Location
We are currently located in Wong 0120 in the basement of the Wong Building.
Calendar Entry
(3 credits; 6 hours)(Prerequisite: 198-241B) Introduction to modern techniques of measurement. The use of computers in performing and analysing experiments. Data reduction, statistical methods, report writing. Extensive use of computers is made in this laboratory; therefore some familiarity with computers and computing is an advantage.

Lab Reports
- Lab Report Marking Scheme (http://www.ugrad.physics.mcgill.ca/resources/339/PHYS339-2011-Marking_Scheme.pdf) - Marking guidelines for reports detailing breakdown of grade. .=* NEW *=.
- Lab Report Checklist (http://www.ugrad.physics.mcgill.ca/resources/339/checklist.pdf) - PDF document listing questions you should be able to answer yes to if you don't want to be penalized for technical issues. If you answer no to one of these questions, you need to have a really convincing answer to the follow up question "Why not?".
- Report Guidelines (http://www.ugrad.physics.mcgill.ca/resources/339/report_guidelines-2011.pdf) - This not so crusty description of what is expected in the structure of the report. Written by DHR, deviate at own risk.
- General Report Comments (http://www.physics.mcgill.ca/~voyerc/reports_339.pdf) - A short list of comments relevant to the particular class to date. Most information within is included in the report guidelines with a few stylistic additions.

Remote access
You can access your workstation via SSH. The fully qualified domain name is ws339-nn.ugrad.physics.mcgill.ca, where nn is the workstation number.
This may be covered elsewhere in the Wiki, but you can access the Windows_Storage subdirectory of your home directory via the information superhighway at the following service station:
- https://webfolders.mcgill.ca/students/dasusername
Last time I checked it was not very reliable.
General Lab Report Comments From The TAs
Left for posterity:
Stephen and Christian have supplied a few general comments on the lab reports you may find useful. They include mostly issues that come up quite often and that can not only be easily avoided, but will not go unnoticed.
