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‰.

1^st^ law of thermodynamics :
There is something that will always be the same.

Everything else always changes and never will be what it was before.

A closed system is closed because all of the edges aren't open.

I think you are misquoting the laws of thermodynamics.

https://en.m.wikipedia.org/wiki/Laws_of_thermodynamics

It's very important to understand the rule and the implications. It's self-consistent. They are axiomatic, so if you can come up with a better system that and demonstrate it you can beat it. But until then they're laws.

My misquotation was on purpose.
in the same thread of thoughts : if there was a system without the first law, anything could appear as if by magic !
...that is, until the 1st law appears.

It sounds like you're confused on what a natural law is. They do not prescribe the behavior of a system, they describe it.

The first law is a law because our observations state that all systems obey it, not the other way around.

What you're saying is "If there was a system that behaves fundamentally differently than every system yet observed, then it would not follow the laws of thermodynamics." Which is kind of the point.

On a side note :
is there something in nature that prescribes the conservation of energy ?

(please, if you answer this, do so under my other comment (big bang...) ...I don't want to lose track of the main topic).
