The "smear" is what makes it work. What's in the middle of the
  electron that makes it different from the outer surface of the
  electron? There's no middle of the electron and there's no outer
  surface of an electron. It's the quantum physics equivalent of,
  "What existed before God?" from our human theological past:
  There's no before, before. In an electron, there's no there,
  there. In both cases, it's one of those, omg-woah-mind-blown
  things when it clicks in... one from the world of theology and
  one from the world of QM. [not asserting God but rather a
  similar experience to the thinker] === I love the omg-woah
  moments when trying to understand concepts. I remember my
  omg-woah moment as a kid in Sunday school and I remember my
  omg-woah moment when I was first trying to 'get' black holes in
  high school (a year before Hawking's book too. He had a sightly
  different take on things than I got... the hard way.. going
  through encyclopedias... ugh. His book would've made it easier)
  Black holes helped me 'get' Einstein. I particularly loved the
  Einstein-Rosen bridge thing. It was the gravity thing.
  Theoretical black holes helped me 'get' electrons vs classical
  mechanics: I could treat electrons in the same way I would treat
  the center of gravity of a theoretical black hole: It's just a
  thing. There's no inside of the center of gravity nor is there
  an outside of the center of gravity. You've at the 'it'. The
  'point'. Electrons to me were similar to centers of gravity in
  that you had to treat it as a point: there simply WAS no further
  in to go. It is what it is, it does what it does, and that's
  that. No further peeking allowed or possible. Buck stops here.
  No where else to go. smile emoticon Of course I still want to go
  further and in my mind, I do smile emoticon == Now, I don't know
  if he has the reference in your edition [1]Jes Scott - but in
  the edition I downloaded, he gives a reference to an obscure
  paper offering an _alternative_ viewpoint + treatment of Spin.
  It's from 1986 and HE bases it upon an equally obscure work done
  in 1939, a point at which such an idea would also have been
  unpopular. For your perusal:
