Chapter 1 EXPLAINING THE VERY IMPROBABLE
The author mainly explains the complexity of various things from the perspective of physics and biology. Complexity is the result of stacking out a variety of simple things with randomness or a certain probability. But natural still life, the complexity of biological and man-made designs are different. The author then further explained the mechanism of biological complexity.
Chapter 2: GOOD DESIGN
The author introduces the complex mechanisms of different types of bats to establish night vision through different echo acoustic systems, different echo response mechanisms for static and dynamic objects, and how humans can adjust and change the radar system design based on this mechanism. process. This defines what is a good design from a biological perspective.
