Chapter Chapter 4 in Why Prove it Again?, 2015, pp 19-23 from Springer

Abstract: Abstract This chapter provides an example of how an alternative proof may be used to provide a rational reconstruction of a historical practice. It concerns the following well-known Theorem: n $$\sqrt{n}$$ is rational if and only if it is integral, that is, if and only if n is a perfect square.
