Where do you study? http://xvedio.in.net/ xvedios  Drawing of the plaque affixed to the Pioneer probe's exteriors. The plaque uses the hyperfine transition of hydrogen to define units of time, which are then used to describe the position of our solar system relative to 14 pulsars (with their frequency described in binary notation derived from the hyperfine transition). Also visible are a nude man and woman, positioned next to a rough representation of the Pioneer spacecraft for scale.
