As an alternative view to GJN017 below, the picture immediately above, GJN163, allows the portrayal of vectors into the fourth dimension, as in the top graphic above. To travel one wedge of displacement toward the background (into or behind the plane where the 3D vector space is depicted) is to multiply by a factor of [Meters/Farad]^[1/2] , when speaking conceptually and only in terms of units, or it is to multiply by the quantity [Ke]^[1/2] , when speaking both numerically and in terms of units. Represented by a single wedge expanding toward the viewer, change of position toward the foreground and out of the depiction plane represents division by that factor. Multiply in or divide out by [Ke] for each two wedges of dispacement in the fourth dimension of the abstract space: In the top graphic, start at {[Q0]^2} , the plot point in the 4D space for [the atomic unit of charge]^2 , multiply by [Ke] , and arrive at the plot point for {[hB][v0]} , where [hB] is the atomic unit of action and [v0] is the atomic unit of velocity: {[hB][v0]} = {[Q0]^2}[Ke] = {[Q0]^2}/{[4Pi][k]} , etc Color print 1280 X 960 GIF B & W print
