Scientific American Handy Book Of Facts And Formulae PDF Download

Excerpt from Scientific American Handy Book of Facts and Formulae When a receipt or a table of weights and measures is wanted in a hurry there is generally a trip to a library and a search through old or indifferent authorities before the matter desired is secured. Each year the "Scientific American" receives 15,000 letters of inquiry and the query editor with a staff of four highly trained specialists, Engineers, Electricians, Chemists and all-around technicians deal with this enormous mass of correspondence. The reading of this vast number of letters shows what people really want to know. Very generally the inquiries are inspired by a desire to improve themselves in their trade or profession, a most laudable desire, and assistance is freely afforded. It is on the basis of actual knowledge of what over 200,000 men really want that the present volume has been compiled largely from the successes which are the literary property of the publishers. Years of effort and considerable sums of money have been spent in securing the information which is now presented in a form which is so usable and portable that even the enormous sales of the "Scientific American Reference Book" and the "Scientific American Cyclopedia of Formulas" will be eclipsed. It is hoped that the usefulness of this little volume will obtain in the shop, the amateur's workshop and the home. It is essentially a book for men but if its success warrants it, possibly a book of "Household" formulas may follow in due time.
