“Yoder contacted me to tell us to lay off the surveillance—and this guy knows way more than he should. I think we can use this to our advantage. He’s agreed to talk with two of my people”

“Okay,” Levi said. “I understand why that would upset your husband. But do you really think that would be cause for him to be murdered?” Menachem cleared his throat. “My brother-in-law was a very righteous man. He felt it was his calling to bring the truth to the people. You need to realize that to him, what the paper was doing was a sin. I also heard plenty from him in the last year about this issue. He made it clear that even though the newspaper never lied, by ensuring certain things were never said in print, they molded the public narrative. It was a sin of omission.”

“But he confided something to me that he wasn’t yet prepared to put into print. In fact, he wasn’t sure if he ever would be. He was almost convinced that the company he was working for was purposefully trying to deceive its readers. To shape the narrative, if you will.” Levi frowned. “I don’t understand. Isn’t that a newspaper’s job? I see outlandish stuff in the papers all the time.” “That’s the editorial sections. My husband worked in what people in the trade like to call hard news. It should involve no opinions, just the facts. But Mendel was convinced that the management at the paper wasn’t interested in telling their millions of readers the truth.”

“Given a wavefunction , the Wigner function is a function over classical phase space, defined by (5.77) We want to think of this as something akin to a probability distribution over phase space. At first glance that seems unlikely because, as we’ve seen, there is a difference between quantum states whose properties are undetermined and classical probability that can be ascribed to ignorance. This is reflected in the fact that and so we can’t ascribe simultaneous values to both observables. And, indeed, it will turn out that it’s not possible to interpret as a classical probability distribution. Nonetheless, it gets close. Let’s look at some properties of the Wigner function. First, it is real. (This follows by taking the complex conjugate and changing variables to .) Second, if we integrate over momentum, and use the fact that , we have (5.78) But that’s rather nice: marginalising over momentum gives us , which we know is the probability distribution over position. Moreover, if we have a normalised wavefunction then we know that .”
