Check the behind the scenes section, the revision history and discussion page for additional comments on this article's title.
Maxwell's equations were a series of equations used in classical electrodynamics.
A version of these equations were written on a table in one of the habitation hubs of Sanctuary Base 6. (TV: The Impossible Planet)
Behind the scenes
Wiki markup needs cleaning up.
Maxwell's equations are named for James Clerk Maxwell, whom the Fifth Doctor once identified as a friend. (AUDIO: The Haunting of Thomas Brewster)
The version of these equations given in the episode are in their differential form. The variables, vectors and operators written include (the electric displacement field)[1], (the free electric charge density)[2], (the magnetic field in Teslas)[3], (the magnetic field in )[4], and (the differential operator)[5]. In addition, the fourth equation may or may not include Maxwell's Correction, and thus include (the free current density), all shots shown of these equations in the episode are from an angle and distance that make it impossible to tell.
