Scientific method is the way scientists learn and study the world around them. It is the process by which scientists work over a period of time to construct an accurate (i.e. reliable, consistent and non-arbitrary) representation of the world. In the study of natural phenomenon, personal and cultural beliefs strongly influence our interpretations and perceptions. Scientific method relies on standard procedures to minimize these influences when developing a theory. Scientific method consists of four steps: (1)- Making an observation of a phenomenon. (2)- Formulating a hypotheses to explain the phenomenon. (3)- Proving the hypotheses correct by a series of experiments and tests. If the experiments do not bear out the hypotheses,…show more content…
Almost 2000 years later Galileo challenged Aristotle’s s work on mechanics and cosmology. Galileo did not ridicule Aristotle, but simply showed that he had jumped to the wrong conclusions and derived at inadequate answers because of his physics being not very mathematical. Errors in Aristotle’s work were rectified through direct observation and by the availability of new instruments and experimentation techniques in the 17th century. Amongst other contributions, Galileo contradicted Aristotle’s view that bodies naturally returned to their natural place. It is believed that Galileo demonstrated by throwing different weights from the Leaning Tower of Pisa that the weight of the bodies was irrelevant to their speed of falling and only the density of the medium counted. Lavoisier interpreted facts discovered by others and corrected them for errors. He is considered the father of chemistry although he discovered no new chemical substances apart from a few new chemical facts. Lavoiser used to carry out a lot of experiments, quantify their results and take various precautionary measures. He studied Stahl`s theory on combustion and found errors in reasoning. Stahl had given the concept ‘phlogiston’ for combustion but Lavoiser proved that no such thing existed. Lavoisier repeated Boyle`s experiments which had showed an increase in the weight of cal of tin when
