The top 15 highest-earning college degrees all have one thing in common -- math skills.
Note to prospective graduate students.
I no longer intervene directly in the graduate application process in either Mathematics or Computer Science.
I have no direct support for graduate students, nor do I offer summer internships. There are online instructions about how to apply for the graduate programs in
both the Mathematics and Computer Science Departments. I'm sorry, but
I will no longer reply to e-mails from prospective students.
A complete list of my papers can be found on my "bio" page
. You can download various papers by me and my previous students on image processing and wavelets and
numerical methods for partial differential equations and related topics.
High quality, grey-scale, test images for purposes of testing algorithms on natural images. Some results from my compression program are given.
The original Kodak Photo CD Photo Sampler color images from which the greyscale images above were derived. If anyone can tell me a standard way to convert these to YUV, YCrCb, or RGB, I'd be interested. Later note: it seems that various versions of Photoshop have good color conversion between Kodak Photo CD format and RGB, so that is what I used for the color versions. I'm still not happy with Photoshop's conversion to grey-scale. New: You can find a lot of useful information about working with Photo CD images at Ted's Unofficial Kodak Photo CD Homepage.
- Software for the numerical approximation of solutions of elliptic and parabolic partial differential equations (from CS 615).
- Schelog, an embedding of Prolog into Scheme that was written by Dorai Sitaram, adapted for Gambit-C.
- Meroon, an object-oriented extension to Scheme, written by Christian Queinnec and
modified to run well on Gambit-C.
- Beating the Averages by Paul Graham tells how to beat your competitors using Lisp.
He also wrote Revenge of the Nerds.
- Design Patterns in Dynamic Programming by Peter
Norvig explains why many of the classical design patterns used in C++ or Java are trivial or not needed in dynamic
languages like Common Lisp, Scheme, and Dylan, and presents new, more powerful, design patterns for dynamic languages. Later addition: Richard P. Gabriel, a strong proponent of design patterns
in computer programming, claims that the Gang of Four "Design Patterns" book
for C++ and Java programmers helps "losers lose less", and that design
patterns (lower case) are powerful techniques for organizing computer
programs, even in dynamic programming languages.
- A Common Lisp tutorial.
- Lawrence Lessig talks about how extensions to copyright terms over the last 40 years form theft from the public;
how software patents are holding back innovation; how small losses to copyright holders are leading to federal proposals of legal
vigilantism, where corporations are given free rein to hack your computer; and what you can do about it.
- An interesting essay about several things: the history of the computer gaming industry, the importance of computer
games in motivating learning about computers, and how open-sourcing computer games would
increase innovation and progress.
- There are blog aggregators for Lisp and Scheme.
- Why Lisp?
- Want to learn Scheme? Structure and Interpretation of Computer Programs is the best book on
programming ever written, and it uses Scheme, and it's available online. SICP is somewhat mathematical and moves at
a pretty fast clip; if you want a slower introduction to programming using
Scheme, I recommend The Schematics of Computation, which contains all the big ideas of SICP, but
uses a broader range of examples---I call it "SICP for mortals". Unfortunately, it's not available online but I think it's worth buying.
In a hurry? Try Teach Yourself Scheme in Fixnum Days by Dorai Sitaram.
Another text available online is How to Design Programs,
which is closely integrated with PLT Scheme.
Of the few French textbooks that I know, I like Programmer avec Scheme: De la pratique à la théorie, by Jacques Chazarain.
And, if you're looking for programming exercises that are not trivial
but not too involved, try the blog Programming Praxis, written by Phil Bewig. Learn visually? John Clements
has collected a list of Scheme video lectures and talks.
Scheme implementation is Gambit Scheme, written mainly by Marc Feeley.
- Want to learn Common Lisp, likely the most powerful Lisp dialect? The Land of Lisp
is a great book by Conrad Barski, M.D. He has a great sense of humor, writes well, and teaches Common Lisp
through game programming, a great way to learn anything! If you don't want to read the book, at least see the
music video! Update: There's now a review of The Land of Lisp on Slashdot. Another good book is Practical Common Lisp
by Peter Seibel. There are several free Common Lisp implementations,
you could start with SBCL.
What graduate students should do after qualifiers
Some, if not most, areas of mathematics require "intermediate-level" material before going on
to study recent papers and write a thesis. Here is my advice for students who think they may be interested in various fields. Other faculty members will have their own lists, I'm sure.
- Wavelets and image processing: Second course in real analysis (MA 545), functional analysis (MA 546 or 611).
Depending on your interests, Probability and Statistics (MA 538/539, Stat 567); Image Processing (ECE 637/641); Partial Differential Equations,
Convex Analysis, and Numerical Methods (MA 642/643, MA/CS 615, Brezis's Operateurs Maximaux Monotones et Semi-Groupes de Contractions dans
les Espaces de Hilbert)
- Numerical methods for partial differential equations: Second course in real analysis (MA 545), applied functional analysis (MA 611), partial differential equations (MA 642), CS 615 or the equivalent math
- Applied partial differential equations: Second course in real analysis (MA 545), applied functional analysis (MA 611), partial differential equations (MA 642).
- The West Lafayette campus of Purdue University has purchased a site license for the book Basic Concepts of Mathematics
by Elias Zakon, published by The Trillia Group,
an online publishing house I founded. This book helps the student complete the transition
from purely manipulative to rigorous mathematics while covering the following
topics: basic set theory, induction, quantifiers, properties of the real
numbers (including consequences of the completeness axiom), fields, and basic properties of n-dimensional
Euclidean spaces; the online index
gives more information about the contents. Under the terms of the site license,
this text can be used
without charge by any student or member of the faculty or staff of
the West Lafayette Campus of Purdue University.
Other schools buying site licenses for Basic Concepts of Mathematics include
the University of Windsor and
- The Trillia Group has also published the second book in
the Zakon Series on Mathematical Analysis, Zakon's
Mathematical Analysis I (which covers metric spaces, continuity, differentiation and integration; its index is online). The West Lafayette campus of
Purdue has bought a site license for this book, so any students or staff on that campus can download and use it for free.
The Trillia Group has licensed Proceedings.com to reprint Mathematical Analysis I
in paperback format for sale throughout the world. New: The Saylor Foundation has named Mathematical Analysis I one of the first winners of its Open Textbook Challenge.
- With the cooperation of William Moser, the Trillia Group has published
An Introduction to the Theory of Numbers by
- The Trillia Group has now released Mathematical Analysis II, which covers calculus on normed linear spaces, and (Lebesgue) measure and integration.
- There are many free books, sets of lecture notes, interactive courses, etc., that are of value for students learning mathematics;
I've put together a set of links to online mathematics materials that you may find of interest.
- I've been reading Maisonneuve magazine for a few years now. It's an english-language
journal out of Montreal. In my opinion it's smarter and sharper than, e.g., Harper's or the Atlantic Monthly.
- Recently I discovered Seed magazine, which deals with the intersection of science and culture.
Also out of Montreal, but this you can't really tell by
the content. Later addition: After a hiatus, back in print.
- Other magazines of interest include Adbusters (against corporatist culture),
Geist (overtly Canadian), and SubTerrain (raw, "urban", writing), all
out of Vancouver.
- Check out Cabinet, a "Quarterly of Art and Culture." It's fantastic. I presume it takes its
name from a Victorian "curiosity cabinet." Eclectic, everything is of interest.
- Finally, there's Granta, which has, on average, the best writing of any periodical. Often has
themed issues of particular interest.
My wife Maureen is an ATA-certified translator from French into English.
The government of Australia is paying Enviromission a billion Australian dollars
to build the "Solar Chimney",
a solar power plant that will provide enough power for 200,000 homes and will be the tallest structure in the world. Time Magazine chose this project
as one of its Best Inventions of 2002. Schlaich Bergermann und Partner is
the consulting engineering firm for the project; their description of their device can be found
here. From their web site, it appears they have been working on this technology since the early 80s---they built a prototype in Spain in 1981/82. Note: It's 2008, and Enviromission isn't any closer to building the tower.
My father, Robert Lucier, invented such a device in the mid 70s and patented it in several countries; the US
patent was first filed in 1975 and granted in
1981 (full text
here); the Australian patent application was filed in 1976 and granted
the Canadian patent was granted
in 1978; the Israeli patent application was filed in 1976 and
granted in 1979.
