I like a passage in a book by the (very) mathematical physicist Robert Georch: "It seems to me that "theories of physics" have, in the... -
hutchphd reacted to Dale's post in the thread I Can Axioms Revolutionize Our Understanding of Physics? with Like.
There are lots of papers on various axiomatizations of physics. You may want to start with some research on what has already been done...

You have first to decide what correct means. It may refer to a definition, in which case it is correct in the sense of an abbreviation...

hutchphd reacted to A.T.'s post in the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form? with Like.
The OP's error was correctly pointed out in post #7: A vector magnitude, which is always positive, was replaced by a signed vector...

hutchphd replied to the thread B Why Does Hooke's Law Use a Negative Sign in Scalar Form?.Hookes Law is a vector equation. In one dimension it is a 1D vector equation, not a scalar equation. Also in 1D Newton's Law is a 1D...

hutchphd reacted to PeroK's post in the thread B If the Universe has a cause, what caused that cause? with Like.
