Syllabus Description:

Welcome

We live in a technological world surrounded by machines of nearly magical ability. For your grandparents knowing where you were to within a mile or two required specialized equipment and training—now you just take out your phone. And if they were injured doctors used radioactive minerals and silver salts to look inside the body instead of an MRI machine. But how do GPS and MRI machines work?

It turns out that relativity and quantum mechanics have become the foundation of much of modern technological life. In this class we will explore how our modern technological world depends on relativity and quantum mechanics, and along the way we will explore the history of quantitative knowledge—how we know what we know.

Embarking on a modern physics class can be intimidating—few things trigger more fear than “a simple introduction to physics.” But to the intrepid and brave, I will make a few promises before we start:

  • No math. While the language of relativity and quantum mechanics is written using fairly advanced math, I don’t believe one has to read Japanese before you can appreciate Japanese art. Our journey will focus on the beauty and elegance of the physical world.

  • No philosophy. There has been a fascination with the ‘meaning’ of quantum mechanics and relativity, but we’ll leave that discussion for pints down at the pub. Here we will focus on what we see.

  • Everything we encounter will be experimentally verified. While some of the results might be surprising, nothing we encounter will be speculative. This is how our world works.

Grading

Grades will based on homework, quizzes, midterms (Feb 4 & Mar 3), class participation, and a final paper. There will be no final. As this is a new class, the exact division of points is TBD. In general the early part of each week will concentrate on understanding how the physical world works, with the end of the week looking at how that impacts our lives and the history of quantitative understanding. Homework will be due Saturday night each week, and extra credit on homework will always be available for creativity or extra effort. Reading load will be modest, but much of the reading will be difficult (must be read slowly). Quizzes will be assigned along with the reading assignments.

Accommodations

Most accommodation requests will be handled through Disability Resources for Students, including special testing requests on the midterms. 

Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW’s policy, including more information about how to request an accommodation, is available at Religious Accommodations Policy (https://registrar.washington.edu/staffandfaculty/religious-accommodations-policy/). Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form (https://registrar.washington.edu/students/religious-accommodations-request/).

Catalog Description: 
Physics for students in the arts, humanities and social sciences. Students get a flavor of what physics is about, including scientific procedures. We will focus on the theory of Relativity. This revolutionized physics in 1905 and led to amazing predictions, like the existence of black holes and the production of gravitational waves, confirmed in 2016. Only math at high school level is required. Offered: WSp.
GE Requirements: 
Natural World (NW)
Quantitative and Symbolic Reasoning (QSR)
