Can you truly grasp a million? A billion? A trillion? Our brains are wired for survival, not for comprehending vast scales. In this eye-opening TEDx talk, we’ll explore the fascinating intersection of mathematics and psychology - why humans struggle to imagine large numbers, how this impacts our decisions, and what it means for understanding global challenges. From the size of the universe to the scale of wealth and data, discover why the world is far bigger than we can ever truly perceive. Young psychologist, recent graduate of the University of Łódź, with a great passion for theories of mind, sports and philosophy, among other seemingly unrelated topics. The combination of these various interests allows him to look at the world in an interdisciplinary way, seeing connections where - at first glance - only separate phenomena are visible.Mathematics also holds an important place in his life, with its abstract concepts and relentless honesty, which applies to everyone regardless of human will. At TEDx University of Lodz, Bartek will present several counterintuitive mathematical concepts and their consequences for our perception of the world. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
