Query: Why translators need to understand what they are translating

It's great that Dodo press produces out of print material, but really! I counted 25 serious errors in the formulas in the first two-thirds of the book. Most of them come from the substitution of a I for a 1, which is this context is confusing. Subscripts which I cannot illustrate here, move up to get mixed with exponents and "minuses" are indistinguishable and mixed up with "dots" meaning multiply. The spelling is atrocious with multiple misspelling but when a mathematical "shell" gets translated as a "mollusc"....yes, literally, really and repetitively, then it is time to get a translator that has some idea of what he is translating. One of the greatest works in human history should be treated better than this.John Riedl
