bhobba said:What I gave is the modern version of the Born rule I think formulated by Von-Neumann[ - it's also in Ballentine.
But I found that it is called so already by van Vraasen in 1950:A. Neumaier said:Thus what you call the modern version of Born's rule is actually Ballentine's postulate. He doesn't call it Born's rule.
B.C. van Fraassen,
The Representation of Nature in Physics: A Reflection On Adolf
Grünbaum's Early Writings,
Mechanics, 17 (1950), 26--34.
So it should probably be called van Vraasen's postulate, or van Vraasen's version of Born's rule.
