Maždaug Mokslas


Maždaug kilogramas, pasirodo.

Dabar pagal patikslintą Planko konstantą kilogramą apskaičiuosim.

In November 2018 BIPM decided to redefine kilogram by fixing the value of Planck constant. Starting 20th of May 2019, the new value is exact, {\displaystyle h=6.626\ 070\ 15\times 10^{-34}\ {\text{J}}{\cdot }{\text{s}}}

The 2014 CODATA results were made available in June 2015[29] and represent the best-known, internationally accepted values for these constants, based on all data published as of 31 December 2014. New CODATA figures are normally produced every four years. However, in order to support the redefinition of the SI base units, CODATA made a special release that was published in October 2017.[30] It incorporates all data up to 1 July 2017 and determines the final numerical values of the Planck constant, h, Elementary charge, e, Boltzmann constant, k, and Avogadro constant, NA, that are to be used for the new SI definitions.

Na ir ką - patikslinsim, kad ir ne pagal tikslias reikšmes šį bei tą apskaičiuosim, taigi ir būsim Beveik Mokslininkai.
