EXECUTIVE SUMMARY: Professor Lesser has several articles on connections between Judaism and math/statistics. His journey has spanned nearly every stream of Judaism, giving him a foundation to connect with the diverse Jewish and mixed audiences at talks/concerts. He co-organizes an international funded 2021 speaker series on math-and-religion (for which he gave the opening talk) and is a Hadar 2021 Jewish Wisdom Fellow.
An award-winning Professor at The University of Texas at El Paso (same 31.76oN latitude as Jerusalem!), Dr. Lesser conducts research in statistics/mathematics education. He was listed as a supporting faculty member throughout the existence (2005-2018) of the UTEP Inter-American Jewish Studies Program and several of his 120 scholarly papers connect math/statistics with Judaism. This led to being the lead scientist and co-grantwriter for Temple Mount Sinai’s competitively-selected proposal to present local and international speakers in the 2021 series “Higher Meanings: Exploring Connections Between Religion and Mathematics“, as part of the national Scientists in Synagogues program funded by Sinai and Synapses (supported by CLAL-The National Jewish Center for Learning and Leadership, the John Templeton Foundation, and individual donors, in consultation with the DoSER program of the American Association for the Advancement of Science, the world’s largest scientific society). Lesser gave the opening presentation (on infinity, viewable here or here) for this series, which has generated coverage from TV (e.g., ABC-affiliate KVIA), radio (e.g., NPR station KTEP-FM), and print media (e.g., Jewish Herald-Voice), and moderated the subsequent presentations (e.g., this, this, and this).
In May 2006, he published in Journal of Mathematics and Culture (JMC) the first juried comprehensive education-oriented article on Jewish mathematics, based on his years creating curriculum integration as a full-time mathematics teacher at a pluralistic community Jewish high school. The article offers scholarly background and diverse classroom-tested examples of not just the obvious area of gematria, but also quotations, mathematical firsts, counting (permutations, marking time, etc.), infinity, pi, mathematical modeling, geometry, logic, and connections to Jewish text/customs. These enhancements connected to school culture/activities and appeared to help motivate some students towards broader view and deeper engagement. Lesser published a followup paper (with a randomized experiment) in Journal of Mathematics and Culture as well as a short Pi Day piece in The Jewish Educator. His JMC papers also appeared in the book Culture that Counts. Also, Lesser explored language/culture parallels between math education and Judaism in a 2015 paper in Teaching for Excellence and Equity in Mathematics and contributed to the 2015 ethics module Integrating Ethics from Thought to Action commissioned by the Texas Holocaust and Genocide Commission.
As mentioned above, Lesser co-organizes an international funded 2021 speaker series on math-and-religion (for which he gave the opening talk). Lesser makes material engaging and accessible for audiences of varied (religious or mathematical) backgrounds. (He has also given presentations for the UTEP Religious Studies program on his educational Jewish songs based on Talmud, Torah, Midrash, and culture: his album SPARKS was a Finalist for Best Album in the 2021 New Mexico Music Awards and its approach yielded articles in NewCAJE The Jewish Educator and The Israeli Journal of Humor Research) These experiences led to his being named (one of 46 from well over 200 applications) a Hadar 2021 Jewish Wisdom Fellow.
Since 1997, Lesser has used his award-winning pedagogical skills to give (for varied multi-congregational settings, audiences, and formats) engaging interactive math-and-Judaism presentations for the International ALEPH Kallah, citywide Yom Limmud or Tikkun Leil Shavuot events (e.g., Houston, El Paso), individual congregations (from Modern Orthodox to post-denominational; for example, here), pluralistic day schools or Sunday schools (e.g., Ft. Collins, El Paso, Houston, Albuquerque, Austin). Talks have included: “How We Count” (how Jewish values are embedded in the very way Jews mark time, count in holy texts, and count themselves), “Lots and Lotteries” (Jewish texts and views on chance — from ancient to modern), and “Who is Wise?” (secular and Jewish perspectives on wisdom). After a talk at El Paso’s Temple Mount SInai, Rabbi Ben Zeidman wrote: “His talk was both meaningful and accessible. All who were present had an uplifting and thought-provoking opportunity to learn. And on top of that, we all laughed with Dr. Lesser a great deal.”
