So, I have a basic mathematical knowledge but I have been dealing with complex data structures and formulas part of my computer science skills.
Today morning, in the "Paris Nord" one of biggest Paris subways stations, this formula caught my attention (in the link). My intuition says, = must be left handed and right handed by another expression; which is not the case.
Mathisfun.com says
Parentheses or "round brackets" are the familiar ( ) symbols used in pairs to group things together.
and my data structure knowledge says: Parenthesis can be used to specify a not scalar type, like tuples; In the same way as brackets define a different structure.
knowing this, I can grasp the notion of defining a structure, on a value. But I know this is not the case here; so What I am missing.
it most likely means $$r(T,h)=\frac{0.622he_8(T)}{p-he_8(T)}$$ and $$r(T,h)<r_{min}$$
