First MathML Conference Signifies Coming of Age: Finally the Web Does Math
October 30, 2000

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. 

MathML is the standard endorsed by the World Wide Web Consortium (W3C) for representing mathematical notation on the web. It was a proposal from Wolfram Research to the W3C that first began the MathML initiative. Many of the key concepts used in MathML are based on concepts originally developed in Mathematica, which fully supports MathML. 

MathML is an XML application that fills the need for an efficient means of presenting mathematical or technical expressions on the web. Previously, such expressions had to be "frozen" in an image format such as a GIFa static and cumbersome methodand inserted into an HTML document. The MathML standard makes math on the web a living, easily adaptable, and reusable entity, and it is now seen as being integral to the creation of new e-business and online educational opportunities. 

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 MathML.

More information about the MathML conference, including presentation abstracts and an update on the availability of conference proceedings, is at www.mathmlconference.org


Mathematica Fashion Comes to Japan
September 29, 2000

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 useimages of knot theory and Escher patterns.

Wolfram Research's Alan Skillman and staff attended a premiere showing of the Mathematica-inspired designs. After the show, a JIPS representative gave a demonstration of how Matsui used Mathematica in fashion design.

Matsui's clients include Hikaru Nishida, a well-known Japanese singer. The singer gave a live performance shown on major Japanese television stations wearing one of Matsui's Mathematica creations.

The new designer's collection has attracted much attention and requests for information. Interviews with Matsui were published in many Japanese publications. Matsui's use of Mathematica has established her as an exciting new talent in her field.

Math Olympics and Mathcamp
November 2000

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 "CryptographyA 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.

"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." 

"6 Integers" can be downloaded as a stereo MP3 file. To read more about Carl McTague, visit his web site at www.mctague.org/carl.
