• Please remember to review the course objectives, on the information page at least once each week.
• I have created a few forum topics in OnCourse. Please go there for online discussions of physics topics with your colleagues. I will comment occasionally, but the forums are mostly for you to interact with one another.
• I have added a resources page. The link is at the bottom of the navigation bar on all of the 251 site pages. The resources page gives links to online learning tools including lecture videos, simulations, concept maps, and more.
• Please read the course information sheet, syllabus, assignment sheet, and objectives, on the information page.

• A few more hints about doing well in college

• Science history: On November 13th, 1971, the Mariner -9 probe entered orbit around Mars, becoming the first man made object to orbit another planet.
• Technology history: November 15th, 1928. The Wabash Railway began testing the first train car designed to detect defects in the track. The system operated by running a large electric current through the track, and using search coils to detect perturbations in the magnetic field produced.
