Did you know that modern space rockets are influenced by Roman heritage? In other words, the size of current rockets still reflects standards set during the Roman era. Rocket components were transported by rail to launch sites and had to pass through an intermediate tunnel. It was more practical to limit the size of the rocket rather than build a new tunnel. The track width was determined by the steam locomotive, which was adapted to match the width of British wagons pulled by two horses. The width of the track is based on the hips of the two horses, which in turn are derived from the size of a Roman chariot. This phenomenon is called Path Dependency. Humans tend to stick with the past. - Joseph’s “just my thoughts”
When you bleed, the blood comes into contact with the air, it changes from a liquid to a jelly, and then from a jelly to a solid scab. This inherent property of a substance is called its "physical property". If the properties of blood do not change from liquid to jelly and then to solid, people will die from excessive bleeding to death. Thus, physical properties are quite important to our life phenomena. The properties are almost everything in the business of food and chemical products. We can do our business although without an understanding of the properties. But if we cannot understand, or do overlook them, even a coffee shop can't expect to win the competition. So start by understanding the properties. - Joseph’s “just my thoughts”
