Breaking Symmetry to Inaugurate the Priests

The Torah portion Tzav describes a ritual performed by Moses in consecrating Aaron as the High Priest (Kohen Gadol) and his sons as priests (kohanim): And the other ram was presented, the ram of consecration, and Aaron and his sons laid their hands upon the head of the ram. And when it was slain, Moses took of the blood thereof, and put it upon the tip of Aaron’s right ear, and upon the thumb of his right hand, and upon the great toe of his right foot. And Aaron’s sons were brought, and Moses put of the blood upon the tip of their right ear, and upon the thumb of their right hand, and upon the great toe of their right foot; and Moses dashed the blood against the altar round about. Leviticus [...]

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 [...]

On Freedom of Choice, Divine Providence, and the Hard Problem of Philosophy

The story of Joseph and his brothers, described in the Torah portion of Vayeshev, presents many problems. Classical biblical commentators interpret the conflict between Joseph and his brothers in diametrically opposite ways. Some commentators interpret it literally—the brothers were guilty of conspiring to kill Joseph and, ultimately, selling him into slavery, for which they were held accountable.[1] In fact, the brothers admit their guilt: And they said one to another: ‘We are verily guilty concerning our brother, in that we saw the distress of his soul, when he besought us, and we would not hear. . . . Genesis 42:21 Others take the view that these events were predetermined by G‑d. Indeed, in the Covenant Between the Parts, G‑d reveals to Abraham that his descendants will be strangers in a foreign land. Furthermore, [...]

The Exclusion Principle

Like most Jewish families worldwide, last Shabbat, the conversation revolved around the situation in the Middle East and the war in Gaza. The question was, what is the end game? How will this war end after IDF destroys Hamas? The United States, no doubt, will push for the Two-State “solution.” But will such a solution be viable? My wife, Leah, ’שתחי, chimed in, “The two-state solution is not viable because the exclusion principle forbids it.” I immediately understood what she meant. It was a deep insight that captured the very essence of the problem. Leah was also trained as a physicist (in fact, we met at a physics conference). Although she specialized in biophysics, she is familiar with quantum mechanics and spoke to me in the language we both understood. What is the [...]

Israel’s Security Lapses as a Reflection of Lot Consciousness

The October 7th attack by Hamas terrorists on Israel was a double surprise. The brutality and barbarism of the attack, the unspeakable cruelty of the terrorists that stunned the civilized world, was shocking but hardly a surprise. The stunning failure of the Israeli intelligence services to anticipate the attack despite the writing on the wall was a surprise. The complete and shocking unpreparedness of the IDF, which took many hours to mount an organized response, after terrorists breached the security fence, killed many hundreds of civilians, and took many hostages, was another surprise. The Israeli intelligence was blissfully unaware of year-long preparations by Hamas and the Israeli army that was caught with its pants down, unprepared to defend Israel’s border with Gaza. The Torah describes three stages of the development of Mashiach consciousness. [...]

Sukkot and the Standard Model

And ye shall take you on the first day the fruit of goodly trees, branches of palm-trees, and boughs of thick trees, and willows of the brook. Leviticus 23:40 During the Holiday of Sukkot (“Tabernacles”), the Jewish people are commanded to take together four species (arba’a minim): etrog (fruit of a citron tree), lulav (a branch of a date palm), ḥadassim (boughs from the myrtle tree), and aravot (branches of the willow tree),[1] and hold them together while waving with them in all six directions (na’anuim). As I wrote in my essay “Unified Field Theory… Theory and Practice,”[2] the four species, arba’a minim, also correspond to the four letters of the Tetragrammaton. According to the Arizal, this relationship is as follows: Letter of the TetragrammatonArba’a MinimYudḤadassimHehAravotWawLulavHehEtrogTable 1. Letters of Tetragrammaton and Arba’a Minim As I wrote in my earlier essays,[3] all four fundamental forces correspond to the four [...]

Principle of Least Action — IV Lagrangian Mechanics

I agree, all its elegance notwithstanding, the principle of least action does not prove the existence of an intelligent Creator. In a sense, when it comes to inanimate matter, the hand of G‑d is concealed, preserving our freedom of choice—to believe or not to believe. However, when it comes to live matter, which, unlike passive inanimate matter, is actively pursuing the goals of survival and procreation, (locally) violating the second law of thermodynamics, there is no more choice. Acknowledging an intelligent Creator, who imbues live matter with goals it must labor to pursue, is no longer a matter of metaphysical commitments, it is a matter of intellectual honesty.

Principle of Least Action III — History

The spectacle of the universe becomes so much the grander, so much more beautiful, the worthier of its Author, when one knows that a small number of laws, most wisely established, suffice for all movements. Pierre Louis Maupertuis (1744) Among the more or less general laws, the discovery of which characterize the development of physical science during the last century, the principle of Least Action is at present certainly one which, by its form and comprehensiveness, may be said to have approached most closely to the ideal aim of theoretical inquiry. Its significance, properly understood, extends, not only to mechanical processes, but also to thermal and electrodynamic problems. In all the branches of science to which it applies, it gives, not only an explanation of certain characteristics of phenomena at present encountered, but [...]

Time as a Combination of Past and Future

Philosophers struggled with the notion of time from the dawn of human civilization. Physicists of today declared the problem of time the number one problem in theoretical physics. Jewish mysticism has much to say about time.[1] Rabbi Ḥayyim Vital, in the name of the Arizal, quotes a verse: בִּטְחוּ בַיהוָה עֲדֵי-עַד, כִּי בְּיָה יְהוָה צוּר עוֹלָמִים Isaiah 26:4 The standard English translation of this verse, by JPS is: Trust ye in the LORD for ever, for the LORD is GOD, an everlasting Rock. Isaiah 26:4 This is not a very good translation because it doesn't tell you what specific names of G-d are used in the pasuk. Let us spell out the names in this pasuk to see what is going on: Trust ye in Havyah (Y-H-W-H) for ever, for Kah (Y-H) is [...]

Metaphysics of Time in the Eyes of Philosophy and Kabbalah

A-Series and B-Series as Zman and Seder HaZmanim McTaggart’s series A and series B are two conceptual frameworks proposed by the philosopher J.M.E. McTaggart[1] to analyze the nature of time and its relationship to temporal properties such as past, present, and future. J. M. E. McTaggart, by Walter Stoneman, 1917 In McTaggart’s series A, also known as the “A-series” or the “temporal series,” time is understood in terms of the temporal properties of past, present, and future. The A-series categorizes events based on their temporal relations, such as past, present, and future, which are considered essential aspects of events. The A-series views time as a succession of moments where events move from the future, through the present, and into the past. It emphasizes the dynamic and changing nature of time, with events shifting their [...]

Tetragrammaton and the Standard Model

In the first installment of the Standard Model,[1] we uncovered a curious parallel between the arrangement of the elementary particles in the Standard Model (a.k.a. quantum field theory) and Seder Hishtalshelut—the chainlike ontological order of creation—a central doctrine of the Lurianic Kabbalah.[2] In this third installment, we will discover how the proper name of G‑d, the Tetragrammaton, is hard-wired in the standard model. In the Standard Model, all elementary particles are arranged in a four-by-four grid (with the addition of the Higgs Boson in some representations).[3] It is axiomatic in the Kabbalah that all things that are four are rooted in the four letters of the Tetragrammaton: yud (Y), heh (H), waw (W), and heh (H). In the first installment of the Standard Model, we showed that all elementary particles of the Standard [...]

The Fast of the Seventeenth of Tammuz as a Manifestation of Breaking of the Vessels of Tohu

Today, on the Seventeenth of Tammuz, Jewish people fast to commemorate several tragic events in Jewish history.[1] These tragic events include the breaking of the Tablets (Luchot) and the breach of the walls of Jerusalem twice—during the First and the Second Temple.[2] It seems that the confluence of these destructive events is not coincidental—all three are manifestations of the spiritual process called in Lurianic Kabbalah, Shevirat HaKelim (the “Breaking of the Vessels”).[3] Many readers may be surprised by the juxtaposition of historical events that happened in this physical world with primordial events that took place in another universe—Olam HaTohu (the “universe of Chaos”)[4] that preceded the creation of our universe—Olam HaTikkun (the “universe of Rectification”)[5] Indeed, how can something that happened before the creation of our universe can affect historical events in this [...]

Entrainment by the Red Heifer

And for the unclean they shall take of the ashes of the burning of the purification from sin, and running water shall be put thereto in a vessel. Numbers 19:17 In my essay “Paradox of the Red Heifer,” I proposed a mechanism by which the ashes of the red heifer remove the impurity of death, where I analogized the procedure with resuscitation using a defibrillator.[1] In this essay, I propose an additional mechanism based on the phenomenon of entrainment, which I will explain below. Entrainment In physics and biology, entrainment refers to the synchronization of two or more rhythmic cycles.[2] This concept can apply to various systems, from physical phenomena to biological rhythms. Here are a few examples: Physics. In mechanical systems, entrainment refers to the process whereby two interacting oscillating systems assume the [...]

The Standard Model II

In the first installment on the Standard Model, we uncovered a curious parallel between the arrangement of the elementary particles in the Standard Model (a.k.a. quantum field theory) and the biblical description of the encampment of the Jewish people in the wilderness of the Sinai Desert. We further demonstrated an even more surprising parallel between the standard model and Seder Hishtalshelut—the chainlike ontological order of creation—a central doctrine of the Lurianic Kabbalah. In this second installment, we will explore the difference between leptons (particles of matter) and bosons (quanta of fields) and discover an intuition for why bosons (except for Higgs) transcend space and time. Finally, we will find a spiritual parallel for the antimatter in the words of Ecclesiastes. Bosons vs Leptons—Transcending Space and Time The parallel between the four worlds on [...]

The Standard Model

Introduction What could the Standard Model of particle physics possibly have in common with biblical accounts of the Israelites’ travels in the Sinai Desert, Kabbalistic doctrines related to the unfolding of spiritual worlds, or the arrangement of the letters in the Name of G‑d? To make connections or parallels between such unrelated concepts may sound farfetched. However, this is exactly what we are going to do in this essay. Remember that in structural analysis, we do not concern ourselves with the specifics or the nature of the objects at hand—we are interested only in the interrelationships among the objects, the high-level structure, or the storyline. So, let us not worry that particle physics speaks of subatomic particles, whereas the Torah speaks of the arrangement of Jewish tribes around the Tabernacle in the desert—topics [...]
