My physics teacher is using some sort of squiggly symbol that he's calling rho for density. It looks sort of like a backwards g. What is this symbol? How can I include it in my Google Docs reports/notes?
 
Physics news on Phys.org
Rho is the name of the greek letter that he is using. It actually looks more like a stylized p:

Here it is typeset using LaTeX

[tex]\rho[/tex]

Here it is in text

ρ

When handwriting, people often add the curly bit to the stem in order to distinguish it from their handwritten p's. Incidentally, I've also seen a variant of rho in some documents that *is* indeed curly.

You could try copying and pasting the latter version into your Google Doc. Whether it will show up depends upon whether your computer recognizes the character encoding being used.

IF you were using MS Word, then you could go to the menu bar and:

Insert > Symbol...

This will bring up a character map that includes greek letters. I don't know instructions for google docs sorry. It's worth a try though, because some of these freeware programs are deliberately laid out in direct analogy to Word.

Note that the use of rho for density is fairly standard in physics.
 
Is it possible to get a squiggly looking version like the one he's using? Those look too much like a p -- in fluid dynamics, with p's for pressure already in the formula, I'd like to use a character that looks different from a p.
 
I don't know. Again, see if the google docs application has a feature that allows you to insert special characters (see my edited post above). Any p and rho produced by the same software are going to look sufficiently different to distinguish them (unless you do something weird like mixing fonts).

Edit, I just realized that you can access a character map independently of any specific software in Windows XP by going

Start Menu > Accessories > System > Character Map
 
I'm using Windows Vista, but the character map is still around -- I found it by typing "Char" into the start bar and it opened up. After scrolling way the heck down, I found something that looks close -- ϱ -- I'd kind of like a longer tail on it, though, but it'll do for now.

Thanks! :)
