Pictures of space-time look misleadingly like pictures of space, and the novice must unlearn some of the conventions... - Tim Maudlin

[T]he experimental verification of Bell's inequality constitutes the most significant event of the last half-century. ...[O]ur basic picture of space, time, and physical reality must change. These results, and the mysteries they engender, should be the common property of all who contemplate with wonder the universe we inhabit.

[P]roblems about the fundamental consistency of our two fundamental physical theories may appear. ...It arises from the remarkable results derived by John Stewart Bell in 1964 ...[C]ertain pairs of particles that are governed by quantum laws... appear to remain "connected" or "in communication" no matter how distantly separated... [T]he connection exists even when the observations carried out occupy positions... which cannot be connected by light rays. The particles communicate faster than light.

Quantum theory... formalism... uses no more than linear algebra and vector spaces. ...A particularly nice and accessible presentation of the requisite mathematics can be found in 's Quantum Mechanics and Experience (1992, Ch. 2).
