[Blindmath] Matrices, appendices, &, now, vertices

Sun Jul 11 19:12:58 UTC 2010

Hi Peter, and others

I've just finished a mathematics degree and did all my work on computer 
using speech and a 1-line (40 cell) Braille display.  I'm really not 
sure that a full page display would have made things any simpler.

Yes, solutions can be very long, but I don't see how having the whole 
thing on a braille display at the same time would be of much assistance 
as you are still only able to look at one bit at a time.  It is very 
easy to move up and down a document to read previous lines, and in some 
ways I think its possibly easier only having the line on which you are 
focusing shown on the display, (it could be potentially easy to lose 
ones place if the display showed lots of lines).

Regarding calculators, I'm not really sure what you mean by "Do you guys 
think a scientific calculator can do calculus and linear
  algebra problems?"   A normal scientific calculator can do all the 
operations you're likely to need to do such problems yourself, (with the 
possible exception of matrix calculations).  However if you were meaning 
could a calculator solve a problem fully without human intervention then 
no, you'd need a symbolic algebra package, Maple, Mathematica, etc, to 
be able to do formal differentiation and integration, etc.
