PHYS-4007/5007 Web Page of Tutorials

This web page contains the links of the various tutorials to help students learn how to use computers to carry out scientific research. Some of these tutorials work with various programs and script files that you will need to download to the computer you are using in Brown Hall 264. In addition, there are various help files you can use to help you in your programming experience.

Weekly Tutorial Sessions:

Each week throughout the semester there will be one class session that meets in Brown Hall 264 for the students to work on various tutorials that will give the student experience in both creating/modifying operating system script files and programming language files of the programming languages we will be using throughout the semester. For this Fall 2025 semester, these sessions will take place on Tuesdays from 11:45 a.m. until 1:05 p.m.

Note that during the first week of class, we will not be doing a tutorial, but instead, be filling out a survey form so that Dr. Luttermoser has that information to set up your user accounts on the Linux computers. Note that each of you will have accounts with a username associated with the student on all of the Linux machines in Brown Hall 264.
