Part 2/10:

In nature, phenomena often exhibit a clear and precise direction of time. From waterfalls cascading in foam to colored substances dissolving in water, these instances provoke the age-old question of why natural processes proceed in one direction: what determines the arrow of time? While in everyday life, time seems to flow unidirectionally, the fundamental laws of physics, particularly as they were understood in Boltzmann's time, did not prohibit the reverse occurrence of these processes. The theoretical possibility of a broken cup reconstructing itself becomes an emblematic paradox in discussions of time and entropy.
