Physics

This is a non-calculus introduction to physics in a biological context, introducing the physical principles that underlie the biological world. It covers the major topic areas of forces and motion, bulk materials ( elasticity and fluids), thermodynamics, electricity and biomedical imaging. The course will be divided into four modules: Forces and motion; Energy and waves; Bulk material properties; Principles of sensing.

This course addresses a number of important mathematical methods often used in physics. The course discusses topics including basic complex analysis, differential equations, Fourier series, and transforms, tensor calculus, variational calculus, orthogonal functions, and Laplace transformations.

This course covers the process of mapping a scientific problem onto a computer algorithm to enable it to be modeled, along with an introduction to visualization techniques (e.g., via either gnuplot, Matplotlib, or similar), to help visualize the solution. Example problems are drawn from the Junior Honors physics program, with additional examples from everyday problems. The course consists of lectures on the algorithms and weekly hands-on practical sessions, with three checkpoints. Topics include theoretical background of core simulation techniques (including Monte-Carlo integration and Monte-Carlo simulations, cellular automata, and molecular dynamics simulations or partial differential equations); implementation of these core techniques in Python to solve specific (and potentially unseen) physics problems; integration of visualization (evolving fields, moving particles, live graphs, etc.) and graphical user interfaces into simulation codes; the notion and origin of errors and instabilities in numerical algorithms, and simple techniques for handling them; and key issues that arise in the development of scientific software, such as compromises between efficiency and flexibility, the incorporation of third-party library code (and its distinction from plagiarism), and the utility of good-quality documentation and coding style.
