A quote that appeared here on April 14, 2013

"I know what 'nothing' means." — Joan Didion

Dirac on the 4×4 matrices of an underlying nothingness —

"Corresponding to the four rows and columns,
the wave function ψ  must contain a variable
that takes on four values, in order that the matrices
shall be capable of being multiplied into it." 

— P. A. M. Dirac, Principles of Quantum Mechanics,
     Fourth Edition, Oxford University Press, 1958,
     page 257
