Who says there’s no poetry in mathematics? Consider this equation: This equation translates to: Integral z-squared dz From 1 to the cube root of 3 Times the cosine Of three pi over 9 Equals log of the cube root of e. Before you send me critical emails, I already know that the “log” is “natural log” or “log to the base e”. This limerick apparently dates from that period in history when physicists understood the convention that “log” without qualification meant “natural log” and that if any other kind of log was meant, you had to specify its base explicitly in the notation.
