Course information sheet

References & texts

References for each lecture will be added below. 

A document with german/english translations of common physics quantities, as well as a reminder of the units of such quantities is available here PHY127-FS2024-helper.pdf (PDF, 95 KB) 

The formula sheet for completing exercises and for the final exam:

The following can serve as a reference for the basic physics (from PHY 117) 

Texts: 

  • Paul A. Tipler, Gene Mosca: Physics for scientists and engineers.  
  • Halliday & Resnick : Fundamentals of Physics. 

Additional resources to help with mathematics. 

  • MHP: Mathematische Hilfsmittel (PDF, 587 KB) (in german) derivatives, integrals, series expansions, statistics, vector algebra, coordinate transformations, tensors, ... )
  • C.B. Lang und N. Pucker: Mathematische Methoden der Physik, Spektrum Verlag, Heidelberg und Berlin.

Formelsammlung Mittelschulphysik (PDF, 396 KB) is also useful for usage of basic formulas.


Exercises

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 schedule

Exam guidelines  :
Exams will be similar in style to the exercises. A formula sheet with all needed equations will be provided to you for use throughout the semester, and in the exams.  We will provide you with paper and a calculator.  The final exam will be printed in english and in german.   The following are forbidden in exams : 

  • Any means of communication (mobile phones, smart watches, etc.)
  • Any kind of calculator, laptop, or electronic storage device
  • Any additional formula sheets or written notes. 

Exam date: 28.06.2024, 10:00 - 12:00

Repeat exam date: 13.09.2024, 14:00 - 16:00


Grades

Your grade is based on the following assessments : 

  • 100%  final examination

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. 


Outline of course

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. 

In order to gain some  insight into the prerequisites students bring with them to this lecture, I ask you to complete this  survey in OLAT during or shortly after the first lecture.
