Scientists in Germany have succeeded in re-determining the Boltzmann constant. Physicists expect that in the next two years they will be able to reduce the uncertainty to such an extent that a redefinition of the kelvin will be possible. The advance represents a major step toward basing the temperature unit on an unchangeable fundamental constant.
