Please feel free to unmute and call out questions. If you are just listening please leave your audio muted to avoid unintentional and embarrassing background noises. Whether you turn on video or not is up to you, but it is easier to understand you if your video is on.
Do you need still need to attend class (virtually)? Yes, it is part of your class participation grade.
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 (someday). 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.
Grades will based on homework, quizzes, midterms (Feb 1 & Mar 1), class participation, and a final paper (due March 13). There will be no final. 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.
When we are in person:
- You are required to wear a well-fitting mask at all times.
- If you are symptomatic with COVID, flu, or another illness, please do not attend in person. Video recordings of all lectures will be linked below on the syllabus.
- It is highly recommended you join the Husky Coronavirus Testing program and sign up for WANotify if you have not done so already. If you test positive for COVID or are in close contact with someone who does, notify email@example.com. Please get a Vaccine Booster (3rd shot) as soon as you are eligible.
When class is remote
- Please be understanding of connectivity issues - should the speaker's internet go out during class, please stand by for 10 minutes before logging out.
- You may not share video or audio of this class.

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/).
The syllabus page shows a table-oriented view of the course schedule, and the basics of course grading. You can add any other comments, notes, or thoughts you have about the course structure, course policies or anything else.
