Objectives
The main
objective of this class is to practice writing about
mathematics. All writing has to be done in the word processing
system LaTex (see resources below).
The mathematical writing will be based on
- The Poincare Conjecture,
by Donal O'Shea.
- Flatland:
a romance in many
dimensions, by Edwin A. Abbott 1838-1926.
- Videos of general audience lectures given by
mathematicians on related topics.
- Additional assigned reading.
- Discussions in class.
There will be group
projects, including a final presentation of the projects by each group.
Examples
of mathematical writing:
- Steven Strogatz ''Elements
of
Mathematics''
and some of his writings you find in the NYtimes.
- Eugene Wigner ''The
unreasonable effectiveness of mathematics in the natural
sciences''
- Paul Lockhart ''A
Mathematician's Lament" (specially recommended for anyone
who wants to teach mathematics)
- Robert Kanigel "The Man
Who Knew Infinity: A Life of the Genius Ramanujan"
- G. H. Hardy
"A Mathematician's Apology"
- Simon Singh
"Fermat's Last Theorem"
- Timothy Gowers "Mathematics. A Very
Short Introduction"
- Edward Frenkel "Love and
Math"
- Roger Penrose "The
Road to Reality"

Course
Log and assignments:
Week
1:
Download the full latex installation on your laptop from the
links in the resources section (mac users and Microsoft users need
different installations---those who run Linux can fare for
themselves, since they know better anyway). Familiarize yourself
with its basics by using the templates provided above. Get help
from fellow students if you have difficulties or google your
questions. All writing in this class has to be done in LaTex.
Reading
Assignment :
Paul
Lockhart "A
Mathematician's Lament".
Writing
Assignment due 9/19/2019:
Write an essay (minimum 1 page single spaced in latex) how your experience
with math so far compares to Lockhart's view of mathematics and how
it should be taught. Consult the writing
check list before
you hand in your essay.
Week
2: Discussed the exploration of earth and how
humans eventually came to understand its shape.
Make sure you have latex up and running seamlessly.
Reading
Assignment :
"The
Beauty of Doing Mathematics" the first hour of the lecture by
Serge Lang, titled "The great problems of geometry and space". Then
read the first 2 chapters of "The
Poincare Conjecture" by
Donal O'Shea (the book is a rather large file, so be patient when
downloading via slow servers).
Writing
Assignment due 9/26/2019:
write a 2-3 page singly spaced essay for
say the campus news paper (i.e., your essay should be accessible by all
students and faculty) on how the Greek geometer Eratosthenes (275-195 BC)
concluded that he earth was round and how he
calculated its circumference to great accuracy. Provide some biographical
detail of Eratosthenes and enough
mathematical detail for readers to follow the calculations. Include some
drawings to aid explanations etc.
Week
3: Discussed the notion of a manifold, boundary,
compactness, and simply connectivity.
Reading
Assignment :
"The
Beauty of Doing Mathematics", the second hour, pg.
96--106, of the lecture "The
great problems of geometry and space" by
Serge Lang. Also read
chapters 3 and 4 of "The
Poincare Conjecture" by
Donal O'Shea (the book is a rather large file, so be patient when
downloading via slow servers).
Writing
Assignment due 10/3/2019:
write a 2-3 page singly spaced essay for
say the campus news paper (i.e., your essay should be accessible by
students, faculty, and the occasional reader from town) what it would be
like to live on a 2-dimensional world.
For instance, how does a triangle, square etc. look like to a
2-dimensional being. What kinds of 2-dimensional worlds can you imagine
other than the plane? Try to express concepts such a finitely extended, or
infinitely extended, boundary or no boundary etc. so that readers get some
idea what it is about.
Week
4: Discussed the 2-dimensional Poincare conjecture:
surgery and boundary gluing. Watched Carl
Sagan's Flat Land video. Listened to an interview with Roger
Penrose on ``What
things exist'' (make
sure you select the ``long interview").
Reading Assignment :
"The
Road to Reality"
by Roger Penrose. Read the
Introduction, Prologue, and Chapter 1.
Writing
Assignment due 10/10/2019:
write a 2-3 page singly spaced essay on
what you took away from the interview and the subsequent reading. You may
want to include your own viewpoint on the topic of mathematical reality
versus physical and mental realities.
Week
5: More on surgery and boundary gluing.
Listened to an interview with Roger Penrose on ``Is
mathematics invented or discovered?"
(make sure you select the ``long interview"). Also watched a
lecture by Curtis McMullen on "The
Geometry of 3-manifolds".
Reading
Assignment :
Chapters
5 and 6 of "The
Poincare Conjecture" by
Donal O'Shea.
Writing
Assignment due 10/17/2019:
We
now
had many occasions where we described the 2-sphere as two disks glued
along their circle boundary. Use stereo graphic projection from the north
resp. south poles to explain this model of the 2-sphere in terms of two
charts (the images of the stereo graphic projections of the two
hemispheres). Calculate explicitly the stereo graphic projection map and
its inverse. Also calculate the transition function between the two pages
of your atlas of the earth: the north pole projection and the south pole
projection. You will need to do some research on your own if you haven't
seen the stereo graphic projection before.
Week
6: Watched a lecture by Jeff Weeks on "Shape
of Space".
Reading
Assignment :
Chapters
7 and 8 of "The
Poincare Conjecture" by
Donal O'Shea.
Writing
Assignment due 10/24/2019:
Write
an
essay about Euclid and his importance in geometry. Explain the parallel
axiom and why this was controversial for a very long time and how it got
resolved.
Week
7: Tiling by regular n-gons of the
Euclidean plane: the flat architecture of the doughnut.
Reading
Assignment :
Chapters
9 and 10 of "The
Poincare Conjecture" by
Donal O'Shea.
Writing
Assignment due 10/31/2019:
Go
over your stereo graphic projection paper and re-edit it with all
the comments I made in class:
- DO
NOT
MESS WITH LATEX!!! Do not underline, center etc. at your own whim. You
cannot improve (you can only destroy) the latex layout of a chosen
document style (maybe experiment with different document styles if you
are unhappy with the current one). Do not make your own section
headers, titles, or captions of images etc. Use the latex
environments provided for that. There also is an extensive
theorem/lemma/corollary/definition/conjecture etc environment if you
need to use that.
- Adjust spacing, image sizes
etc so that you get a good layout (no half empty pages, no large empty
spaces between paragraphs, or below equations, or between equations
etc).
- Think about your chosen notations
and keep them consistent throughout. Do this wisely. If you choose
italics P make sure it is italicized throughout.
- Text in math mode has to be roman
(use \text{...} to achieve that). Use the \sin, \cos etc for standard
functions. This will assure they get printed correctly in equation
mode.Most functions have latex symbols, look up latex math
function/symbols tables.
- NEVER copy and paste formulas from
the internet and include them as a picture file into your essay.
Typeset all formulas by yourself.Balance inline and display formulas
according to importance. Make sure you provide text between displayed
formulas/equations.
- If you include images have a capture
and refer to the images in the text. Pay attention to image size and
how this compares to your page layout. Try to get images as sharp and
readable as possible (usually achieved by high resolution images).
Avoid low resolution images from the web, search for high quality
images, or make them yourself, by using a drawing program (open source
like Gimp etc) or hand draw if you are artistically inclined.
- Use Google queries to find out how
things are done if you get stuck.
- If you are not sure about things and
have questions ask me during class, we can always make time to go over
it, some fellow students might have similar problems.
Week
8: Worked on the connections of Euclid's 5th axiom,
the parallel postulate, with the three architectures of compact,
connected, orientable 2-dim shapes: the round sphere (positively
curved architecture), the torus (flat Euclidean
architecture), and the higher genus surfaces (hyperbolic
architecture). We discussed tilings in those architectures and
noticed that there are interesting tilings of the sphere arising
from the Platonic solids.
Writing
Assignment due 11/7/2019:
Explain the Platonic solids, their
historical significance, their connections to the elements (water, fire,
etc.) in Greek philosophy. Then connect the Platonic solids to regular
n-gon tilings of the round sphere: you could try to proof (similar to
what we did for the Euclidean case), that the "puffed out" Platonic
solids are the only possible such tilings. For this, you would have to
explain the condition of a regular tiling on the sphere and etc. Try to
write a cohesive, informative, structured, and mathematically accurate
piece. The audience you should have in mind is the generic reader of,
say, a College news paper. Always check your latex and writing against
the week 6 rubric and the writing
check list.
Week
9: Discussed the hyperbolic plane and its
tilings by regular n-gons.
Watched a documentary about M. C. Escher narrated by Sir Roger Penrose:
The
Art of the Impossible: MC Escher and Me (2 parts on YouTube).
Writing
Assignment due 11/14/2019:
Write an essay about M. C. Escher
focusing on his usage of spherical, Euclidean, and hyperbolic geometries
in his art. Include the relevant Escher graphics and elaborate how they
connect to the relevant geometries. Always check your latex and writing
against the week 6 rubric and the writing
check list.
Reading
Assignment :
Chapters
10 (re-read in the light of the discussions in class), 11, and 12
of "The
Poincare Conjecture" by
Donal O'Shea.
Week
10: started
discussion of 3-dimensional shapes: Euclidean 3-space and various way to
think of the 3-sphere.
Writing
Assignment due 11/21/2019:
Define, explain and calculate the
relevant formulas for the stereographic projection from the 3-sphere to
the 3-dimensional equatorial space and its inverse map back to the
3-sphere. Write down your
understanding of it on the level of a math major. Check your latex and
writing against the week 6 rubric and the writing
check list. Make sure
your notation is consistent and formulas a properly typeset.
Week
11:
Discussed more the
3-sphere, the 3-torus, genus 1 handle body gluing resulting in the
3-sphere and S1 x S2, and Thurston's Geometrization
Conjecture (the 8 ``architectures" describing 3-dimensional shapes). We
watched part of Curtis
McMullen's lecture titled ``Mathematics
as Metaphor", and Jeff Week's lecture ``Shape
of Space".
Reading
Assignment over Thanksgiving: Finish
reading the book "The
Poincare Conjecture" by
Donal O'Shea.
Handcrafting
Assignment due after
Thanksgiving: choose your
favorite material and two of your favorite Platonic solids (not both
cube and tetrahedon) and build them as a model. Bring them to class
after Thanksgiving.
Week
12: Discussed the concept of
curvature of planar curves and surfaces. Showed curvature flow
experiments, all with the purpose to get some vague idea what Perleman
accomplished.
Writing
Assignment due 12/17/2019:
Write about your impressions of the
class: what you expected from the class, what
you liked/disliked about the course, what you thought of the
class and of the material covered, whether it helped you see a side of
math you had not seen before, whether some of it caught your interest,
suggestions of what to do differently etc.
