Document Summary
What is physics: physics is the study of all nature at its most fundamental levels. Important to note that not all observations are precise. In fact, many times observations are imprecise and unclear (this is especially the case with cutting edge research: has huge applied and technical aspects. Experiment and theory: experiment: yields observations, natural patterns and data, theory: intellectual framework that seeks to rationally explain the results of experiments (observations, etc. , parameters: Must have a predicted value: skill: know how to identify theories. If a theory has been tested many times and appears to be correct, it will then become a law: remember, laws can still be disproven (newton"s law) Scale: we need a good system of units to make practical physical measurements that can accommodate a large range of sizes (from extremely tiny to significantly massive, the systems of units should be unchanging and universal.
