A List of Essay Topics
Small Intro and Essay Topics


Exercises are kept on Monday at 10 - 12 o'clock in TÄ219. First exercise is on 25.3.2013. Students are encouraged to work through the exercises before and during the excercise session. In order to gain points the exercises must be given to the assistants before Wednesdays at 14.00 (before each lecture). The worked out exercise-papers (with your name and email!) can also be left to a denoted box at the hall of the theoretical physics for gaining points. New exercises and the solutions of the previous will appear every Wednesday to this wiki page. For questions, comments or feedback about the exercises you may also contact the assistants.

Exercise 1

Exercise 2

Important note: in Exercise 2 Task 2 part b),  *lambda is given wrong. It should be 37 g/cm2 * ln(2).

Aftermath: A summary of the questions, answers and discussions of exercise session on Monday 15.4 (updated a bit). Thanks to all who came to the session!

Exercise 3 

Important note: in Exercise 3 Task 2 part a),  the formula given yields centimetres as a result if values plugged in to the formula are given in the spesified units.
Important note: in Exercise 3 Task 2 part a), "B is paraller" should be "the magnetic field is parallel".

Aftermath: A summary of exercise session on Monday 22.4. Thanks for all the questions!

Exercise 4
Hints for task 1: (link) Thanks to the student who wanted to share the hint with all!

Important note: in Exercise 4 Task 1, when doing the integration over the full solid angle: do the integration over the half-spheres separately and use reason with "+/-" signs! "T" (time) is lacking from the last formula of the assigment 1D).
Important note: in Exercise 4 Task 3, the cross section given is the total cross section.
Important note: in Exercise 4 Task 3, we calculated the result over an exposure time of one month. In reality, the exposure times used in the experiment varied, being most typically 2-3 months.

Aftermath: A summary of exercise session on Monday 6.5. Thanks for participating.
