Announcements
Mathematical secrets of ancient tablet unlocked after nearly a century of study. This is the article from the Guardian I mentioned in class that was
hyping a discovery a little too much. For a better understanding of whether it impacts current math, I recommend the following article from Scientific American:
Don't Fall for Babylonian Trigonometry Hype.
Facebook Friends. Note: I recommend reading Steven Strogatz NYTimes article on this phenomenon.
Catalan Lecture handwritten. You can see the difficulties
(for me) of handling infinite sums by looking at all the things I had to crossoff in page 2.
Catalan TeXed Up is written in TeX. Much more professional
presentation. It can be useful to see the difference to remember that just because it looks
easy on the page, it doesn't mean it was easy to get there.
A birthday in St. Petersburg. This article covers what we did in class on Monday August 28, 2017.

Textbook
The main book we'll use is:
Journey through Genius by William Dunham.
Goals of the Class
The goals of this class are the following:
 Showcase the connections between different areas of mathematics.
 Prepare you to know how to give a classstyle lecture.
 Prepare you to write mathematics professionally (using LaTeX).
 Prepare you to give a presentation in Beamer (a package in LaTeX).
 Connect with the recreational side of mathematics.
 Be able to read mathematical papers of a level just below research level.
Grading
The course grade will be based on:
Class Presentations 
35% 
Beamer Presentation 
20% 
Paper 
25% 
Halloween Colloquium 
10% 
Homework 
10% 
Senior Assessment 
0% 
Class presentation
The class will form into groups of 2 (or 3 if necessary). The groups will be assigned two chapters
from the book Journey through Genius and they will present each chapter to the class over two class
periods (two class periods per chapter). The students not presenting will have to attend and they will provide
feedback to the presenters by the next class session. I will also get a copy of this feedback.
For the second presentation, students should go beyond the text and be ready for questions that can come up for a
person reading the text. For example,
some questions from Chapter 2 which are relevant are:
 The chapter talks about the "collapsible" compass and how Euclid proved that you did not need to assume that you could
fix a compass to a length to
use it elsewhere. How does Euclid's proof work? (note this proof is not in the book, you'd have to find it elsewhere or
figure it out on your own.)
 The book mentions proposition I.5 is known as the "bridge of fools" because the diagram vaguely resembles a bridge and
many people have trouble
understanding the proof. What was the diagram? What is the proof?
The grade for an individual with regard to the class presentation will depend on the presentations (25%) and the feedback they
provide to the other teams (10%).
Schedule for the Presentations.
Beamer presentation
 Each student will find an article they like from the series of anthologies The best writing on mathematics edited by Mircea Pitici. The whole
series is on reserve. The 2011 edition is also available as an ebook, which can make things easier for the student.
 The student will send their top three picks to me via email by September 24. After I collect all picks, I will assign a student with an article they ranked.
 The student will then write a Beamer presentation and give a 15 minute presentation about the article in class. A Beamer presentation is like
PowerPoint but written with LaTeX. It has the advantage of making mathematical formulas prettier.
 Every student will give feedback on the presentations of the other students.
The presentations will be twoaday in mid October in the same order as the team presentations. The schedule will be here.
The grade for an individual with regard to the Beamer presentation will depend on the presentation itself (15%) and the feedback they provide to the other
students (5%). Note that this presentation is not a team presentation. Using Beamer correctly will be part of the grade.
Paper
For the paper, you have to find a subject on your own and write about it. The assignment has the following rules:
 First, pick a mathematical subject. It can be a cool puzzle, an interesting game (that involves thinking),
an application of mathematics to
some field (maybe an application of math to sports) or an exciting theorem.
 Once you pick your subject, find three references to give you background on that subject.
 Send the subject and the three references to my email by November 1st . I will then approve the topic, if it is suitable.
If not, you have to find one right away. I suggest you have three subjects in case I don't approve one of them.
 Once you have my approval, write a paper talking about the subject. Your paper should be between 3 and 5 pages long (doublespaced with 12
point font). You can use the "Best Writing In Mathematics" articles as examples of how to write good math articles.
You are welcome to include pictures and you should include a bibliography. The first draft is due on November 13.
 The paper has to be written in LaTeX. You will send me the .tex file and you will print 4 copies of your pdf (1 for me and 3 for 3 students).
 After getting feedback from your peers (by November 20), you will write a final draft and turn it in on December 6.
Your assignment also includes reading the drafts of three other students and give them feedback so that they can improve their final draft.
The comments you write should be written seriously and be helpful.
The grade for an individual with regard to the paper will depend on the first draft (10%), the final draft (10%) and the feedback they provide to the other
students (5%). The aesthetic presentation of the paper will be weighed in as part of the grade.
LaTeX and Beamer
As described above, the final paper should be written in LaTeX (and compiled to a pdf) and the individual presentation should be written in a special LaTeX package
called Beamer (also compiled to a pdf). Below I include links to useful manuals, websites and also templates for LaTeX and Beamer.
 Slides from a talk on LaTeX created by Vadim Ponomarenko of San Diego State University.
The TeX source code for the slides. (Rightclick to Save Link As).
 LaTeX on Wikibooks. A very useful online manual.
 For PC users, you can use TeXnicCenter to compile.
You'll need to install MiKTeX. After you install MikTeX, you wil also have TeXWorks in your computer. You can use
this compiler instead of TeXnicCenter if you prefer. Or find your own.
 For Mac users the things to install are different. You can use MacTeX or find one of your liking online.
 Another option is to compile things online in Share LaTeX. Many of my students have liked how easy
it was to use.
 Similar to ShareLatex, the computing software Sage which is free online also has a LaTeX compiler online.

 Example of a Beamer file of mine in TeX and the corresponding pdf.
Halloween Colloquium
Working in groups, students will prepare a short sketch of a mathematical paradox or a puzzle to present in the annual
Halloween Colloquium of the Math/CS Department. The colloquium is at Noon on Monday October 30.
The groups will have to present to me their plans at least a week before the Halloween Colloquium and do a trial run in class on Friday October 27.
The grade for an individual with regard to the Halloween Colloquium will depend on the presentation itself (10%).
Homework
I will post a homework assignment for each presentation from Journey Through Genius. Students need only turn in
homework assignments for 5 of the assignments, they get to choose which ones they want to turn in.
Homework
Senior Assessment
To pass the course, students have to take an assessment exam on the day of the final, which is on Wednesday
December 13 from 8:30am to 11:30am. The assessment counts for 0% of the grade, but if a
student fails to do it, he/she will not pass the class.
Writing Center
The Writing Center offers free tutorial assistance, information, and
resources for every stage of the writing process.
In the online scheduler you can set up an appointment with a writing center tutor.
You can also set up a standing appointment (to meet every week at a set time) and you can also have access to a lot of resources the writing center has
online.
Accommodations Statement
If you believe that you need accommodations for a disability, please consult with The Learning and Teaching Center.
Since accommodations may require early planning and are not retroactive,
please contact the center as soon as possible. For details about the services for students with disabilities and the accomodations
process, visit http://www.lakeforest.edu/academics/resources/disability/.
You are also welcome to contact me privately to discuss your academic needs. However, all disabilityrelated
accommodations must be arranged through Teryn Robinson at the Learning and Teaching Center.
