PI Day 2025
Proving yet again how the NTHSA is up to any challenge, we rallied to host our rescheduled Pi Day on April 3rd, after a severe winter storm brought the City to a standstill on the original Pi Day in March. To maximize member participation across Canada, it was a hybrid event of virtual and in -person presentations.
This year’s Pi Day science lecture focused on the preliminary findings from our project funded by MITACS, the Calgary Tesla Society, the NTHSA and the Serbian Ministry of Foreign Affairs and carried out by a research team from the Athabasca University. These findings indicated an under-representation of Nikola Tesla both in science textbooks and for due credit for the tesla unit (T) named after him.
Dr. Farook Al- Shamali from Athabasca University opened the evening with a summary of his remarks at the 2025 AAPT Winter Meeting in St, Louis, Missouri, where he spoke about Nikola Tesla in Science Textbooks in the Canadian Education System with reference to these findings. He was followed by the featured virtual presentation by intern Matthew Yaguchi who conducted the primary data analysis for the project that made a case for the findings. Afterwards there was a lively question and answer period from the audience that was moderated by Dr. Angela Beltaos who was also one of the key supervisors of the project on the research team drawn from Athabasca University.
On a lighter note at the end of the program, Vice President Lydia Emanuel introduced several as yet unedited teaser videos submitted from Tesla enthusiasts across the world for the upcoming Tesla Tales Across the Globe production planned for Summer 2025.
Attendees then moved to the Pi-themed social portion of the evening, with pizzas, decorative Pi cookies created by the NTHSA’s Vice President, Lydia Emanuel, and a pie-tasting contest judged by Treasurer Robert Litschel and Vesna Srnic who awarded the prize for best pie to Dr. Elaine Beltaos-Kerr.
Informative and fun evening for everyone in attendance!
