Miniature Hot Air Balloons and Archimedes's Principle of Buoyancy

The history of hot air balloons began in Asia. The Chinese literature dates back to the 1980s, and quoted Chu Gaoliang as an inventor of light aircraft (1). In China, the early unpopular ball was used as a military signal light (2). Today, the Chinese community celebrates the end of Chinese New Year 's holiday (3) by announcing a small hot air balloon called Kung - Ming Lanterns. The mathematical description of the initial recorded buoyancy (and hot-ball behavior) was developed by Archimedes in Greece more than 2000 years ago (4).

Archimedes is also an excellent engineer who developed the Archimedes buoyancy principle and rules of leverage. According to legend, Archimedes discovered the principle of buoyancy and that buoyancy is equal to the weight of flowing liquid. card! "(I found it) Archimedes is also said to invented the Archimedes spiral. Some of the geometric proofs of Archimedes was actually inspired by a mechanical argument that gave him the correct answer. During the siege of Syracuse in Rome he was said to have made a lens, sunlight to Roman ship and huge crane, turn them over and protect the city alone. When the Romans broke the siege in the end Archimedes was killed by Roman soldiers and killed my circle, which is a geometric reference for his sketch at the beach.

One of his most famous scientific findings relates to the buoyancy effect of liquids on a given object and is often referred to as Archimedes' principle. This principle explains that any object immersed in fluid is subjected to buoyancy equal to the equivalent gravity of the liquid moved while immersed. In other words, Archimedes concludes that any object is filled with liquid to keep such objects in equilibrium, and it actually tests forces to replace the waters that maintain this balance I guess.

Archimedes' principle is a very convenient and versatile tool. It can be used to measure the volume of an irregular object (such as a gold crown) or to explain the motion of any object placed in any fluid. According to Science Clarified, Archimedes' principle explains many other examples such as ship float, submarine diving, hot air balloon. Archimedes' principle is also used in various scientific research topics such as medicine, engineering, entomology, engineering, and geology.
