Part I - The Age of the Polymaths Includes the evolution of the calculating devices up to the invention of the Stepped Wheel by Leibniz. Part II - Crossing the 19th Century Discusses commercialized designs and abandoned designs, and the quest for a keyboard. Part III - Getting Ready for the 20th Century Reviews the development of office machines until the 1960's, when the first electronic calculators appeared on the market.

The international symposium provides an opportunity to learn of new developments and to present original research results in all areas of symbolic mathematical computation. Internet Accessible Mathematical Computation, a workshop at ISSAC 2003, will be held Thursday, August 7, 2003, at Drexel University. The workshop is free for all ISSAC '03 participants. http://www.SymbolicNet.org/conferences/iamc03 Topics of the workshop include, but are not limited to: - Remote access to mathematical software over the Internet - Encoding of mathematical expressions - Interoperability between software that create, transform or display mathematical expressions via ad hoc communication protocols and software architectures - Web-based mathematics education - Access and interoperability to mathematical knowledge bases - Protocols, APIs, URL schemes, metadata, and other mechanisms for system interoperability, parallel/distributed computing, and standardization - Application of IAMC for practical purposes For more information on IAMC, current and past activities, and proceedings of previous IAMC Workshops, please visit the IAMC Information Site: http://icm.mcs.kent.edu/research/iamc.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors Donations http://deptapp.drexel.edu/ia/GOL/giftsonline1_MF.asp _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ |
