It's important to focus on the Fundamental Dimensions used in physics, so we can understand at any given point of any given physics discussion what we are talking about. Infact, if you add 2 apples to 2 apples you get 4 apples. But if you add 2 apples to 3 oranges... what do you get? Yes, you get 5 fruits, but you will loose the particular aspect of the apple and of the orange that you started with. So let's focus on the fact that usually we deal with 4 fundamental dimensions or units in: # Length measure # Time measure # Mass measure # Electric? charge measure ... and that we CAN NOT obviously add a Time measurement (say 5 seconds) to a Length measurement (say 1 mile) because it makes ABSOLUTELY NO sense. (1 sec + 1 mile = ???) From these 4 dimensions we can talk about the 80% of ALL physics problems existing now or in the future... (Future?? Who knows the future??) If you want to talk of the other 20% you need to add other 3 dimensions # Thermodynamic temperature measure # Amount of substance measure # Luminous intensity measure Once we agreed on so... How would you measure ESP ([Extra Sensorial Perceptions]?)? (LOL) :) (So we can talk about 101 % of physics now, say metaphysics) |
