Abraham and Lot—A Story of Decoherence

So Abram went, as the Eternal had spoken unto him; and Lot went with him… And Abram took Sarai his wife, and Lot his brother’s son… (Genesis 12:4-5) And Abram went up out of Egypt, he, and his wife, and all that he had, and Lot with him, into the South. (Genesis 13:1) And Lot also, who went with Abram, had flocks, and herds, and tents. And the land was not able to bear them, that they might dwell together; for their substance was great, so that they could not dwell together. And there was a strife between the herdmen of Abram’s cattle and the herdmen of Lot’s cattle. And the Canaanite and the Perizzite dwelt then in the land. And Abram said unto Lot: ‘Let there be no strife, I pray thee, [...]

Abraham Meets Abraham From a Parallel Universe

And he [Abraham] lifted up his eyes and looked, and, lo, three men stood over against him…  (Genesis 18:2) On this blog, we often discuss the collapse of the wavefunction as the result of a measurement. This phenomenon is called the “measurement problem.” There are several reasons, for which the collapse of the wavefunction—part and parcel of the Copenhagen interpretation of quantum mechanics—is considered a problem. Firstly, it does not follow from the Schrödinger equation, the main equation of quantum mechanics that describes the evolution of the wavefunction in time, and is added ad hoc. Second, nobody knows how the collapse happens or how long the wave function takes to collapse. This is not even to consider that any notion that the collapse of the wavefunction is caused by human consciousness, as proposed [...]

Covenant between the Parts as a Metaphor for Quantum Entanglement

And he took him all these, and divided them in the midst, and laid each half over against the other… And it came to pass, that, when the sun was going down, a deep sleep fell upon Abram; and, lo, a dread, even a great darkness, fell upon him…  And it came to pass, that, when the sun went down, and there was thick darkness, behold a smoking furnace, and a flaming torch that passed between these pieces. Genesis 15:10-17 The above verses from the Torah portion Lech Lecha (Genesis 12:1–17:27) describe the Covenant between the Parts (a.k.a. the Covenant of the Pieces), when G‑d entered into eternal covenant with Abraham (at the time called Abram) – a covenant symbolized by halved animals. The simple meaning of this ritual is apparent: just as a halved [...]
