Why is a rounded nose on an airplane/rocket more aerodynamic than a pointed nose?

I remember asking my high school physics teacher this and he didn't know the answer.  Here's hoping some kind redditor out there can answer my question 15 years later.

If it's not aimed directly towards the air flow, a pointed nose can produce flow-detachment, turbulence and drag.  A rounded nose is more immune to this effect.  Specifically, the front stagnation point in the flow diagram needs to land on a flat surface.  As the fuselage changes relative angle to the oncoming wind, the stagnation point can just move along but without any large outbreak of turbulence.  The same explanation applies to the round leading edge of wings vs. the sharp trailing edge.

Designs for supersonic flight are very different, so the above doesn't apply very much to rockets and fighter planes.
