The Isochronic map

Stories from Physics for 11-14 14-16 IOP RESOURCES

In 1883, Francis Galton, Charles Darwin’s cousin, developed an ‘Isochronic Passage Chart for Travellers’ which indicated, by coloured shading, the time it would take a traveller starting in London to travel to different parts of the world. To reach the farthest areas of the map, including parts of Australia and New Zealand, would have taken 40 days of travel. Recently, a travel company produced an updated version of the map for journeys in 2016. The maximum travel time on the modern map is just a little over one and a half days.
