Spherical geometry

Hot air balloon rides have become a popular celebration treat. But do they really just drift with the wind? Investigate the meticulous planning needed for round-the-world flights. Learn how journeys are monitored and measured, and discover how pilots merge mathematics and geography while high above the ground. This material forms part of the course MU120 Open mathematics.
