Review title: Very good tool
Product review: As senior mechanical engineer, I desired a practical tool that could be a general reference for all those uncommon but not so unfrequent problems that require something more than the well known formulas.Till now I used for the more common problems mostly a venerable and extremey useful SKF "Engineers Desk Diary" published by Collins, as well as the "Bosch Automotive Handbook" and a handful of leaflets collected over the years.Now I think I finally have an inexpensive, viable and complete tool for my most demanding mathematical tasks.
