Hi Lupin,

Have you got JPG or GIF versions of the Lancashire Red Rose and Yorkshire White Rose that I could use? I've tried to convert your PNG Red Rose to these other formats but it doesn't work that well.

Thanks, Arcturus 20:22, 9 Dec 2004 (UTC)

[edit] Bee on thistle

You have a great image of a bee on a thistle, but it's not a honeybee, so I have removed it from the honeybee page. I think it's a bumblebee, but I don't know much about European species, and I can't see its head. If it could be positively identified by someone who knows, it might be possible to assign it to another page. Thanks for all the great pictures. I've misidentified species too, and I'm always glad when someone corrects the misinfo. Pollinator 02:56, Jan 2, 2005 (UTC)

[edit] Wikipedia:Image recreation requests

Greetings. I just started the Wikipedia:Image recreation requests project, and I thought you might be interested. Your help would be greatly appreciated. (I got your name from the list at Wikipedia:Wikipedians/Cartographers.) Best regards, – Quadell (talk) (sleuth) 03:19, Jan 30, 2005 (UTC)

[edit] Image permission

Hi. For any of your images that have been tagged {{unverified}}, update the image description page to include source URL and information on copyright status. If you received permission in an email from the image owner, state that as well. If that is the case, what kind of permission you received will determine what to use for the image tag. If the owner agreed to the GFDL license, then you can use {{GFDL}}. If they agreed to use it only on Wikipedia, then use {{permission}}. If the owner does not allow commercial use, then use {{Noncommercial}} but note that these images may get deleted in the future. See Wikipedia:Image copyright tags for more info.

[edit] Image recreation requests

About notifying the original creators: good idea. I'll start doing that. – Quadell (talk) (sleuth) 13:57, Feb 2, 2005 (UTC)

[edit] Thanks for your edits on Timpani

Thanks for the edits on Timpani. I was getting a bit frustrated after not getting many peer review comments the first time I submitted it. I think the "special effects" section needs an image, but I can't think of anything. Any suggestions? (My only idea is to put a snippet of a score or part that includes some special effects... but that's pretty weak as an illustration.) – flamuraiTM 16:13, Feb 6, 2005 (UTC)

If you can't think of a good image then perhaps it doesn't really need one! The only things that occur to me are a picture of some timp mutes or some unconventional beaters and/or playing techniques in action. Also I'd like to see someone write about the differences between timps in north america, the UK and europe - for example, ordering of the drums, different preferences in pedal mechanisms (I'm from the UK and Premier drums are widely used there which I believe use friction clutches although I'm not sure). The article feels very US-centric at the moment to me. Unfortunately I don't really feel qualified to attempt this myself. An overview/list of the various manufacturers would be good, too. Lupin 19:23, 6 Feb 2005 (UTC)
Same here, considering I'm an American. Maybe I'll send an e-mail to one of the European timpanists that has a website. (Update: I dropped an e-mail to Marc Zoutendijk.) And yes, the Premier drums use friction clutches. I'm not sure I agree with you on the list of manufacturers... not sure it's a good precedent... but I'll begin compiling a list on Talk:Timpani. – flamuraiTM 00:11, Feb 7, 2005 (UTC)
Also: I do have one pair of special sticks (the sticks to the far left of this image are MaracaStix, but that's not very obvious visually considering the magic is on the inside). Maybe I could take lay those pics on the score I have where it calls for maracas on timpani. I'll try it when I get my camera back. – flamuraiTM 00:34, Feb 7, 2005 (UTC)

[edit] Damascus steel pocket knife image

What is the copyright status of Image:Damascus_Steel_Pocket_Knife.jpg? Who took it? Boffy b 11:31, 2005 Feb 8 (UTC)

I don't know. The original (uncropped) image was obtained from wikipedia, but I don't know which image it was. You could find it by discovering which article the cropped image was used on (I'm not sure, and it seems to be a failing of the history mechanism that there's no easy way to find out) and look in the history for my edits and see which image I replaced with this one. Lupin 20:19, 12 Feb 2005 (UTC)
It appears from your contributions that the cropped image was never added to any article. (Unless you stealth added it many edits after uploading it, with no useful edit summary.) Or, the article might have been subsequently deleted. dbenbenn | talk 10:12, 13 Feb 2005 (UTC)

[edit] Clobbered reply

Hi Lupin, In case you didn't notice it, I replied to your question at Wikipedia:Image recreation requests. Cheers, dbenbenn | talk 09:57, 13 Feb 2005 (UTC)

Thanks for the heads up - I had missed it. Interesting stuff... I left a possible method for gimpless cropping on the image talk page. Lupin 21:38, 13 Feb 2005 (UTC)
pnmcrop! I should have guessed! Thank you very much; I just used your suggestion in Commons:Image:Random go position.png; it saved me a good ten minutes. dbenbenn | talk 04:14, 18 Feb 2005 (UTC)

[edit] Partial isometries

Suppose W is a partial isomtery. Then W W* is a self-adjoint projection e (so that e2=e). Also assume (as you claim) that it is also the case that

W = W^* W W^* \quad

Then multiply both sides by W:

W^2 = W W^* W W^* = e^2 = e \quad

The square of a partial isometry is a projection only for very special partial isometries (it fails for instance for the unilateral shift). CSTAR 05:05, 9 Mar 2005 (UTC)

You're right. The correct characterisation is
W = WW * W,,

since then WW*=WW*WW* is a projection, as is W*W=W*WW*W. Lupin 14:21, 9 Mar 2005 (UTC)

That characterization is indeed correct, but it seems less interesting for an introductory article. More interesting I think are facts about partial isometries and self-adjoint operators and facts about partial isometrie and K theory. These could go in the article.CSTAR 14:58, 9 Mar 2005 (UTC)

[edit] Image:Cafewall.png

Could you upload a larger version of it? Preferrably to the commons. —Ævar Arnfjörð Bjarmason 04:45, 2005 Mar 13 (UTC)

I replaced the image with a bigger one. Feel free to put it on the commons if you wish. Lupin 06:21, 13 Mar 2005 (UTC)

[edit] Ivy League Gallery

Good job! That change was very useful in clearing up the issues surrounding the Ivy League shields. --Xtreambar 21:51, 6 Apr 2005 (UTC)

[edit] Lucy Cavendish College

Hello. Were the founders not all alumnae, then? Man vyi 14:43, 8 Apr 2005 (UTC)

Hm, I'm not sure. In point of fact, I thought that alumnae was a misspelling of alumni. Having looked the word up, I understand your question - from [1], assuming "founders" is intended to refer to the Dining Group, it is not clear that there were only women in the Dining Group. In fact, it's not clear to me that all of the members of the Dining Group were Cambridge alumnae/alumni at all. So perhaps this sentence should be reworked unless you have a more detailed source. Lupin 00:17, 9 Apr 2005 (UTC)
Perhaps reword along the lines of "Lucy Cavendish was founded in 1965 as a result of an initiative by a group of Cambridge alumnae ..."? So even if some alumni and other males were involved in the actual foundation, the original guiding lights get their due prominence. Man vyi 06:19, 9 Apr 2005 (UTC)
Thing is, nothing I've read on the Lucy Cav website indicates to me that the founders were Cambridge alumni at all - ie it doesn't say that they graduated at Cambridge or were students there, merely that they were working as academics in Cambridge. Perhaps calling them "a group of Cambridge academics" would be more accurate. Lupin 14:53, 9 Apr 2005 (UTC)
That would seem to cover the situation. Man vyi 15:10, 9 Apr 2005 (UTC)
