Birthday - Alan Turing

Spare 6 min 32 sec of your time on or before June 23, Alan Turing's birthday to watch this clip about his explanation of the Entscheidungsproblem - The Halting or Decision Problem.

Brilliant mathematics by Alan Turing. Magnificent acting by Derek Jacobi as Alan Turing.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Ah, the first time someone realized that poorly written code could cycle endlessly, and there may be no way to prove that it won't do that.
