This book is one of the most important and greatest scientific classics. "De Re Metallica" contains more than 200 perfect illustrations, and most of them are full page. The book was published in 1556 by Georgius Agricola. Basically all the shown equipment was current until few decades ago. Agricola described and illustrated such methods as amalgamation, and the use of spiral inclines for moving heavy equipment from the surface to underground. The author set out the basic traditions and practices of mining, described the notably elaborate machines needed to keep mines dry and ventilated, and processing and refining, with their devices and chemicals. The language might seem dense and difficult sometimes, but the book is still worth reading.
This book is a perfect example of classic scientific masterpiece. The textbook is crystal clear, well organized, and thorough. "A Course of Pure Mathematics" is great for teaching yourself mathematics. Hardy is a sincerely elegant, fine, incisive thinker, and his unbounded enthusiasm for his subject, duly controlled by British understatement, shines through every page. He conveys the irresistible, almost addictive quality of math. This book is a little quaint. The terminology used by the author is a bit out of date, e.g. ‘sequences’ are ‘functions of a positive integral variable’. But that’s the thing that makes "A Course of Pure Mathematics" so charming. The book contains a lot of examples. This is a great book for teachers, tutors, and certainly students.
A book by an American author, considered by right to be a founder of an adventure western novel as a genre. The two thirds of his works are devoted to an idealized image of the Old West.

This book provides an amazing account of how supposedly-purposeless organs have been found to have a function - all in contradiction to ruling evolutionary beliefs. For example, the "useless onetime third eye" pineal gland turns out to regulate circadian rhythms. Jerry Bergman and George Howe thoroughly dismantle a one-time textbook "proof" for Darwinian evolution - the existence of functionless organs in contemporary organisms inherited from their evolutionary ancestors. Darwinists at one time argued that such "vestigial" organs provided support for Darwinism and didn’t fit within a creationist model. But as Bergman and How show from the scientific literature, labeling an organ "vestigial" was ignorant. This well researched and easily written book should have place on the shelf of everyone interested in the evolution controversy. It also would be a great help for students studying biology.
