The scientific method may at one time have been conceived by philosophers, but we are centuries away from that time, and in recent centuries, all the refinements and improvements to science have been done by scientists. The roots of the scientific method which one could reasonably call philosophy are so changed as to be considered invalid today.

The reverse is not true--scientists have written a lot of philosophy--and since they tend to base their philosophy in reality rather than logic based on speculation, it tends to be better philosophy than philosophers.
