Where can I find the Greek letter symbols for pasting into replies (e.g., alpha, beta, gamma etc.)?
Thank you for that link, Turbo. More broadly, for mathematical notations (powers and roots, integrals, etc.) is there any way to 'type' those into the forum, or are all such symbols in posts pasted in from other sources each poster may have?
If the latter, as I suspect, is there any simple and free program one can download just to be able to 'write mathematically'?
I'm not familiar with LaTex, but I believe that this forum has the capability to handle such notation.
get a Mac!
For powers and indices, use the X2 and X2 tags just above the Reply box.
For symbols, get a Mac!
xyn ; √x ; ∫x dx
As for getting a Mac, when I finally someday have the funds for a new computer, I'm certainly considering that option already. :)
Get an old 233MHz iMac on ebay for under $100 …
even the very first Macs had symbols like √ ∫ ß µ ∆ ∂ ∑ π on the standard keyboard
Cool. However, I think I'll wait on a new computer till I can get one that is a significant upgrade on my current pc (which has all of a 700 MHZ chip).
So to summarize the 3 options:
1. Bookmark the link to my blog that turbo gave in post #2. The same link is in my current sig.
If you just want Greek letters, as you said, then this is the easiest way.
2. Use LaTex
Note, this is more CPU-intensive for PF's host server, as it must generate an image file for each snippet of LaTex code. At least that is my understanding.
Either insert LaTex code by hand between Latex tags [noparse][tex]...[/tex][/noparse], or
In Advanced edit mode, click the Σ icon to get a drop-down menu of LaTex symbols
For more info, see https://www.physicsforums.com/misc/howtolatex.pdf
and also do a forum search on "latex" for useful discussions.
3. Get a Mac with the symbols on the keyboard
Disclaimer: I am a PC person, who has simply lost count of how many times I've heard tiny-tim say this.
Powers and subscripts are easy to do using bbcode tags.
[ sup ]13[ /sup ]C[ sub ]6[ /sub ] without the spaces inside the brackets reads: 13C6
And here's a link to the [itex]\LaTeX[/itex] tutorial thread: https://www.physicsforums.com/showthread.php?t=8997
I have another method for Greek letters, because I use them a lot. I have set up my windows system on a PC to have two possible input languages. I'm running XP. Here's how.
Go to the control panel.
Select "Regional and Language Settings".
Pick the tab marked "Languages".
Click the button for "Details".
From here, you can "Add" more languages, and also alter "Key Settings"
I include a picture of the steps, as they apply on my machine. Note that I am set up so that LeftAlt-Shift switches between my two available input languages.
I can now type in Greek ωερυ εασιλυ. ΨΑΠΤΙΑΛΣ, ΑΛΣΟ. I don't speak any Greek; I just use the letters as variables.

That is great!
Haven't figured out yet if there's any way to add accents and breathings, though they aren't needed for scientific notation, of course.
Separate names with a comma.
