Scientific Enlightenment:

A amphibious vehicle is a special vehicle that possesses both the characteristics of a car and a boat. It can both drive on land and float on water. Due to the amphibious vehicle's outstanding performance in both land and water travel, it can cross rivers, lakes, and oceans while driving, without being restricted by bridges or boats. Therefore, it has received wide attention and application in transportation, especially in military applications.
The development of amphibious vehicles can be traced back hundreds of years. The earliest recorded amphibious vehicle was invented by Americans in 1805, which was accurately described as "a steam-powered vehicle with wheels that can also sail." From the structure and usage, this invention was indeed a vehicle that could travel on land but also sail on water. In recent years, the research and development of civilian amphibious cars has progressed rapidly, with inventors from various countries designing various styles of amphibious vehicles. For example, a company in England has successfully developed an amphibious car that can reach a high speed of 100 miles per hour on land and a speed of 30 miles per hour on water. It is said that the company plans to produce 100 of these cars. It was not until the military field that amphibious vehicles were truly applied and mass-produced. One of the more famous amphibious vehicles is the German military's Volkswagen 166 amphibious vehicle during World War II. It could reach a land speed of nearly 90 kilometers per hour and a water speed of about 10 kilometers per hour. After being equipped with the military, it was widely welcomed by German soldiers and officers. By the end of 1944, a total of 14,238 vehicles had been produced at the Wolfsburg factory and the Porsche factory in Stuttgart.

Scientific Principles:

Amphibious vehicles, based on Archimedes' principle that the force of buoyancy a body experiences in water is equal to the weight of the water displaced by the body, which is equal to the specific gravity of the water times the volume of the body submerged in water, tanks and armored vehicles also rely on sealed bodies to obtain a certain amount of buoyancy. Since the body is relatively small and far less massive than submarines, the weight cannot be too great, or it will be difficult to ensure positive buoyancy. The armor of general amphibious armored vehicles is relatively thin, and there is usually an additional body float box. Combined with sealing, drainage systems, and propulsion systems (track sliding, water jets, propellers), tanks can navigate on water.
