Principles of Physics and Introduction to Nanophysics

Aim

The course gives an introduction to physical theory and experiment. The theoretical part repeatedly demonstrates that wide areas of physics can be understood trough a clear understanding of a few basic concepts and principles. One purpose is to increase the interest for physics and to demonstrate the need for mathematical tools. The same simple principles are also used to understand and explain properties of molecules and materials. Furthermore, an orientation about the research conducted at the department is given.The experimental part stresses what is essential to make good physics; imagination to suggest possible hypothesis, experimental technique to test, ability to find a language (concepts) that gives a simple description. Strong emphasis is on the students ability to present their results in writing and to critically judge the validity of their own work.

Content

The experimental work includes experimental problem solution where basic mechanical systems are studied. An important goal is the ability to account for results in writing and to critically assess the validity of own work. The theory part includes both classical and modern physics. Within classical physics, mechanics, thermodynamics and statistical physics is treated. The thermodynamics pat is based on concepts such as micro- and macrostates. These fields are used to explain properties of materials and molecules. The modern physics topics are: A historical perspective on quantum physics, a philosophical perspective on quantum physics, Planck's description of the black body radiation and its connection to the green house effect, simple solutions to the Schrödinger equation illustrating energy quantisation, tunnelling, quantum mechanical operators, Bose-Einstein statistics illustrating the black body radiation. The explanatory power of modern physics is demonstrated and related to modern research
