This physical theory uses analogues of rotation matrices containing hyperbolic trig functions. (10[1])A common (10[1])derivation (10[1])in this theory (10[1])that uses the Pythagorean (10[1])theorem considers light bouncing (10[1])between two mirrors. (10[9])In this (10[2])theory, (10[7]-5[2])the integral (10[6])of gamma (10[1])dt (10[1])over c equals the (10[1])proper time. (10[5]-5[2])Lorentz (10[1]-5[1])transformations (10[12])convert (10[6]-5[1])four-vectors (10[4])between (10[1])inertial (10[3])reference frames in this (10[3])theory, (10[1]-5[2])which holds (-5[1])that simultaneity (10[2])depends (10[1]-5[1])on your reference frame. (10[8]-5[3])This theory (10[1])predicts (10[1])that moving (10[1])objects experience time (10[2])dilation (-5[3])and length (-5[3])contraction, (10[1]-5[4])and it was developed (10[1])in one of the “annus mirabilis” papers. (10[1])For 10 points, (-5[1])name this theory (-5[1])of Albert Einstein (-5[1])that he (10[1]-5[1])expanded (0[1])into a (10[1])“general” (10[1])form. (10[2])■END■ (10[11]0[5])
