National Institute for Standards & Technology (NIST)

350+ constants identified by the National Institute for Standards & Technology, a de facto challenge.

Eventually every constant will be associated with notations and other functions. Each will be discussed on our constants page. All communications with the NIST people will be referenced from this page.

Please note: NIST and ISO and the BIPM adopt the CODATA numbers as their standards.

Key standards: Planck Length, Planck Time

There is much more to come…
