"complementarity is the realization that the behaviour of a particle and a wave, although they exclude each other, are both necessary for a complete description of all phenomena"
although the above quote is from werner heisenberg the wave/particle duality of particles was first spotted by neils bohr
complementarity was first used to describe the behaviour of waves and particles
this website takes the concept of complimentatarity and uses space/position as a conjugate to tie together nothing and something (nowhere and somewhere)
complimentarity can also be thought of in terms of the infinitely big and the infiinitely small
or as shapelessness and shape or...
