| Lecturer : | Prof. Ben Kilminster |
| Lectures ( PHY127.1 ): |
Friday, 08:00 - 09:45 |
| Exercise sessions ( PHY127.2 ): | Tuesday or Wednesday, 13:00 - 15:45 (First : 28th Feb 2023) |

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.
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 :
Exam date: 30.06.2023, 14:00 - 16:00
Exam review: 12.07.2023 (primarily for those who have not passed)
Repeat exam date: 15.09.2023, 14:00 - 16:00
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.
