Researchers from McMaster University's LIVELab studied speed dating participants using motion capture technology and found that synchronized body sway between potential partners predicted interest in long-term relationships, even after controlling for physical attractiveness. The study suggests that body sway coupling reflects the quality of interpersonal communication and compatibility between partners.
A speed-dating event design problem explores how to arrange rounds so every participant meets everyone exactly once without repeatedly hearing the same introductions. The solution involves combinatorial mathematics, specifically resolvable Steiner designs, which require divisibility constraints and can be elegantly constructed using finite field geometry when table size is a prime power.
