PRIZES AND NEXT VENUE
18:1518:45  (closing slides) The David Hestenes Promising Young Researcher Award was awarded to two new talents: • Jorge Ventura for his presentation "Applications of Geometric Algebra in Surveying and Geometry" • Daren Thimm for his presentation "Factorization of the Conformal Villarceau Motion".
 
Next Venue: ACACSE 2026 will be in Beijing, Chine at the begining or end of Summer. Hongbo Li will set up the organization. (We are thus leaving the 3year schedule alternating with ICCA, but will not overlap with ICCA 2026 in time.)
