# Bell's theorem/Qed-her

## About Qed-her[edit | edit source]

The image of Qed-her was discovered while using the keyword "genie" to look for an open-source clip-art image on *Commons* to serve as the "observer" who mysteriously announces the ball's color in the remote suitcase. The disappointment in not finding a "conventional genie" disappeared when it was discovered that this Egyptian genie of the underworld is so "hidden" that one must visit Italian Wikipedia to find it (see Wikipedia:Qed-her to see if this genie is still hidden).

The "trick" of using only three observables in order to simplify the calculation was falsely attributed to the genie on the main page of this resource.^{[1]} The trick was more likely introduced by an online chat with v:User_talk:Gill110951 on the symmetries of Bell's inequality. To appreciate the genie's "trick", look at slide 7 of **this discussion**, where *six* variables are used: (X_{1},Y_{1},Z_{1},X_{2},Y_{2},Z_{2}). This trick allows us to use only three variables, and this simplifies the algebraic steps a bit.

#### Another website also uses Egyptian icons[edit | edit source]

After Qed-her was oncoroporated into this resource, another website was discovered that uses Egyptian icons. It claims to "disprove" Bell's theorem:

The following websites disagree:^{[2]}

- Scott Aaronson (blog)
- Richard Gill (Cornell University Archives: Quantum Physics)
- Florin Moldoveanu (Cornell University Archives: Quantum Physics)

#### On the quote concerning whether Bell's theorem is paradoxical[edit | edit source]

*Bell's theorem has no more business than sunsets and sunrises to be paradoxical*

Although he did not write these exact words, credit for this statement should probably go to Mermin, who was attempting to legitimize the view held by some physicists that the philosophical implications of Bell's theorem have been overstated.

## The weeping angles of Doctor Who[edit | edit source]

the weeping angel has not yet been observed on Wikiversity.]] In a delightful irony, an image of a weeping angel can be placed on Wikipedia, but not on Wikiversity, because the copyright renders the image unavailable on Commons:Main Page. I believe such an upload is possible on Wikiversity, but why bother?

Instead, the reader should be referred to Wikipedia:Weeping Angel#Quantum mechanics
