Information about the series: The traditional classic, thoroughly revised and designed for modern use. The focus areas and general educational goals of school instruction have changed in recent years. Version 2.0 takes these changes into account, along with updates and optimizations. The proven content of the blackboard work has been carefully revised, supplemented, and streamlined by removing less important material. For even more efficient use in daily school practice, the chapters on mathematics and physics have been restructured. The revised table of contents and improved subject index make it easier to find what you are looking for. The book also references the expanded online offerings, which include visualizations, information, digital periodic tables, and a scientific database. The interactive version 2.0 of the Great Blackboard Work is also available.
