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”
Free Effect . A new ice cream company in India has set up free ice cream vending machines on the streets to promote its brand. Result? People lined up at a very long distance in front of the vending machine. It was raining then, and the people in line went to a convenience store to buy umbrellas, then lined up again. Umbrellas cost much more than ice cream . However, people kept lining up. Cheap and free are two completely different concepts . When the price is low, sales increase slightly, but when it is free, an extraordinary dimension of the problem arises. It’s a privilege , so consumers are willing to pay a higher price to get something for free. Free is not a matter of reason; it is a matter of emotion . - Joseph’s “just my thoughts”
