[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.
