Think quickly: Which city is further west, Glasgow, Scotland or Madrid, Spain?
If you’re a cynic like me you’d guess Madrid. Of course, you’d figure it was a trick question whether you “knew” the answer or not. You’d also be wrong. Glasgow is indeed further west than Madrid.
However, if I substituted Edinburgh, Scotland for Glasgow, then you’d be correct. Indeed, Madrid is further west than Edinburgh. In fact, some portions of Spain are further west than the entirety of Scotland.
Counterintuitiveness
I love questions that toy with conventional wisdom. Sometimes we’re conditioned to think of direction – in this case “west” – in a nonlinear manner. The British Islands and the Republic of Ireland lay off the western coast of continental Europe. They observe a time zone that starts an hour earlier than their nearby neighbors, Spain, France and the Low Countries. This tricks the mind into thinking it that has to be further west than the rest of Europe. Nonetheless, place it on a map and the illusion disappears immediately. This happens much like the Reno/Los Angeles situation I featured some time ago.
Continental Europe extends appreciably westward as it forms the Iberian Peninsula and separates the Mediterranean Sea from the Atlantic Ocean. The latitude of the westernmost point in continental Europe, Cabo da Roca in Portugal, is further west than all of Great Britain and nearly the entirety of the Republic of Ireland to boot. Galway, Limerick and Cork are all to the east. Dublin is even further away.
My Current State of Mind
Intellectually I knew this peculiarity existed but I never thought of it much until recently. Recently I’ve been geo-coding mounds of coordinates on both sides of the Prime Meridian. I’ve been been designing a project in the background for the last couple of months. I’ll reveal it soon enough. More to the point, the software I’m using represents longitude as a negative number west of the Prime Meridian and a positive number to the east. So I’ve been barraged with constant reminders of where the coordinates fall. That led me to dig a tiny bit deeper and resulted in the curious little exercise I decided to feature today.
