Descriptions and examples of various processes in manufacturing industries. These are some of the locales where PROCESS MEASUREMENTS are made and where the instruments and sensors that perform the measurements must be installed, commissioned, verified and operate. Many of the databases on process measurements could not exist without such places. Cell Culture Processing Glass Processes Metals Industries Pharmaceutical
| Online databases pertaining to measurement results, measurement practices and related resources for measurement and data analyses. From time to time, we may expand this area and reassign some of our links to subsets of this general category. If you bookmark a certain reference using the page link to this data source, you may not find the reference here in the future, but our database should be intact. Please check in a related category name in such a case. We highlight those databases that charge for access. Astronomical Databases Atomic Physics Databases Bio-Medical Chemical Properties Electronics Environmental Data Geology & GeoScience Identification, Definition or Classification Mapping, Maps, GIS, Charts Measurement & Testing Laboratories Mechanical Properties Metrology & Calibration Molecular Properties-Inorganic Nuclear Properties Oceanographic Optics & Optical Properties Physical Satellite Photographs and Images Solar System Data Statistical Databases & Tables Thermal Weather & Environment

| Physical, chemical, biological, behavioral and other theories that underlie many measurements and various measurement devices. It is also interesting to note that most hypotheses are also confirmed, or refuted, by measurements. Those that are confirmed repeatably by independent observers become known as laws of science or theories, e.g The Law of Gravitation, The Photoelectric Effect Theory. These are distinctly different uses of terms than those offered by some who preach about their strongly held beliefs as theories. They miss the vital steps used in the scientific methodologies of reproducible, measurable and verifiable results.
