When I was little, I remember receiving an ingenious little pen in my Christmas stocking that could write in about half a dozen different colours - it had multiple biro refils inside which could be selected by clicking the appropriate "clicker thing on the end" for the colour you wanted. (I'm sure there must be an obvious name for the clicker thing, but it completely escapes me!) At the time I never truly understood what these pens were supposed to be used for, and they always seemed a bit gimmicky - why would anyone ever want to write in green or pink for example? Thinking back now, I release they were "mathematicians pens" designed to distinguish not only vectors/scalers, but also matrices, along with variables vs. constants, complex numbers vs. reals etc.. I haven't seen one for about 40 years, but I'm sure someone must still make them given the global potential of the budding mathematician market. Regards, Mike.

I'd prefer the arrow over the character because it's clear the character was intended to be a vector. /BAH

You know, I could've mistyped a word in above sentence but I refrained. You've gotten all sorts of advice on how to handwrite. The reality is, why bother? Learn TeX/LaTeX and let your Math symbols follow a well defined and accepted standard, with or without either Metric System or Linguistics complications. We do all still handwrite. Especially if forced to teach. I recall an experience, where a professor tossed a piece of chalk to the far side of the classroom board to focus on some equation. It was funny. The flying near lightspeed chalk left a mark, nowhere at all near where the CFD professor hoped to hit. He's a CFD SW guy, not a Tennis Player. You know what I mean... There's another different professor, on his Physics chalkboard, for that was the class. He went on and on and filled the board with equations in all directions. Then at the end of the hour lecture, he points out: "By the dot, I mean derivative-with-respect-to-time." I'm sitting there aghast, nowhere has anyone used the dot otherwise?! Perhaps I was still being indoctrinated. Poetic Justice would've been if the CFD guy accurately threw his chalk above the position variable r, instantly making it r_dot, and forcing all of us to go home and redo his derivation with respect to time. That would've been sweet. Here's a sample of really useful -- OK I might be biased here -- handwriting from a certain Physicist Wheeler: http://mahipal7638.wordpress.com/ Since I, like most of you, if HumanInTheSenseYouPretendToBe4Google, are next to your cellphones, you may like to read, to know, this: http://www.newsweek.com/id/233916 Enjo(y)... -- Mahipal http://mahipal7638.files.wordpress.com/2009/04/meforce.pdf The non- handwritten version.
