[BlindMath] Typing Math and Science Quickly and Understandably

Jonathan,

Your statement about comparable efficiency is, in my humble
opinion of a professional pure mathematicians with many years of
experience at lecturing, research, taking notes, etc., completely
false. While we will not settle it here directly, a strong indirect
argument is that if they were of comparable efficiency then more
professional mathematicians would use it for preparing lecture notes,
articles, etc. As I'm sure you know, the amount of professional pure
mathematicians using word is absolutely negligible (to the extent that
people who use it are subjects of anecdotes passed around during
conference dinners, etc.). 

As for specifically taking notes in pure maths lectures, I have
absolutely never seen anyone who'd use word for this purpose, only
either latex or markdown.

(There are also of course other issues, of interoperability and so on,
which are also important, and if one consider these, then obviously
using word for anything at all is, for lack of a better word,
irresponsible) 

Best,
Lukasz

P.S. As for usage of \ in markdown, I can't agree with you: the example
of Brandon was a transcription, and it was mildly important to
distinguish between newlines and paragraphs. But even in markdown
for say taking notes, if you want to produce material which works both
for you and for sighted users then the cleanest way to write say
multiline equation is with explicit \
