Simple and fun science trivia

Science is a body of knowledge for studying world and understanding natural phenomena, covering a lot of interesting and useful knowledge. In this article, we will introduce you to some simple and interesting scientific knowledge.

Firstly, it is "inertia" in physics. Inertia refers to property that an object remains at rest or moves in a straight line at a constant speed without an external force. This knowledge can help us understand why cars don't stop while moving, and why moving objects don't experience resistance.

The second is a "gene" in biology. A gene is basic unit of genetic information that can be transmitted and expressed in organisms. Understanding genes can help us better understand relationship between human disease and natural selection, as well as how to improve human health through gene editing technology.

The third is "reaction" in chemistry. A reaction is a process in which two or more chemicals interact to form new substances. Understanding reactions can help us better understand properties and behavior of chemicals, as well as how to design and create new ones.

The fourth is "relationship of supply and demand" in economy. Supply and demand is relationship between supply and demand for a product or service. Understanding relationship between supply and demand can help us better understand market and price changes, as well as how to formulate effective marketing strategies.

These simple and interesting scientific facts are only a small part of much scientific knowledge. Science is a deep and interesting subject that can help us better understand world and bring us closer to a better future.
