I am witing an essay where I use the Greek letters Phi and phi. I started that paragraph with \begin{math}, and write \Phi resp. \phi whgere I ant to use the letter.
The problem is, that after the forst use of it (a) LaTeX ignores all whitespace, and (b) prints all in italics.
Here's an excerpt:
\begin{math}
Der Zahlenwert des goldenen Schnitts, 1.61803, wird in der Mathematik \Phi Phi mit großem P genannt, ihre Variante 0.61803 \phi phi (=\phi-1) mit kleinem p. \Phi hat also einen Namen wie eine Konstante, wie etwa \pi pi oder die Euler'sche Zahl e. Nun sind \pi und e Zahlen, die durch die Natur vorgegeben zu sein scheinen. Wie aber steht es mit \Phi, also dem goldenen Schnitt?
\end{math}
Caon someone please tell me what my mistake is?
Thanks a lot!

That's because LaTeX ignores all white spaces in math mode, and the math font used for letters is basically italic ;-)
(1) Why do you write the entire text in math mode in the first plase??
(2) If you are a new user why haven't you read any introductions on LaTeX?
Solution: Remove the \begin{math} \end{math} pair and replace the greek letters by e.g. $\pi$
for upright greekletters you will properly need a special font. Have a look at the section about greek in the new LaTeX Companion 2. edition

Because I'm only using the name of the greek letter Phi in a section of my document.

Well, I'm not really a new user of LaTeX, I've used if for several years now. Never for any maths stuff though. I just didn't find the solution in the doc!

That's it! Thanks, this was not mentioned in any doc I have found. Now I know!

Upright or italics for the greek doesn't matter. I was only wirried for the rest of the text!
Thanks again!

That is VERY silly. Put the math in math mode, not the text!
\begin{math} is much too tedious. Type $ or \( instead:
Der Zahlenwert des goldenen Schnitts, $1.61803$, wird in der Mathematik $\Phi$ Phi mit großem $P$ genannt, ihre Variante $0.61803\,\phi$ phi ($=\phi-1$) mit kleinem $p$. $\Phi$ hat also einen Namen wie eine Konstante, wie etwa $\pi$ pi oder die Euler'sche Zahl $e$. Nun sind $\pi$ und $e$.
(My selections of math might be wrong, seeing as how I can't read the text :-)

Off-topic for the original question, but I've wondered if I should always use math mode for normal numbers. It obviously works better for negative numbers, where the "-" should be a negative sign instead of a hyphen. I guess perhaps the "." could be being interpreted differently. Do you just make it a habit to use math mode for all numbers, or is there a particular reason (like the decimal point) that this number should be in math mode?

One reason. By the way, you don't have to think :-)
Rule: I typeset math => I use math delimitors (i.e. I use math modes)
Examples: June, the 6th. But: This equation have $2$ roots.
More seriously, some (La)TeX features apply to math modes (fonts, spaces, ...) then it's really better to think in terms of logic (the rule above).

I, lazily, don't usually put numbers in math mode, and it has bit me on occasions where the math digits look different from the text digits. The best advice is to put math in math mode, even if you could easily type it in text mode. Not all number imply math though!
Shifting off-off-topic quickly, I find it absurd that the "lowercase" digits used for text are found in a math font, but the text font contains the "lining" digits necessary for math.
Did I just say that the character layout of the computer modern fonts was absurd? Big revelation.
> reason (like the decimal point) that this number should be in math mode?
With the default computer modern, the digits come from the same font in math and roman text. The decimal point is taken from different fonts though! I don't see any difference of appearance. Annoyingly, the math decimal is coded at the ":" character instead of "."! Absurd.

Blasphemer! Bring out the comfy chair!

There is a (practical) difference in appearence at large sizes: In the standard setup there are different numbers of optical variants: 12 is the largest point size for cmmi, and 17 is the the largest for cmr. At sizes larger than 12pt, we have a scaled cmmi12 dot and an unscaled cmr dot (size <= 17) or scaled cmr17 dot.
They do look different. This is one reason mathdots.sty uses the math dot for \vdots, etc.: so that these vertically-oriented multiple-dot commands match the horizontally-oriented ones. However, the multiple dot math accents \dddot, etc., use the text dots, trying to match the cm accent \ddot as closely as possible.
