Number of basic physical quantities

  1. Apr 14, 2005 #1
    Recently, I was thinking about this:

    Am I right if I say that there are only 4 (and exactly 4) basic physical quantities which are enough to explain all observed phenomena in nature?
    (of course I mean HOW, not why)
    (for example length, time, mass and electric charge or current)


    (Because the SI table for example would explain how natural phenomana work and there are 7 basic quantities in it, but luminous intensity is just human subjective perception of light energies, mole is just a natural number and temperature is just something artificial talking about velocity of particles.)


    thanks
