  • Hendrik Antoon Lorentz [r]: Dutch theoretical physicist (1853 - 1928) [e]
  • James Clerk Maxwell [r]: (1831 – 1879) Scottish physicist best known for his formulation of electromagnetic theory and the statistical theory of gases. [e]

  • Lambert W function [r]: Used to solve equations in which the unknown appears both outside and inside an exponential function or a logarithm. [e]
