Show HN: Sioyek – PDF viewer for reading research papers and textbooks
From a world-class research university, I hold a Ph.D. in math and am pretty good with D. Knuth&#x27;s math word processing software TeX.<p>I don&#x27;t like trying to read PDF files of math on a computer screen:  Typically the fonts are way, Way, WAY too small unless I <i>magnify</i> the display of the file a LOT, but then the lines are WAY too long to fit on the screen forcing me to use the horizontal scroll bar as the main effort in reading the math.  Or put another way, in PDF files of math documents, nearly always there are WAY too many characters per line.  The situation seems to be that the journal wanted to save on paper and ink!!!!  When I develop a document with TeX, I use the TeX commands to <i>magnify</i> the fonts by a LOT.  Bluntly, without a screen at least four feet wide with maybe 16,000 pixels per line, reading the usual PDF file of math is a PAIN.  So, sure, I&#x27;m eager for better ways to read PDF files of math.<p>My reactions to this OP (original post):<p>(1) I have no idea what is meant by a &quot;middle click&quot;, nor would I have any idea where to look up the meaning.  There might be a rule in technical writing -- never, ever, but NEVER, not even once in a whole career, on risk of horrible pain, e.g., a barbed wire enema, use terminology that is not very, VERY, essentially universally, well understood without explanation or at least a reference.  This rule would also apply to acronyms.<p>(2) For searching a PDF file of math, I have no idea how I would type in the math expression to be searched for.  Maybe the software is accepting TeX syntax -- I can guess that even that approach would have problems.<p>(3) For the video, the text is far, far too small to read and goes by far too fast to get any information at all.<p>Broadly I can&#x27;t make any useful sense out of the OP at all.<p>I&#x27;m eager for better ways to read PDF files of math papers, and maybe there is some good work and good utility here, but I have zip, zilch, zero understanding of what is being attempted or how it would work -- nichts, nil, nada, none.<p>Uh, this is not nearly the only place where some technical material could use better technical writing.
