Hello. I see you're new here, so you may not have noticed that, although TeX looks very good on Wikipedia when "displayed", it often looks very bad when "inline"; it gets badly misaligned or produces comically gigantic letters on some browsers. That's why I reverted you edit to martingale. Michael Hardy 02:40, 16 October 2006 (UTC)

[edit] inline tex

i see your point that inline tex can be really fugly. a couple questions.

1) is this the way to reply?

2) shouldn't you put all math in math brackets and leave the display properties up to the server? or is this just a dry principal that we'll follow once the server suits our aesthetic desires?

3) currently, the article martingale talks about a stochastic process Xt with no explanation of what that symbol even stands for. if you follow the link to stochastic process you find that it is an indexed collection of random variables for t in some index set. but the definition of continuous martingale makes no sense if you don't mention that t is in \mathbb R or \mathbb R_{\geq 0} or whatever it is. Since the \mathbb R symbol won't display except in comically large font, what do we do? —The preceding unsigned comment was added by Sam Coskey (talk • contribs).

1) Yes, although a reply on your talk page would also do it, since I put your talk page on my watchlist for the time being. But note that you should sign your comments on talk pages by putting four tildas (~~~~) at the end; that causes your user name and the time to appear when you save your edit.
2) For now we have an unpleasant situation, not as bad as it used to be just after TeX became available on Wikipeida (at the beginning of 2003, I think). If you write ex then the e appears aligned with the letters preceeding and following it. But if you write e^{\int x^2\,dx}, then (at least on all the browsers I've used) the whole expression gets centered so that the e is too low, and the whole expression is (again, at least on all the browsers I've used) ridiculously too big. When TeX is used in the normal way, as opposed to the way it's used on Wikipedia, none of these problems occurs. It's also no problem when TeX is "displayed", thus:
\int_{-\infty}^\infty 1\,dx > 3.
3) I've written things like R3; I've seldom if ever used "blackboard bold". I agree that in martingale it should be stated explicitly that t represents time. Michael Hardy 17:58, 17 October 2006 (UTC)
PS: OK, let's try something: R≥ 0. Michael Hardy 17:59, 17 October 2006 (UTC)

[edit] License tagging for Image:Double Screw Bottle Opener.jpg

Thanks for uploading Image:Double Screw Bottle Opener.jpg. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.
