I can go with that. I like the "angle" angle.
  Phase changing has my fascination as well. Things can exhibit
  entirely different behaviors depending on their level. I don't
  care for when it gets analogized to evolution because it's
  different from that. A phase change is akin to the behavior of
  crystals; geometrical patterns that "lock" in self-reinforcing
  relationships, strengthening each others position to stay right
  where they are, given internal energies vs external energies
  [temperature generally]

  I sometimes wonder if the elements behave as they do more as a
  result of their structure - which can change shape depending on
  temperature, pressure, etc.

  It would explain a lot about the ability for different elements
  to behave like each other under given structures.

  I don't have any ready examples; it's something I was looking
  into about two years ago and was researching the effects of an
  low element (helium? hydrogen? I don't remember) and how there
  were surprising properties that emerges under unique
  combinations of low temperature and high pressure that caused it
  to resemble something entirely unexpected.

  Darned if I can remember what though. It's frustrating having
  the mental images available on-tap without the corresponding
  language to go with it or at least a few references for further
  research. But I haven't looked into this in a while, so memory's
  fuzzy on the details. chirality - yeah. I worked for a
  pharmaceutical company for a few years and remember chirality
  from a molecular/patent level. The scientists there would take a
  working formula and they're hurry up as fast as they could to
  find an equivalent molecule of other-handedness that provided
  the same functionality in order to create a new brand and extend
  their profit margin for another 7 years or whatever.

  In my time it was Clartin --> Clartinex but I remember them
  doing others in that way.

  It's only somewhat related, in that the handedness of molecules
  is known but the handedness of things at a smaller/earlier times
  in history is less known.
