Welcome to my "my talk" page! Yeah!

Search Google for my name to learn all about me.

Simple links
Hello. Please note that there's no need to write formal languages, since writing formal languages causes the whole word, not just the part in the brackets, to appear as a clickable link, which links to the article whose name is in the brackets. Similarly logical, hyphenated, European, Russian, apocryphal, dogmatic, etc. Michael Hardy 00:17, 18 May 2005 (UTC)

Math notation
Your user page inspires some other comments. You wrote:

$$S=\sum_{n=1}^\infty \frac{1}{2^{n}}=\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + ...$$

You might consider the following form:

$$S=\sum_{n=1}^\infty \frac{1}{2^{n}}=\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \cdots$$

or this one:

$$S=\sum_{n=1}^\infty \frac{1}{2^{n}}=\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \dots$$

In one of these, the three dots ... are centered -- aligned with the preceeding "+" sign. In both of these, the dots are farther apart than in your version. As you'll see if you click on "edit this page", one of these uses \cdots and the other uses \dots. I prefer \cdots in this situation. Also, on Wikipedia, it is conventional to indent "displayed" TeX by means of an invisible colon, thus:


 * $$S=\sum_{n=1}^\infty \frac{1}{2^{n}}=\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16} + \cdots$$
