You and your noted mathematician colleagues convene in (virtual) Geneva to present brilliant theories pertaining to one of the world’s great mysteries, the elusive 3n Problem.
The 3N problem offers a fantastic world of exploration for learners of all ages. (I have done this with kids as young as the third grade.)
The problem is known by several other names, including: Ulam’s problem, the Hailstone problem, the Syracuse problem, Kakutani’s problem, Hasse’s algorithm, Thwaite’s Conjecture 3X+1 Mapping and the Collatz problem.
The 3N problem has a simple set of rules. Put a positive integer (1, 2, 3, etc…) in a “machine.” If the number is even, cut in half – if it is odd, multiply it by 3 and add 1. Then put the resulting value back through the machine. For example, 5 becomes 16, 16 becomes 8, becomes 4, 4 becomes 2, 2 becomes 1, and 1 becomes 4. Mathematicians have observed that any number placed into the machine will eventually be reduced to a repeating pattern of 4…2…1…
This observation has yet to be proven since only a few billion integers have been tested. The 4…2…1… pattern therefore remains a conjecture.
