Mathematica Notebooks Now Accepted by arXiv.org
arXiv.org, the e-print server hosted by Los Alamos National Laboratory, now accepts Mathematica notebook submissions. Authors can submit notebooks as supplemental materials or as an entire article.
arXiv.org is an electronic archive and distribution server for research papers. Physics and related disciplines, mathematics, nonlinear sciences, computational linguistics, and neuroscience are part of what the fully automated archive contains. In the year 2000, an estimated 13 million preprints were downloaded from arXiv and its mirror sites.

First MathML Conference Signifies Coming of Age: Finally the Web Does Math
Nearly two hundred leading mathematicians, scientists, and web technology experts converged on Champaign, Illinois, for
the first "MathML and Math on the Web" conference, hosted by Wolfram Research, Inc.
IBM, a conference cosponsor, chose this event to announce the release of techexplorer 3.0, a web browser plug-in for Netscape Navigator and Internet
Explorer for rendering MathML. A technology exchange between IBM and Wolfram Research also provides techexplorer users a unique level of
interoperability with Mathematica, uniting web-based typesetting and technical computation. Several other major browser developers, such as
Microsoft, Netscape, and the W3C, also presented conference talks and product demonstrations that showed their commitment to supporting
Mathematica Fashion Comes to Japan
Eri Matsui, a newcomer to fashion design in Japan, used a unique approach in creating her Fall 2000 designs.
The one-time Chicago resident was inspired
by Mathematica images created by Wolfram Research's Michael Trott. Trott
was not aware of Ms. Matsui's use of Mathematica in her designs until
contacted by Japanese Information Processing Service, or JIPS, a Mathematica reseller in Japan. He then gladly supplied
new images especially for Matsui's use–images of knot theory and Escher
Math Olympics and Mathcamp
Every year Wolfram Research participates in educational and technological events for high school students. As cosponsor of this year's International Mathematical Olympiad (IMO) and Mathcamp 2000, Wolfram Research helped to send students from the international, national and local level to these events. Eight finalists from all over the U.S. and participants from 70 countries attended IMO.
To be selected for the U.S. Math Olympics team, students must complete a sequence of three exams. The eight top-scorers out of a total of 350,000 are invited to the Olympiad Awards Ceremony in Washington, D.C. Activities associated with the awards ceremony allow the U.S. team to meet some of the nation's best scientists and mathematicians.
After the awards, the U.S. team and 16 other finalists participate in an intensive month-long Mathematical Olympiad Summer Program (MOSP). The IMO competition follows the MOSP. Next year, Wolfram Research will be a major sponsor of the IMO, to be held in Seoul, Korea.
To be selected for the five-week Mathcamp 2000 program, students completed a challenging 10-problem test. The program's goal is to give students an opportunity to be creative in their thinking about advanced mathematical concepts. Participants also had a chance to make new friends and study with the great mathematicians of today.

Mathematica and the Science of Secrecy
"I have no doubt that I am not a genius," says Sarah Flannery, who considers herself to be a fairly regular girl with a wide range of hobbies and interests. Yet, in January of 1999, Sarah was named the Irish Young Scientist of the Year for her work in devising a highly innovative, fast, and secure new algorithm for data encryption of internet and other electronic communications. Sarah was asked to write about her experiences. The resulting book, In Code: A Mathematical Journey, was published in April 2000.
Sarah's project, entitled "Cryptography–A New Algorithm versus the RSA," was widely praised for its brilliant applications of number theory and its demonstration of a strong grasp of the fundamentals of cryptography. Along the way, however, she also discovered how "wonderfully powerful" Mathematica is. It was "great fun learning the Mathematica commands to [encipher and decipher]...just seeing it work was a real kick," she wrote.
Sarah set herself to the task of learning basic matrix theory in order to construct her new algorithm, writing programs to generate examples of unfamiliar concepts, and consulting her father and numerous journals for additional information. As her mathematics knowledge and programming skills increased, she was determined to write cleaner, more sophisticated code after admiring the work of others that demonstrated the "wonderful flexibility of the Mathematica language."
Using Mathematica, Sarah implemented both the RSA and the CP algorithms and performed comparative run-time analyses on them. Her efforts were rewarded when she was able to demonstrate successfully that the CP algorithm was 20 to 30 times faster than the RSA and to knowledgeably defend an attack on it as well.
An in-depth mathematical description and comparison of the RSA and CP algorithms, including the Mathematica code, is available at www.cayley-purser.ie. Sarah's story, In Code: A Mathematical Journey, is currently for sale throughout the UK, and can be ordered online through the Amazon.co.uk bookstore.
Mathematica Site Administrator Web Site Resource
Wolfram Research, makers of Mathematica, has announced the new Site Administrator web site (site.wolfram.com), an online resource to help Mathematica Site Administrators make effective use of their Mathematica license program. The site includes distribution information, installation instructions for all Mathematica platforms and configurations, links to information about Mathematica products and services, the answers to Frequently Asked Questions, as well as additional Mathematica resources and contact information.
"6 Integers": Making Music with Mathematica
On January 25, 2000, concert goers at the University of Cincinnati (UC) College Conservatory of Music heard the world premiere of "6 Integers," a Mathematica-generated musical composition by Carl McTague, a freshman at UC. Computed with Mathematica and rendered using a synthesizer playing piano and marimbas, "6 Integers" premiered to warm applause and positive responses.
The piece "6 Integers," as created by McTague, is an expression in Mathematica, just as "x2+1+p(x)" is an expression. Over the course of the composition, a single, coherent process explores six integers by means of 5,292 notes and four independent channels of audio. It is the first full piece generated by the Hierarchical Functional Inheritance Model (HFIM).
The HFIM is the basis of the "very promising mathematically-driven approach to composition" that McTague has been working on for several years now, says Mara Helmuth, director of the UC Center for Computer Music studio.
"Eventually, I realized that the digital computer could be of immense use in my work," he said. McTague, who has been using Mathematica for three years now, says he chose to do his musical work in Mathematica because "I think in mathematical terms and Mathematica lets me implement my ideas in mathematical terms."
In the case of "6 Integers," Mathematica evaluated the composition's "expression" to generate a tremendous hierarchical structure, which it then symbolically "flattened" to produce a list of explicit instructions with each command representing a note. A Perl script then translated these instructions into a binary format understood by synthesizers.
Says Helmuth, "One of the wonderful things about algorithmic composition is that it can allow people to experience mathematical and scientific ideas in the realm of the arts and senses, increasing modes of understanding for the non-scientist."
Mathematica in Economics and Finance
Increasingly, Mathematica is being used in the fields of economics and finance. The updated web site at www.wolfram.com/solutions/finance/ now includes information about software developed by Vanderbilt University Professors Philip Crooke, Luke Froeb, and Steven Tschantz and Justice Department Research Director Gregory Werden. This software aids antitrust enforcement agencies to use Mathematica to simulate the effects of horizontal mergers.
