I&#x27;d love it if someone can make a &quot;RapGenius&quot; for mathematical proofs or actually scientific papers in general,<p>Basically something that takes <a href="http:&#x2F;&#x2F;arxiv.org&#x2F;archive&#x2F;math" rel="nofollow">http:&#x2F;&#x2F;arxiv.org&#x2F;archive&#x2F;math</a> or <a href="http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pmc&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.ncbi.nlm.nih.gov&#x2F;pmc&#x2F;</a> where the user can view and annotate the PDF format,<p>Where you can also click on mysterious&#x2F;not-yet-grokked variable, and it&#x27;ll take you to the definition of that variable or the previous entry of derivation,<p>Maybe also add some cool dank meme&#x27;s on some science or math trivia of the back-story of the author&#x2F;MC of the paper&#x2F;citation.
