David Henderson's Experiencing Geometry

Friday, September 22nd, 2023
11:00 am PT | 12:00 pm MT | 1:00 pm CT | 2:00 pm ET
Presenter: Dr. Daina Taimina

Summary:

The first edition of Experiencing Geometry was published in 1995. It was a result of Prof. Henderson’s 20-year experience of teaching geometry and honing his unique teaching style. While preparing 4th edition of this book in his memory, I went through his notes and journals from the 1970’s which gave me an insight into how deeply he was thinking about meaning in mathematics. I will share some of that and will talk about Prof. Henderson’s decision to switch from a highly regarded research mathematician’s path to “educational  mathematics” (his term).

Registration Closed

Duration: 60 minutes

Format: Online seminar via Zoom web meeting software with questions and discussion. Detailed instructions for joining the seminar will be emailed to registered participants.

Presenter:

Dr. Daina Taimina was born in Riga, Latvia, where she received all her formal education, including completing PhD in mathematics (1990) for the work in Theoretical Computer Science. For 20 years taught different mathematics courses at the University of Latvia, then for the next 20 years at Cornell University. Daina is best known for crocheted hyperbolic planes to use in teaching non-Euclidean geometry. She has written and co-authored several books in mathematics (in Latvian, Russian and English).  Her book for the general audience on exploring hyperbolic geometry through crochet – Crocheting Adventures with Hyperbolic Planes, AKPeters, 2009 won 2012 Euler Book Prize. In 2018 the second edition of the book was published by CRC Press and now is also available in paperback. The most recent book is 4th edition of Experiencing Geometry: Euclidean and non-Euclidean with History (with David Henderson) which is now open source : https://projecteuclid.org/eBooks/books-by-independent-authors/Experiencing-Geometry/toc/10.3792/euclid/9781429799850
