ABSTRACT

This chapter explains how to investigate the quantitative aspects of scientific problems. Throughout history people have tried to supply explanations for what they observed. There is probably less agreement on what constitutes science. Many people, including a depressingly large number of scientists, believe it is the search for universal immutable laws of nature, that is, a hunt for truth about the physical world around. It's just the use of scientific knowledge to design and construct tools and machinery to carry out specific tasks. For instance is the use of scientific knowledge about the strength properties of various materials to construct buildings and bridges; use of knowledge of the behavior of fluids and of various types of motors to construct airplanes. Beginning of the twentieth century deterministic models for scientific or engineering questions were usually adequate. That is, discrepancies between the models' answers and the actual measured results were usually inconsequential.
