London's Iconic Cab: A Puzzle Legacy That Rode into History
In 1729, mathematicians discovered that the year was a "taxicab number", where each digit can be used as a sum of its own digits in multiple ways. This curious phenomenon has spawned a series of puzzles that have been delighting solvers for decades.
One such puzzle asks for the smallest number that can be expressed as the sum of two squares in two different ways. The answer, 50, is achieved by combining 1^2 + 7^2 and 5^2 + 5^2.
Woodworkers, meanwhile, have been challenged to arrange strips of wood with lengths 1, 2, 7, 17, and 29 centimeters in a way that prevents three strips from forming a triangle. The solution lies in the length of the additional strip, which can be any of five values: 3, 4, or 5.
Lastly, math enthusiasts are asked to consider four numbers (a, b, c, d) and six possible multiplications between them. By applying logical reasoning, solvers will discover that the sixth product is 2 x 6 = 12.
These puzzles have stood the test of time, evoking a sense of nostalgia for a bygone era. The iconic London cab, with its historic significance and enduring popularity, has become an unlikely muse for mathematicians and puzzle enthusiasts alike.
