Just a minute.  Using the words theory and fundamental science
principles interchangeably is flawed.  There is a big definition
difference between these two.  Theory can be defined as an assumption or
guess which is clearly different from fundamental science principles.

The train doesn't stop here anymore.

One of my favorite EE profs liked to use the words "zero length" to 
emphasize the potential significance of stray inductance, stray 
capacitance, and stray resistance in any given circuit. SIMPLE circuits 
assume ideal components, with those ZERO length leads. Real circuits
have 
those strays (some folks call them parasitics). 

Some ignorant people like to talk about the difference between theory
and 
reality, as if there is something wrong with the science. In fact, there
is 
NO difference between fundamental science principles and reality --
those 
ignorant folks are simply ignoring important parts of the problem, like 
stray C, stray L, and stray R. Hence, my own personal way of saying it
-- 
"if you think there's a difference between theory and reality, you don't

know enough about one or the other."
