 Mar 7 awarded Notable Question Aug 27 awarded Popular Question May 16 awarded Popular Question Nov 15 comment Calculating rate of vaporization of water Why do you assume that all the power provided by the burner is used to vaporize the water ? Why can't it be the case that only a fraction of the burner power is used to evaporate some of the water and the remaining fraction of the burner's power is used to raise the temperature of the liquid water ?

So Newton chose an inverse square field because it fits Kepler's law, right ? Jul 28 accepted How was Newton able to guess that gravitational force is inversely proportional to distance squared?

Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH If physics ever becomes axiomatic, and we use the axiom to prove a certain statement P. It is not only a string of characters on paper. It is an assertion about the physical universe that can be checked using EXPERIMENTS, there is no analouge of this in mathematics. There is nothing to check against, just symbols on paper. However, I like mathematics not for manipulating symbols, but for its beauty (That is something that would take a lot to talk about). Sorry for the many comments Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH I probably bothered you with a lot of comments, but I think what I will write now is worth reading. Even if physics becomes axiomatized, I still think it is different from mathematics in the following sense: You prove a theorem from a certain theory $T$, it does not matter if the universe satisfies theory $T$ or not, we are proving theorem s for worlds satisfying theroy $T$ only, it doesn't even matter if no such world exists. mathematics could be viewed as plain manipulation of symbols, physics is not just manipulation of symbols about. Dec 19 comment Is physics rigorous in the mathematical sense? Hi. I don't mind taking the gravity equation as an axiom. What I want to ask (perhaps different from what the OP would like to ask) is: Suppose we assume certain axioms to describe the universe and use them to derive a statement P. Is the derivation of P from the axioms rigorous ? This is like the question: Is physics axiomatic ? Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH In group theory for example, I view the theorem that identities are unique as: The set of statements of group theory proves formally the statement: identities are unique. Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH Secondly, I don't like to think of mathematics as if it asserts the theorems. I like to think of it as asserting the implication. For example, mathematics does not show us that the fundamental theorem of calculus is true, but rather that the of axioms of ZFC PROVE the fundamental theorem of calculus. Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH Thus, the axioms were not just chosen to maximize theorem-proving power. I believe the axioms were chosen to describe our own intuition about sets. In my opinion, there are philosophical reasons why sets were chosen the way they are Dec 19 comment Is physics rigorous in the mathematical sense? @DavidH I disagree about "The common axiom sets found in formal mathematics were chosen to maximize theorem-proving power/efficiency, not because they are somehow "self-evident" truths". Firstly, if theorem power proving were given higher priority than being "self-evident truths" then the set of statements $\{\forall x [x\in x],\lnot\forall x[x\in x]\}$ could have been used as axioms for math instead of ZFC. It certainly has a higher theorem proving power since it can prove any statement as it is inconsistent.
