RasayanaIn early ayurvedic medicine, rasāyana is one of the eight areas of medicine in Sanskrit literature. The 11th-century Persian scholar Abū Rayhān Bīrūnī noted an Indian science named Rasāyana, focused on restoring health and rejuvenation through plant-derived medicines. Nagarjunacharya conducted experiments in his laboratory called "Rasashala" and authored Rasaratanakaram, detailing alchemical transformations of metals.
Natural philosophyNatural philosophy, philosophy of nature (from Latinphilosophia naturalis), or experimental philosophy, until the late modern period, was the systematic and research-based study of nature and the physical universe, while ignoring any supernatural influence.
Chinese alchemyChinese alchemy (煉丹術 liàndānshù "method for refining cinnabar") is a historical Chinese approach to alchemy. According to original texts such as the Cantong qi, the body is understood as the focus of cosmological processes summarized in the five agents of change, or Wuxing, the observation and cultivation of which leads the practitioner into alignment and harmony with the Tao.
PhilosophyStudy of general and fundamental questionsThe statue The Thinker by Auguste Rodin is a symbol of philosophical thought.
ArabicCentral Semitic languageArabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic.
ChrysopoeiaIn alchemy, the term chrysopoeia (from Ancient Greek χρυσοποιία (khrusopoiía) 'gold-making') refers to the artificial production of gold, most commonly by the alleged transmutation of base metals such as lead. A related term is argyropoeia (from Ancient Greek ἀργυροποιία (arguropoiía) 'silver-making'), referring to the artificial production of silver, often by transmuting copper.
Alchemy in the medieval Islamic worldAlchemy in the medieval Islamic world refers to both traditional alchemy and early practical chemistry (the early chemical investigation of nature in general) by Muslim scholars in the medieval Islamic world. The word alchemy was derived from the Arabic word الكيمياء (al-kīmyāʾ), which itself may derive either from the Egyptian word kemi ('black') or from the Greek word khumeia ('fusion').
Noble metalA noble metal is a metallic chemical element that is resistant to corrosion and is usually found in nature in its raw form. Gold, platinum, and the other platinum group metals (ruthenium, rhodium, palladium, osmium, iridium) are most often so classified. Silver, copper, and mercury are sometimes included as noble metals, but each of these usually occurs in nature combined with sulfur.
EuropeEurope is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia.Base metalA base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past and today.
LeadLead ( ) is a chemical element with the symbol Pb (from Latin plumbum) and has the atomic number 82. It is a heavy metal, meaning it is denser than most common materials. Lead is malleable and soft, meaning it can be shaped into different shapes and lead has a relatively low melting point. When freshly cut or melted, it appears shiny silvery with a bluish tint, but tarnishes to dull gray on exposure to air.
ProtoscienceIn the philosophy of science, protoscience (adj.protoscientific) is a research field that has the characteristics of an undeveloped science that may ultimately develop into an established science. Philosophers use protoscience to understand the history of science and distinguish protoscience from science and pseudoscience. The word "protoscience" is a hybrid Greek-Latin compound of the roots + , meaning a first or primeval rational knowledge.
PseudepigraphaA pseudepigraphon (also as pseudepigraph) is a falsely attributed work, a text whose claimed author is not the true author, or a work whose real author attributed it to a figure of the past.
