SCS International is an independent educational reference on chemistry, physics and scientific communication. Chemistry and physics reward precision, so the articles emphasize primary sources, careful notation and the limits of simplified explanations.
How to Read the Reference
Each topic page identifies the question it answers and links to relevant standards, papers or institutional resources where a reader can go deeper.
What We Cannot Do
Because this is an educational reference rather than a business, we do not sell products, provide consulting, complete homework, or offer professional scientific advice. For authoritative technical guidance please consult the primary sources we link throughout the site, such as IUPAC for chemical nomenclature or NIST for physical constants.

Sources
Standards documents, peer-reviewed papers and national-laboratory references take priority over summaries. The reference covers a subject only when it can be explained clearly and cited appropriately.
