I&#x27;m considering tackling this book: &quot;Einstein&#x27;s Theory: A Rigorous Introduction for the Mathematically Untrained&quot; by Øyvind Grøn and Arne Næss which claims to provide &quot;an introduction to the theory of relativity and the mathematics used in its processes&quot;.<p>This preview on Google Books [ <a href="https:&#x2F;&#x2F;books.google.com.sg&#x2F;books?id=7zFalCF_LiEC&amp;printsec=frontcover#v=onepage&amp;q&amp;f=false" rel="nofollow">https:&#x2F;&#x2F;books.google.com.sg&#x2F;books?id=7zFalCF_LiEC&amp;printsec=f...</a> ] appears to show it starts from basic mathematical principles and builds on from that.
