Threshold. A boundary value at which a physical phenomenon begins to change. This world is constantly evolving. It doesn’t stop at change but also significantly influences other elements and the surrounding environment. Just like the slightest movement of an Amazon butterfly can trigger a storm across the Pacific Ocean. We live in a world where even small changes can have major impacts and outcomes. Recognizing the threshold before a shift occurs can help us prepare for hardships and alert us to danger. These thresholds exist in various fields that make up our world. It’s just that we often don’t know or suspect them. Surviving in this era is an achievement. - Joseph’s “just my thoughts”
In the USA, even in one country, the time difference between the west and the east is 3 hours. People thought that time was a natural thing. But it is not. It's very political. The time that man lives in a unit of minutes is too short. However, since the invention of the steam locomotive, the appearance of faster vehicles made crazy changes to the concept of time. The shift in distance made people realize what time was. Sandford Fleming, an engineer and inventor, asked to unify the time difference caused by long-distance transportation, but people rejected his request. If the boarding time were not fixed, the railroad would be useless. The history of the 24-hour clock was made only about 140 years ago. Even with the invention of high technology, if nothing is consensus, nothing benefits. - Joseph's "just my thoughts"
