Interesting article.

They can tell you what the temperature will be, 25 years from now.
They can tell you all about how the eye and ear evolved.

But glass? Well, they're not really sure about that one. No consensus yet.

...if cooled infinitely slowly

When does one detect a drop in temperature, at the end of infinity?

NYT: “It is well known that panes of stained glass in old European churches are thicker at the bottom because glass is a slow-moving liquid that flows downward over centuries. Well known, but wrong.”

Hmmm. The NY Times writer (or typist) does not cite it but the article is eerily similar to this:

http://math.ucr.edu/home/baez/physics/General/Glass/glass.html

...which is copyrighted, dated 1996, and starts out: “It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom. This is not true.”

The New York Times: Outrageous liberal bias, insipid PC drivel, plus the occasional excellent science article.

"...the arrangement of atoms and molecules in glass is indistinguishable from that of a liquid.."

I thought that glass had more short range order than liquid.

Thanks for the post.

David Chandler, mentioned in the article, is scary-smart.

Rumor has it that when he was at Penn, a gag greeting card was circulated with a drawing of a smug-looking dragon on the front, with the obligatory puff of smoke.

The caption on the inside read, "Ha! Ha! I'm David Chandler, and you're not."

Cheers!

Bump for Monday reading.

I loved those “slow glass” sci-fi stories.

Glass fascinates me. Molten glass especially.

I occasionally play with glass in the kiln & furnace. :)

Maybe the glass was thicker at the bottom by design, rather than slow flow, or by chance.

[dalereed]

It's a liquid!

I took some 3’x4’ glass window pains out of a building that we remodeled that were about 60 years old and miked them and every one of them was thicker at the bottom than at the top.

It definatly is liquid silica.

[Impy]

Some people think glass is a slow-moving liquid?

“Many people tell me this is very contentious. I disagree violently with them.”

LOL!
