Just for fun and for community participation, I offer the following riddle. The person who answers first (with complete explanation of how the answer is deduced) wins a free copy of Understanding Our Unseen Reality: Solving Quantum Riddles. Question: Susie and Paula's teacher gives Susie the sum of two numbers. The teacher gives Paula the product of the same two numbers. Both numbers are greater than or equal to 2. While trying to determine the two numbers, Susie and Paula have the following conversation: Susie: Paula, I don't know what the numbers are. Paula: I knew you didn't know, but neither do I. Susie: In that case, I know the numbers! What are the numbers?
