The glass is neither half full nor half empty, it is a superposition of a states that is half full and half empty. If you randomly measured the liquid in the glass, half the time you will find that the glass is half full and other half of the time you will find that the glass is half empty – and that is the MOST accurate what to describe the above scenario.
Also, in case you are wondering what happened to the half of the liquid in this glass – yup, you guessed it, the Schrodinger’s cat licked it.
The glass is twice as big as it needs to be.
Good call Mike! Someone needs to talk to the guys producing these glasses – they could save a fortune in material costs by only producing the bottom half of the glass.
Why the negative sign between the wave functions? Couldn’t it be Psi-full plus Psi-empty?
