<\/a><\/p>\n

Quantum mechanics, the most potent theory physicists have developed, doesn\u2019t make sense. What I mean by that statement is that quantum mechanics \u2014 which was developed to describe the microworld<\/a> of molecules, atoms, and subatomic particles \u2014 leaves its users without a common-sense picture of what it describes. Full of what seem to be paradoxes and puzzles, quantum physics demands, for most scientists, an interpretation: a way of making sense of its mathematical formalism in terms of a concrete description of what exists in the world and how we interact with it. Unfortunately, after a century not one but a basketful of \u201cquantum interpretations\u201d have been proposed. Which one is correct? Which one most clearly understands what quantum physics has been trying to tell us these past 100 years?<\/p>\n

In light of these questions, I\u2019m beginning a series that explores the most radical of all the quantum interpretations, the one I think gets it right, or at least is pointed in the right direction. It is a relative newcomer to the scene, so you may not have heard of it. But it has been gaining a lot of attention recently because it doesn\u2019t just ask us to reimagine how we view the science of atoms; it asks us to reimagine the process of science itself.<\/p>\n

The term \u201cQBism\u201d was shorthand for \u201cQuantum Bayesianism\u201d when this idea\/theory\/interpretation was first proposed in the late 1990s and early 2000s. The name hit the nail on the head because \u201cBayesianism\u201d is a radical way of interpreting probabilities<\/a>. The Bayesianist approach to what we mean by probability differs strongly from what you learned in school about coin flips and dice rolls and how frequently a particular result can be expected to appear. Since probabilities lie at the heart of quantum mechanics, QBism zeroed in on a key aspect of quantum formalism \u2014 one that other interpretations had missed or swept under the rug \u2014 because it focused squarely on how we interpret probabilities. We\u2019re going to dig deep into all of this as we go along in this series, but since today\u2019s column is supposed to be the introduction, let\u2019s start with a 10,000-foot view of what\u2019s at stake in the great \u201cQuantum Interpretation Wars\u201d so we can see where QBism fits in.<\/p>\n","protected":false},"excerpt":{"rendered":"
