Pedology (from Greek: πέδον, pedon, "soil"; and λόγος, logos, "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. [1]
Within the new public education systems, mathematics became a central part of the curriculum from an early age. By the twentieth century, mathematics was part of the core curriculum in all developed countries. During the twentieth century, mathematics education was established as an independent field of research.
This is the conceptual perspective of pedology and edaphology, the two main branches of soil science. Pedology is the study of soil in its natural setting. Edaphology is the study of soil in relation to soil-dependent uses. Both branches apply a combination of soil physics, soil chemistry, and soil biology.
Paedology (also spelled pedology or paidology) is the study of children's behavior and development. It may be considered distinct from pedagogy , the art or science of teaching, and pediatrics , the field of medicine relating to children.
Hans Jenny (7 February 1899 [1] – 9 January 1992 [2]) was a Swiss-born soil scientist and expert on pedology (the study of soil in its natural environment), particularly the processes of soil formation.
The history of edaphology is not simple, as the two main alternative terms for soil science—pedology and edaphology—were initially poorly distinguished. [10] Friedrich Albert Fallou originally conceived pedology in the 19th century as a fundamental science separate from the applied science of agrology, [11] a predecessor term for edaphology, [12] a distinction retained in the current ...
The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past.Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales.
