Only when there is a surplus can new things be created. Surplus means having more than what is necessary. Creating something new requires an initial investment in advance. Whether it’s labor or capital—that is, whether labor is purchased with capital—energy can only be used for new work if there is a surplus. Only with prior investment can something entirely new, never seen before, be made. The existence of something that did not exist before in this world results from someone putting in their surplus first. - 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"
