Praise be to God, six comprehensive and simplified encyclopedias have been completed. They relate to the history of science in general, and the relationship of earth sciences in particular to space, the environment, energy, water, and natural hazards. These encyclopedias, supported by images and illustrations, aim to serve researchers, general education and university students, and all segments of society, given the scarcity of Arabic references in this field. Specifically, the encyclopedias cover six areas:
Over 1,080 pages, they explore the historical and chronological sequence of the origins of ten cognitive sciences, supplemented by ancient manuscripts and documents on the history of medicine and pharmacy, the history of earth science (geology), the history of chemistry, the history of physics, the history of astronomy, the history of mathematics, the history of geography, the history of botany, the history of zoology, and finally the history of architecture and engineering.
