Eyes Down

This new feature will be a regular picture-based item that you might use with your pupils, or your department, or just by yourself, to make you think about something in a different way

Train tracks at Geneva station

This picture was taken at Geneva railway station – yes, it’s a holiday snap! Do you ever hear yourself saying “parallel, like train tracks”? There are lots of sets of parallel lines in this picture, but if you start to look into the distance, the train tracks, whilst remaining the same distance apart and never crossing, also start to curve as the rails go around a corner. Does “parallel” only apply to lines? Can curves be parallel? Are concentric circles parallel? If these train tracks continued dead straight for a very long distance, what would happen? Would that still count as their being parallel? And once you’re thinking about spherical geometry, what, on the map, appears to be the shortest route between Heathrow Airport and Shanghai Pudong International Airport, and what, on a globe, is?

If you have a thought-inducing picture, please send a copy (ideally, about 1-2Mb), and a short (150 words maximum) commentary, to us at info@ncetm.org.uk - we look forward to hearing from you!

Love this. I often use a photo as a starter and ask the students what might todays topic be based on the picture. It often brings up all sorts of things I never considered.
