In this mini-lecture, we introduce the concept of time dilation, that is, moving clocks run slow. In particular, we focus on: (i) the time dilation equation that relates the time elapsed on a clock moving in one reference frame to the time elapsed on a clock moving in a different reference frame, again using the gamma factor; and (ii) an example illustrating the different notions of simultaneity in the different reference frames once again.
