Science and Humanities, huh?
Well, if I were to take a stab in the dark, I would say that Humanities helps Science decide where to investigate by giving us a priority list based on philosophy, sociology, etc.
Conversely, Humanities also takes what Science discovers and gives that meaning as well. Finding that hypothesis A is a valid hypothesis and its predictions are shown to be accurate means nothing if we don't then understand the ramifications to us as a society. Knowing that asteroids and comets have hit the Earth and wiped out much of the life that was here at the time means nothing if we don't recognize that a comet or asteroid in the future is a threat to us, and so we take steps to minimize that threat.
