Lecture notes on various topics are available here. Some of them may be incomplete. In case you use them and find a mistake please point it out to me.

This is an undergraduate course, primarily aimed at second year students. The course now has its own dedicated webpage.

This is a graduate course. It is going to be offered to the masters students of astronomy and physics in Stockholm Univeristy next year (2016) in the spring. The course now has its own dedicated webpage.

I taught this course as a part of the program Stockholm University offers to students who are training as science teachers in gymnasiums (For the ignorant, a gymnasium in this sense is not a gym. ). I taught all the course except circuit theory. Which were covered by my colleague Lars Mattson. The course material is here.

I had the wonderful opportunity to teach for one hour in a one day crash course on the Magentic Universe organized as a part of the ASI meeting in 2015. The meeting was organized by Kandaswamy Subramanian and Dipankar Bhattacharya. Here are my very short lecture notes.

A five week long course give as a graduate course in astronomy department of Stockholm
University. The emphasis in this course in on * scientific computing * not
fortran. Although you may even be able to learn neat tricks in fortran from the course
material.

I have taught this course twice. Unfortunately, I do not have complete lecture notes from either times. The first time I taught this I had all the hand-written lecture notes scanned but due to a crash of the nordita server in Dec. 2010 I lost most of it. Whatever could be salvaged is the following:

- Latexed lecture notes as pdf file. Be warned that some of the links in this file might not work.
- Lecture 3 (handwritten and scanned)
- Lecture 4 (handwritten and scanned)

The second time I taught the course I was less careful. So I do not have much material saved from that time. But whatever I had is available here. Maybe I shall get a chance to teach this course again in future and then I shall be more careful in keep records.

Handwritten and scanned lecture notes delivered at SERC school in Kolkata December 2006. There were introductions to three different trends of present (at 2006) day turbulence research. These are not "stand-alone" lectures. Accompanying lectures were deliverd by Rahul Pandit and M.K. Verma. The pdf file of the scanned notes are here. There notes were strongly influenced by lectures deliverd by K. Gawedzki in Warwick where I was a student. If you are a beginner in turbulence research I strongly recommend the set of original lectures to you.
