“Cool!” Although the exclamation is now a bit old, it is a common thread that runs through the usage of language. Cool stays cool. But what is behind the word?
If one follows the origin of the word, one finds a connection to the people of the Yoruba represented in West Africa. There the word “Itutu” stands for an outwardly attractive aesthetic but also a calm, stoic expression associated with it.
If you follow the root of the word, the first mention of the actual word “cool” can be found in the American jazz clubs of the 1940s, where high cigarette consumption made the dance bars smoke. The only way to stay “cool” was to open the windows and let in the cool evening air.
In today’s parlance we have many idioms that we attribute to the attributes of cold. This is how you can keep a cool head if you remain reliable and thoughtful. Even when we speak of a “cool” celebration, we mean a celebration that has met our ideal expectations and is therefore remembered.
Cold – colder – cool
When we talk about cold surfaces in terms of haptics, we mean materials with particularly good thermal conductivity. These remove more body heat from the skin, which gives us the subjective impression of a colder surface.
Colder surfaces are perceived as sterile at the same time and can be felt more clearly due to the temperature difference with an additional sense – the heat perception.
Especially Metals such as stainless steel and aluminum stand out as cold haptic materials and are therefore, in the truest sense of the word, a cool option for business cards.
