Looking at my bookshelf I see books titled ‘Electromagnetic Theory’, ‘Theoretical Mechanics’, ‘Control Theory’, ‘Optimization Theory’, ‘Automata Theory’, ‘Theory of Semiconductor Devices’, ‘Chaos Theory’ etc. to name a few.
Using your understanding of the definition of theory vs fact. Given that you are using a computer and the Internet are they fact or theory or something else?
Looking at your bookshelf.....Being in a garage does not make you a car, owning science books doesn’t make you a scientist.
