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.

The king asked again. “Then who is the richest?” Bian Que also answered. “My big brother heals the disease without a...
