Watching the Vsauce short The Only Element You Can Chew Like Gum I was intrigued by
This is indium, the only element in the universe that is safe, and soft enough to chew like bubble gum... it softened as it warmed up in my mouth and I could tell it was metal because I could feel the vibrations of the crystals twinning.
A question about the vibrations caused by dynamic Crystal twinning could be searched or asked under (for example, not necessarily exhaustive):
- metallurgy (163 questions) tag in Engineering SE
- metallurgy (179) and/or crystallography (269) tags in Chemistry SE
- crystals (941) and/or metals (507) tags in Physics SE
- crystallography (112) and/or grain-boundaries (4) in Matter Modeling SE
- crystals (32) and/or crystallography (38) and/or mineralogy (175) in Earth Science SE
Is there a way within Stack Exchange to flatten my searching for questions and answers about things related to phenomenon like crystallographic twinning in metals under deformation without going outside and using a search engine?
I am not saying that there's anything wrong with using a search engine! I'm just asking if there is also something internal and site-flattened.
