Methods and techniques that are useful in a broad range of scientific and engineering applications include statistical methods, analytical chemistry, crystallography, microscopy and microanalysis, geographic information systems, and electronic data acquisition. Because many methods and techniques are themselves important fields or subfields of science addressed elsewhere in the Open Directory, this category contains numerous cross-links to other categories.

Imaging science is the discipline that combines computer-based imaging techniques with a variety of data acquisition tools to increase the range of properties that scientists can observe.
The generic issues of imaging science include image-data acquisition; image reconstruction and processing; image recording and distribution; image display, analysis, and evaluation; human vision; and the mental processes involved in observation.

If the primary purpose of the website is to sell imaging systems or their support,

Websites about the study of the use of electronic, optical and scanning probe microscopes to study samples. Pages about manufacturers, distributors and dealers of microscopes should be submitted to Science/Instruments_and_Supplies/Laboratory_Equipment/Microscopes.
The Scientific Method is the systematic method of analysis of phenomena, devised to permit the study of repeatable, thus reliable, knowledge. This category deals with the theoretical and practical aspects of the scientific method. We will not admit sites presenting actual discoveries, or their practical and commercial applications. These sites will be automatically rejected.

Stereology is the science of determining geometric quantities by sampling and estimating. Measures of size include, how many, length, surface area, and volume.
