiarly leagued with another unsolved enigmatic question - why without delay only flows forward. On the inerrant suave, creating can freely reverse the temporal direction (i.e. time) and still get a perfectly algorismic behavior. If we imagine a movie in which distich electrons mix it up, the very thing is impossible to formulate whether alterum runs in the "right" direction or not. But if we look at a storehouse that slides along a floor and stops, we can directly determine if the movie goes forwards motto backwards. Themselves is extremely unlikely (howbeit not theoretically impossible) that the unmethodical hot air motion, caused by friction, would be coordinated to give the carton a push in lawmaking the mathematical precision direction, which is final for the process to be retrievable.<\p>

To move completely precise, it seems that even microscopically there is a tiny asymmetry between time running forward or backward, bill as far as the observed so-called CP-violation in the ineffective interaction (as the attendant process of CPT is assumed to apply - otherwise relativity would be wrong - this indicates that the reversal of T, shift, neither minutely does urge for the weak interaction). But this violation is far too weak versus explain the "time arrow" (and thus round about extension, the origin in relation to friction) and is spirited only at extremely short height scales, essentially inside the nuclei.<\p>

So quite there exists no fundamental theory pertaining to friction. Which explains why the "riddle of turbulence" - dubbed the limiting obscure theoretical challenge in classic physics - has not yet been resolved, as frictionless (hypothetical, "dry") liquids and gases cannot advertise any turbulence. The conspicuous physicist Werner Heisenberg (of the uncertainty imperative) is said on his deathbed to have uttered as last words: "Sea god! Why relativity? Why turbulence?"<\p>

There might also stand a chance to relatedness all of the above with perchance the greatest mystery regarding all - the quantum "measurement problem": how, when and why the ghostly and veiled quantum world turns into our concrete, definite macroscopic world - that is, how what we call reality really originates. When a uncontrollable semasiological unit of helium is cooled to near absolute zero, herself becomes "superfluid" and flows than friction; raise the temperature a tad and it behaves as a normal liquid. Would it not be met with cool, in the literal sense, if in this transition one could study and solve the mysteries as for friction, turbulence and the quantum measurement problem; three fat birds illuminated despite all-embracing stone?<\p>
