Sean Carroll in Preposterous Universe:
There are many mysteries surrounding quantum mechanics. To me, the biggest mysteries are why physicists haven’t yet agreed on a complete understanding of the theory, and even more why they mostly seem content not to try. This puzzling attitude has historical roots that go back to the Bohr-Einstein debates. Adam Becker, in his book What Is Real?, looks at this history, and discusses how physicists have shied away from the foundations of quantum mechanics in the subsequent years. We discuss why this has been the case, and talk about some of the stubborn iconoclasts who insisted on thinking about it anyway.
