Solve hard problems in your own scientific field, build the reference solution in Python, and judge whether an AI's answer is actually correct, catching the wrong assumption or missing constraint rather than just the wrong number. Seven fields qualify, and no specific degree or number of years is required. Global, roughly 15 hours a week.
