Welcome to one of the most fascinating areas of mathematics. There's a fair amount of work involved in understanding even approximately how the recent proof of this theorem was done, but if you like mathematics, you should find it very rewarding. Please let me know by email how you like these pages. I'll fix any errors, of course, and try to improve anything that is too unclear.

The word abacus comes from the Greek word "ABAX" meaning a calculating board or calculating table. It was invented by the Chinese, the first known record of the abacus was from an ancient sketch in a book from the Yuan Dynasty which was in the fourteenth century. It has a Mandarin name which is"Suan Pan" which means calculating plate. It's inventor is unknown. The Abacus is mostly referred to as the first computer

General Information
If you are looking for a fast, very good overview of the history of mathematics, then select Overview . Perhaps the most extensive archive for the history of mathematics is MacTutor at Saint Andrew's University in Scotland. This is the work of John O'Connor and Edmund F. Robertson of the School of Mathematical and Computational Sciences. The archive contains information on more than 1000 mathematicians, in two groups: long biographies (alphabetical index or chronological index) and short biographies index. There is a Chronology showing the overlapping lives of mathematicians in the long biographies. Further, there is a birthplace map, a mathematicians of the day page, and a list of anniversaries for the year. Finally (but not exhausting everything in MacTutor) is a list of other good sources of information available on the web concerning the history of mathematics. On the other hand, the most extensive as well as spectacular resource may be at Clark University. David E. has amassed a massive (ptp) amount of information. Just consider his Regions or Web Resources, to identify only two of his contributions. Further, by going to his Home Page page, you can access such things as regional mathematics, subjects, chronology, timelines (these are particularly fascinating), and books and other resources. Other web resources worthy of note are at the University of Utah.

Interest in and use of the World Wide Web has been expanding at a phenomenal rate. As the Web grows, so must its vehicle of communication, HTML. The HTML 2.0 specification is dated November, 1995. Since then, the HTML 3.0 draft specification expired on September 28, 1995, without becoming recommended, and HTML 3.2 became a W3C (World Wide Web Consortium) Recommendation on January 14, 1997. Now we have the public draft for HTML 4.0, announced on July 8, 1997. This draft is almost certain to undergo changes before being accepted by the W3C as a Proposed Recommendation--if it does, indeed, ever become a recommendation.

The ABACUS II, designed and built by Texas Instruments, was the first practical automated production machine for the assembly of integrated circuits. Using heat and pressure, it bonded fine gold wire to microscopic contacts on the silicon chip and pin connections on the package. The ABACUS II could maintain a positioning accuracy of ± 0.00025 inch while bonding up to 375 devices an hour. Following the success of this prototype, almost 1,000 ABACUS II wire bonders were built, making the economical mass production of integrated circuits a reality.

Heinrich Hertz - first to detect radio waves in 1887 by causing a spark to leap across a gap that generated electromagnetic waves - built oscillator and resonator by 1893
Oliver Lodge in Britain, Alexander Popov in Russia, Edward Brauley in France - filled a glass tube with metal filings that would cohere under electromagnetic waves and when the tube was tapped, the filings would collapse to break the circuit - built coherer to detect radio waves by 1894
