+## Born's Rule
+=> https://www.quantamagazine.org/the-born-rule-has-been-derived-from-simple-physical-principles-20190213/ Quanta article on Born's rule
+> The problem is that Born’s rule was not really more than a smart guess — there was no fundamental reason that led Born to propose it. “It was an intuition without a precise justification,” said Adán Cabello, a quantum theorist at the University of Seville in Spain. “But it worked.” And yet for the past 90 years and more, no one has been able to explain why.
+> Born’s probability postulate is where the puzzle really is. [..] If we could understand where the Born rule comes from, we might finally understand what the vexed concept of measurement really means in quantum theory.
