Preamble |
---|

The principle of science is the following: the test of all knowledge is experiment. Experiment is the sole judge of scientific truth. - R. P. Feynman
Introduction: This is a two-semester long laboratory course in physics for the first year BS-MS students. The course aims to develop general experimental skills such as taking and recording data accurately, analyzing and presenting data through use of tables, chart and graphs, etc. Concepts of error analysis, precision and accuracy of data, significant digit etc. will be taught. Students are expected to enjoy doing things by their own hands. They will perform simple but interesting experiments to verify various concepts of physics that they have learnt in the classroom lectures. Successful students are expected to develop critical thinking skills such as being able to make reasonable predictions and hypotheses from known facts, being able to see the relationship between experiments and equations and seeing how they apply to the real world. This laboratory course is designed to be beneficial to all students irrespective of whether they choose to major in physics or not. |
