OBJECTIVES OF PHYSICS PRACTICAL

  1. To provide an experimental foundation for the theoretical concepts, introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.
  2. To familiarize students with experimental apparatus, the scientific method and methods of data analysis, so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.

To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic errors. This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.
