The Flood—a Quantum Metaphor

The Flood—a Quantum Metaphor

Noah’s flood was a cataclysmic event with no parallels in recorded history. All of humanity (along with flora and fauna)—except for Noah and his family (and the animals he took with him into the Ark)—was wiped off the face of the earth. Some may call this catastrophic event the Great Extinction, others, the Great Destruction, but I would call it the Great Collapse. If we focus not only on what the Torah says but also on what it tells us, we notice that the Deluge is a metaphor for the collapse of the wave function—the key concept in quantum mechanics. We often talked about the wave function collapse on this blog. However, for those who come here for the first time or feel they need a refresher, here is a very short summary [...]

The Tree of Knowledge as a Quantum-Mechanical Metaphor

The Tree of Knowledge as a Quantum-Mechanical Metaphor

To Mendel Almost three years ago, in December of 2019, I posted an essay, "The Tree of Knowledge as a Metaphor for Superposition of States and Heisenberg’s Uncertainty Principle." The manuscript of that essay contained an addendum with a short primer on the superposition of states in quantum mechanics and quantum-mechanical treatment of the primordial sin. It expressed the ideas of Maimonides about primordial sin in precise mathematical formulas proving the exact parallel between the fruit of the tree of knowledge of good and evil and a quantum eraser. Realizing that only people familiar with the formalism of quantum mechanics would understand that part of the essay and fearing losing my readers, I decided to omit the addendum entirely. However, the addendum is arguably the most interesting part of the essay, because it [...]

Curses, Blessings, and Semiconductors

Curses, Blessings, and Semiconductors

Ki Tavo And it shall come to pass, when the Lord thy God shall bring thee into the land whither thou goest to possess it, that thou shalt set the blessing upon mount Gerizim, and the curse upon mount Ebal. (Deuteronomy 11:29)These shall stand upon mount Gerizim to bless the people, when ye are passed over the Jordan: Simeon, and Levi, and Judah, and Issachar, and Joseph, and Benjamin; and these shall stand upon mount Ebal for the curse: Reuben, Gad, and Asher, and Zebulun, Dan, and Naphtali. And the Levites shall speak, and say unto all the men of Israel with a loud voice: Cursed be the man that maketh a graven or molten image, an abomination unto the LORD, the work of the hands of the craftsman, and setteth it up [...]

The Captive Beauty

In the proposed allegorical interpretation, the soldier in the war is a metaphor for the Jewish people, who are all “soldiers” in G‑d’s army Tzivot Hashem, who fight the battle against evil to liberate and elevate fallen sparks from Tohu; where the beautiful woman from another nation is a metaphor for a fallen spark from another universe (Tohu), where the uncontrollable attraction the soldier feels towards the beautiful captive is a metaphor for the uncontrollable attraction a Jewish person (who is attuned to spirituality) feels towards divine sparks he is destined to redeem; where after having extracted the fallen spark from the clutches of evil, it requires a period of purification to achieve the ultimate marriage—the reintegration of the fallen spark into the domain of holiness.

Zettaflood

In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.Genesis 7:11 As the Torah tells us, at the dawn of human history, the flood swept the world. Most people, except for Noah and his family, drowned in that flood. Today, we too are drowning in a flood of a different kind—the informational flood. To put the current flood in perspective, consider this: according to one estimate in 2003, between the beginning of human civilization and the spread of computers, humanity generated cumulatively about 12 exabytes (12x1018 bytes) of data. However, in 2002 alone, we generated 5 exabytes of data. According to another estimate, [...]

Fill the Earth

Fill the Earth

And G‑d created man in His own image, in the image of G‑d created He him; male and female created He them. And G‑d blessed them; and G‑d said unto them: “Be fruitful, and multiply, and replenish the earth, and subdue it . . . .Genesis 1:28 G‑d created man, male and female, and commanded them to be fruitful and multiply, fill the earth, and subdue or conquer it. While the literal meaning of this verse is apparent—fill the earth with your progeny by procreating[1]—it begs a question. Specifically, the phrase “fill the earth” seems superfluous—wasn’t it enough to say “Be fruitful and multiply”? Indeed, the Hebrew word milupim[2] (“to multiply”) is etymologically related to the word mil’u[3] (“to fill”).[4] If humans were to multiply, as commanded by G‑d, they would naturally fill the earth. It seems [...]

The Cosmological Problem of Initial Conditions and the Universe of Tohu

The Cosmological Problem of Initial Conditions and the Universe of Tohu

Now the earth was unformed and void.Genesis 1:2 We have a big problem in cosmology: the problem of the initial conditions of the universe at the time of the Big Bang.[1] Before we can explain this problem, however, we need to review some basic concepts of thermodynamics. Thermodynamics developed by Boltzmann and others[2] described the behavior of gases and liquids and the transfer of heat. A key concept in thermodynamics is entropy. Entropy is a measure of disorder, of chaos. The second law of thermodynamics states that in an isolated system, entropy always increases with time. The second law of thermodynamics explains universal decay. And entropy is the measure of that decay.[3] Shining stars produce entropy. Stars collapsing into black holes produce entropy. Evaporating black holes produce entropy.[4] Entropy is increasing in the universe.[5] Let us [...]

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 [...]

Joseph’s Birth—A View From Quantum Mechanics and Biology

Joseph’s Birth—A View From Quantum Mechanics and Biology

And afterwards she bore a daughter, and called her name Dinah. (Genesis 30:21) In my previous essay, “The Conflict Between Joseph And His Brothers—A Gender Theory,” I suggested that Joseph exhibited some proclivity to feminine behavior in his youth. This impression can be naturally inferred from the verses and supported by traditions in Kabbalah related to Isaac, Joseph, and Benjamin, as we discussed in that essay. To be sure, Joseph outgrew his feminine tendencies (perhaps assisted by the tough love shown to him by his brothers). He matured into a man who was not only a husband, a father, and the de facto ruler of Egypt, but an archetype of masculinity and a paradigm of piety, for which he earned the designation of Joseph, the Righteous (Yosef HaTzadik). Moreover, spiritually, Joseph personified Yesod [...]

The Conflict Between Joseph And His Brothers—A Gender Theory

The Conflict Between Joseph And His Brothers—A Gender Theory

The confrontation between Joseph and his brothers is one of the most troubling stories of the Bible. Joseph and his brother—twelve sons of Jacob—were the progenitors of the twelve tribes of Israel. They are described as tzadikim (the righteous and pious men) and prophets. However, as we read in the Torah portion Vayeshev, we are told that brothers hated Joseph: And when his brethren saw that their father loved him more than all his brethren, they hated him, and could not speak peaceably unto him. (Genesis 37:3) And Joseph dreamed a dream, and he told it to his brethren; and they hated him yet the more. (Genesis 37:5) And his brethren envied him… (Genesis 37:11) The brothers intended to kill Joseph: And they said one to another: ‘Behold, this dreamer cometh. Come now [...]

Jacob’s Struggle With a Man: A Metaphor From Neuroscience

Jacob’s Struggle With a Man: A Metaphor From Neuroscience

So the present passed over before him; and he himself lodged that night in the camp. And he rose up that night, and took his two wives, and his two handmaids, and his eleven children, and passed over the ford of the Jabbok. And he took them, and sent them over the stream, and sent over that which he had. And Jacob was left alone; and there wrestled a man with him until the breaking of the day. And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob’s thigh was strained, as he wrestled with him. And he said: “Let me go, for the day breaketh.” (Genesis 32:23–26) The story of Jacob wrestling with a “man” is yet another of [...]

On Rachel, Leah, and Dark Energy

On Rachel, Leah, and Dark Energy

Now Laban had two daughters: the name of the elder was Leah, and the name of the younger was Rachel. (Genesis 29:16) Rabbi Isaiah Horowitz (the Shelah HaKadosh)[1] famously says that the Torah speaks to the upper worlds and hints at the lower worlds. That means that the primary subject of the Torah narrative has to do with the dynamics of the spiritual worlds while only hinting at the historical narrative that appears to be the meaning of the biblical text. It is not surprising because what happens down here reflects what happens up there—in the spiritual spheres. However, the historical narrative is not necessarily the only reflection of the higher reality. We may see how the same or similar dynamic is reflected in natural laws. This Torah portion introduces us to two daughters [...]

Jacob and Esau—Thermodynamics of Order and Chaos

Jacob and Esau—Thermodynamics of Order and Chaos

And these are the chronicles of Isaac… (Genesis 25:19) So Esau went unto Ishmael, and took unto the wives that he had Mahalath the daughter of Ishmael Abraham’s son, the sister of Nebaioth, to be his wife. (Genesis 28:9) This Torah portion is called Toledot. In Hebrew, toledot means “generations” or “chronicles.” Indeed, this Torah portion starts with the phrase, “These are the chronicles of Isaac.” This is not the first or the last time this word appears in Tanakh (the Hebrew Scriptures). It appears for the first time in the opening verse of chapter 2 of Genesis: 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 time it appears in [...]

And Rebekah spoke unto Jacob, her son, saying: “Behold, I heard thy father speak unto Esau thy brother, saying: Bring me venison, and make me savoury food, that I may eat, and bless thee before the Eternal before my death. Now, therefore, my son, hearken to my voice according to that which I command thee. Go now to the flock, and fetch me from thence two good kids of the goats; and I will make them savoury food for thy father, such as he loveth; and thou shalt bring it to thy father, that he may eat, so that he may bless thee before his death.” And Jacob said to Rebekah his mother: “Behold, Esau my brother is a hairy man, and I am a smooth man.

Keturah and Hagar III—A Metaphor for Unification

Keturah and Hagar III—A Metaphor for Unification

And Abraham took another wife, and her name was Keturah. (Genesis 25:1) Keturah: This is Hagar. She was called Keturah because her deeds were as pleasant as keturah (incense). (Genesis Rabbah 61:5) Keturah is Hagar. (Zohar 133) As we discussed earlier, Abraham had a concubine, Hagar. Later in life, after the passing of Sarah, Abraham took another wife whose name was Keturah. Midrash, the Zohar, Rashi, and other commentators state that Keturah is Hagar. To distill this situation to its essence, we have here two seemingly distinct individuals who, in the view of at least some biblical commentators, are one and the same person. To any physicist, this narrative bespeaks a unification. Indeed, this situation is analogous to the unification tendency in theoretical physics, where different fundamental interactions are unified into one. [...]

Keturah—an Allegory of Entanglement

Keturah—an Allegory of Entanglement

And Abraham took another wife, and her name was Keturah (Genesis 25:1) As I discussed in the earlier essay, “Yom Kippur – Disentangling the Entangled,” Adam and Eve were entangled. They were not unique in this. I wrote in several essays that every married couple is entangled.[1] How do we know that? Adam and Eve were created as one unit—“Male and female He created them”—as conjoint (Siamese) twins. Although G‑d separated Eve from Adam, they remained entangled, just as two particles born from the decay of another particle remain entangled even after their separation. Thus, Adam and Eve’s entanglement cannot be proof that all married couples are entangled. However, the Torah states so explicitly: Therefore shall a man leave his father and his mother, and shall cleave unto his wife, and they [...]

The Circumcision—The Interference of Parallel Universes

This is My covenant, which ye shall keep, between Me and you and thy seed after thee: every male among you shall be circumcised. And ye shall be circumcised in the flesh of your foreskin; and it shall be a token of a covenant betwixt Me and you. And he that is eight days old shall be circumcised among you, every male throughout your generations. . . . and My covenant shall be in your flesh for an everlasting covenant. (Genesis 17:10–3) Sages tell us that Abraham and other patriarchs knew the Torah prophetically before it was given to the Jewish people on Mount Sinai some 364 years after the Akeida took place.[1] Moreover, sages tell us that Abraham “observed” all of the Torah commandments. However, Abraham’s observance of the Torah commandments [...]

Akeida in Parallel Universes

Akeida in Parallel Universes

Michael Frayn’s 1998 play, Copenhagen, concerns a meeting between two great physicists, Niels Bohr and Werner Heisenberg, in 1941 in Copenhagen. In this play, the spirits of Heisenberg, Bohr, and Bohr’s wife, Margrethe, come together in the afterlife to answer Margrethe’s question, “Why did Heisenberg come to Copenhagen?” Bohr and Heisenberg worked closely together in Copenhagen in the 1920s while developing atomic physics, resulting in the formulation of quantum mechanics. Bohr was already an accomplished scientist when the young German Heisenberg joined his group, and Bohr began mentoring him. Heisenberg became one of the leading figures in formulating the new quantum mechanics. Later, Heisenberg joined the group of German physicists developing nuclear weapons for Nazi Germany. Why did Heisenberg return to Copenhagen in 1941? Denmark was at that time already occupied by Germany. [...]
