▁moving ▁clock s ), ▁and ▁( c ) ▁served ▁as ▁a ▁basis ▁for ▁further ▁development ▁of ▁relativ ity . ▁Event ually , ▁Ein stein ▁( 1 9 1 2 ) ▁recognized ▁the ▁importance ▁of ▁M ink owski ' s ▁geometric ▁spac etime ▁model ▁and ▁used ▁it ▁as ▁the ▁basis ▁for ▁his ▁work ▁on ▁the ▁found ations ▁of ▁general ▁relativ ity . ▁ ▁Today ▁special ▁relativ ity ▁is ▁seen ▁as ▁an ▁application ▁of ▁linear ▁algebra , ▁but ▁at ▁the ▁time ▁special ▁relativ ity ▁was ▁being ▁developed ▁the ▁field ▁of ▁linear ▁algebra ▁was ▁still ▁in ▁its ▁inf ancy . ▁There ▁were ▁no ▁text books ▁on ▁linear ▁algebra ▁as ▁modern ▁vector ▁space ▁and ▁transformation ▁theory , ▁and ▁the ▁matrix ▁notation ▁of ▁Arthur ▁C ay ley ▁( that ▁un ifies ▁the ▁subject ) ▁had ▁not ▁yet ▁come ▁into ▁w ides p read ▁use . ▁C ay ley ' s ▁matrix ▁calculus ▁notation ▁was ▁used ▁by ▁M ink owski ▁( 1 9 0 8 ) ▁in ▁form ulating ▁relativ istic ▁elect rod ynam ics , ▁even ▁though ▁it ▁was ▁later ▁replaced ▁by ▁Sommer feld ▁using ▁vector ▁notation . ▁According ▁to ▁a ▁recent ▁source ▁the ▁Lor ent z ▁transformations ▁are ▁equivalent ▁to ▁hyper bol ic ▁rot ations . ▁However ▁Var ic ak ▁( 1 9 1 0 ) ▁had ▁shown ▁that ▁the ▁standard ▁Lor ent z ▁transformation ▁is ▁a ▁translation ▁in ▁hyper bol ic ▁space . ▁ ▁Vector ▁notation ▁and ▁closed ▁systems ▁M ink owski ' s ▁space - time ▁formal ism ▁was ▁quickly ▁accepted ▁and ▁further ▁developed .
