1⟩ Iatrochemistry
2⟩ Alchemy
3⟩ Chalcolithic cultures
What is the meaning of the symbol ≃
Answers
Answer:
(1) Having its roots in alchemy, latrochemistry seeks to provide chemical solutions to diseases and medical ailments. This area of science has fallen out of use in Europe since the rise of modern establishment medicine. However, iatrochemistry was popular between 1525 and 1660, especially in the Low Countries. Its most notable leader was Paracelsus, an important Swiss alchemist of the 16th century. Iatrochemists believed that physical health was dependent on a specific balance of bodily fluids. Iatrochemical therapies and concepts are still in wide use in South Asia, East Asia and amongst their diasporic communities worldwide.
(2) Alchemy, a form of speculative thought that, among other aims, tried to transform base metals such as lead or copper into silver or gold and to discover a cure for disease and a way of extending life.
(3) The term Chalcolithic is a combination of two words- Chalco+Lithic was derived from the Greek words "khalkos" + "líthos" which means "copper" and "stone" or Copper Age. It is also known as the Eneolithic or Æneolithic (from Latin aeneus "of copper") is an archaeological period that is usually considered to be part of the broader Neolithic (although it was originally defined as a transition between the Neolithic and the Bronze Age).
The symbol ≃ is used for equivalence of categories. At least, this is the convention used in this book and by most category theorists, although it is far from universal in mathematics at large.
