"Problems worthy of attack prove their worth by fighting back.” That is quote has been attributed to Piet Hein), inventor of the Soma cube, which is how I know of him. > **_Q_**. Is the attribution correct? I wonder because the quote has a nice ring in English that it might not have in Danish, his native language.

> Tæv uforknyt løs på problemerne, men vær forberedt på, at de tæver igen.

It's a Piet Hein quote alright. It doesn't have quite the same ring to it in Danish.
