Nancy Blachman Chair, G4G Board of Directors | Founder, Julia Robinson Mathematics Festival In high school, Nancy was extremely fortunate to take George Polya’s short course in mathematical logic and to do a research project on continued fractions, both of which made her aware that it was more fun to learn by discovery than to be told how to solve problems and just to apply a formula. She enjoyed most of her math classes in college but she found Concrete Mathematics, taught by Donald Knuth, far more intriguing than all of the other math courses. To inspire students to explore the richness and beauty of mathematics through activities that encourage collaborative, creative problem-solving, Nancy founded the Julia Robinson Mathematics Festival, which is described in the Huffington Post article and on the Julia Robinson Mathematics Festival website. Yossi Elran Director of the Technology in Education Unit, Weizmann Institute of Science Yossi Elran is a theoretical chemist, recreational math enthusiast and puzzle collector. He works at he Davidson Institute of Science Education, the educational wing of the Weizmann Institute of Science in Israel, currently heading the Unit for Technology in Education and Distant Learning Activities. After several years of post doctoral research in the field of quantum mechanics, he decided to put his efforts into promoting science and math education and critical thinking for all ages, incorporating state-of-the-art internet technology and pedagogy. Yossi authors and runs the Institutes’s recreational math and popular science massive online courses for kids: Math-by-Mail and Science-by-Mail, and regularly lectures and runs workshops for students, teachers and the general public. He also coordinates the Israeli G4G activities in honor of Martin Gardner, including the national recreational math, puzzles and games conference and the celebration of mind events. In the past, he wrote a monthly recreation math column for several years in the Hebrew popular science journal, Galileo. His non-mathematical time is dedicated to running an organization that helps underprivileged children with special needs. Chaim Goodman-Strauss Geometer, Artist, Expositor, Teacher Mathematician and artist Chaim Goodman-Strauss co-authored the book The Symmetries of Things (A K Peters/CRC Press, 2008) with Conway and Burgiel. He produces large scale sculptures based on his mathematical interest in form (and is happy to take commissions). Goodman-Strauss has long engaged in mathematical outreach to the broader community, beginning the Saturday Morning Math Group (still continuing, at UT), producing the Math Factor podcast and radio segment. His graphic work can be seen at mathbun.com. Stan Isaacs Computer Programmer & Teacher A computer programmer, Stan retired from Hewlett Packard in 2002. He teaches in UNIX/Linux class locally. Also, in his spare time, he teaches vintage dancing (which is social dancing from the early 20th century and the 19th century) and folk dancing. He plays at mathematics (which was Isaacs’ major in college), and collect mechanical puzzles of all types. Isaacs collects books of Lewis Carroll (Alice in Wonderland and more.) Belinda Keir Freelance Writer and Former K-12 Teacher Belinda Keir is a freelance writer and former K-12 teacher living in Sydney, Australia. She first encountered Martin Gardner in a book in her high school library and has enjoyed the ‘fun’ side of mathematics ever since.
