I was talking to a Fi-user who mentioned she tried to feel abstract concepts when she studied physics, math, and other subjects replete with abstractions. So, for example, in Newton's 2nd Law, which can be stated as
where m is mass
a is acceleration
v is velocity
p=mv is momentum, and
d/dt is the derivative wrt time
she said she tried to feel momentum. How do you go about understanding abstract concepts? Do you use your primary cognitive functions, like my friend does, and try to feel, sense, or intuit the concepts? What is that process like?
