Setting aside for a moment your (purposeful?) mistaken rendition of 2 of the 4 Laws...

I like to characterize them this way:

  • 0th Law - Everyone is playing this game (definition)
  • 1st Law - You can't win
  • 2nd Law - You can't break even
  • 3rd Law - You can't quit playing

These aren't rules some entity has given us. As best we can determine, these just describe the way the universe works as regards energy. But instead of everyone having to discover them over and over or in every new proposed application, our Very Smart People have discovered them and recorded them.

I don't see anything in there that's along the lines of "this is true because it's true." The laws of thermo aren't provable except by observation, because they are the first principles. If there were first principles from which we could derive the laws, those would be the laws.

That's not to say they don't exist, because they might. We just haven't found them yet, if they do. I have gone through the mathematical foundation but I'm on the fence as to whether that counts as a "first principle" since it has a sort of "chicken & egg" problem.

There is no such thing as a Stupid Question!

Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.


Reminder that the rules for lemmy.ca still apply!


Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐Ÿ‰.
