Per your question on Wikipedia:Vandalism in progress - yep, your handling of the Transhumanism vandal was perfect. I'm always impressed by how quickly trash like this (and subtler stuff too) gets spotted and removed. Keep up the good work. -- Finlay McWalter | Talk 23:34, 16 Feb 2004 (UTC)

Hello, I answered your question regarding Fourier transforms and uncertainty on my talk page. Cheers, AxelBoldt 13:31, 26 Feb 2004 (UTC)
Hi Omegatron - nice work on the gyrator. Would you mind telling me what software you used in drawing the circuit diagram...? Suggestion: Let's rename R1 > R0, because that's basically given, and R2 > R, leaving essentially C and R to play with. --Palapala 09:24, 28 Feb 2004 (UTC)
- I used Klunky schematic editor. It is online at
- Then I took the screenshot and edited it a bit to make it prettier. I also drew a bunch of pictures for opamp configurations, so I can make an article on that, but I left them on my work computer. What do you mean that R0 is given? - Omegatron
- Oh you mean that the inductor you would want to simulate would already have the R1 defined? How about we name it R1 --> RL, like a real inductor would have it labeled, and then the other R2 --> R. By the way, one of those links has the opamp inputs inverted. Do you know if it makes a difference? It seems like it would... - Omegatron
- I will do the calculations sometime tomorrow and double check. And maybe send that site an email if I can. - Omegatron
In thermionic emission you added that it was initially discovered by Professor Guthrie in 1873. I did a little searching and the only person I could find was physicist Frederick Guthrie in London who lived from 1833-1886, and did research on heat, magnetism and electricity. I assumed he was the right guy. Then I found Scottish physicist Peter Guthrie Tait (1831-1901) and found he did work on thermoelectricity. Which is right? I assume it is Peter, but I already assumed too much, so I will ask the source and leave it undefined for now... - Omegatron
- I wish I knew which Guthrie it was, the source I used did not specify the full name (unfortunately) but I assumed it to be a last name. -- RTC 06:42, 8 Mar 2004 (UTC)
- Ok, thanks. I will keep searching... - Omegatron
thanks
thanks for figuring out how to force png rendering without altering appearence! Perl 23:04, 9 Mar 2004 (UTC)
- Congratulations. That seems to be fairly general... --Palapala 17:19, 2004 Mar 10 (UTC)
Hi, since you're a DSP engineer, perhaps you would be interested in helping out with the Electronics wiki-textbook. http://wikibooks.org/wiki/Electronics
- Yes, I would love to. - Omegatron 20:48, Mar 19, 2004 (UTC)
Thermioic Emission/Dots
Omegatron: I wasn't able to get over to the physics library before it closed that day; I'll try again soon if I get the chance.
The Dot project is intended to create maps for the Ram-bot generated articles. See Siler City, North Carolina for an example. The maps on my user page are just intended to track the progress of the project. - Seth Ilys 17:13, 26 Mar 2004 (UTC)
Reason for HTML's irrelevancy
The numeric HTML entities for colon and semicolon are highly irrelevant, because they are never, ever used. In fact, the only time I have ever seen a numeric entity used for either of these is in the MediaWiki:Punctuation_marks box, and that's only because Wikipedia attaches a special meaning to a colon, not because the HTML needed it for any reason. You can represent the character A in HTML by typing A, but no one ever does, because it's never necessary or useful. The same goes for the numeric entities for the colon and the semicolon. —Bkell 21:35, 5 Apr 2004 (UTC)
- Right... But I needed to know it in order to put it in the punctuation box, and the information wasn't on WP. :-) I figured that was reason enough to include it. Maybe it should just mention that HTML entities are the same number as ASCII for letters and punctuation? - Omegatron 21:38, Apr 5, 2004 (UTC)
- Well, Character encodings in HTML already says, "Decimal and hexadecimal HTML character references can also be used, based on the [[Unicode] numeric code for the character encoded." That should be enough information for anyone who needs to encode a colon as :. I imagine they would visit HTML instead of Colon (punctuation), as HTML is more specific to the problem they are having. (To be honest, I would go straight to the HTML spec myself.) There is no reason to include a numeric HTML entity on every page about a punctuation mark or letter or number or other character, especially if it's one that is normally just typed. —Bkell 21:47, 5 Apr 2004 (UTC)
