are you able to clear up it? Do you might have the thoughts of an engineer? , arithmetic

For those who’ve ever taken a stroll alongside the Macclesfield Canal, you’ve got come throughout a ‘snake bridge’ just like the one above, with one aspect of the towpath rolling backwards.

Query is: Why did they construct such bridges?

At present’s challenges are reverse engineering image puzzles. You might be introduced with footage of 5 curious constructions, and your activity is to seek out out why they have been constructed that means. First cease, Cheshire.

1. Curly Crossing

The McClesfield Canal opened in 1831 and consists of a number of ‘snake bridges’, or ‘roving bridges’, the place the towpath passes in a loop from one aspect to the opposite, as proven above (and photographed on the prime of the story) ) Why have been they made that means? Take into consideration what the canals have been initially constructed for, and search for clues within the image.

I might be again within the UK at 5 pm. No spoilers please. As a substitute, please focus on your favourite examples of engineering ingenuity.

Replace: You possibly can learn the reply right here.

At present’s puzzles have been instructed by Nikolai Andreev, a Russian mathematician who final month gained the Lilavati Prize, an award given each 4 years by the Worldwide Mathematical Union, to “publicize about arithmetic as an mental self-discipline”. Excellent contribution and its vital position in elevating consciousness”. performs into numerous human endeavours. ,

Andreev was particularly appreciated for the free useful resource Mathematical Etudes, which has many fantastic movies explaining mathematical and mechanical phenomena. He additionally collaborates with Quantic, {a magazine} about math and physics aimed toward elementary faculty kids, and from which all the above photos are taken.

Due to Nikolai Andreev and Quantik for permission to make use of the photographs.
