Walter Elsasser proposed that magnetic field intensity saturates near an Elsasser number of one. The Elsasser number is \Lambda=\sigma B^2/\rho \Omega where \sigma is conductivity, \rho is density, and \Omega is the Earth's rotation rate. Elsasser scaling is setting \Lambda=1 so that the magnetic field scales as B=\sqrt{\rho\Omega/\sigma}.
Sigma Sigma Rho was created in 1998.
