A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

In materials science, "plastic" refers to the ability of a material to undergo permanent deformation under stress without breaking. Metals exhibit plasticity when they are subjected to stress beyond their elastic limit, allowing them to be shaped or formed. This property is distinct from the common use of the word "plastic" to describe synthetic polymers.

No. In astronomy, everything heavier than hydrogen or helium is referred to as metals. So, a star's metallicity would be including carbon, oxygen etc.

In my country we refer to gravel roads as metalled roads, for no reason I can explain.

"It's called blue metal since it has a blue colour."

That explains the blue, but not the metal...
