6 Responses to 10 Common Science Myths [Video]

1. Glass is an amorphous solid but it is not because of this that stained glass is thicker at the bottom. This very statement is a myth in itself!

2. Close, but not quite. This list of myth contains a myth!
   While glass is an amorphous solid, as specified, it doesn't flow at room temperature. Old windows are not thicker at the bottom due to the glass flowing, but rather because of the methods used to create glass at that time could not create perfectly flat panes.

3. Number 3 is wrong. Glass does not flow. Although Wikipedia itself is not authoritative, the cited references are. The myth that glass flows over time has been debunked numerous times.

4. Here is a lovely paper written on the matter of glass flow. It proves that glass flow occurs so slowly at these temperatures that it is not significantly measurable. So the gravitational effects acting on this anamorphic solid does not cause a measurable difference in the thickness of the glass itself. I can only praise the good methods of calculation and clear style of the paper. http://www.df.unipi.it/~leporini/DFWebSite/Review…

   Citing wikipedia on scientific matters is usually not considered wise. Nor is using it to make a video against scientific myths. That's also how myths actually start, which is what was trying to be dispelled in this video. Next time try consulting real scientists.

   Please see "Do cathedral glasses flow?" from The American Journal of Physics
   and "Antique windowpanes and the flow of supercooled liquids." from The Journal of Chemical Education for further reading.

5. Okay guys, I think we get it, glass doesn't flow.

   • Glass has no flow. This makes it a terrible rapper, which is why you don`t wrap Christmas presents in glass.
