Albert Einstein once said, "The whole of science is nothing more than a refinement of everyday thinking." The first thing scientists must do is to ask a question or identify a problem to be investigated. 46) Then scientists working on this problem collect scientific data, or facts, by making observations and taking measurements, which must be verified or confirmed by repeated observations and measurements, ideally by several different investigators. 47) The primary goal of science is not facts in and of themselves, but a new idea, principle, or model that connects and explains certain facts and leads to useful predictions about what should happen in nature. Scientists working on a particular problem try to come up with a variety of possible explanations or scientific hypotheses of what they (or other scientists)observe in nature. Then experiments are conducted (and repeated to be sure they are reproducible)to test the deductions or predictions for each hypothesis so as to arrive at the most plausible or useful hypothesis. 48) If many experiments by different scientists support a particular hypothesis, it becomes a scientific theory―a well-tested and widely accepted idea, principle, or model that usually ties together and explains many facts that previously appeared to be unrelated. Converting a scientific hypothesis to a scientific theory is a difficult process, often requiring decades, even hundreds of years. To scientists, theories are not to be taken lightly ,for they are ideas or principles stated with a high degree of certainty because they are supported by a great deal of evidence. Another end result of science is a scientific law ―a description of what we find happening in nature over and over in the same way, without known exception. The more complex the parts of nature scientists study, the more difficult it becomes to discover scientific laws. 49) There are many scientific laws of physics and chemistry, only a few in biology, and even fewer (and less reliable ones) in fields involving complex interactions of multiple factors ( variables), such as ecology, climatology( study of climate) ,and social sciences such as economics and politics. The scientific process requires not only logical reasoning, but also imagination, creativity, and intuition. According to physicist Albert Einstein," There is no completely logical way to a new scientific idea. "50) Intuition, imagination, and creativity are as important in science as they are in poetry, art, music, and other great adventures of the human spirit that awaken us to the wonder, mystery, and beauty of life, the Earth and the universe.
