GLG 410 Computers in Geology. (3) Geological computer skills including data processing, visualization, presentation, numerical analysis, software and hardware applications. Satisfies General Studies CS Requirement: (computer/statistics/quantitative applications (CS) applies mathematical reasoning and requires students to complete a course in either the use of statistics/quantitative analysis or the use of the computer to assist in serious analytical math work)

Why Computers in Earth and Space Exploration? We try to understand the physical processes that operate within and on the earth and other planets and to interpret the history of geologic events, evaluate active events, and anticipate future ones. To do so, we use the conceptual tools of physics, chemistry, biology, and mathematics and our (geo-) scientific intuition. As we work, we often gather and need to manage datasets. To progress in our understanding, we compare them with other datasets and with conceptual or theoretical models of how the earth or other planets work. Computers help us to learn about and gain intuition related to our conceptual tools, and they help us to manage and manipulate our datasets and often to generate predictions that we compare with our data (Hypothesis-testing). Computers in themselves are only the means to get to the understanding, evaluation, and anticipation that we seek. We have to be careful to be scientists (geoscience leads the activity), rather than technicians (the method or tool or computer leads the activity).

Practically speaking, there are many different angles to the question of what should (geo-) scientists know about computers and their use. I think that you can put it two ways: 1) knowledge of the specific applications and mixtures of applications necessary to gather and manipulate data and models and to present the results, and 2) knowledge of the general role of computers in our society and in the world today. There is a growing gap between the people who understand and know how to use computers, and those who do not. You need to be on the side of the former. A related and important topic is what we should know about mathematics, biology, physics, and chemistry. Computers are increasingly part of the practice of math, biology, physics, and chemistry, and thus earth and space science

A dilemma that we see for this course is where we should put our feet between specific applications, general literacy, and analytical tools. We will try to steer the class somewhere in the range of equal time among these, with a slightly greater emphasis on the analytical aspects because that can be harder to learn by yourself.

Objectives, approach, outline, and grading

This course is designed to teach analytical thinking in earth and space exploration using computing applications. As such, it is intended to satisfy the University's General Studies CS requirements. The class is aimed at the advanced undergraduate and beginning graduate students in our school.

The modular approach permits the course to focus on different science problems varying from hardware and data input/output, Internet applications, 3D visualization, simulation, and presentation of results. At the end of the course, the students are expected to be able to solve earth and space science problems using computers. Therefore, they should be familiar with operating systems, typical software applications, and the basic programming tools of the Internet, visualization, and simulation.

The 3 credit hour course consists of two days of 2 hour combined lectures/labs.

Grades are 70% for quizzes, lab, and homework exercises and 30% for a project presented to the class.

Grades will not be assigned on a curve. There is not a predetermined number of As, Bs, or Cs. You are competing against my expectations, not your classmates. We have different expectations for graduate students taking this course. We will occasionally post point totals so you can see how you are doing. The way to get a good grade in this course is consistent productivity. Don't miss any assignments, and keep up with the lectures, the labs, and the reading. If you have questions or difficulties, come talk to us.

We entertain valid requests for extensions of homework deadlines. However it is in your best interest to get the homework done on time. Unexcused late homeworks will be assessed a late penalty of -10%/day that they are late.

Note: Any student who feels that he or she may need accommodations for any sort of physical or learning disability, please speak to me after class, make an appointment to see Ramon or David.
