Another famous question of Hopf is the Hopf product conjecture: Can the 4-manifold carry a metric with positive curvature? The conjecture was popularized in the book of Gromoll, Klingenberg and Meyer from 1968, and was prominently displayed as Problem 1 in Yau's list of problems. Shing-Tung Yau formulated there an interesting new observation (which could be reformulated as a conjecture). examples of unforced errors in tennis
