Encyclopedia
A scientific technique is any systematic
Systematic process
A systematic process is often closely associated with critical thinking.In general the application of a systematic process is regarded as a means of management aimed at reducing the number and severity of mistakes, errors and failures due to either human or technological functions involved.Use of...

 way of obtaining information
Information
Information in its most restricted technical sense is a message or collection of messages that consists of an ordered sequence of symbols, or it is the meaning that can be interpreted from such a message or collection of messages. Information can be recorded or transmitted. It can be recorded as...

 nature or to obtain a desired
Desire (emotion)
Desire is a sense of longing for a person or object or hoping for an outcome. Desire is the fire that sets action aflame. The same sense is expressed by emotions such as "craving" or "hankering". When a person desires something or someone, their sense of longing is excited by the enjoyment or the...

 material
Material
Material is anything made of matter, constituted of one or more substances. Wood, cement, hydrogen, air and water are all examples of materials. Sometimes the term "material" is used more narrowly to refer to substances or components with certain physical properties that are used as inputs to...

 or product
Product (business)
In general, the product is defined as a "thing produced by labor or effort" or the "result of an act or a process", and stems from the verb produce, from the Latin prōdūce ' lead or bring forth'. Since 1575, the word "product" has referred to anything produced...

.

Scientific techniques can be divided in many different groups, e.g.:
  1. Preparative techniques
    1. Synthesis techniques, e.g. the use of Grignard reagents in organic chemistry
    2. Growth techniques, e.g. crystal growth
      Crystal growth
      A crystal is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. Crystal growth is a major stage of a crystallization process, and consists in the addition of new atoms, ions, or polymer strings into...

       or cell culture
      Cell culture
      Cell culture is the complex process by which cells are grown under controlled conditions. In practice, the term "cell culture" has come to refer to the culturing of cells derived from singlecellular eukaryotes, especially animal cells. However, there are also cultures of plants, fungi and microbes,...

    3. Purification techniques e.g. those in chemistry
  2. Measurement techniques
    1. Analysis techniques, e.g. ones that reveal atomic or molecular composition.
    2. Characterization techniques, e.g. ones that measure a certain property of a material.
    3. Imaging techniques, e.g. microscopy
      Microscopy
      Microscopy is the technical field of using microscopes to view samples and objects that cannot be seen with the unaided eye...


Instruments

In many cases these methods have evolved into instrumental techniques that require expensive equipment. This is particularly true in sciences like physics
Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

Chemistry
Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds....

Astronomy
Astronomy is a natural science that deals with the study of celestial objects and phenomena that originate outside the atmosphere of Earth...

. It is customary to abbreviate the names of techniques into acronyms, although this does not hold for all of them. Particularly the advent of the computer has led to a true proliferation in the number of techniques to the point that few scientists still have a good overview over all that is available. See, for example, the list of materials analysis methods and :Category:Scientific techniques.
