Gazing at the Shekhinah

Gazing at the Shekhinah

In his commentary on this week’s Torah Portion, Yitro, Rabbi Chayim Vital, writing in the name of his teacher, the Ari-zal, states that Abel was punished for gazing at the Shekhinah—the divine presence.[1] But what relevance does this have to the Torah portion retelling the greatest event in Jewish history (and, indeed, the history of human civilization)—the Sinaitic epiphany—the giving of the Torah? This is the Torah portion, where we read the Ten Commandments. What is the relevance of the sin of Abel to the Ten Commandments? More generally, what is Abel’s connection to this Torah portion? That is easy to understand. The Torah portion Yitro starts with the story of Jethro (Yitro), Moses’s father-in-law, coming to Moses in the Sinai desert with his daughter—the wife of Moses—and her two children. Rabbi Chayim [...]

Time and Space as Emergent Phenomena — Abstract

The current Torah portion Beshalach tells about the splitting of the Sea of Reeds. As I discussed in my essay, “Collapse and Revelation,” the splitting of the sea is a metaphor for the collapse of the wave function in quantum mechanics. The Alter Rebbe, the Baal HaTanya, taught us to leiben min hatzait (“to live with the time,” that is, to leave with the current reading of the Torah). Maybe this is why, this week, when we read in the Torah portion Beshalach about the splitting of the sea, I finally understood where time comes from. This question haunted me for more than forty years. Finally, this week, I got it—time emerges through the interaction of consciousness with the universal wave function, causing the sequence of wave function collapses that we perceive as [...]

Sanctuaries in Space and Time

Sanctuaries in Space and Time

We are quite familiar with space—we move freely in space back and forth; we concur space on land and beyond; we reclaim land from sea; we turn deserts into gardens; we turn desolated space into sprawling cities. We are, on the other hand, helpless in the face of time. We cannot move freely in time. We can’t move back in time. We are swept forward in the inexorable flow of time. We do not understand time; we cannot change it. We are masters of land, but not of time. It is for this reason, when G‑d instructed Moses how to build a sanctuary for Himself, He could not have started with time—we would have not the faintest idea what it meant—a sanctuary of G‑d in time—let alone how to do it. That is why G‑d started with space, instructing Moses how to build the Mishkan—a Sanctuary in space—first. Only then He commanded Moses about Shabbat.

Collapse and Revelation

Collapse and Revelation

The collapse of the wave function is the process of revealing hidden possibilities. Reducing uncertainty reveals information. Until the wave function collapse, the system is in an uncertain state—the state of superposition. The measurement that causes the collapse of the wave function eliminates this uncertainty revealing the state of the system. The collapse occurs as the result of an experiment or observation. It is the discovery of the state of the system. The process of discovery—revelation—in the terminology of Kabbalah—is the process of revealing Alma d’Isgalya (Revealed World) from Alma d’Iskasya (Hidden World). This is why the splitting of the sea can be seen as an allegory of the collapse of the wave function.

Egyptian Exile as a Metaphor for Compactification in String Theory

Egyptian Exile as a Metaphor for Compactification in String Theory

And they made their lives bitter with hard service, in mortar and in brick…Exodus 1:14 On a literal level, the Egyptian exile (Galut Mitzrayim) is a story of the Jewish people’s enslavement in ancient Egypt, where they were forced to do hard labor making mortar and bricks, and building cities for the Pharaoh. On a deeper level, it is axiomatic in Jewish mysticism that suffering is usually a means to purify and rectify a sinner’s soul in this or past incarnation. It is also axiomatic that any sin damages the sinner’s soul and some supernal spiritual levels that obstruct the flow of the divine benefice into the world, impeding the blessing and, therefore, causing suffering to the sinner. Technically, it works as follows. When a sin committed below causes damage above, the resulting [...]

The Surrounding Light and the Penetrating Light

The Surrounding Light and the Penetrating Light

The Torah portion Vayakhel deals with the construction of the Mishkan, i.e., the “Tabernacle.” In Kabbalah, the Mishkan is viewed as a microcosm that represents a miniature model of the entire universe—both physical and spiritual. The Mishkan was comprised primarily of two categories of objects. The first category included the coverings that made up the roof and the walls surrounding the Mishkan. The second category included kelim—the objects inside the Mishkan. This is not the first time the description of the coverings and kelim appear in the Torah. In the Torah portion Teruma, G‑d gives Moses detailed instructions for the construction of the Mishkan. Interestingly, in Teruma, G‑d first speaks of the kelim and then of the coverings, whereas in Vayakhel, when Moses instructs the Jewish people, he reverses the order and first [...]

Ki Tisa Hints at the Coronavirus

Ki Tisa Hints at the Coronavirus

On the Eve of Shabbat, we received a government mailing containing documents that we were required to fill out and send back to the Census Bureau. The connection between the Census and the plague was not lost on me. The Torah portion we read last Shabbat, Ki Tisa. It begins with the story of the census: When you count the children of Israel according to their numbers, let each one give to the Lord an atonement for his soul when they are counted; then there will be no plague among them when they are counted.” (Exodus 30:12) This verse, linking the census with a plague, was uncanny in view of the COVID-19—Coronavirus pandemic—the modern-day plague, in the midst of which we find ourselves today. Interestingly, the word “count” in the verse above is [...]

Ye shall be disentangled… but not disengaged

In my post, “Ye Shall be Disentangled,” I suggested that the verse: “Ye shall be holy, for I, the Lord, your G‑d, am holy” (Levit. 19:2) may be interpreted as: “Ye shall be disentangled, for I, the Lord, your G‑d, am disentangled.” I supported this proposition with the quantum monogamy principle (a.k.a. monogamy of entanglement) according to which, if two objects are entangled, neither of them can also be entangled with a third object. Consequently, if we wish to be entangled with G‑d, we cannot also be entangled with the material world, as it would violate the monogamy principle. Thus, we must disentangle from the world, i.e., be holly. One may legitimately object to this interpretation because, in Judaism, we do not have monasteries; we do not have monks, we don't withdraw from [...]

Vectors, Spins, and Gender

Vectors, Spins, and Gender

Vectors, Spins, and Gender Speak to the children of Israel, and have them take for Me an offering; from every person whose heart inspires him to generosity, you shall take My offering. (Ex. 25:2) Every physics professor teaching physics 101 to freshmen spends the first lecture teaching vector algebra. Why vectors are so important? Because most quantities in mechanics (a branch of physics dealing with motion and forces) are vectors. A vector is a mathematical object that has a magnitude and a direction. For example, velocity is a vector – it shows not only how fast the object is moving, but also in what direction it is moving (it is different from “speed” which is an average velocity and is just a number). Similarly, acceleration is a vector, force is a vector, angular [...]

Half-Shekel – Metaphor for Entanglement

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

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 [...]

Relativity of Manna

Relativity of Manna

This is the thing which the Lord hath commanded: Gather ye of it every man according to his eating; an omer a head, according to the number of your persons, shall ye take it, every man for them that are in his tent.' And the children of Israel did so, and gathered some more, some less. And when they did mete it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating. (Exodus 16-18) In the desert, Jewish people were given manna—one omer[1] (Biblical measure) per member of the household. Rashi explains: Some gathered [too] much [manna] and some gathered [too] little, but when they came home, they measured with an omer, each one what he had [...]

Thou Shall Not Be a Flipper

Reading the Haftorah this Shabbat brought to mind scenes from the 2004 Republican National Convention in Madison Square Garden in New York City where attendees where waving pictures of John Kerry chanting “Flip-flop, flip-flop…” referring to Kerry’s ever changing position on the war in Iraq (“First I voted for it, before I voted against it”) and other political issues. Former Governor of New York State, George Pataki, said there, “This year, we will win one for the Gipper, and they will lose one with the Flipper.” Kerry lost, as flippers usually do. This Haftorah (weekly portion of Prophets read publicly in Synagogues) starts with an astonishing statement of Elyahy Hanavi (Elijah the Prophet), “How long will you waver between two ideas? If the Lord is G‑d, follow Him, and if the Baal, follow him.” (Melachim-I [...]

Global or Local?

And let them make me a Sanctuary that I may dwell among them (Ex. 25:8) In modern physics, there are two paradigms usually expressed as locality and nonlocality. Theoretical physics was born when Isaac Newton published his Philosophiæ Naturalis Principia Mathematica in 1687, where he formulated his laws of motion and the universal law of gravity. The law of gravity says that two masses attract each other proportionally to the product of their masses and inversely proportionally to the square of the distance between them. This law said nothing about the nature of the gravitational interaction, it did not explain the mechanism of this attraction at a distance. Newton was bothered by the question of how one body can act on another body far removed from it with nothing in between, i.e., the notion of “action [...]

Convergence of Science and Torah

Convergence of Science and Torah

The Torah portion of Yitro (Ex. 18), is the high point of the story of Exodus—the giving of the Decalogue on Mount Sinai. In a strange digression, the progressive narrative of the Exodus from Egypt is interrupted by the side story of Jethro (Yitro), the father-in-law of Moses, who comes to Sinai desert to join the Jewish nation. After hearing Moses’ account of all the miracles G‑d performed for Jewish people, Jethro exclaimed: Now I know that the Lord is greater than all deities. (Ex. 18:11) Jethro said confidently, “I know,” because, as the chief priest of Midian, he indeed knew all pagan cults and all deities worshiped in his time. Moreover, in antiquity, priests were expected to possess all secular knowledge as well (sadly, it is no longer the case). They needed to [...]

Manna – Superposition of All Tastes

While traveling in the Sinai desert, Israelites were fed by the heavenly bread – the manna. The Torah portions – parshat Beshalach – states that raw manna tasted like wafers that had been made with honey: וַיִּקְרְאוּ בֵית-יִשְׂרָאֵל אֶת-שְׁמוֹ, מָן; וְהוּא, כְּזֶרַע גַּד לָבָן, וְטַעְמוֹ, כְּצַפִּיחִת בִּדְבָשׁ. And the house of Israel called the name thereof Manna; and it was like coriander seed, white; and the taste of it was like wafers made with honey. (Ex. 16:31): However, in Numbers, it says that it tasted like cakes baked with oil: כְּטַעַם לְשַׁד הַשָּׁמֶן The taste of it was as the taste of a cake baked with oil. (Num. 11:8) The Talmud (Yoma 75b) reconciles this discrepancy by explaining that the tastes varied depending who ate the manna – to small children it tasted [...]

Splitting of the Sea

Do you like riddles? Here is a riddle – what do these two figures represent in the context of Exodus? No Idea? How about a hint? Still no idea? Okay, here is the answer: Yes, the first figure represents two doorposts and the lintel marked with the blood of Passover sacrifice, as it says: וְלָקְחוּ, מִן-הַדָּם, וְנָתְנוּ עַל-שְׁתֵּי הַמְּזוּזֹת, וְעַל-הַמַּשְׁקוֹף--עַל, הַבָּתִּים, אֲשֶׁר-יֹאכְלוּ אֹתוֹ, בָּהֶם And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it. (Ex. 12:7) The second picture is of the splitting of the sea, as it says: וַיָּבֹאוּ בְנֵי-יִשְׂרָאֵל בְּתוֹךְ הַיָּם, בַּיַּבָּשָׁה; וְהַמַּיִם לָהֶם חוֹמָה, מִימִינָם וּמִשְּׂמֹאלָם And the children of Israel went into the midst of the sea upon the dry ground; and the [...]

And the answer is... (drum roll, please) Yes, the first figure represents two doorposts and the lintel marked with blood of Passover sacrifice and circumcisions as is says: וְלָקְחוּ, מִן-הַדָּם, וְנָתְנוּ עַל-שְׁתֵּי הַמְּזוּזֹת, וְעַל-הַמַּשְׁקוֹף--עַל, הַבָּתִּים, אֲשֶׁר-יֹאכְלוּ אֹתוֹ, בָּהֶם And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it.
