Does the choice of the right words and phrases really matter? Winston Churchill and Mark Twain thought it did.5 According to Johnson,5 Twain proclaimed that “the difference between the almost right word and the right word is really a large matter—it’s the difference between the lightning bug and the lightning.” Also, in his famous speech of 1940, Churchill said “Let us therefore brace ourselves to our duties and so bear ourselves that if the British Empire and its Commonwealth last for a thousand years, men will still say, ‘This was their finest hour.’” Johnson5 states, “Try substituting another word for finest in the last sentence. ‘This was their best hour?’ ‘Most noble hour?’ ‘Most courageous hour?’ Nothing else serves as well as finest. You can hear the lightning crackle.”5 In science, it is important for all authors to be able to express themselves fully. Good scientific publication demands accuracy, completeness, and the power of analysis and interpretation.
