The London Cab that Rode into History: A Trio of Puzzles from 1729
In 1729, a peculiar year often referred to as "taxicab number" due to its unique properties related to the number of London cabs on the road at any given time, three puzzles were posed by a clever puzzle enthusiast. These puzzles, now shared with us, showcase the ingenuity and creativity of mathematical thinking.
The first puzzle, known as "Square Pair," asks for the smallest number that can be expressed as the sum of two squares in more than one way. After some careful consideration, the solution reveals itself to be 50, which can be represented by the equation 1^2 + 7^2 = 5^2 + 5^2.
Moving on to "Strip Tease," we are presented with five strips of wood of varying lengths: 1 cm, 2 cm, 7 cm, 17 cm, and 29 cm. The goal is to add a sixth strip of maximum length 29 cm, ensuring that it remains impossible to form a triangle using any three strips. After analyzing the given lengths, we find that the possible lengths for the seventh strip are 3, 4, and 5 centimeters.
The final puzzle, "Sick Sixth," involves four numbers: a, b, c, and d. Given six ways to multiply two of these numbers together, we need to determine the value of the sixth product. By cleverly analyzing the possible products, we arrive at the solution that the sixth product is 2.4.
These puzzles not only showcase mathematical ingenuity but also demonstrate the importance of creative thinking in problem-solving. Whether you're a seasoned math enthusiast or just starting out, these puzzles are sure to challenge and entertain. So, grab your calculator and get ready to ride into history with the London cab that roams into our minds!
