    "abstract": "We present the special theory of relativity taking the Doppler effect as the\nstarting point, and derive several of its main effects, such as time dilation,\nlength contraction, addition of velocities, and the mass-energy relation, and\nassuming energy and momentum conservation, we discuss how to introduce the\n4-momentum in a natural way. We also use the Doppler effect to explain the\n\"twin paradox\", and its version on a cylinder. As a by-product we discuss\nBell\u0027s spaceship paradox, and the Lorentz transformation for arbitrary\nvelocities in one dimension.",
