Because of the freeze day last week, I have had to revise the syllabus. The links above will now take you to the revised version of the Syllabus. Note that assignment due dates and the midterm exam date have changed.

I have finished grading the midterm exam and I will pass it back in class today. To see the distribution of scores and comments on the exam click HERE. May 11, 2018
Final exams have been graded and scores have been posted to Canvas (look under assignments). Grades have been posted to Gibson. If you want to see your final exam or have any questions about your scores or grades, please feel free to come by my office, Room 208 Blessey Hall, or you can send e-mail. It is probably best to make an appointment, as I am in and out of my office now that the semester is over.
What truly is amazing is that many of the comments below are the same comments I posted after the previous semester's final exam and have been posted on this web site during the entire semester. One good thing - Everyone in the class now knows that magmas do not come from the liquid outer core of the Earth. So, I can now retire.
Here are some general comments on the exam: Two primary goals that I have in this course are to provide information that will help save your lives and to bust myths people have about historic events or the way things operate. The bad thing about final exams are that they are final - people don't know what they did wrong, and thus walk away believing things that are just not true.
Life or Death Questions Several questions on the final exam were designed to see if you learned some valuable life or death lessons. The results are discouraging.
That's 28 deaths in a course in which you were supposed to learn how of avoid deaths by natural disasters. Some people died more than once, but I did not keep track of those statistics. Hopefully those of you who potentially died in these situations will read about your errors here before reality strikes.
Congratulations to those of you who are graduating, and best wishes for a great summer to all.

Note: Two versions of each set of lecture notes are shown in the table below. The first is in html format, optimized for viewing on the Web. You can print this version directly from your Web browser, but there is no guarantee that the pages will break where they are supposed to, since each person's browser can be set up differently (margins, fonts, font sizes, etc.). The PDF (Portable Document Format) versions of the lecture notes are optimized for printing. All page breaks should occur correctly. If your web browser has the proper plug-in installed, clicking on the PDF will bring the file into your web browser from which you can then print the notes. If the plug-ins are not installed, your web browser will either attempt to download the PDF files or offer to send you to the Adobe web site to download the plug-ins for your browser. If you choose to download the PDF format lecture notes you will still need the free Adobe Acrobat Reader to view and print the files. This and further information about the browser plug-ins can be obtained by clicking on the icon below. Special Note on Fonts- Some web browsers use a different method to display the Symbol font which I used for creating Greek Characters like - Δ Σ α β etc. If these characters do not show up as Greek characters, your browser has this problem. The alternative is to use a different browser to view the html files or to use the PDF files where all fonts are rendered correctly. |
