The 3n+1 conjecture represents an intriguing mathematical problem, because it is simple and yet, it turns out to be unsolvable. In fact, its very existence is a challenge to all mathematicians because it appears to be both a complete waste of time and a beautiful pathway to humility at the same time. Generally known as the Collatz conjecture, it is also known as the Thwaites conjecture, the Kakutani’s problem, the Ulam conjecture, the Hasse’s algorithm, or the Syracuse problem.
