Some Fundamental Definitions In The Science of Chemistry - Alchemy, Medicine and Technology

beaker, chemistry, alchemy, medicine, technology

The history of chemistry is rich and very colorful, even when some concepts and discoveries, led to path of confusion; these same concepts and discoveries, have contributed to the rich heritage of chemistry.

The prescientific past, of chemistry, was incorporated by three overlapping areas of study, which are: medicine, technology and alchemy.

The occult study of nature, practiced by the Greeks, in 1st century AD, was later known as alchemy, a name coined by the Arab community.

Alchemy dominated western thinking for more than 1500 years, after it spread through the east and Europe.

The Greek idea, that matter naturally, strives toward perfection, had great influence, among alchemists.

Alchemy became corrupted too though, and many people used it solely to become young, and make minerals, of lesser value, appear as though they were valuable.

Many alchemists, resulted, to spray painting metals, to make them look like gold, so that they could be sold to wealthy individuals.

Alchemy, did indeed contribute to chemistry though, the chemical methods of distillation, percolation, and extraction, were all invented, by alchemists.

Alright, now let’s look at the medical contributions, to chemistry; as many of you know, our body is composed of many chemical elements, which can be restored, when prescribed the right medicine.

The rise of the need for drugs, and new cures, which could restore the body chemically, drove many studies, which today are very important to help our body be better in time of illness.

Thus people were forced to gain a deeper understanding of chemical elements, and how they could affect the human body; in order to cure it and not hurt it.

The technological contribution made to chemistry, was made through the discovery of new techniques, which were discovered through trial and error.

Since the 17th century, alchemy, medicine and technology, have established, processes which have been important to many chemists around the globe.

The focus change, from objective experimentation, to practical experience or mystical explanation, war largely due to the prescientific traditions, of alchemy, technology and medicine.

The principles of chemistry, are still evolving though, and have been modified overtime; because people learned things about the material world differently, tens of thousands years ago.

Knowledge was only acquired through trial and error, when we began to understand chemistry, for what it is today.

We can make better use of materials and create new ones today, due to the science of chemistry, its powerful quantitative theories, and our understanding of the essential nature of materials.

The way that scientist think, to conduct science, is not as a rigid sequence of steps; instead a dynamic process is put in place, where a real phenomenon is explained and predicted.

Scientist arrive to a hypothesis, about why or how something occurs, through observation, the hypothesis is then tested, in controlled experiments.

In order to explain an observation, scientist gather data, from their experiment, which support their hypothesis, in order to develop a theory.

Chemistry, is a very interesting area of study, if you are into atoms, electrons, neutrons, and protons.

You can actually learn a lot about the world around you, when you have a basic understanding of chemistry.
