Mathematics can often seem intimidatingly abstract.
"Why do we need to know this?" and "What is this good for?" are common
questions, which sometimes are not adequately answered.
It is all very well to say that mathematics is needed for cell-phone design, or
to make ultrasound images, or for Google to calculate page-rank; but explaining
exactly how it is used in any of these applications takes a great deal ot time.
The purpose of this course is to give examples of how mathematics can be used to
understand real world problems. It is restricted to students enrolled in Calculus I, Math 131,
so we will start with problems that only need pre-calculus to solve, and work up to ones that use
Do I need to be a math wiz to take this course?
No. The course is for students who are curious about how mathematics is used in the modern
world, and like learning.
Here is a tentative schedule. The first seven do not use calculus, the
next six do.
We may change some of these topics.
Basis for Grading
Grading will be based on classrooom participation, and a term paper.
The topic of the term paper should be chosen in consultation with the Instructor.
A preliminary draft should be handed in October 30th. This will be graded and returned,
and a final version should be handed in December 4th.
Classroom Participation (contribution to discussion): 20%
Term Paper - first draft: 30%
Term Paper - final draft: 50%
I do expect you to come to class every day, and to participate in class
I expect you to read the corresponding section in Korner's book. I may call on you at
any time to answer a question.
The Pleasures of Counting, by T.W. Korner
This is a lovely book. If you get bogged down in some section, it is okay to move on.
