Did You Know?

The Latin word focus meant “hearth, fireplace.” In the scientific Latin of the 17th century, the word is used to refer to the point at which rays of light refracted by a lens converge. Because rays of sunlight when directed by a magnifying glass can produce enough heat to ignite paper, a word meaning “fireplace” is quite appropriate as a metaphor to describe their convergence point. From this sense of focus have arisen extended senses such as “center of activity.”
