| is based on unsound principles. The reason it is harder to pedal a bike at 20 m/s than at 2 m/s is the friction, primarily air resistance, is much greater at the higher speed, which is another way of saying the force due to drag is much greater at the higher speed. Since a bicycle operated under real-world conditions does not have a constant opposing force of 1 newton at different speeds, the statement in the article does not apply to the real-word operation of a bicycle. ] (]) 13:38, 3 August 2011 (UTC) | |||

Photodiode edit?
Please see your (apparent) edit here: http://en.wikipedia.org/search/?title=Photodiode&diff=prev&oldid=432552198 Now the article seems to state that in both modes, the cathode is positive. This does not seem to make sense. If I knew what was correct, I'd edit it myself, but it's because I'm suffering from some confusion on that topic that I looked up the article in the first place. Assuming you know, or at least have a strong opinion, would you take a look and set it right? Thanks. Tzf (talk) 22:30, 27 July 2011 (UTC)
- The cathode is positive when the photodiode is reverse biassed. Either the photodiode builds up its own positive voltage on the cathode or else an externa circuit impresses a positive voltage on the cathode. I believe the text is currently correct but I agree this sounds confusing. I can't think of an application where the photodiode is forward biassed since the photocurrent woudl be lost in the "normal" forward current. --Wtshymanski (talk) 13:09, 28 July 2011 (UTC)
Grrr, Grr...go away
I'm an uncivil editor, I am, I am. I might dare to disagree with you. (I might even, rarely, be right).
Don't tell me!
When complaining about one of my edits here, PLEASE PLEASE PLEASE do not give me the name of the article in question, nor give any specific hints. If possible, use a different IP address to comment on the edit. I love puzzles and I'll happily devote all my spare time to figuring out which of the last 20,000 edits has displeased you.
"Why did you change that?" --192.168.2.3 - now there's a comment that I can really spend time on. (Don't even give a date stamp...sometimes I don't log in for a few hours, this adds to the challenge.)

If you parse "official" narrowly enough, you can make it mean anything you want...though it helps to have an admin hammer to make consensus. --Wtshymanski (talk) 21:37, 24 November 2010 (UTC)

Oh thank you, I was *so* worried I wasn't going to have permission from some anonymous person on the Misplaced Pages to have my own opinions.--Wtshymanski (talk) 15:32, 26 November 2010 (UTC)

- Don't worry if you disagree with me on an edit. Just have me blocked. That way, you're sure to get the right version of the article preserved. --Wtshymanski (talk) 16:12, 11 July 2011 (UTC)
