Kính thiên văn là một trong những thiết bị được cho là đã tạo nên cuộc cách mạng khoa học trong thế kỷ 17. Nó đã làm sáng tỏ nhiều hiện tượng của bầu trời và có ảnh hưởng quyết định đến cuộc tranh cãi giữa những người theo trường phái địa tâm truyền thống và những người theo trường phái nhật tâm do Côpécníc khởi xướng.
This history of woodworking hand tools from the 17th to the 20th century is one of a very gradual evolution of tools through generations of craftsmen. As a result, the sources of changes in design are almost impossible to ascertain. Published sources, moreover, have been concerned primarily with the object shaped by the tool rather than the tool itself. The resulting scarcity of information is somewhat compensated for by collections in museums and restorations.
The mission of this series is to improve the state of the art of software craftsmanship. The books in this series are technical, pragmatic, and substantial. The authors are highly experienced craftsmen and professionals dedicated to writing about what actually works in practice, as opposed to what might work in theory. You will read about what the author has done, not what he thinks you should do. If the book is about programming, there will be lots of code.
