Approaches: to equations and doing science

Here is a post (via John Baez’s Google+ share) that describes the three approaches to equations: what the post calls theoretical and formula based can also be called as  analysis and seeking analytical solution respectively. There are, in a similar manner, three approaches to doing science itself: theoretical, experimental and computational. The best approach, be it equations or science, is, of course, to combine all the three (in proportions according to taste).
