This paper is a summary of the lecture the author gives to introduce special relativity in his introductory engineering physics class. It starts with an explanation of three classic paradoxes using a qualitative understanding of time dilation, length contraction, and non-synchronous clocks. Then, it introduces four-vectors, first the space-time four-vector, and then the energy-momentum four-vector. It concludes with a brief discussion of the meaning of E = mc^2.
