3. Engineering "For Dr. Petroski, acceptance of uncertainty and possible failure - he calls it "coping with the imponderable" - is what separates the "given world" of the scientist from the "built world" of the engineer." (From the May 2, 2006 New York Times article about Henry Petroski of Duke University (page D3)) Fellow of the American Society of Civil Engineers Member of the American Academy of Arts and Sciences Member of the National Academy of Engineering.

5. Professor William P. Clement Associate Research Professor Center for Geophysical Investigation of the Shallow Subsurface (CGISS) Math/Geosciences 206B http://cgiss.boisestate.edu/~billc billc@cgiss.boisestate.edu 426-4307 Office hours: Friday’s Engineering 110 Available in my office, MG206B most of the time except during exercise hour (11:30-2:00)

6. Who Am I? I am a geophysicist – a geoscientist who uses physical principles to understand the structure and processes of the Earth. I use FM frequency radio signals to produce images of the upper 20 meters of the Earth. I have been a research professor at Boise State University since 1997. Hopefully, my background as a scientist will provide context to this course.

7. Geophysical Tomography

8. Borehole Tomography Experiment

9. Borehole Tomography We know the physics of the problem and the data and we try to find the model parameters.

11. Course Aims and Objectives Precalculus: foundation for calculus (Math 170 and 175) Concepts and methods fundamental to: Math Engineering Much of engineering math is taught here Learn it now - avoid later struggle - enjoy engineering

12. Course Aims and Objectives Determine how you learn best: - Visually - Listening - Reading - Combination What is important is that you: learn how to learn learn how to enjoy learning

13. Course Aims and Objectives Processing information is the key to learning. I can transfer lots of information to you (tell you the information), but until you process it, until you work with it, you will not develop a deep understanding the information.

14. Class Format and Procedure Math 147 - lecture course - self-learning through ALEKS on your own (mostly) in ENGR 110 Learning Community You must be registered for both courses to participate in this section (section 008) of Math 147.

15. Class Format and Procedure Quizzes and exams Fridays during Engineering 110 Homework working through ALEKS - on your own - Friday’s Engineering 110 class - after quiz or exam

16. My View on Mathematics I view mathematics as a language. Mathematics is often the best way to present engineering and scientific theory. Learning mathematics is not the end goal of this course. The goal is to be sufficiently comfortable with mathematics so that you can focus on new engineering concepts without being confused by the mathematics.

17. Your Challenge in Mathematics But being comfortable with something means using it frequently and understanding its nuances. You must spend significant time practicing simple, repetitive problems to fully understand the beauty of mathematics.

18. What You Really Care About:Grading Homework and Quizzes – 30% Exams (5 during semester) – 55% Final exam – 15%

19. Grading Quizzes and exams will be delivered through ALEKS during Friday’s Engineering 110 class For the exams only, you will write down your work - for credit for the exam (i.e., you took it) - for partial credit Missed exams or quizzes: Do not miss them! - Drop 1 (one) quiz (i.e., your missed one) - Exams – let me know beforehand better have incredible excuse

29. Course Aims and Objectives Precalculus lays the foundation for successful completion of Math 170 and 175. The concepts and methods learned in this course will form the fundamental basis for further studies in math and, most importantly for you, in engineering. Much of the math you will do in engineering is taught in this course. Learn it now so you can avoid struggle in upper level classes later.

30. Course Aims and Objectives You need to determine how you learn best, for example, by seeing the information, hearing the information, or reading the information. You might do best with a combination of different methods. What is important is that you learn how to learn and you learn how to enjoy learning.

31. Course Aims and Objectives Processing information is the key to learning. I can transfer lots of information to you (tell you the information), but until you process it, until you work with it, you will not develop a deep understanding the information.

32. Formats and Procedures I expect you to attend class and to participate by being actively involved in class. The simplest way to be involved is to think about why a topic or method is being presented. What is the purpose of posing or solving the problem this way. Ask questions if you do not understand something. Do not be afraid to ask a question. If you do not know the answer, many other students will not know the answer too! If someone is brave enough to ask a question, I expect you to honor their bravery by showing respect to your classmate.

33. Formats and Procedures I view mathematics as a language that more concisely and accurately conveys and describes engineering and scientific concepts. Mathematics is often the best way to present engineering and scientific theory. Thus, learning mathematics is not the end goal of this course. The goal is to be sufficiently comfortable with mathematics so that you can focus on new engineering concepts without being confused by the mathematics. But being comfortable with something means using it frequently and understanding its nuances. You must spend significant time practicing simple, repetitive problems to fully understand the beauty of mathematics.

34. Formats and Procedures Math 147 is primarily a lecture course combined with self-learning through ALEKS. This course is part of a Learning Community which includes Engineering 110. You must be registered for both courses to participate in this section (section 008) of Math 147. Attendance in both courses is beneficial to successfully passing Math 147. Quizzes or exams will be delivered most Fridays during Engineering 110. Homework for Math 147 consists of working through ALEKS on your own and during Friday’s Engineering 110 class after the quiz or exam.
