A very good point.

Ha, that gives me hope! I always thought it was my fault that maths often seems to make no sense (only half joking. I've still never seen any sensible reason for 1 not being a prime number).<br></blockquote><div><br></div><div>I sympathize with this, and there are many reasons 1 could be considered a prime number, but for definitional reasons mathematicians settled on the convention that it was not (mainly so that every integer has a unique prime decomposition in the <a href="https://en.wikipedia.org/wiki/Fundamental_theorem_of_arithmetic">fundamental theorem of arithmetic</a> ). It would not surprise me if alien civilizations went the other way and chose to instead consider 1 prime. I think most alien civilizations treat 2*Pi (6.28...) as the important constant, rather than our bizarre definition as the ratio between circumference and diameter (circumference to radius is what makes the most sense, and many physical and mathematical equations are <a href="https://www.tauday.com/tau_manifesto.pdf">much cleaner</a>).</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Personally, I don't think it's even necessary to get into 'esoteric areas of higher mathematics' to find oneself in the fiction section.<br></blockquote><div><br></div><div>You could write false physical equations all day using the language of physics, but that doesn't mean the field concerns fictional entities.</div><div><br></div><div>Jason </div></div></div>
