About
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.
A hot air balloon journey
An insight into the planning that goes into a hot air balloon journey and also how maps can be produced through filming from a hot air balloon.
Spherical geometry
This track shows us how a hot air balloon is produced and how the application of spherical geometry is imperative when planning a round the world flig...
Looking for Theta
Through a complex example, we learn how journeys are measured when the points are not on the equator and how this is calculated using Theta.
Great-circle distance
Great-circle distances might be the shortest way to travel, but they are not always the easiest. We also look at how lines of latitude aren't great-ci...
