PHYSICS AS AN OBJECTIVE METHOD
1. It has long been known that when experiments are to be per-formed, one cannot
rely too much upon the human senses of touch, sight, hearing, etc., to make accurate
observations. Methods of measurement that rely upon the senses entirely are called
subjective methods. Methods that make use of scientific instruments are generally
called objective methods.
2.In the early history of science, laws were frequently discovered by the use of
subjective methods. Progress was slow, however, until such methods were replaced by
objective methods using measuring instruments devised to give greater and greater
precision.
3. It is true that many scientific discoveries have been made in the past with what we
now would call the crudest of apparatus and equipment. It is the development of
precision instruments and apparatus, however, that has led, particularly within the last
several decades, to discoveries that are far-reaching in their theoretical implications
and are of extreme practical importance to the advancement of civilization.
