[1]Haidinger's_brushlol we human can be so dumb. This is
  Haidinger's Brush.* Does this shape look familiar?* haven't you
  see it in different ways, expressed mathematically or in videos
  and pictures describing Quantum weirdness stuff, nature of
  light, polarization, magnetism, etc. etc.? Anyway, think about
  this: We're human.* We have biological limitations.* We use
  systems (like mathematics, science, measuring itself, and all
  the computers and other tools) that were BUILT by humans, FOR
  the use of humans. and no matter HOW SOPHISTICATED these
  measuring systems and tool become, we'll always run across: THIS
  The limitations of Objective Perception form this shape, like a
  window screen.* We don't notice the window screen unless we get
  REALLY REALLY close to it. Can we get past it?* Sure we can.*
  But it's a bias built into everything that's hard to shake
  because it's built into everything humans have made for our own
  use involving what we consider an objective view of reality.
