Definition of percolation

percolationnoun

sự thấm lọc

/ˌpɜːkəˈleɪʃn//ˌpɜːrkəˈleɪʃn/

The term "percolation" originates from the coffee-making process. In the late 18th century, coffee was typically brewed by pouring hot water over ground coffee beans in a filter. The water would seep through the grounds and into a pot below, creating a rich and flavorful coffee. The process was described as "percolation" by Italian physician and scientist, Alessandro Cagliostro, in 1789. The term is derived from the Latin words "per" meaning "through" and "colare" meaning "to sift". Cagliostro's description of the coffee-making process used the term to describe the movement of liquid through a solid, and it was later applied to other scientific contexts, such as the flow of fluids through porous materials or the distribution of contaminants in groundwater. Today, the concept of percolation is widely used in various fields, including engineering, ecology, and chemistry.
