What is Alchemy

-

 Alchemy is a field that includes a series of philosophical and experimental practices that were widely practised in the Middle Ages, especially in the West. Alchemists aimed to achieve the goals of transforming matter, especially metals into gold, and prolonging life. Alchemy took place at a time when scientific methods were not yet fully developed and is often linked to mystical or esoteric teachings.




Alchemy was practised in many different cultures and periods in different ways. Periods and regions such as ancient Egypt, the Hellenistic period, medieval Europe and the Middle East saw different variations of alchemy. Alchemists sought to understand the nature of metals and metals, extracted medicines from plants, and sometimes sought mystical and spiritual meanings.


Alchemy has also contributed to many important scientific and technological advances. For example, chemistry, a branch of alchemy, has shaped the modern scientific understanding of elements and chemical reactions. Likewise, alchemists developed practical skills such as metalworking and medicine making.





However, many of the goals of alchemy, especially those of turning metals into gold or achieving immortality, were not realised. Nevertheless, the history of alchemy and its importance in culture continues as part of human endeavours to understand nature and the universe. Today, alchemy often has a historical or symbolic significance and is a field separated from modern science.

Surface Activity: Basic Concepts and Application Areas

-
Resim
Surface activity is an important concept in various fields of chemistry, biology, environmental science and industry. Surface active substances or surfactants play a special role on surfaces where two different phases – such as water and oil – come together. These substances facilitate the mixing of phases or interaction between them by reducing surface tension. This feature allows it to be used in many areas from cleaning to industrial processes. In this article, we will examine what surface activity is, how it works and in which areas it is used. Definition and Working Principle of Surface Active Substances Surface activity is the totality of the properties exhibited by molecules on a surface depending on their interactions on that surface. In this context, surface active substances (surfactants) are chemicals that reduce surface tension by interacting on the surface of liquids or between two different phases (such as liquid-gas or liquid-liquid). Surface active substances have two i...

Discovery of Oil and Its Importance in Human History

-
Resim
Oil is considered one of the most important energy sources of the modern world. However, no one could have predicted that its emergence on the stage of history would play such a critical role in meeting today's energy needs. The discovery and first use of oil heralded major transformations in human history and became one of the cornerstones of the industrial revolution. First Discoveries and Natural Oil Seeps The realization of oil by humanity actually dates back to ancient times. According to historical records, ancient civilizations such as Mesopotamia, Ancient Egypt and China used oil that naturally seeped to the surface of the earth for medical and practical purposes. Especially in Mesopotamia, petroleum derivatives known as bitumen (tar) were used in construction materials for waterproofing, shipbuilding and even religious rituals. It is known that natural gas and oil were extracted in China in the 4th century BC using simple drilling methods. However, these early uses were qu...

Why Plastics Harm Nature

-
Resim
 There are many reasons why plastics harm nature. Here are some of them: Difficulty of Biodegradation: Plastics do not naturally dissolve in nature and take a very long time to biodegrade. Some types of plastic can remain in nature for hundreds or even thousands of years. Danger to Marine and Land Animals: Plastic wastes pose a great threat to marine and land animals. Sea creatures can swallow plastic pieces and drown, block their internal organs or enter the food chain, creating toxic effects for other living things, including humans. Pollution of Water Resources: Plastic wastes cause pollution of water resources such as rivers, lakes and oceans. This leads to damage to living creatures and natural habitats living in aquatic ecosystems. Soil Pollution: The mixing of plastic wastes into the soil can cause a decrease in soil quality and damage to vegetation. In addition, chemicals contained in plastics can leak into the soil and cause contamination of agricultural products or ground...
