Previous Update: May 15, 2022. (Thanks to Eve A. Stone)

Added June 23, 2020: Thanks to the efforts of Gadi Aleksandrowicz, the archives of the Heberew periodical "Gilyonot le-matematika", for "high school students and amateurs" (edited, for many years, by my mentor, Joe Gillis z"l), and its successors, Etgar, and most recently, Net-gar (edited by my good friend Ron Aharoni yla"a), are back here, until they find a more permaent place. I believe that this is very improtant, not only mathematically, but historically. Thanks Gadi!

Added July 12, 2023: Unforunately, the archive to gilyonot is currently not "open access", but Professor Anat Yarden, current chair of the Department of Science Education at the Weizmann Institute of Science, kindly pointed out that volume 1 is free access. I really hope that Gadi Aleksandrowicz will be able to restore everything.

    Added June 23, 2017: I LOVE David Wilding's great Clear the Deck website, that lets you generate intriguing integer sequences by clearing a deck of cards by any rule you make up.



    I am also honored and pleased to have been on the International Advisory Board of Thales+Friends.
    I love to brouse in Eric's Treasure Troves , Eric Weisstein's monumental feat, that contained a lot of fascinating mathematics, including entries on `Wilf-Zeilberger pair' , `Zeilberger algorithm', and the Alternating Sign Matrix Conjecture.

    Eric also has very illuminating bios of notable scientists, like Pythagoras, Archimedes, Newton, Einstein, and Zeilberger , among others.

    Jon Borwein's memorial page
    Added Aug. 4, 2016: Jon Borwein, sadly, died on Aug. 1, 2016; Let's hope that his great website will live for ever.

    Equally revolutionary, birthplace of SPECIES (the most fruitful unifying concept in enumerative combinatorics of this quarter-century), is LACIM that has links to the masters Francois Bergeron, Pierre Leroux, Gilbert and Jacque Labelle, Christophe Reutenauer, and the one-and-only Simon Plouffe.
