Explore the boundaries of human knowledge in this thought-provoking Oxford Mathematics Public Lecture by Marcus du Sautoy. Delve into the fundamental questions that have challenged humanity, from the origins of the universe to the nature of consciousness. Examine the limits of scientific discovery and mathematical prediction, questioning whether there are aspects of our physical world that lie beyond human comprehension. Investigate the complexities of quantum mechanics, chaos theory, and the uncertainty principle, while also pondering the enigma of consciousness and the potential limitations of the human brain in understanding itself. Through a journey that touches on religion, philosophy, and cutting-edge science, gain insights into what we can and cannot know about our universe and our place within it.
