黄峥致拼多多股东信：新的世界正在到来新的物种必然出现(9)

However， when an almost invisible virus awoken us to the reality that we are not above the world， but just a negligible part of the world to be observed， the only thing we can do is to sit still and let time carry its course． We then realize time is not really a parameter in an equation， but an irreversible vector． It is a silent and relentless directional force driving everything we see and feel． It effortlessly creates asymmetry， irreversibility and mortality， no matter how stubbornly and desperately we yearn for symmetry and immortality．
While the first law of thermodynamics （？U = Q-W） gives us a sense of control and certainty， the second law （？S ≥ 0） humbles us to acknowledge the unknown beyond just force and mass we used to define our physical world． Entropy （S） also relates to information． I am not sure if entropy relates to the spiritual world， but it does help us feel and comprehend time． Again， it is not a reversible parameter， but a silent and irreversible driving force beyond and behind both the physical and the spiritual world．
