## PHYSICS 94SI: Diverse Perspectives in Physics

Have you ever wondered how your professors got to be where they are today? Or what it is like to be a female professor, a faculty member raised first-generation/low income, or even a Nobel laureate? Professors of a diverse set of identities and backgrounds will share the story of their lives and career trajectories over lunch, with an emphasis on their personal lives and experiences as undergraduates and graduate students. A Q&A session will follow. Free lunch provided.

## PHYSICS 96N: Harmony and the Universe

Harmony is a multifaceted concept that has profoundly connects music, mathematics, physics, philosophy, physiology, and psychology. We will explore the evolution of our understanding of harmony and its immediate application in the function of musical instruments, and employ it as a nexus to understand its role in revolutionary scientific advances in gravity, relativity, quantum mechanics, and cosmology. In these explorations, we will examine some of the fundamental mathematical tools which provide us our current understanding of harmony. We will also see how the some concepts surrounding harmony are in tension, if not conflict, and how some great thinkers have followed them down down blind alleys and dead ends. The aim of the course is to show the enormous consequences of harmony in the evolution of our understanding of the universe, and how science itself progresses in fits, starts, and setbacks as old ideas intermingle with new developments. We will also see how objective/quantitative aspects of harmony interact with subjective/qualitative considerations, and how cultural perspectives and prejudices can affect the progression of science.

## PHYSICS 100: Introduction to Observational Astrophysics

Designed for undergraduate physics majors but open to all students with a calculus-based physics background and some laboratory and coding experience. Students make and analyze observations using the telescopes at the Stanford Student Observatory. Topics covered include navigating the night sky, the physics of stars and galaxies, telescope instrumentation and operation, imaging and spectroscopic techniques, quantitative error analysis, and effective scientific communication. The course concludes with an independent project where student teams propose and execute an observational astronomy project of their choosing, using techniques learned in class to gather and analyze their data, and presenting their findings in the forms of professional-style oral presentations and research papers. Enrollment by permission. To get a permission number please complete form:

## PHYSICS 108: Advanced Physics Laboratory: Project

Have you ever gotten to come up with a scientific question you'd like to explore, then worked with a small group to plan, design, build, and carry out an experiment to pursue this? Most projects pursued (drawn from condensed matter or particle physics) have never before been done in the class. This is an accelerated, guided "simulation" of real frontier experimental research. We provide substantial resources to help your team. Prerequisites
PHYSICS 105,
PHYSICS 107.
PHYSICS 130 preferred.

## PHYSICS 113: Computational Physics

Numerical methods for solving problems in mechanics, astrophysics, electromagnetism, quantum mechanics, and statistical mechanics. Methods include numerical integration; solutions of ordinary and partial differential equations; solutions of the diffusion equation, Laplace's equation and Poisson's equation with various methods; statistical methods including Monte Carlo techniques; matrix methods and eigenvalue problems. Short introduction to Python, which is used for class examples and active learning notebooks; independent class projects make up more than half of the grade and may be programmed in any language such as C, Python or Matlab. No Prerequisites but some previous programming experience is advisable.
