"I bet most of you think the Coriolis effect makes toilets flush clockwise in the northern hemisphere and counterclockwise in the southern?" So you took a class in college, big whoop, I bet I can take you to school on Linguistics, but you`ll deny you`re an idiot, right?

Well, no need to be haughty about it, etrigan. I don`t consider myself an idiot, no. If I had never taken a physics class in high school, I wouldn`t understand scientific notation either. That doesn`t make the others "idiots". As for the Coriolis effect, it is one of those urban legends that have become "fact". It is said so much, that many believe it.
It`s great that you know so much about this, but there is no need to be so cutting to the others on this site just because you know something that they don`t.

I cannot readanymore of this nonsense.

"Glass" is a term used to describe an amorphous SOLID. Its describes its lack of crystaliine structure and has nothing to do with its viscosity.

Therefore by definition glass IS a solid.

The whole thing is an urban ledgend. Humans have not been making glass long enough to have observed a flow.. The predicated relaxation time for GEO2 at room temperature is 10^32 years (thats 10 with 32 zeros after it years for idiots)

Assuming those figures are wrong and some medieval glass shows flow, wouldnt that mean Egyptian or Greek objects would actually show proportionally more flow being 3000 years old?

The reason old panes of Window glass are sometimes thicker at the bottom is because of glass blowing centrifugal forces. They are often found thick end at the top!

I bet most of you think the Coriolis effect makes toilets flush clockwise in the northern hemisphere and counterclockwise in the southern?

haha quite amusing... I remember discussing the "water IS blue" and the "all seasons are NOT equal in length" topics with my science teacher three-four years ago. he tried to point out that those theories were false, that didn`t work... so he gave me detention.

good thing I wasn`t around many many centuries ago to discuss the "Earth NOT being flat" theory or I`d get more than just detention.

I think soliquid sounds like a fine term for it. But then again, why is this even a topic in the comments?

Alright. As I said, I know nothing about this. And truthfully, it`s not that big of a deal for me. The stuff I`ve read (which I will admit is limited) have said that you are all correct. It`s a liquid and a solid all at once. It`s one of those weird things that defies definition.

Glass-making methods have improved since the medieval times and the cylinder-blown method specifically has distributed the layer of thickness equally in modern (industrial) windows since the 1920s. Now, look at old office buildings, and you`ll see a thicker layer of glass on the bottom, even though the thickness was equal to begin with. Not only that, but gaps appear between the window edge and the glass itself, which I`m willing to bet weren`t there before.

I saw your article but doesn`t offer an incontrovertible conclusion in either direction, Cindy. In fact it leaves off on a very ambivalent note, so I`ll continue believing glass is liquid until new science suggests without a doubt otherwise.

134, run along and occupy yourself with Yu-Gi-Oh, would you?

The discussion whether glass is liquid or not has grown tiresome.
I`ll tell you one thing that is liquid without a doubt: my urine.
And I`ll gladly spray anyone down that continues to give a crap if glass is a liquid.

They didn`t TRY to make it that way. It`s just how it came out.

The link said:
In Mediaeval times panes of glass were often made by the Crown glass process. A lump of molten glass was rolled, blown, expanded, flattened and finally spun into a disc before being cut into panes. The sheets were thicker towards the edge of the disc and were usually installed with the heavier side at the bottom.

I think what Indigo_M was asking is why would glass be *made* with one end thicker than the other, not why it`s placed in windows as such.

It would make sense to set up anything heavy-side down. I know nothing about this topic, so I can only make guesses. But, that would seem logical to me. If If something is wider on one end than on the other, it would make sense to set it up that way, rather than have it be top-heavy.

RichardCaine, I was talking about my college chemistry professors, not my high school chemistry teacher. My professors are confident that glass is an amorphous/viscous liquid material.

Cindy, yes, I read your link, and it doesn`t do much to refute my claim. It doesn`t explain why glass was always made with one end thicker than the other or why it was supposedly installed with the thicker side down. This method of production provides no structural benefit whatsoever.

Forget if it`s thicker at the bottom or not; on older windows, look for gaps between the glass and the window border, specifically on top. If the glass doesn`t entirely fit the whole window space, even if you can move the glass, it suggests the glass has deformed over time and is therefore liquid.

Indigo_M, I don’t claim to know the answer to this question but, unlike you, I have read some of the literature on the thermodynamics of glass. Although the structure of glass has similarities to liquid it doesn’t mean it is a liquid. Believe me, not all high school chemistry teachers are experts.

RichardCaine, I understand the stuff just fine. If there was any doubt in my mind that I might be wrong, I would not have posted. All of my chemistry professors have agreed that glass is a highly viscous liquid. There is technology now that can create glass that does not flow at all (chemists use measuring instruments and test tubes that are made of this glass), but I was referring to the type that has been used the most often, typically in windows of houses that are more than 15 years old.

You said glass was installed with the thicker side down. Why would this be true? It wouldn`t provide any structural benefit whatsoever. I think you are accusing me of bs solely to boost your own ego. You can`t stand having someone know more about any given topic than you do. Get over it.

Indigo_M, You, as well as many others, shouldn’t talk about things you know very little about. First of all, the glass in very old houses has not become thicker at the bottom. The process of making glass was different and it was installed with the thicker side down. Secondly, I guarantee that your understanding of thermodynamics was very limited at 16 so you shouldn’t parrot back information you do not understand. The debate has not been solved and there are actually very intelligent scientists who argue that glass is a solid.

The reason you get more viral infections in the winter time is because your bodily resources are used to maintain body temperature, thus you are less likely to fight infections. So the common cold does have something to do with temperature.

The dark side of the moon refers to our inability to see the opposite side of the moon, it is "dark" to us, not the sun. This guys full of crap if he thinks he`s informing anyone about these facts.

The "water is really blue" explanation is good enough, but I think one more consideration should have been taken. Some water molecules (a very small fraction) undergo autoionization, which is a process where two water molecules react to form hydronium ions and hydroxide ions. A proton from one water molecule is transferred to the other.
I don`t know for sure if this process changes water color, but I think it should have been considered. It is not noticeable in a glass of water, but it is measurable in a body of water as large as a lake or an ocean.

sertrbl, if you go to a very old house and take a close look at the windows, you will find that the glass at the bottom of the window is thicker than the glass at the top.

Anyway, I already knew all of this stuff. If you`re into physics (like me), you should have known this since you were 16.

so your saying that if glass were left alone for a long enough time, it would begin to change shape? at room temperature a liquid is a relitively tightly bound substance that has a constant volume but no constant shape; it changes to the shape of its container. if it doesnt do that it ins not a liquid.

Another scientific fact they should add is that humans did not descend from apes, they descended from Enohead.

Here are some comparison photos of Konec, proving it`s her.

Konec from internet porn pic (same series, apparently), minus all the superfluous and unnecessary nudity:

And sorry, psychoman364, but glass really is a liquid.

No it`s not. Glass it a solid. There art liquids that are so viscuous that they look like solids (like Pitch, for example) but glass is not one of those.

11: glass is not solid, it very dense liquid.
12: light can be considered both particles and waves.
13: grass is not blue, it is actually green
14: the word coin is spelled C-O-I-N

Well, if I run cold water in the bathroom, there is no steam on the mirror. But, if I run hot water, there is steam. No matter what the temp of the actual bathroom is. So, what they are saying does make sense.

"It is incorrectly believed that clouds form because cold air "holds" less water vapor than warm air. Air has no capacity to hold water vapor. It is the temperature of the water itself (and its surroundings) that causes humidity, condensation and clouds to form." I think I`ll believe my University Geo course over a smarmy website.
