^U learn, i learn: After watching Eric thecarguy's video on
  engine basics, digesting it, sharing it, i stumbled across this
  video this morning. It shows an amazing display of all the basic
  parts of an engine coming together, then you watch it run in a
  way that would be difficult to do in real life. i'm working to
  get an appreciation for this everyday piece of human inginuity.
  What amazed me is that i was able to name an awful lot of the
  parts as they were coming together, 'ooh! that's the crankshaft
  - that's the dual overhead camshaft - that's the exhaust
  manifold - that's the valve springs'. Being ignorant for so long
  was inexcusable. it'll take time but i'm getting there. And i
  hope some of you are too. it's easy to be amazed by uncommon
  things -- but to be amazed at everyday things is something
  special.^
