This question is actually much older than what it appears to be. The famous **fundamental anagram of calculus** (Newton, 1676) > 6accdae13eff7i3l9n4o4qrr4s8t12ux is an anagram of the Latin > Data aequatione quotcunque fluentes quantitates involvente, fluxiones invenire; et vice versa (less than 140 symbols). In modern English it means > Given an equation involving any number of fluent quantities to find the fluxions, and vice versa or, in Arnold's interpretation > It is useful to solve differential equations
