In the case of Ms.Anderson


                           
                           Ms.Anderson, who lives in South California, likes running very much. Astoundingly, she could run
                  a full marathon course in world record time! When she was twenty years old, she began marathon running
                      and she ran 42.195km everyday till she became forty.
                     Now, Nov. 25th 2002, the world record time(accurately, it's not the world record but the world's best
                 performance) of women's marathon is  the 2:17:18 of an English woman, Paula Radcliffe.
                           Therefore, the velocity, v, at which she ran is

                               v = (42.195×10³) / (((2×60)+17)×60+18) = 5.122    (m/s).

                     The total time, t, of the rest system while she was running for 20 years is

                          t = (20×365)×(((2×60)+17)×60+18) = 6.0137400 × 107     (s)

                     Substitutiong these values for the equation (1), the total time, t' , in the system which she was on is determined as

                          t' = (1- (v/c)2 )1/2 ·t = 6.0137400 × 107     (s)

                    Thus the difference of the time between these two systems is

                          t - t' = 0        (s) (acalculia)
