The Light and Heat Pre-Collegiate course, offered by Stanford University, aims to provide an introduction to the fundamental principles of optics and thermodynamics. The course content, which was originally developed by Professor Mason Yearian, covers a broad range of topics, such as temperature, properties of matter, the kinetic theory of matter, light and electromagnetic waves, reflection and refraction of light, lens systems, interference, and diffraction. The thermodynamics portion of the course draws primarily from Professor Douglass Osheroff’s course, while the optics portion has been revamped to include a more rigorous exploration of electromagnetic waves, polarization, and interference. The course is delivered online and allows high school students to work through the material at their own pace, with the support of expert instructors. As of now, there are no lab components to this course. The course was created to be comparable to Stanford's traditional in-person courses, meaning students can expect a similar level of academic rigor and depth. To participate in the Light and Heat Pre-Collegiate course, students must have completed the AP Physics C: Electricity and Magnetism, and AP Calculus AB, BC, or equivalent. The required textbook for this course is either "Physics; For Scientists and Engineers" by P. Tipler (5th or 6th edition) or "Fundamentals of Physics" by Halliday and Resnick (7th edition or later). Upon completing this course, students can expect to gain a deep understanding of the fundamental principles of optics and thermodynamics. They will not only gain knowledge about these topics but also develop their ability to understand and apply these principles to real-world situations. This course is particularly beneficial for students who are interested in pursuing further studies or careers in physics or related fields.
