Here is a reference sheet (PDF, 95 KB)(handed out in class with key terms from PHY117, and german/english translation)
Texts:
Formelsammlung Mittelschulphysik (PDF, 396 KB) is also useful for usage of basic formulas.
Exercises are posted on OLAT every 2 weeks on Friday after lecture.
Exercise sessions in the following week will help you understand the terms and concepts of the exercises. Exercise sessions in the second week after the exercises are assigned will explain the solutions. It is expected that you will complete the exercises before this second exercise session.

Online exercise class
The places available for permanent participation in the online class are full. Permanent assignment to the online group is no longer possible, except for verifiable medical reasons. In this case, please apply by email.
One-time change:
If you are ill or cannot attend your regular class for another important reason, you can switch to the online class for a single session, please send an email with the following information: reason, date of the online class, your name, your regular class.
There will be no podcasts of exercise classes.
Exam guidelines :
Exams will be similar in style to the exercises. A formula sheet with all needed equations will be provided to you in the exams. The formula sheet will be sent to you by the end of the semester to help you study. We will provide you with paper and a calculator if needed. The final exam will be printed in english and in german. The following are forbidden in exams :
Your grade is based on the following assessments :
Attendance is expected and recorded for exercise sessions. The final examination will be composed of questions similar to those presented in the lectures and the weekly exercises.
The course will cover modern physics topics such as relativity, quantum physics, atomic, nuclear, and particle physics, radiation, particle-wave duality, particles interacting in matter, particle detection. These ideas will be used to explain the basics of modern radiation techniques for diagnostics and treatment, and such instruments as X-rays, CT scanners, PET scanners, NMR, MRI, etc.
| Lecture schedule (12 lectures) | Topics | PDF of chalkboard | Additional resources |
|---|---|---|---|

Week 1 (Feb. 25, 2022) |
Units, particles, Feynman diagram |
Units and basics on vectors are in Prof. K's first semester script (PDF, 5 MB). Feynman diagrams are typically in quite difficult quantum field theory textbooks, so stay away from those. You don't need to know the details behind the calculations. If you have questions, just ask Prof. K or your TA. | |
|
Week 2 (Mar.4, 2022) |
Electromagnetic radiation is made of photons. | Notes Lecture 2 (PDF, 6 MB) | See Prof. K's second semester intro physics script (PDF, 3 MB) for energy transfer of electromagnetic radiation (Wien's law, Planck radiation, etc.). Also, see any intro physics text book. For the energy and momentum of a photon, see an intro physics textbook with a section on "modern physics". |
| Week 3 (Mar. 11, 2022) | But are photons particles or waves ? |
Any intro physics text book with a modern physics section. For example, Tipler, Part 6 on modern physics. Are you confused about wave-particle duality ? Try googling "wave-particle duality", and "double-slit experiment". There are lots of cool websites and youtube videos on this. |
