The phrase “How to catch a unicorn” is often used to describe a task that is impossible or very difficult to achieve. Unicorns are mythical creatures that are often depicted as being beautiful, graceful, and elusive. The idea of catching a unicorn is therefore seen as a metaphor for something that is highly desirable but very difficult to obtain.
Despite the fact that unicorns are not real, the phrase “How to catch a unicorn” has been used in a variety of contexts throughout history. In the early 1600s, for example, the phrase was used in a book by the English philosopher Francis Bacon. Bacon used the phrase to describe the challenges of scientific research. He argued that scientists should not be afraid to pursue difficult goals, even if those goals seem impossible to achieve.
