It's the other way around.

It takes my breath away how consistent the mean length of a day is and how accurately we can measure it. So accurately that if it deviates by mere tens of milliseconds, and it does, we can notice it.

It boggles my mind that a hunk of rock made up of differing densities, with so much of salty water sloshing around, Moon exerting her brakes, bombardments by extraterrestrial matter, Earth still remains so consistent. Of course, this is not surprising if one does the math.

Yes math and physics are different. It's the the fact that math can model the physics so accurately at all that it's breathtaking.

ha ha ha!, we state the same thing, I think, maybe, but it's the "10's of milliseconds" of inconsistancy that I am refering to, we can measure things in as you well state, a "breathtaking" way, but are then reduced to bieng reality's mad, overworkered, note keepers, and ALL of the clocks are still ALWAYS wrong, with the very definition of time becoming something that we must descibe as "realitys ongoing mistake, that we must correct for". I will indulge myself and go a bit farther into woooooo, teritory, in that this new ability to keep time so accuratly is something that resists entropy by creating order, where there is none.

  • Frankly there is nothing woo about it.

    Even without venturing into the realms of Quantam Mechanics or Chaotic Dynamics, all measurements are, by physical definition, upto the resolution of the measuring instrument. So it always come with inherent +/- error bars. Sometimes these error bars are made explicit, at other times they are elided, often with the assumption that it's obvious.

    Models are always simplifications. That is precisely why they are useful. ( A 1:1 scale map is not very useful, especially when we already have one). Models are obtained by ignoring the effect of many known disturbances, but whose effect one deems not to exceed a tolerance bound.

    • I am thinking more about time, and the ability to sincronise two signals, and say with an analog signal, and a digital time stamps, simply combining the signals 180° out of phase and getting zero verifies the accuracy of both, which is I assume is my crude beginings on modern encryption, and that gives our data the power to resist,entropy. So can we then reverse entropy by encoding information into everything? woooo!
