TED: Math is the hidden secret to understanding the world | Roger Antonsen

The video explores the concept of understanding, emphasizing the importance of changing perspectives. It delves into mathematics, highlighting patterns and representation as key elements. The speaker uses the number four-thirds to demonstrate how different perspectives can reveal new insights. The video concludes by linking understanding with empathy and encouraging viewers to adopt flexible perspectives.
