>The IS0 31/80000 series mandate italics for quantity names.<<br> _________________________

OK, in scalar maths of the form f(x):= erf(x)

... what is the quantity name ? Surely not f, erf [algos], surely not x [scalar]. If the independent variable(s) x is discretized, that is a quantity name, chaining the dependent variable: that is acceptable but not readable. Functions in mathematics are represented, then calculated from their two inseparable components: the algo and their argument. What does ISO 31/80000 propose for "algo", "argument" ?... what colors ? and what about color blind persons.

Interesting ... and what about "programs".

Read the SP811 that I gave a link to, Jean. Or try obtaining the ISO documents from your local library (they're not free).

typesetting equations

I have over 1100 type fonts loaded in my computer and I can imitate almost any printed book type. Nowhere can I see italics in professional textbooks. Sometimes in scientific journals at the top for a reference or summary if brief.

______________________________

I have never seen Newspaper in italic either. Italic corrupts the normal human eye Fourier transform 5 lines/mm� for one thing, it does not enable comfortable smoothing on the screen, and dithering on the print. No Engineering documents, drawings, standards, books ... have ever been produced before my times and during my times. At school, "industrial drawing" was by hand and of minimum quality not italic that I still have pretty nice. I reject italic in mathematical body, simply. And I have no time arguing with ISO and adepts telling them to mind their business and ignorance. All the fonts I don't want in Mathcad have been removed, including the ISO & ANSI fonts from Smartsketch.

Those who want italic, easy in Mathcad ...even white italic !

I have a stack of books on the handy-reference bookshelf in front of my computer - and I'm just picking them at random:

Heisenberg, Physical Principles of the Quantum Theory, 1949, Dover Press.

Gasiorowicz, Quantum Physics, 1996, Wiley

Aller, The Atmospheres of the Sun and Stars, 1963,Ronald

Kraus, Radio Astronomy, 1966, McGraw-Hill

Goldberg, Genetic Algorithms, 1989, Addison-Wesley

Penrose,**The Road to Reality**, 2005, Vintage

Abramowitz & Stegun, Handbook of Mathematical Functions, 1972, Dover

Woan, The Cambridge Handbook of Physics Formulas, 2003, CUP

Enns & McGuire, Introductory Guide to the Mathematical Models of Science (using Maple), 2006, Springer Science

All, I repeat All, of them consistently use italics to represent variables.

Look at the last page of the following excerpt on Quantum Gravity: http://assets.cambridge.org/97805218/37330/excerpt/9780521837330_excerpt.pdf

or try http://books.google.com/books?id=BIGVrfO84lMC&pg=PP1&dq=%22robotics%22&ei=IOR9SoLLD5KgygTxqKTACg#v=o...

(again, picked at random using google)

Lest Stuart gets accused of stacking his deck, let's add:

Applied Optics and Optical Engineering, R. Kingslake

Roark's Formulas for Stress and Strain, W. Ypung

TTFN,

Eden

Before your time, Mathcad 8 collabs have crucified to exhaustion the crappy italic pi ! Mathsoft changed it for normal. What about the crappy: pi, i, e, dx in Mathematica.

What about it, Jean?

Your contention is that *none* of the printed material you have seen uses italic font representation of mathematical variables. I have given counter-examples. The quality of such fonts is a different issue.

Mathcad can do all that too ! There was upon a time at the beginning of this collab, some Mathcaders flavoring all these gyzmas you are talking about, it didn't survive mostly considering the work sheet efficiency, Mathcad being essentially a Scientific package and the Engineers tool. Also the fact that copying all the gzma styles when pasting to another sheet the gyzma styles are not preserved and need be re-gyzmated !!!.

The other point is that for the closest or the same font you see in the web (in your books also), you would have to have the same !FONT ! and if that font does not install by default when installing Windows, you would have to purchase from foreign source. At this point, as a personal user: fine. But none of your work sheet would be readable by the collab community.

Of the so many 1000's work sheets I have posted in this collab, very exceptionally some have two/three styles, mostly for convenience because many work sheets are huge collections of modules. Though Mathcad is not a "publisher" it produces engineering documentation of exceptional quality and universally readable. Mathematica documentation is crappy (as it means !), the Maple italic makes me vomit, a does the Mathcad italic.

"Mathcad Power users" [Mona expression] don't use italic, but you can do all what you want if you have plenty of time to spare. Again, math font styles and italic aren't the same and might have made this thread confusing. No + to say.

Attached an example of the Mathcad crappy italic.
