Mishkan – a Metaphor for Quantum Reality, II

Continuing the theme of my last post, Mishkan – a Metaphor for Quantum Reality, the analogy between the Tabernacle (“Mishkan”) and quantum reality goes even deeper. The quantum world is best described today by the Quantum Field Theory. According to this theory, there are no particles, only fields. When we interact with a field, it manifests itself as a quantum of the field, which, to some extent, looks and behaves like a particle. For example, when we interact with an electromagnetic field, it manifests itself as a photon – a quantum of the electromagnetic field. An electron, according to the Quantum Field Theory, is not really a particle but a quantum of the electron field, which is a quantum field that is spread across the entire universe. This quantum is an excitation of [...]

Purim: Celebrating Randomness

The story of Purim, which we read in the Book of Esther, is a story about a righteous Jewish leader who held fast to his principles refusing to bow down to a rabid anti-Semite. It’s a story about a courageous Jewish queen, Esther, who saved her people risking her life. And yet, this holiday is not called by the name of Mordechai or Esther, it  is called Purim, because, as the Book of Esther informs us: For Haman the son of Hammedatha the Agagite, the adversary of all the Jews, had devised to destroy the Jews, and he cast the pur—that is the lot—to terrify them and destroy them… Therefore, they called these days Purim after the name pur. (Book of Esther, 9:24,26) This is odd because the casting of the lot (pur) [...]

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 [...]

Chanukah Menorah, Burning Bush and Sotah

As I wrote in my previous post, Schrödinger  Menorah:  Burning  And  Not  Burning, the Lubavitcher Rebbe explains the miracle of Chanukah as a paradox of the menorah burning and not burning, thereby embodying the absolute nature of God, who is not limited by His infinity but combines all possibilities including infinitude (ko’ach bli gvul) and the finitude (ko’ach hagvul). The notion of the menorah burning and not burning easily lends itself to be cast in terms of the quantum superposition of states of burning and not burning. I couldn’t help myself to call it a Schrödinger Menorah. There a couple of problems, however, with this idea. Firstly, as the Rebbe wrote in 1971 in a letter to the editor of the Journal of the Association of Orthodox Jewish Scientists, “The idea of miracles implies [...]

Schrödinger Menorah: Burning and not Burning

The miracle of Chanukah revolves around a single-day-supply of olive oil burning for eight days during rededication of the Holy Temple in Jerusalem (Bet HaMikdash), after Maccabees liberated Israel from the occupation by Seleucid empire. There are countless explanations of the miracle of the oil lasting eight days. The Lubavitcher Rebbe offers a unique explanation. The Rebbe dismisses any explanation of the miracle that relies on the miraculous nature of the oil itself. The Rebbe maintains that, to be kosher for the Menorah, the oil had to be natural olive oil, not some miraculous oil. According to the Rebbe, the miracle was that the natural oil was burning and not burning at the same time. The Rebbe draws an analogy with the dimensions of the Ark (Aron) in the Holy of Holies (Kodesh [...]

One-to-Many and Many-to-One

And he arrived upon the place and lodged there all night, because the sun was set; and he took from the stones of the place, and put them under his head, and lay down in that place to sleep. — Gen.28:11 And Jacob rose up early in the morning, and took the stone that he had put under his head, and set it up for a pillar, and poured oil upon the top of it. — Gen.28:18 Rashi notes that, before Jacob lies down to sleep, the verse speaks of the plurality of stones: “he took from the stones of that place, and put them under his head.” When Jacob wakes up, the verse suddenly switches from plural to singular mentioning only one stone: “and took the stone that he had put under [...]

Unified Field Theory… and Practice

Albert Einstein had a lifelong quest—to develop a unified field theory—the theory that would describe as a single field gravity and electromagnetism (just as Maxwell unified electric and magnetic fields in a single electromagnetic field). Alas, Einstein did not succeed in his quest. Today, the goal is even more ambitious—to unify all four known fundamental forces: gravity, electromagnetism, strong and weak forces in a single model, the so-called Theory of Everything. If the hypothetical fifth force will be confirmed, it will also need to be included in the Theory of Everything. While theoretical physicists around the world are busy working our various approaches to such Theory of Everything (which include inter alia string theory, loop quantum gravity, etc.), Jews around the world are practicing this unification during the holiday of Sukkot. During Sukkot, [...]

The Fifth Force – Epilog

This post is a continuation and the conclusion of the previous post, THE FIFTH FORCE. Aside from the connection with the last week’s Torah portion, Vayelech, there is also connection with and Aseret Yimei Teshuvah (Ten Days of Repentance) and Yom Kippur. When it comes to physics of fundamental forces, there are two unresolved problems: (i) unification of gravity with the other three fundamental forces (electromagnetic, strong and weak); and (ii) discovery of the fifth force. Both problems are related to repentance (teshuvah), which comes to sharp focus on the Ten Days of Repentance (Aseret Yimei Teshuvah) and Yom Kippur. Firstly, the word “teshuva” doesn’t mean “repentance”, it literally means “return” In Kabbalah tradition, the word TeShuVaH, is read as “ToShuV H” – return of the letter “heh”. It is talking about the [...]

The Fifth Force

“Now therefore write ye this song for you, and teach thou it the children of Israel.” Deut. 31:19 The four known fundamental forces are: gravitational force, electromagnetic force, strong (nuclear) force and weak (betta decay) force. Newton first described gravitational force in his famous universal law of gravity. Today, we use Einstein’s General Theory of Relativity to describe strong gravitation fields. Electromagnetism was described in the 19 c. by Faraday and Maxwell. Strong and week forces were discovered much later, in the second half of the 20 c. Since Albert Einstein started a search for a unified field theory, unsuccessfully trying to unify (describe by a single theory) gravity and electromagnetism, the quest for a unified field theory – the “Theory of Everything” – became the holy grail of theoretical physics. Strong and [...]

The End of Days II

This post is a continuation of the earlier post, The End of Days I. In this Torah Portion, Shemot, we read about the encounter between Moses and the Almighty at the Burning Bush. And the angel of the Lord appeared unto him (Moses) in a flame of fire out of the midst of a bush; and he looked, and, behold, the bush burned with fire, and the bush was not consumed… Moreover, He said: 'I am the God of thy father, the God of Abraham, the God of Isaac, and the God of Jacob.' And Moses hid his face; for he was afraid to look upon God. And the Lord said: 'I have surely seen the affliction of My people that are in Egypt, and have heard their cry by reason of their [...]
