General What is your general opinion of the course? 4 50% 2 5 50% 2 Mean 4.5 Comment 1 of 19 11/24/2011 01:42 PM
3 have commented on this question Grade = 4 (one comment) The course is a really good addition to the experimental course I had in particle physics, where nobody was taking about Lagrangians or how to estimate cross-sections. Grade = 5 (2 comments) very interesting, i've learned a lot It was a good introduction to the standard model and how to perform approximative calculations using the theory. We got an overall picture, without loosing ourselves into too much details. B. Literature What is your general opinion of the "Modern Elementary Particle Physics" book by Gordon Kane? 4 100% 4 Mean 4 Comment 3 have commented on this question Grade = 4 (3 comments) The book has a logical structure and is very well written, but the experimental information is a bit out-of-date. I had the old edition so it is a bit out of date and with lots of mistakes but I like it. The level was good, but it was sometimes a bit messy (mainly the order of the different parts). C. Lectures What is your general oppinion of lectures with Leif Lönnblad? 2 of 19 11/24/2011 01:42 PM
4 75% 3 Mean 4.2 Comment 3 have commented on this question Grade = 4 (2 comments) sometimes the black board writing could be more structured but anyway he explained things quite well. sometimes the handwriting on the blackboard is difficult to read Grade = 5 (one comment) Not going to fast, makes sure that the students understand, allways ready to answer questions. I appreciate the lecture notes on the web page. What is your general opinion of the lectures with Johan Bijnens? 5 75% 3 Mean 4.8 Comment 2 have commented on this question Grade = 5 (2 comments) very well structured The same things as for Leif. Very good notes during the lecture. D. Problem sessions 3 of 19 11/24/2011 01:42 PM
What is your general opinion of the problem sessions? 5 50% 2 Mean 4.2 Comment 2 have commented on this question Grade = 4 (one comment) ok, same level as the exam Grade = 5 (one comment) When doing problems and presenting the solution you can really see how much you know and how well you have understood the theory. The number of problems every week was just enough. F. Written exam What is your general opinion of the written exam? 4 50% 2 Mean 4 Comment 3 have commented on this question Grade = 4 (2 comments) level is ok The level was OK. It would have been nice to discuss the problems (or get solutions). Grade = 5 (one comment) 4 of 19 11/24/2011 01:42 PM
This was the first time I really understood how to estimate the p 's or \bar e\gamma e's in the cross-section formula. It is fairly easy but from the lecture it was not clear to me. Maybe it had been useful if this were written to the blackboard instead of only telling it. The exam had both easier and not so easy questions so I think it was ok. Part 2. Intended Lerning Outcomes. In this section you should go through all the different parts of the course and think about how well you have you have accomplished the learning goals. 1 = You have not at all acquired the knowledge intended 3 = You have adequately acquired the knowledge intended 5 = You have acquired much more knowledge than intended A. The building blocks of the standard model The student knows about all the quarks, leptons and gauge bosons in the standard model. 4 50% 2 Mean 3.5 The student knows about the most common hadrons. 5 of 19 11/24/2011 01:42 PM
4 50% 2 Mean 3.5 The student is able to describe the ordering in mass between the different particles. 3 75% 3 Mean 3.2 One has answered this question I am not really sure what is meant by "knowledge that's intended". My interpretation is what I thought I would learn in this course. B. Group theory The student understand the basics of group theory and understands how groups can be used to describe symmetries. 2 25% 1 Mean 3 6 of 19 11/24/2011 01:42 PM
2 have answered this question the basics should be extended, include for example how you should interpret the "x" sign in SU(2)xU(1). some parts of the group theory were not needed later in the course which made them a bit unneccessary. C.
