An <b>amorphous solid</b> is a [[solid]] in which the [[atom]]s do not have an ordered atomic structure. Solids which are not amorphous are called [[crystal|crystalline solids]]. Most classes of materials can be found in the amorphous form, common window glass is a [[ceramics|ceramic]], many plastic materials are amorphous, and metals can be made amorphous by [[rapid solidification]] or [[ion implantation]]
(see also [[Jimbo Wales Minor Issues With New System]])


Amorphous solids are also known as [[glass|glasses]]. However, the term [[glass]] traditionally refers to amorphous oxides, and especially silicate based materials. Amorphous solids which are not oxides can also be called glass, but are often referred to with special terminology, for example amorphous [[metal|metals]] could be called 'metallic glasses' .

There is no fine line between the completely amorphous solid and the crystalline solid with very small grain size. X-ray diffraction techniques can be used to probe the crystal structure of a material, and when some amorphous solids begin to crystallize, there is not necessarily a sudden transition to crystallinity. Thus, some materials cannot be classified as purely amorphous. Scientists use the phrase 'short range order' to speak of crystalline ordering over small lengths scales, i.e. on the order of 1 nm.

There is, however, a very pronounced transition between a very viscous liquid and an amorphous solid. This is the [[glass transition]], which occurs at a temperature significantly below the melting temperature. The transition temperature depends on cooling rate, with the glass transition occuring at higher temperatures when faster cooling rates are applied. The glass transition is a second order transition, in that there is no enthalpy associated with it. Compare this with melting ( a first order transition ) where the enthalpy of melting ( also called heat of melting ) is the energy absorbed by the solid in order to melt it.

'''Titles of History pages'''


Sat Jan 26 21:52:32 2002 (Central) The HTML titles of history pages all read ":encyclopedia article from Wikipedia". --[[user:AxelBoldt|AxelBoldt]]

'''"List only new changes" doesn't work'''

Sat Jan 26 20:31:56 2002 (Central) On [[special:RecentChanges]], the link saying "list only new changes" consistently returns an empty list, even after waiting a while. --[[user:AxelBoldt|AxelBoldt]]

:Right! Same here. Maybe because i'm using a +8 hours offset? --[[user:Luis Oliveira|Luis Oliveira]]

'''[[special:WantedPages|Most wanted page]] listing links with trailing whitespace'''

Sat Jan 26: The "Most wanted" page indicates that a whole bunch of pages want a "Year in Review/Guidelines" page, but that page already exists. Upon poking around a bit more, I found that all of the pages who supposedly had a link to the non-existant page had links with a trailing space, and this was being considered different from the link without a trailing space. For example:

*[[Year in Review/Guidelines|Guidelines]] without trailing whitespace
*[[Year in Review/Guidelines |Guidelines]] with trailing whitespace

The "wanted" page considers the second link to point to a non-existant page.

'''Javascript in generated pages'''

Sun Jan 27 01:52:53 UTC 2002:
Too much HTML is let through unchallenged.
For example, try the following link ''not'' to my user page,
<span style="color:blue;text-decoration:underline;cursor:pointer;" onclick="alert('Whoa.')">Carey Evans</span>.
HTML 2.0 plus tables should be enough for formatting Wiki pages, though I'd prefer to be able to do everything without HTML at all.

'''Ampersand in URLs'''

Sun Jan 27 01:11:52 UTC 2002:
URLs containing ampersands should have them escaped as an entity reference, i.e. &amp;amp;amp;amp;amp;amp;.
This seems to be the only problem stopping the pages from being technically correct HTML 4.0 transitional.
--[[user:Carey Evans|Carey Evans]]

Sat Jan 26

The link to the tarballs from the home page doesn't work. It gives the error "You don't have permission to access /tarballs/ on this server".

Also, there was a problem in the past when the tarballs did work: there was no date in the tarball filename or on the page with the link, so you never knew how old the tarball was.

"Mangled ampersands in raw unicode"

Sat Jan 26 02:55 am PDT 2002

When entering raw unicode such as

&#26009; &#29702; &#12398; &#37444; &#20154;

( the 5 japanese characters for [[Iron Chef]] ) in the editing pane and then clicking the preview button, the preview shows the correct characters, but the text in the preview pane is mangled to be

&amp;#26009; &amp;#29702; &amp;#12398; &amp;#37444; &amp;#20154;

Which when displayed in your browser is what the raw unicode should look like in the html source. Previewing a second time results in

&amp;amp;#26009; &amp;amp;#29702; &amp;amp;#12398; &amp;amp;#37444; &amp;amp;#20154;

and so on. This may be a problem with my browser (IE 5 on MacOS9). Also occurs when doing "edit this page" -- I just had to remove the 15 extra 'amp;' from the above description -- [[Olof]]

:+1, this is quite annoying. I'm not even sure what the text above was supposed to look like now. --[[user:Carey Evans|Carey Evans]]

::The parser seems to be overeager in converting ampersands to ampersand-a-m-p-semicolons when they're followed by the pattern for a character entity in WikiPage::subParseContents(), where I don't *think* it should be doing that. I don't have the current code in front of me though, so I'm not sure exactly what it's doing. Magnus? --[[user:Brion VIBBER|Brion Vibber]]

Sat Jan 26 05:00:39 UTC 2002

At least on Mozilla, long URLs or wide tables like at [[salicylic acid]] or [[Japanese language]] widen the containing table cell so much the rest of the paragraphs are almost impossible to read.
--[[user:Carey Evans|Carey Evans]]

:This would be a general problem with wide tables, images, and pre-tags... The trick is to make them a reasonable size when you write them, I guess. I've rearranged the table on the acid; the Japanese text can be squooshed down a bit; but I notice another thing there. There's a link inside a pre-tag which, being in a pre-tag, doesn't get linked but instead is treated as raw text. Is there any way to deliberately insert a link into a preformatted text chunk? Oh, and I'm also having edit conflicts with myself. Very annoying. --[[user:Brion VIBBER|Brion Vibber]]

::Given that Mozilla really hates &amp;amp;amp;lt;textarea&amp;amp;amp;gt; within tables, getting really slow, I think the best idea is for me to turn off the quick bar thingy. --[[user:Carey Evans|Carey Evans]]

'''Less than/greater than'''

Sat Jan 26 04:33:32 UTC 2002:
Invalid HTML like "<this>" used to be passed through escaped, like &amp;amp;amp;lt;this&amp;amp;amp;gt;.
Now it effectively vanishes.
It's also not very kind to [[talk:insertion sort]], which ends up with invalid HTML.

'''Need more whitespace'''

January 25, 2002, at 19:40 pacific:
The general layout of Wikipedia looks cluttered.
It needs more whitespace to be remotely readable.
--[[user:Damian Yerrick|Damian Yerrick]]

:I agree, especially at the top it's ''very'' busy. For new users, lets just have the page title in &amp;amp;amp;lt;H1&amp;amp;amp;gt;, the Wikipedia tagline, maybe Printable and Edit, then the content. --[[user:Carey Evans|Carey Evans]]

:I agree too - people new to Wikipedia will probably be overwhelmed by all the different links and actions at the top of the page. I suggest simplifing the top to the most necessary things and putting the rest at the bottom. Are two search boxes really necessary anyway?

January 25, 2002, at 13:41:

Shouldn't all links to wiki.phtml go to /wiki.phtml instead?

Better I think for the old addresses to return an http 'see other', so the problem goes away. --

'''SEARCH function doesn't work on "History of..." pages PLUS newbie questions'''

1am, 1/18/2002. Go to any page, click on "view other revisions" at the bottom of the page. You go to "History of..." page (eg. http://www.wikipedia.com/wiki.cgi?action=history&amp;amp;amp;id=Aardvark ). Type into the Search box at bottom and search. You
are taken to the following url, http://www.wikipedia.com/wiki.cgi, and the page just reads "Invalid URL."

--Paulcz {first time on wikipedia, so it's possibly a user error, but it is consistent on different pages).

hmmm. Also, I just tried the preview button at the bottom of this Editing page and nothing happened. I'm on IE 5.5 by the way.

I've just looked on many pages trying to figure out if I should make a page for my name, such as I see for other people. If so, is that just a regular page with the title paulcz?

Also, I've tried to figure out WHERE I should ask questions such as the one I just asked, and have had no luck, so I figured I'd tag it on here. That would be a good thing to tell newbies (eg, "if you still have questions, edit page 'xxxx' to ask them" or something like that.

'''Problem with "diff" link?'''

As of 19:01, 8th January 2001, the diff link on yards/talk gives an inappropriate entry (the diff was added at around the same time, but to a different page). I assume this isn't supposed to happen --AdamW

OK so now it doesn't because I idiotically went and edited the page again. How dumb can you get? --AdamW

'''The first letter of usernames are automatically capitalized upon submission of the "preferences" page.''' 2002-1-1

If a all lowercase string is input into the "UserName" field in the preferences page, the first letter of said string is capitalized.

'''Konqueror 2.1.1 with KDE 2.1.2 cannot render any edit/add page.''' 2002-1-1

The text area for the body of the article is displayed correctly; however, the "summary" text field is rendered ""inside"" and over the article body text area. Also, nothing that would normally appear under the article body text area does not render at all.

'''Japanese Wikipedia marked as ISO 8859-1''' 2001-12-31

http://ja.wikipedia.com is illegible with IE 5.0 (Mac) because its HTTP (MIME) header
includes the line

Content-Type: text/html; charset=ISO-8859-1

The charset should be changed to something appropriate (Shift_JIS or UTF8), or
removed and replaced by the equivalent META tag.

On a similar note, visitors to http://www.wikipedia.com should be automatically
redirected to the Wikipedia written in the language of their choice, as expressed in
their browser language preferences. -- poslfit
:Then how would Dutch/English bilinguals switch to the English version? en.wikipedia.com doesn't seem to have any content. --[[Damian Yerrick]]

The same problem occurs in Netscape 4.77. However, IE5 works fine.
This is very similar and may be related to the problem reported at the bottom of this page.
See [[talk:Ranma 1]] for details.

'''CRLF line endings''' 2001-12-19

In [[David Lynch]], as an example, if you inspect the resulting page, apparently, each ''stored'' line is ended with a CR-LF sequence. However, if I edit it within Lynx, the endings disappear, as they don't exist on Unix. That's all good, but all edits will then differ in all the lines (since no lines match their previous version, everything has a different ending..) See, for example: [[http://www.wikipedia.com/wiki.cgi?action=browse&amp;amp;amp;amp;amp;diff=1&amp;amp;amp;amp;amp;id=RoseParks/Disability_Etiquette&amp;amp;amp;amp;amp;diffrevision=2]] I just fixed a typo in the first lines, and it looks as if everything has changed. Arguably, Lynx, and/or my text editor can be at fault too, but I don't think CR-LF should be stored as part of the text either.. --Chexum

:Somewhere between Lynx version 2.8.2 and 2.8.4, now Lynx also submits texts with the CR-LF line-endings, so it's a bit better. I still think that they souldn't be there on the displayed entries. --[[Chexum]]

:: 'Twas a bug in Lynx. The HTTP standard [http://rfc.net/rfc2616.html RFC 2616], section 2.2, states that everything but entity bodies should use CR-LF line endings.

'''Search logo'''
I'm not sure if this is a bug: when you search for something, the old logo shows up on the search page, as in http://wikipedia.com/search.fcgi?request=happy

'''All's Well That Ends Well'''
When I try to get to the page http://www.wikipedia.com/wiki/Alls_Well_That_Ends_Well--Text ([[Alls Well That Ends Well--Text]]), I get a 500: Server Error. This is the only page that's been doing this to me in recent months, and it's done it every time I've gone there. -- [[Bryan Derksen|BD]]
:Update: I just got into the page by typing ?action=edit etc. into the URL. Looks like a complete dump of the raw text of the play, as I had expected; the only odd thing which might have been causing wikipedia to choke was an unescaped (ie, not HTML-coded)

Revision as of 23:31, 26 January 2002

An amorphous solid is a solid in which the atoms do not have an ordered atomic structure. Solids which are not amorphous are called crystalline solids. Most classes of materials can be found in the amorphous form, common window glass is a ceramic, many plastic materials are amorphous, and metals can be made amorphous by rapid solidification or ion implantation

Amorphous solids are also known as glasses. However, the term glass traditionally refers to amorphous oxides, and especially silicate based materials. Amorphous solids which are not oxides can also be called glass, but are often referred to with special terminology, for example amorphous metals could be called 'metallic glasses' .

There is no fine line between the completely amorphous solid and the crystalline solid with very small grain size. X-ray diffraction techniques can be used to probe the crystal structure of a material, and when some amorphous solids begin to crystallize, there is not necessarily a sudden transition to crystallinity. Thus, some materials cannot be classified as purely amorphous. Scientists use the phrase 'short range order' to speak of crystalline ordering over small lengths scales, i.e. on the order of 1 nm.

There is, however, a very pronounced transition between a very viscous liquid and an amorphous solid. This is the glass transition, which occurs at a temperature significantly below the melting temperature. The transition temperature depends on cooling rate, with the glass transition occuring at higher temperatures when faster cooling rates are applied. The glass transition is a second order transition, in that there is no enthalpy associated with it. Compare this with melting ( a first order transition ) where the enthalpy of melting ( also called heat of melting ) is the energy absorbed by the solid in order to melt it.
