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

If you happen to’ve ever taken a stroll alongside the Macclesfield Canal, you’ve got come throughout a ‘snake bridge’ just like the one above, with one facet of the towpath rolling backwards.

Query is: Why did they construct such bridges?

Right this moment’s challenges are reverse engineering image puzzles. You might be offered with photos of 5 curious buildings, and your process is to search out out why they have been constructed that manner. 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 facet to the opposite, as proven above (and photographed on the high of the story) ) Why have been they made that manner?

Right this moment’s puzzles have been prompt 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 essential function in elevating consciousness”. performs into various 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 geared toward elementary college kids, and from which the entire above photos are taken.

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