Discussion Overview

The discussion centers around the potential update of constants related to Einstein and Planck units by NIST. Participants examine a list of fundamental unit values and constants, questioning their relevance and the implications of any updates.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant presents a detailed list of Einstein's and Planck's fundamental unit values, questioning whether NIST will update their tables.
  • Another participant expresses confusion, asking for clarification on the purpose of the list and the underlying point being made.
  • A different participant dismisses the list as nonsense, indicating disagreement with the relevance or validity of the claims made.
  • Another comment suggests that the original poster has a grievance regarding the quantity h-bar, although the specifics of this grievance are unclear.

Areas of Agreement / Disagreement

Participants do not appear to agree on the significance or clarity of the original post. Multiple competing views remain regarding the relevance of the constants listed and the implications for NIST updates.

Contextual Notes

Some participants express confusion or disagreement without providing a clear resolution to the discussion. The motivations behind the original post and the relevance of the constants to NIST's work remain unresolved.

Einstein's nine (9) primary fundamental universal base unit values
1) Einstein intensity: [(hG/c^5)^1/2]/sr = 9.8601020(30) x 10^-46 cd
2) Einstein time: (hG/c^5)^1/2 = 1.3511889(33) x 10^-43 s
3) Einstein length: (hG/c^3)^1/2 = 4.0507625(15) x 10^-35 m
4) Einstein substance: [(hc/G)^1/2]/M = 1.6605388(62) x 10^-27 kmol
5) Einstein mass: (hc/G)^1/2 = 5.4563031(18) x 10^-8 kg
6) Einstein current: e/[(hG/c^5)^1/2] = 1.1857531(48) x 10^24 A
7) Einstein temperature: [(hc^5/G)^1/2]/k = 3.5518626(92) x 10^32 K
8) Einstein relative permeability: (e0hc)/e^2 = 6.8517999(55) x 10^1 rad
9) Einstein inverse fine-structure: (2e0hc)/e^2 = 1.3703599(91) x 10^2 sr

Planck's non-primary fundamental non-universal base unit values
1) Planck intensity: [(bar-hG/c^5)^1/2]/sr = 3.9336115(89) x 10^-46 cd
2) Planck time: (bar-hG/c^5)^1/2 = 5.3904639(43) x 10^-44 s
3) Planck length: (bar-hG/c^3)^1/2 = 1.6160204(35) x 10^-35 m
4) Planck substance: [(bar-hc/G)^1/2]/M = 6.6245916(02) x 10^-28 kmol
5) Planck mass: (bar-hc/G)^1/2 = 2.1767500(08) x 10^-8 kg
6) Planck current: e/[(bar-hG/c^5)^1/2] = 2.9722423(67) x 10^24 A
7) Planck temperature: [(bar-hc^5/G)^1/2]/k = 1.4169882(01) x 10^32 K

Legend's http://physics.nist.gov/cuu/Constants/
Planck constant: h = 6.6260693(11) x 10^-34 kg-m^2/s
Newton constant: G = 6.6723635(22) x 10^-11 m^3/kg-s^2
speed of light in vacuum: c = 2.99792458 x 10^8 m/s
Einstein molar mass: M = 3.2858629(47) x 10^19 kg/kmol
elementary charge: e = 1.6021765(31) x 10^-19 A-s
Boltzmann constant: k = 1.3806504(11) x 10^-23 kg-m^2/s^2-K
electric constant: e0 = 8.854187817... x 10^-12 A^2-s^4-rad/kg-m^3
Planck h/2(pi): bar-h = 1.0545716(84) x 10^-34 kg-m^2/s

Will NIST fix their tables?

Huh? Didn't you post this list before without explaining your point? That's just a list of constants. Please: what is your point?

Please stop posting this nonsense.
 
It seems he has some sort of grievance towards h-bar (damned if I know what's wrong with that quantity)
