When was the cold invented?

The concept of "cold" as a temperature condition has existed since ancient times, as people have long recognized the effects of low temperatures. However, the modern understanding and scientific study of cold temperatures began to develop in the 17th century with advancements in thermometry. The invention of the first practical thermometer by Galileo in the early 1600s allowed for the measurement of cold temperatures, paving the way for further exploration of thermodynamics.
