Half-Shekel – Metaphor for Entanglement
This they shall give, everyone who goes through the counting: half a shekel according to the holy shekel. Twenty gerahs equal one shekel; half of a shekel shall be an offering to the Lord Ex. 30:13 In this week’s Torah portion, Ki Tisa (Ex. 30), Jewish people are given the commandment of donating a coin as atonement, not just a coin – half a coin. But why half? If G‑d thought, twenty gerahs would be too much, He could have commanded Moses to mint another coin worth ten gerahs. But no, the coin was to remain what it was—worth twenty gerahs—and Jews were to give half a coin. Don’t you find it peculiar? I don’t, because half-coins are the favorite metaphor for explaining quantum entanglement. What is entanglement? When obtaining information about one [...]
Sacrifices and incenses – fields and entanglement
At the end of the weekly portion, Tetzaveh, the Torah speaks of the burnt offerings (Heb. qorbanot) and the incense offerings (Heb. qetoret). The Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, contrasts these two types of offerings by highlighting their symbolism. The Hebrew word for a burnt offering or sacrifice, qorban, is etymologically related to the word qarov “close,” qiruv “to bring close” and qerovim “relatives,” as they all share the same root QRB “to be close.” Sacrificial offering (qorban) meant to bring a person who brought it close (qarov) to G‑d. The Hebrew word for incense offerings, qetoret, literally means “smoke," "the odor of sacrifice," or "incense.” However, Rabbi David Kimchi ("Radak") points out that the word qeturot means “connected” as it is etymologically related to the Aramaic word qeter “to bind” and [...]
Entangled Cherubs
And thou shalt make two cherubim of gold; of beaten work shalt thou make them, at the two ends of the ark-cover. And make one cherub at the one end, and one cherub at the other end; of one piece with the ark-cover shall ye make the cherubim of the two ends thereof. And the cherubim shall spread out their wings on high, screening the ark-cover with their wings, with their faces one to another; toward the ark-cover shall the faces of the cherubim be. And thou shalt put the ark-cover above upon the ark; and in the ark thou shalt put the testimony that I shall give thee. And there I will meet with thee, and I will speak with thee from above the ark-cover, from between the two cherubim which are [...]
Standing and Moving
According to the Saadia Gaon, these two Torah portions – Nitzavim and Vayelech – are really one portion, which sometimes is split into two. In the language of Quantum Mechanics (QM), the two portions are entangled, in a manner of speech, and are described by the single "wavefunction." Needless to say, this is not meant in a literal sense, as QM describes physical objects, whereas these biblical chapters are certainly not. Nevertheless, taking poetic license, we can loosely say that these portions are entangled, i.e., they are really one. Nitzavim and Vayelech, however, speak of the opposite themes – “nitzavim” connotes standing( lit., you stand), while “vayelech” connotes walking (lit., …and he walked). As much as it seems paradoxical at first, from the physicist’s point of view, it is not surprising at all. Typically, [...]
Balak and Balaam – an entangled pair
In my last year’s post "Balak – Interference of Souls," I suggested that Balak needed Balaam (Bilam) to cause constructive interference to make the curse more powerful. This year, while reading this Torah portion last Shabbat, I realized that there was another reason for which Balak needed Balaam – the entanglement. As I wrote last year, both Balak and Balaam received evil aspects of the souls of Cain and Abel (Havel) but in different proportions: Balak was primarily a reincarnation (gilgul) of the evil aspect of Cain (although he also received some smaller portion of the evil aspect of the soul of Abel) and Balaam was primarily a reincarnation of the evil aspect of Abel (although he also received some smaller portion of the evil aspect of the soul of Cain). Let us [...]
Blessings and Curses of Entanglement
The blessings and the admonitions of Bechukotai (Leviticus 26:3–27:34) are viewed as the result of entanglement and disentanglement with G‑d respectively.
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 [...]
Balak – Interference of Souls
Balak the son of Zippor saw all that Israel had done to the Amorites. Moab became terrified of the people, for they were numerous, and Moab became disgusted because of the children of Israel. Moab said to the elders of Midian, "Now this assembly will eat up everything around us, as the ox eats up the greens of the field. Balak the son of Zippor was king of Moab at that time. He sent messengers to Balaam the son of Beor, to Pethor, which is by the river of the land of his people, to call for him, saying, "A people has come out of Egypt, and behold, they have covered the 'eye' of the land, and they are stationed opposite me. So now, please come and curse this people for me, for [...]
Suspected Adulteress as a Schrödinger Cat
In quantum mechanics, the state of a physical system is described by the so-called wave function (or the "wavefunction"). All attempts by Schrödinger, who first introduced the wave function, and others to interpret it as a scalar potential of some physical field, or as the de Broglie wave (as in particle-wave dualism) were not successful. In 1926, Max Born noticed that the squared amplitude of the wavefunction of a particle in a given region gives the probability of finding the particle in this region. He suggested that the wavefunction represented not a physical reality but rather our knowledge of the quantum state of an object. The wave function represents our knowledge of all possible quantum-mechanical states of an object and their probabilities. In other words, the quantum-mechanical state of a physical system is [...]
