Document Summary

Part 1: we (cid:498)know" things from personal experience; conventions (cid:523)i. e. alphabets, knowledge. )t comes from latin (cid:498)knowledge. (cid:499) science means developing testable explanations and predictions about the material universe. It is a body of knowledge that can be rationally explained and reliably applied: fundamental assumptions of science are that: there is an objective reality. Idea is to build a framework to organize collected numbers, colors); different beliefs; and the scientific method. What is science? shared by all rational observers; this objective reality is governed by natural laws; these laws can be discovered by means of systematic observation and experimentation (this limits the number of things you can explore) How do we conduct science: the scientific method! You ask a question, formulate a hypothesis, make a prediction, conduct an experiment and analyze the results: after the above steps are completed, peer review comes into play. After this confirmation process, you have to start testing additional hypothesis.
