Optimization: Adjusting something to reach its best state for a specific purpose. We often think that the fastest and strongest options are the best. The fastest way down a slope isn’t a straight line, but a parabola that naturally connects high and low points. A sniper can cause more lethal wounds at 400 meters than at 200 meters. Although the bullet travels faster at 200 meters, the wound size isn’t as large, and at 400 meters, the slower-moving bullet over a longer distance causes more friction as it passes through the wound, resulting in more severe injuries. In every situation, there is an optimal choice suited to the goal. Trial and error are useful for finding this optimization. - Joseph’s “just my thoughts”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
