This course will initially focus on mathematics related to
the media. We will study media behavior using game
theory, information theory, probability theory, the theory of networks and differential equations.
The latter part of the course will be about applying probability theory and differential equations
to understanding various questions arising from the covid-19 epidemic. Here are some particular
questions we will study:
- If one knows the outcome of a medical test, what is the probability the answer is actually correct?
- How can we correctly update our prior estimates on the probabilities of various events based on new information?
- What degree of social distancing is needed from different parts of the population is needed in order to change the extinguish a pandemic?
How can people gauge their own success in achieving this?
- How do mathematical models of an epidemic actually work?
- What is the physics behind person-to-person transmission of various kinds of diseases? What does this say about
how to avoid such transmission?
- On Bullshit by Harry Frankfurt,
Princeton University Press, 2005. ISBN 0-691-12294-6. This book is available
- This book gives a careful philosophical analysis of bullshit. The main
distinction Frankfurt draws between lying and bullshit is that liars know
the truth and are concerned that their listeners believe something false.
Bullshitters are much less concerned with the truth value of what
they are saying, or that their listeners literally believe them.
They are instead focused on bringing about some
other reaction in their listeners, e.g. that the listener will support them
in some way. This book has many useful insights, and a good college
education should include developing the ability to recognize
and classify bullshit. Developing a mathematical
theory to go along with Frankfurt's philosophical approach is a main goal of this course.
In particular, mathematical game theory will help answer Frankfurt's question about
why there is so much bullshit in our culture.
- How math can save your life by James Stein, John Wiley and Sons, 2010.
ISBN 978-0-470-43775-9. This book is available from
- Stein's book gives a better introduction to game theory than many
textbooks, and it is written in a far more interesting way. The book
includes many amusing topics, and is an excellent example of
how with a little imagination one can view many real life situations
in a mathematical way.
- For All Practical Purposes
W. H. Freeman, U.S.A.. ISBN: 1-4292-0900-3
- This book
It's not necessary to obtain access to the online materials connected with this book. As far as I can tell, the later editions of the book do not really add value, and cost much more.
- Probability and Statistics 4th Edition
Addison Wesley, U.S.A., ISBN: 978-0-321-50046-5. Authors: Morris H. DeGroot and Mark J. Schervish
- This book gives an exceptionally clear description of basic probability theory and statistics. I recommend googling "deGroot statistics" in order to find various options for obtaining this book.
In the first part of the course we will study half-truths using mathematical, philosophical and empirical perspectives.
The mathematics needed involves the connection between game theory and linear programming
as well as methods for solving linear programming problems. The course will involve developing
and analyzing mathematical models and constructing rigorous mathematical proofs.
Because the course will involve the use of vectors in three dimensional
space and some linear algebra, math 114 is a prerequisite.
The second part of the course will concerns probability theory and differential equations relating
to the covid-19 epidemic.
Electronic and web resources:
We will be using several different kinds of software to talk about course material,
especially in view of the fact that the course will have to go entirely online after spring break.
- Before class, please look a the video that will be posted for the lecture that day on
the Course Schedule page. It will be very helpful if you note down any
questions you have about the video before we meet online to discuss it.
- The main tool we will be using for online classes is Zoom. You can obtain a free copy
of this by clicking on this link and downloading the
appropriate version for your browser and-or phone. We will be meeting in two groups on Tuesdays and Thursdays.
The first group consists of all people in class whose last names begin with Aa through Ol. I will
send an e-mail invitation to the first group a little before 1:30 p.m., and we will discuss the
day's topics till a little before 2:15. I will then send an e-mail to the second group
consisting of people whose last names begin with Or through Zz. I will send an invitation to the second group
a little before 2:15 p.m. and we will continue through 3:00 p.m..
- A backup application we will use is Skype
in the event that there are problems with Zoom.
By appointment and by Zoom and Skype in the evenings.
How to make attending lectures efficient:
Before each lecture, check the
current homework and lecture schedule. This will contain
readings for each day as well as videos about the content to be discussed in class. There will
also be links to homework problems.
Each homework will have a due date. You will need to send your homework directly
to the grader for the course, Hao Zhang (firstname.lastname@example.org). You can do this
by either typing your homework, writing it out on paper and sending a picture, or scanning
it and sending a scan. Hao will send your homework back to you by e-mail.
We will discuss the homework during our online sessions, and I would encourage you
to discuss it with other students as long as you write up your work yourself. A good procedure is to try the work first on
your own and then go over it with others.
Because of covid-19, the mid-term exam given on March 3 will be the only exam given in the course.
I'd originally planned to have a writing project take the place of a final exam. Because of the difficulty of groups
of people getting together to work on such projects, we will instead move to having the rest of the course
based on homework assignments.
You are very welcome to arrange a time to meet with me online to discuss the course.
Approximate Grading Weights:
75% -- Homework
25% -- Midterm exam Tuesday, March 3, in class.
