[edit] Stanton Prior

Is that how you wanted the map? CambridgeBayWeather (Talk) 11:04, 22 September 2007 (UTC)

Ah, change "Ceremonial county" to "shire_county" and you get the map. I also added categories and a scale line, here. If you look at it now in Google Earth or Goolge maps it gives a nice close up view of the village. I'll fix the coordinates later when I'm at a computer with Google Earth on it. Cheers.

Did you mean Image:StantonPriorMap.gif? I moved it down but I see that there is no license information on it. Did you get it from here? The best place to get help on the correct licence is Wikipedia talk:Copyright problems and the general info is at Wikipedia:Copyrights. It's a difficult area and not one that I'm fully aware of. Cheers. CambridgeBayWeather (Talk) 12:04, 22 September 2007 (UTC)

Kudos/Well done to you and all who edited Stanton Prior -- it's just right.Celia Kozlowski 20:03, 23 September 2007 (UTC)

[edit] Glasses

Appreciate your finetunings on that page James. It is not easy to define them well is it? Rapid quenching heh? I teach P.Chem lab and in it we do an MDSC experiment on polypropyleneglycol to look at a glass transition. I wish I could describe it as 'rapid quenching' but the Tg is at -72 and my cooler wont go below -95 or so. So it takes a while to get there. My students would not call it 'rapid quenching', but the Tg is loud and clear... And no PPG does not crystallize, PEG (the other experiment) does. It is (semi)crystalline and has a Tm at +55C. nl:wikt:Gebruiker:Jcwf 152.1.193.137 13:07, 26 September 2007 (UTC)

PS Maybe we need to involve the Kauzmann paradox into this story? —Preceding unsigned comment added by 152.1.193.137 (talk) 13:10, 26 September 2007 (UTC)
Rapid is a relative term. I think the article still needs a lot of tweaking and as your case illustrates things aren't always necessarily black and white. Thanks for your contributions. Is PPG formed from it's liquid phase and cooled through Tg to it's solid amorphous phase? Because if so, it would appear to be fit to be described as a glass? Jdrewitt 14:26, 26 September 2007 (UTC)
Oh sure below -72C or so it is a glass. At room temperature it is liquid and I suppose you could call it 'undercooled' given that very similar PEO is crystalline there. It's just that PPG has never crystallized.. (because it is atactic) so we dont know its crystalline melting point. the point I was trying to make is that the 'rapid quench' required to make it go glassy is actually a cool down that take 45 minutes or so and you dont need to worry about how 'rapidly' you quench because it cannot crystallize anyway!
Maybe the 'rapid quench' should be amended to 'sufficiently fast' or so, but that would invite discussion of fragility of glass formation and such.

Ok, I think I've found a way for it to all make sense now..let me know...the sentence after the introduction rapid melt quenching states that the quench rate should be 'sufficiently rapid'. I think that this is ok because the rate at which you quench is really dependant on the material involved.Jdrewitt 18:30, 26 September 2007 (UTC)

[edit] Attenuation Coefficient page

Hi, I like your merge of Attenuation coefficient and Linear Attenuation Coefficient pages. It is much improved. I resized the plots and moved them to the right, since I could not see them well. Hope you do not object. --Jarekt 21:31, 11 October 2007 (UTC)

[edit] Common glass properties

Your arguments about the common glass properties are very reasonable. Therefore, I started adding a table with more details on the discussion page. -- Afluegel 18:28, 30 November 2007 (UTC)

[edit] Liquidus temperature

The surface tension in the glass properties table may be deleted, if desired, but the Liquidus temperature is so important in glass production that I reinstated it. We need to find TL for the other glasses as well, if possible. I also inserted a section about the topic in the glass discussion page. Thank you, --Afluegel (talk) 12:36, 14 December 2007 (UTC)

[edit] Re: Silica.jpg

I never deleted the image in question (see here). The image was moved to Commons and was deleted locally by another administrator. I deleted the local talk page of the image as it contained an unsigned statement from a user in a foreign language. I deleted as part of general housekeeping. Cheers. --MZMcBride (talk) 23:59, 15 April 2008 (UTC)

[edit] Actinide → Actinoid page move

Thank you for your contributions to Wikipedia. It appears that you recently copied the contents of a page and pasted it into another with a different name. This is what we call a "cut and paste move", and it is very undesirable because it splits the article's history, which is needed for attribution and is helpful in many other ways. The mechanism we use for renaming an article is to move it to a new name which both preserves the page's history and automatically creates a redirect from the old title to the new. In most cases, you should be able to move an article yourself using the "Move" tab at the top of the page. If there is an article that you cannot move yourself by this process, follow the instructions at Wikipedia:Requested moves to request the move by another. Also, if there are any other articles that you copied and pasted, even if it was a long time ago, please list them at Wikipedia:Cut and paste move repair holding pen. Thank you. --Squids'and'Chips 22:02, 29 April 2008 (UTC)

[edit] Peregrine Falcon

Hi! I reverted your recent edit to the Peregrine Falcon article, because it was incorrect. Females are indeed larger than males—typically quite markedly so. MeegsC | Talk 19:24, 20 May 2008 (UTC)

Hello, thank you. You are of course correct, I meant to add that it is reverse sexual dimorphism and got confused by the previous anonymous users edits which swapped these round and then swapped them back again. I have put the reverse back in since this is accurate. Thanks, Jdrewitt (talk) 19:37, 20 May 2008 (UTC)
No worries! Those vandals do prove to be a pain... MeegsC | Talk 19:50, 20 May 2008 (UTC)

[edit] Personal information

Can you give me a link to where they posted the information? CambridgeBayWeather Have a gorilla 23:39, 25 May 2008 (UTC)

It's possible that was from a tv show. I see that you have decided to get unengaged from that which is probably the best thing. If however the editor follows you to other articles then let me know. CambridgeBayWeather Have a gorilla 08:09, 26 May 2008 (UTC)

[edit] Happy Birthday!

Hey, Jdrewitt. Just stopping by to wish you a Happy Birthday from the Wikipedia Birthday Committee!
