1/ Human beings have been stuck in the thinking of plane geometry for a long time. We are accustomed to the law of space - between two points, a straight line is the shortest. 2/ Even though we later realized that the world still has surface geometry, spatial laws still dominate. Just modified the path calculation method, but fundamentally, it is still the 'shortest space'. 3/ However, the deeper underlying law is not the law of space, but the law of time. Under the law of time, the optimal path is not the shortest spatial distance, but the least time-consuming. 4/ The propagation of light is an example: It does not take the shortest path in space, but rather the shortest path in time. This is Fermat's principle of minimum time. 5/ Modern physics goes further. Feynman's quantum historical path integration method is a universal law summarized based on the law of time. 6/ Life also follows the law of time. Schr ö dinger said: Life is a dissipative structure that feeds on negative entropy, Its existence depends on the irreversibility of time. 7/ In terms of engineering and product design, our innovation mostly stays at the level of spatial laws. Formalization, mechanization, reductionism... these are all products of spatial thinking. 8/ The true paradigm shift requires entering the world of time laws. 9/ Satoshi Nakamoto's Bitcoin is a typical example: A system operating in a dissipative structure with irreversibility over time, Realized decentralized consensus and global completeness. 10/ A system that follows the law of time reveals the underlying order of physics and information, It is also the largest source of innovation for humanity today.
