Talk:843: Misconceptions

Note: The xkcd forums contain a great discussion of this comic.

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)
