That glass is a liquid
objection!
glass is a solid. the misconception that glass is a liquid arises from a misreading of the work of German physicist Gustav Tammann who studied glass and described its behaviour as it solidifies. He observed that the molecular structure of glass is irregular and disordered, unlke the neat arrangement of molecules in, say, metals. Reaching for an analogy, he compared it to ‘a frozen super-cooled liquid’. But saying that glass is like a liquid does not mean that it is a liquid.
