This is NOT an internet course. Necessary details and calculations, missing from the text in the book, are lectured. The exercises are essential. If you cannot participate, you had better arrange so that somebody present provides you with notes!

Aud. R73 is not easy to find (4th floor, Realfag E, near main entrance)!!!!

The first lecture will take place on Monday the 8th of January in R73, 14.15–16.00
The first exercises will take place on Tuesday the 16th of January in S21, 16.15–17.00

See below about the Exam.
