The Zeroth Law of Thermodynamics meme
Imagine being an equivalence relation. Couldn't be me
🤓
Yeah, math is the language model of our physical world. Math isn’t meant as base of the laws, but to express what happens in nature.
I don't think anyone nowadays would call this a "law", it is a property of some relations. (Fwiw I'm a mathematician not a physicist)
FWIW, I’m too dumb to understand any of thhis and don’t care if it’s dumbed down to my dumbness, cause I have tequila and pizza
generally people reserve comments for when they believe they have something to add to the conversation
That is not a law. That is a property of laws.
The zeroth law is transitive itself, but the law has nothing to do with transitive properties. It concerns the intensional properties of only two objects. The reason it is transitive is that less-than on reals is transitive and comparative temperature is measured using real numbers.
It's almost as if physics is based on math.
Enter Maxwell's equations
Holy hell
New theorem just dropped
It's almost as if physics is based on the Cenobite dimension from Hellraiser.
I get that reference…. sorry. 💪😂
Physics is based on meth
Two references I get today!! This has been a good day!!
You wanted to say that it's almost as if math is based on physics, right?
Our description of physics is based on math
This guy physics
Math was hired to do physics’ dirty work.
Physics is based on math.
Physics is described by math, many areas of which (but not all) come from needing new math to solve physics problems.
That's not true. Only very rarely has new maths been developed to solve physics problems. GR's mathematical basis had been around for ages before Einstein came up with it (actually, a mathematician had predicted GR, too). QM also didn't need "new maths" which had to be developed, they just used Hilbert spaces, which already existed at that point.
The only parts of maths developed for physics that I'll give you are (arguably) Newton's calculus and mirror symmetry.
Physics is one of the most common motivators for the development of new maths, but mathematics is not based on anything in the natural world. Math is deductive logic.
Why are they booing you? You're right.
The separation between math and physics is a relatively recent thing, before that math was just used to describe reality, and therefore math was just the language used to describe physics.
I wouldn't say "describing reality" immediately implies "describes physics". Linguistics describes reality, but has nothing to do with physics.
I would also argue that "maths was just the language to describe physics" wasn't true for most of history.
Maths predates physics. Most of what we currently think of as "physics" only came into being after Newton. Before him, there was mostly astronomy, which often included very little maths (besides Kepler).
For most of history, maths was mostly euclidean geometry. While it describes reality, it isn't "physical" (like linguistics).
The "maths describing physics" period was at most 85 years long, being the lifespan of Isaac Newton.
It establishes that temperature is transitive. A priori that does not need to be the case and cannot be proven mathematically.
Basically, it is not simply a statement of a certain relation, but the claim that a physical quantity obeys a certain relation. There's a difference.
The zeroth law of thermodynamics defines an equivalence relation based on thermal equilibrium, of which transitivity is one aspect
The Zeroth Law established the veracity of transitivity for temperature, as it can't be taken for granted that such transitivity exists until proven.
Please someone Explain like I'm 5
The Transitive Peoperty of Equality states that if two numbers are equal to a third number, they're equal to each other. If A = B and B = C, then A = C. The Zeroth Law of Thermodynamics states that if two objects are in thermal equilibrium with a third one, they're also in equilibrium with each other. If Temperature A = Temperature B, and Temperature B = Temperature C, then Temperature A = Temperature C. OP appears to be complaining that we had to write a law about something that "should be obvious," forgetting that sometimes reality hates our guts and picks the weirdest fucking ways to model itself. I'll leave it to more knowledgeable people to explain why it's non-trivial and really important, because it's been a long time for me and I'd fumble getting the ideas out.
ELI5 OP doesn’t know what they’re talking about
You guys should be in the hairdressing industry. All this hair splitting.!
If you believe that you haven’t understood the zeroth law of thermodynamics.
I don't remember exact reference rn but in schroeder thermal physics he refers to an article that shows that 0th law is not trivial at all
What is "transitive law in mathematics"? You mean like the transitive property that addition and multiplication have in real numbers?
Transitive Law????? OH, You mean the 1st Axiom.
it was introduced to me as “the zero with law, or the transitive property of thermodynamics”
i dont know what that mean i have a D in physics
Tf is "the transitive law in mathematics?" There are certainly relations which are transitive, but there is not (to my knowledge) one universal transitive "law", in fact, mathematics doesn't even really have laws, it has theorems
