Why is the "B" in "Before time" capitalized?
If it's a reference to "B.C.", what's the link here?

When I took Calculus-based Physics in college (2003), my professor taught us that glass was an "extremely viscous fluid." When was glass reclassified as an amorphous solid?
Smperron (talk) Your professor was simply incorrect. Glass never was, and has never been, an "extremely viscous fluid". Molten glass is a "molecular liquid" where the viscosity depends on temperature. 75.103.23.206 22:14, 13 December 2012 (UTC)
"Extremely viscous fluid" is just another way to describe an amorphous solid (as opposed to the crystallic solid). There is no sharp cut-off between these states. Just at some point it starts feeling solid enough, so it gets called a solid. See the Pitch Drop Experiment [1] for an example (though glass is obviously harder than pitch). 108.162.246.11 19:21, 16 January 2014 (UTC)

I had a chemistry professor in 2011 tell me that glass flowed, even citing old buildings with thicker glass on the bottom. I tried to argue against it, but I was interrupting a lecture. I discussed it with some students later, though. 108.162.237.64 00:49, 1 February 2014 (UTC)

If you think you had a problem, try convincing anyone that weather turns into seismic activity and vice versa.

Is there really a law or custom about the first Tuesday in February?, or is that just a misconception? Mountain Hikes (talk) 17:55, 4 January 2016 (UTC)
