One of the most mind-bending segments of the course introduces students to Cantor’s theory of transfinite numbers. Students learn that not all infinities are the same size. Through diagonal arguments, 18.090 demonstrates that the infinity of the real numbers is strictly larger than the infinity of the integers, fundamentally shifting how students view the mathematical universe. Why 18.090 is Critical for STEM Students To give you a taste, here is a typical 18
