comment Why can you add moment vectors?
For moment vector, its sense of "direction" is whether it is clockwise or anticlockwise.

comment Why can you add moment vectors?
You cannot tell if it is a function. It has to be a number.

comment Integrating factor $1/T$ in 2nd Law of Thermodynamics
I'd love to see if there is a proof without referring to ideal gas too.

comment Integrating factor $1/T$ in 2nd Law of Thermodynamics
Perhaps it can be expressed in more general form, but I never heard that something dS=dQ/T can be proven in total without referring to first law. Yes, entropy may be alternatively defined in terms of microstates, but that would be off topic.
