It Is Not Good For Man To Be Alone

And the Eternal G‑d said: “It is not good that the man should be alone; I will make him a helpmate opposite him.” (Genesis 2:18)   The end of this verse is rather puzzling. Why would the woman designated as a helpmate for Adam be opposite (literally “against”) him? One can perhaps soften things by translating the Hebrew eizer kenegdo as “counterpart.” However, in a literal translation, the question remains. A simple explanation is well known: if a man is worthy, his wife would be his best friend, ally, partner, companion, and helpmate. If the man is not worthy, however, his wife would be his opponent and antagonist. An esoteric interpretation offered by Rabbi Shneur Zalman of Liadi, in his commentary on this verse in “Torah Ohr,”[1] provides a deeper meaning. He writes [...]

Cosmology and the Tetragrammaton

As we discussed in the previous post “Singularity and Paradise,” Paradise offers a beautiful metaphor for modern cosmology wherein Eden is the initial singularity preceding the Big Bang, the river flowing from Eden to water the garden[1] is the expanding universe, and the garden itself is our planet Earth. This metaphor fits nicely with an old Kabbalistic allegory of a glassblower who maps the various stages of the glassblowing process with the four letters of the Tetragrammaton—Y‑H‑W‑H, or yud-heh-vav-heh. To create a glass object, the glassblower must first have a seminal idea of what he desires to create—this corresponds to the letter י (yud) of the Tetragrammaton, because yud represents Chokhmah, which itself represents the seminal idea and inspiration. Before the process of creation begins, the glassblower must inhale air into his lungs—this [...]

Singularity and Paradise

These are the chronicles of the heaven and of the earth when they were created, in the day that the Eternal G‑d made earth and heaven. (Genesis 2:4) The second chapter of Genesis contains many repetitions, the most famous of which is the second rendering of the story of the creation of Adam and Eve. The classical commentators explain that this chapter adds further details to the original story of creation told in chapter one. Indeed, the Torah itself makes it clear by stating that “these are chronicles of the heaven and the earth…” Thus, the biblical cosmology sketched out in the first chapter of Genesis is retold here in greater detail. *** And a river went out of Eden to water the garden. (Genesis 2:8-10) This verse positions Eden as the wellspring [...]

The Tree of Life and Wave Mechanics

As we discussed in the earlier post, The Tree of Knowledge as a Metaphor for Superposition of States and Heisenberg’s Uncertainty Principle, the Heisenberg uncertainty principle is a direct consequence of wave-particle duality. If so, shouldn’t we expect to see some hints at the wave nature of reality in the narrative of the Garden of Eden? And the Tree of Life (Etz HaChaim): what was it doing in Eden? It appears in the narrative only twice—in the very beginning and at the very end of the story of the primordial sin—almost as if to put a frame around the picture. At the start of this narrative, the verse states: And the Lord G‑d planted a garden eastward, in Eden; and there He put the man whom He had formed. And out of the ground [...]

Why the first humans were not allowed to eat from the Tree of Knowledge

As always in science, every answered question breeds new questions. Now that we understand that the Tree of Life and the Tree of Knowledge are metaphors for, respectively, the wave function and the collapse of the wave function (see my earlier post, "The Tree of Knowledge as a Metaphor for Superposition of States and Heisenberg’s Uncertainty Principle"), we are faced with more questions. Why did G‑d not want Adam and Eve to eat from the Tree of Knowledge? And what was so terrible about the forbidden fruit that eating it warranted capital punishment?[1] Let us recall that, according to our tradition, Adam and Eve were prohibited from eating from the Tree of Knowledge only for three hours. Adam and Eve were created on the sixth day—the Eve of the Sabbath (Erev Shabbat). With [...]

The Tree of Knowledge as a Metaphor for Superposition of States and Heisenberg’s Uncertainty Principle

And out of the ground made the Lord G‑d to grow every tree that is pleasant to the sight, and good for food; and the tree of life also in the midst of the garden, and the tree of the knowledge of good and evil. (Genesis 2:9) And the Lord G‑d commanded the man, saying: “Of every tree of the garden thou mayest freely eat; but of the tree of the knowledge of good and evil, thou shalt not eat of it; for in the day that thou eatest thereof thou shalt surely die.” (Genesis 2:16–17) Upon creating Adam and Eve, G‑d permitted them to eat any fruit from the Garden of Eden, except for the forbidden fruit—the fruit of the Tree of Knowledge. Disregarding this injunction, Adam and Eve ate the forbidden [...]

The Primacy of the Prime Numbers

And the messengers returned to Jacob, saying: “We came to thy brother Esau, and moreover he cometh to meet thee, and four hundred men with him.” (Genesis 32:7) On this blog, we primarily focus on structural parallels between Torah and Physics and, more specifically, quantum physics. Today I would like to explore an interesting parallel between this Torah portion and the number theory. In my previous essay on the Torah Portion Vayishlach, “Jacob Meets Esau and his 400 men,” I wrote “Esau and his 400 men together were 401 strong. 401 is a prime number that is the sum of seven consecutive prime numbers (43+47+53+59+61+67+71).” In that essay, I focused on the significance of the number seven. Let us now focus on the significance of the prime number. The structural parallel I see [...]

Three Angels: Past, Present, and Future

And the Lord appeared unto him in the plains of Mamre, as he sat in the entrance of the tent in the heat of the day; and he lifted up his eyes and looked, and, behold, three men stood over against him… (Genesis 18:1-2)   In the Torah portion Vayeira, three men appeared to Abraham as he was sitting at the entrance to his tent. The Talmud states that these three men were angels: Michael, Gabriel, and Rafael. Michael came to tell that Sarah will give birth to a son; Raphael came to heal Abraham after his circumcision; and Gabriel came to destroy Sodom. However, on a metaphorical level, it appears to me that these three angels personify three aspects of time: past, present, and future. Here are several clues that hint at [...]

Stress-testing the judgment

And Abraham drew near, and said: 'Wilt Thou indeed sweep away the righteous with the wicked? Perhaps there are fifty righteous within the city; wilt Thou indeed sweep away and not forgive the place for the fifty righteous that are therein? That be far from Thee to do after this manner, to slay the righteous with the wicked, that so the righteous should be as the wicked; that be far from Thee; shall not the Judge of all the earth do justly?' And the Lord said: 'If I find in Sodom fifty righteous within the city, then I will forgive all the place for their sake.' And Abraham answered and said: 'Behold now, I have taken upon me to speak unto the Lord, who am but dust and ashes. Perhaps there shall lack [...]

Noah’s Ark — Sailing through the Flood of Time

Time is a storm in which we are all lost. " (William Carlos Williams, Introduction to "Selected Essays") I always had a hard time relating to the story of the Flood on a literal level. Why would G‑d want to wipe out all people He created in full knowledge that they would sin? Like it was a surprise for G‑d! G‑d, who exists above time, which He created, cannot be surprised—He knows the future. Then why to create humanity, just to destroy it later? And animals. . . what was their fault? They have no freedom of choice. They act on instincts hardwired in their genome as they were created. Why punish them? Lots of questions, few answers. If the Torah says the flood happened, it must have happened. However, the Torah is [...]

Cosmic Symphony

Strings vibrate, Souls tremble, Angels are running and returning, G‑d is touching and not touching – The rhythms of the universe… Nothing stays still… all is in flux. The inexorable flow of time is synonymous with the existence itself. Indeed, everything exists in time. However, from where does the time come? This is, perhaps, the greatest mystery of science. In modern physics, we do not know what time is, let alone from where it comes. We only know how to measure it – by counting the number of periodic intervals, which we accept as a unit of time. For example, in antiquity, people used a night-day cycle as the basic unit of time. This cycle was born out of observations of the apparent rotation of the sun around the earth (although, in reality, [...]

Noah — the First Inventor

At the end of the first chapter of the Torah, Genesis (Bereshit), G‑d regrets, as it were, creating humanity that became depraved: And the Lord saw that the wickedness of man was great in the earth… And the Lord said: ‘I will blot out man whom I have created from the face of the earth…; for it repenteth Me that I have made them.’” (Gen. 6:5-7) Nevertheless, one man, Noah (Heb. Noach), found favor in the eyes of G‑d: But Noah found grace in the eyes of the Lord” (Gen. 6:8) We don’t learn about Noah’s righteousness until the following weekly Torah portion, Noach.  So, what did Noah do to find favor in the eyes of G‑d? The hint may be found in the earlier verse narrating Noah’s birth and his naming by [...]

Sukkot — Bringing Time into Space

Jews have a very strange custom to take four species (Heb. arba’a minim)—a fruit of a citron tree (etrog), a branch of a date palm (lulav), boughs from the myrtle tree (chadassim), and branches of the willow tree (aravot)—and wave them in all six directions (na’anuim) while holding the species together. The precise movements involve bringing the bunch to one’s heart, then moving them to and fro in all six directions, three in each direction, every time returning the bunch to the heart. A strange sight indeed… what could it possibly mean? I’ve written before that Sukkot has to do with bringing holiness into time and space. The seven days of dwelling in the sukkah-booth (a.k.a. tabernacle) is related to the most important cycle of time – 7: there are seven days in a week, seven years in a Sabbatical cycle (shemita), seven [...]

Chol Hamo’ed — Days in Superposition

Today is Chol Hamo’ed Sukkot – the intermediate days between the first and the last days of the holiday of Sukkot. These days are not quite holidays, but they are not ordinary days either. They are a strange hybrid or a mixture of a holiday and mundane days. In physics, we have a word for that – the state of superposition. I’ve written about it in my article Pesach Sheini – in a State of Superposition. Not to repeat myself, I refer the reader to that article for background information. In short, in physics, we speak of states of the system. Say, one state of a dreidel may be spinning clockwise. Another state would be spinning counterclockwise. These are pure states. In quantum mechanics, a system could be in a mixed state. Say, [...]

The Land We Married

And the Lord spoke unto Moses, saying: 'Command the children of Israel, and say unto them: When ye come into the land of Canaan, this shall be the land that shall fall unto you for an inheritance, even the land of Canaan according to the borders thereof.” (Numbers 34:1-2) And ye shall inherit the land by lot according to your families—to the more ye shall give the more inheritance, and to the fewer, thou shalt give the less inheritance; wheresoever the lot falleth to any man, that shall be his; according to the tribes of your fathers shall ye inherit.” (Numbers 33:54) And every daughter, that possesseth an inheritance in any tribe of the children of Israel, shall be wife unto one of the family of the tribe of her father, that the [...]

Daughters of Zelophehad

Then drew near the daughters of Zelophehad …. of the families of Manasseh, the son of Joseph; and these are the names of his daughters: Mahlah, Noah, and Hoglah, and Milcah, and Tirzah. And they stood before Moses and before Eleazar, the priest, and before the princes and all the congregation at the entrance to the Tent of Meeting, saying: “Our father died in the desert, …. and he had no sons. Why should our father's name be done away from among his family, because he had no son? Give unto us a possession among the brethren of our father.” (Numbers 27:1-4) In the Torah portion that was read last Shabbat in the Diaspora, Phineas (Pinchas), we read the story of the five daughters of Zelophehad who brought the claim for inheritance in [...]

Ẓiẓit, Koraḥ, and Wave-Particle Duality

The Lord spoke to Moses, saying: Speak to the children of Israel and you shall say to them that they shall make for themselves fringes [ẓiẓit] on the corners of their garments, throughout their generations, and they shall affix a thread of sky blue [wool] on the fringe of each corner. (Num. 15:37,38) They [Koraḥ and his men] assembled against Moses and Aaron, and said to them, “You take too much upon yourselves, for the entire congregation are all holy, and the Lord is in their midst. So why do you raise yourselves above the Lord's assembly” (Num. 16:3) The Torah portion Shelach deals primarily with the fiasco of the spies sent by Moses to scout out the land of Canaan. The portion ends, however, seemingly out of turn, with the commandment to [...]

Fitting Pieces of the Puzzle Together

Meditations on the Maaseh Merkavah – IV This is the fourth and the final installment in the series of posts related to Ezekiel’s prophesy, Ma’aseh Merkava, “The Making of the Chariot.” For background information, refer to the previous posts, “Space – Between Future and Past,” “Relational Space,” and “Collapse of the Wave Function.” Regular readers of my blog may be wondering about my last post “Futurist Interpretation of Quantum Mechanics,” which was about my new interpretation of quantum mechanics. This is not a physics blog, however; the Quantum Torah blog is about Torah and physics (or, more broadly, Torah and science). What did the last post have to do with Torah? Hopefully, it will all now become clear. Last Shavuot I had a very unusual experience. Sitting in shul listening to the reading [...]

Futurist Interpretation of Quantum Mechanics

(A popular summary of the paper “Towards Futuristic Interpretation of Quantum Mechanics” by Alexander Poltorak being currently prepared for publication) Quantum mechanics (QM) is one of the most successful theories of physics that withstood the test of time. Indeed, it is one of the best-tested theories known to science. Yet, we hardly advanced in our understanding of the meaning of QM since its inception almost a century ago. The indeterministic nature of the theory puts it at odds with both classical physics and our intuition, and continues to perplex physicists and philosophers of science today as it perplexed Einstein, who famously said, “G‑d does not play dice with the universe!” Superposition and entanglement seem to defy common sense and, yet, they have been confirmed experimentally time and again. The phenomenon known as the [...]

Collapse of the Wave Function

Meditations on the Maaseh Merkavah – III This is the third installment in the series of posts related to the Ezekiel’s prophesy, Maaseh Merkava, “The Making of the Chariot.” For background information, the reader is referred to my previous posts, “Space – Between Future and Past” and “ Relational Space.” As I wrote in the first post, “Space – Between Future and Past,” Sefirot line up against four letters of Tetragrammaton, Y‑H‑W‑H, as follows: Yud י Chokhmah, Abba Heh  ה Binah, Imma Waw  ו Six Lower Sephirot (Z”A) Heh  ה Malchut   The first two letters of the proper name of G‑d, Y‑H‑W‑H – Havayah, or Tetragrammaton – are י “Yud” (sometimes transliterated as "Yod") and ה “Heh” (sometimes transliterated as "Hey" or "He").  During the reading of the Ezekiel’s prophesy Maaseh Merkava [...]
