A solution for today's exam can be found here. It is possible that it will be modified / extended with additional comments after we have corrected the exam (e.g. if we find unexpected solution methods or misunderstandings)

Note that at the end of most questions there are comments on what it takes to get full score. This is meant as an explanation to you (a step towards "automatisk begrunnelse"), as well as a guide to the people who will be correcting.

Now go relax and have a nice summer! Thanks for all your hard work and enthusiasm!

Upon request, I have posted the usual type of summary slides for the very last lecture (week 15) -- i.e. solution of PDEs by Fourier transform, and orthogonal functions. 

Fysisk Fagutvalg is organising an exam workshop for FYS3140 where you can get help preparing for the finals. Henrik and Eirik (the problem session teachers) will be present. 

Time and place: Tuesday May 22, 16-18 in Lille Fysiske Auditorium (2nd floor west wing)

Just a reminder that the list of permitted supporting material for the final exam is found here:

http://www.uio.no/studier/emner/matnat/fys/FYS3140/index-eng.html#exam

You may write your 4 pages of notes by hand or electronically, as long as the fonts are large enough to be readable without a magnifying glass... But it is more important to think thoroughly through what are the central concepts that should be on the notes, than squeezing in the maximal amount of text/formulas.

Remember, you are qualified for the final exam if you a) Handed in the home exam (this year!) and b) Passed at least six weekly assignment (this year or during the past three years) 

The last lecture is planned to be on Tuesday May 15. (With May 22 as a backup in case of illness or similar).

We will finish up PDEs and orthogonal functions (including the problem that is also part of problem set 13). Then I will give a summary of the course with some reminders how to best prepare for the exam.

Unfortunately there is no time for Laplace transforms because we lost a couple of weeks due to illness and public holidays. Also, we won't go into the Poisson equation in any depth. So section 13.8 (including problem 13.8.7) is for voluntary self-study.

In the "worked examples" notes I have added an example that explains the method of using Fourier transforms for solving PDEs. This example will be discussed in the next lecture. But if you are not attending lectures, study it in the notes!

I have posted problem set 13 which is mainly about PDEs. It is not for handing in but just as important as the other problem sets.

I have also posted a folder with exam problem sets and solutions from the previous years (one of them is part of problem set 13). You are very much encouraged to use these to practice and familiarise yourself with "typical" exam problems.

Finally, I have posted a short note on orthogonal functions, which will be lectured at the end of PDEs.

LAPLACE TRANSFORMS: This is usually an important part of the course. Unfortunately we have lost several lectures this year due to public holidays and illness, so I will have to see next week to what extent I can fit this in at the end. If I find the time to lecture Laplace transforms, some problems and info on chapters will be posted. Otherwise it will be taken out of this year's curriculum. 

The results of the home exam have been posted. You are only given a score, no grades at this point. This result will be combined with that of your final exam later.

Some examples of where points were frequently lost:

* No arrows on integration contour

* Not performed a proper ML-estimate in 2Bb

* Unnecessarily complicated/messy calculations or arguments or very sloppy/unprecise/wrong use of terminology (when revealing lack of understanding) 

In general we are stricter here than in a final exam when it comes to precise language, correct use of limits, terminology and similar.

I have updated the "Examples" compendium with some material on Fourier transforms, relevant for the next couple of lectures. Have a look! :)

Sorry, typo on PS10.The deadline is Monday as usual. So, April 23.

At today's lecture, about 40 students filled in the questionary to give feedback on the course so far: Information, organisation, time consumption, level of difficulty, home exam, and whether there should be numerics (programming) in this course. Thanks for your help! Here are a few points worth mentioning:

* In general people seem to be very happy with the course which is nice :)

* There is a good spread in peoples' opinion on the level of difficulty of the course and home exam, fram "too easy" to "very challenging". Given that this course nowadays has very many students from different semesters, study programs, background, we naturally cannot hit the perfect level for everybody. So I think this is the best feedback we can hope for. But perhaps should have included at least one much more challenging problem in the home exam?

* An overwhelming majority thinks that the course is best WITHOUT programming/numerics. This agrees well wi...

A hand-written solution for the home exam has been posted. Correcting will probably take a couple of weeks. After we have a better idea of typical difficulties, misunderstandings, alternative solutions you have found, we may post additional comments or an updated solution.

See link under "Problems and Solutions". Please read the instructions carefully. Good luck!

The lecture note on differential equations has been updated with an additional example on Green's functions.

First of all, I have already posted problem set 8 (due 19/3) and 9 (due 9/4) so you can divide your time as is most convenient to you.

The next few weeks will be as follows:

Calendar week 12 (19-23/3): Midterm week. No classes in FYS3140

Calendar week 13 (26-30/3): Easter break. No classes

Calendar week 14 (2-6/4): Public holiday Monday, regular classes otherwise

Calendar week 15 (9-13/4): Home exam in FYS3140. No classes

The HOME EXAM will be posted around 4pm on Friday April 6. Deadline for hand-in will be Monday April 16 in the morning (probably 10am). You will need to hand it in on paper at the physics front office.

NB! It should NOT take you 10 days to solve the home exam... I am just giving you plenty of extra time so you can divide your time, still work properly with your other courses, and to make things flexible e.g. for the students going to CERN.

A slightly updated version of the lecture notes on ODEs has been posted today. The only difference is that an example has been added on p.4

Devilry has now been set up, and you should hopefully be able to hand in problem set 1. Deadline Monday 29.1. (before midnight)

I have posted a file with examples. These are worked examples with comments directly relating to the lectures (and will thus not be done on the blackboard). They are supposed to help you digest the material either when preparing for the lectures, when going through your lecture notes, or if you are not attending lectures. The notes will be updated and grow as the course progresses. So far the examples are for the two upcoming lectures. Feel free to notify me of typos :)

Unfortunately the lecture tomorrow (Tuesday) will have to be cancelled too. But don't worry, the spring semester is long, and we'll soon get back on track..  

Unfortunately, thanks to flu season, there will be no lecture today (Monday). I hope tomorrow's lecture can take place -- but please stay tuned here for updates tonight/tomorrow morning! 

Meanwhile, please study sec. 14.1 - 14.3 in the book so that you come prepared when I explain the material. This will allow us to speed up a little :) 

PS The problem sessions will take place as planned.

The student representatives for FYS3140 this semester are:

Cecilie Glittum cecilgl@student.matnat.uio.no

Veronica Danielsen danielsenveronica@yahoo.no

You can contact them if you want to bring up issues relating to the course, and they will participate in the final evaluation in June.

The home exam is planned for week 15 (tentatively April 6-13). No classes in FYS3140 that week.

Also, there will be no classes in FYS3140 during week 12, when most other courses have their midterm exams.
