The EPR claim of an "all values" spread in the coordinate depends on an idealized absolute and exact measurement of $p$ with $Delta\; p\; =\; 0$. Since this is physically impossible, the claim of "no physical reality" can be negated.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "The EPR claim of an "all values" spread in the coordinate depends on an idealized absolute and exact measurement of $p$ with $Delta\; p\; =\; 0$. Since this is physically impossible, the claim of "no physical reality" can be negated." in the context of "in F. J. Duarte (2013), Quantum Optics for Engineers place: New York, publisher: CRC, ISBN: 978-1439888537" to mean that wisdom is timeless.
