English mathematician, astronomer, and physicist Sir Isaac Newton.
Science is the search for truth, and the method is the progressive elimination of possible answers to questions by proving them false. The underlying assumption of all science is that all effects have a cause. The force of gravity, for instance, is the cause of objects falling toward the center of the earth. A related proposition from observed reality is that feathers and steel balls fall at different rates, which seems to indicate that gravitational force is different for different objects. The way to test the proposition is to remove as many confounding factors as possible, such as air resistance on the surface of the objects. Thus, when the same two objects are observed in a space where air has been eliminated, we isolate the effect of gravity to a much higher extent and observe that the feather and the steel ball accelerate at precisely the same rate every time.
The problem for science is that the world is incredibly complex, with so many different causes constantly interacting that it is extremely difficult or impossible in many cases to eliminate the confounding factors or even identify all causes and effects. That is especially true …read more
