It’s slightly old but I only recently saw this article about how Google Translate make use of linear transformation.

The new book on my desk **eta products and theta series identities** has the following quote in the preface.

In der Theorie der Thetafunctionen ist es leicht, eine beliebig grosse

Menge von Relationen aufzustellen, aber die Schwierigkeit beginnt da,

wo es sich darum handelt, aus diesem Labyrinth von Formeln einen

Ausweg zu finden. Die BeschÂ¨aftigung mit jenen Formelmassen scheint

auf die mathematische Phantasie eine verdorrende Wirkung auszuÂ¨uben

– G. Frobenius, 1893

The quote was rendered as:

In the theory of Thetafunctionen it is easy to an arbitrarily large Establish set of relations, but the difficulty starts here where it is a question of this labyrinth of formulas a

To find a way out. The preoccupation with those formula masses seems auszuuben to the mathematical imagination a searing effect.

Perhaps, I can feed the same passage in a years’ time to see whether the translation has improved.
