Medios de comunicación: Para ser transmitido un mensaje, se requiere de un sistema de comunicación que permita que la
información sea transferida, a través del espacio y el tiempo, desde un punto llamado fuente hasta
otro punto de destino, mediante un cable como en el caso de un teléfono, por ondas como en el
caso de las radios, y escritos como los periódicos.
Los mensajes pueden presentarse bajo diferentes formas: una secuencia de símbolos, intensidad
de la luz y los colores de una imagen televisada, la presión acústica de la voz, artículos y textos d
opinión, etc.
Un sistema de comunicación consta de tres componentes esenciales: transmisor, canal de
transmisión y el receptor.

Space-time metric ds2= -dt2+at2dx2+bt2dy2+ct2dz2 (a)how does the area of a rectangle with vertices at ( x=0, y=0, z=0 ), (1,0,0 ), ( 0,1,0 ) and (1,1,0 ) changes with time? (b) if a photon moving in the x direction starts from the origin at t=1, when does it reach x=l? (ds=0 for the trajectory of a photon.) (c) the proper time for a particle is defined by cd=ds. what is the proper time for a particle to move along the trajectory ( x(t)=t, y(t)=0, z(t)=0 ) from t=0 to 1 ? what is the condition on the parameter a so that the velocity of the particle never exceeds the speed of light ?
