A fish is swimming inside a rectangular tank that measures two metres in height, one metre in width, and one metre in depth. The puzzle provides three different views of the path the fish took: one from the front, one from the right side, and one from the top. The challenge for readers is to determine and draw the top view of the shortest path the fish could have taken that would match the front and side views shown. These puzzles were created by George Watkins, a mathematics educator, to mark the opening of the 1729 Maths School in Mill Hill, north London. The school is set to welcome its first students later this month and is the first specialist mathematics secondary school in the United Kingdom. The name “1729” refers to a famous story involving the mathematician Srinivasa Ramanujan, who noted that 1729 is the smallest number that can be expressed as the sum of two cubes in two different ways. This number became known as the “Hardy-Ramanujan number” after a conversation between Ramanujan and mathematician G.H. Hardy. The puzzles are part of a regular feature that has appeared on alternate Mondays since 2015. The feature invites readers to submit their own puzzles for potential publication, encouraging a community of puzzle enthusiasts and math lovers. This particular puzzle serves both as an educational tool and a celebration of the new school’s mission to inspire and challenge students in the field of mathematics. George Watkins, through his puzzles, aims to make mathematics engaging and accessible, using creative and visual challenges to spark interest in the subject. The 1729 Maths School hopes to build on this spirit by offering a focused and innovative approach to math education, preparing students for future academic and professional challenges in STEM fields.
