In the animation “Finding Nemo,” the main character, Nemo, asks questions about the sea and where he lives. “What is the sea?” Hearing this, the dolphin puts Nemo on its back and jumps over the water to reveal her world. When you are in the sea, you do not know what the sea is. However, when you rise above the surface, you can see that the sea is a place where water gathers at a low level, and above it are air and land. She eventually realizes that she is also on the ground with water. If you want to understand the essence and grasp the reality, you must step out of the place you belong to for a while. Further development and reform can be expected. - 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”
