Notă biografică
Scott Sherman is a leading software designer focused on building tools for seeing and understanding information, from computer-aided-design to diagramming to data visualization. He was a researcher and software engineering architect at Tableau, a data visualization company, where he built the first version of many essential tools including dashboards and highlighting. At Microsoft, he designed and built the layout engine for Microsoft Office’s SmartArt feature. Scott has been fascinated with flexagons since he first learned about them from Martin Gardner’s writings and has figured out techniques for generating a huge variety of new flexagons and flexes. He has also applied his software skills to create programs for exploring flexagon dynamics. He has given talks on various topics in recreational mathematics, including flexagon theory, at the Gathering for Gardner and Georgia Southern University. With Dr. Elran and Ann Schwartz, he co-led the 2019 Neil Shore Flexagon Workshop at the Davidson Institute, the educational arm of the Weizmann Institute of Science in Rehovot, Israel. He also is the author of an online, interactive book called Explorable Flexagons.
Yossi Elran is a British-Israeli recreational mathematician at the Davidson Institute of Science Education, the educational arm of the Weizmann Institute of Science in Rehovot, Israel, and teaches various courses at the Western Galilee College in Israel. He holds a PhD in theoretical quantum chemistry and has done post-doctoral research on decoherence, one of the main challenges of quantum computing. Yossi frequently journeys nationally and globally, delivering engaging and captivating presentations to diverse audiences ranging from schools and universities to festivals and other events on various subjects, including recreational math, astronomy, quantum mechanics, the history and philosophy of science, and creativity. He has written many papers, is the author of Lewis Carroll’s Cats and Rats and Other Puzzles with Interesting Tails, and Archimedes’ Stomach and Other Puzzles You’ll Love to Digest, and co-author of The Paper Puzzle Book. He is the creator of four popular "Future Learn" MOOC’s on recreational math, two of them on flexagons, and two Ted-Ed puzzle videos that have reached nearly 20 million views. Yossi is a longtime member of the Gathering 4 Gardner Foundation, whose mission is to stimulate curiosity and the playful exchange of ideas and critical thinking in recreational math, magic, science, literature, and puzzles to preserve and extend the legacy of writer and polymath Martin Gardner.
Ann Schwartz has created more than a dozen new flexagons. She has presented a new flexagon at the biennial Gathering for Gardner, which she has attended since 2006, and has given flexagon presentations and workshops at the National Museum of Mathematics (MOMATH) in New York City and that museum’s MOVES conferences. In 2015 she was the guest speaker at the Recreational Math, Puzzles and Games Conference at the Davidson Institute of Science Education, the educational arm of the Weizmann Institute of Science in Rehovot, Israel; and in 2017 gave the only flexagon presentation at the Seventh International Meeting on Origami in Science, Mathematics and Education (7OSME) in Oxford. With Scott Sherman and Dr. Yossi Elran, Ann co-led the Neil Shore Flexagon Workshop at the Davidson Institute in 2019. She coauthored "The Hexa-Dodeca-Flexagon," a chapter in Homage to a Pied Puzzler (2009), and the chapter "Should We Call Them Flexa-Bands?" that was published in The Mathematics of Various Entertaining Subjects - Volume 3.
