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 each 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 [...]

Tzitzit, Korach, 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 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 [Korach 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 Shlach, which we read last Shabbat, 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 [...]

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, “God 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, YHWH, 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 God, YHWH – 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 [...]

Relational Space

Meditations on the Maaseh Merkavah – II This post is a sequel to my previous post, “Space – Between Future and Past.” For background information, the reader is referred to that post. My second Shavuot “epiphany” was that space is relational. Not that I realized that space was relational for the first time – I always thought so. But, for some reason, thinking about the meaning of the four faces of Chayot, the "living creatures" – the angelic beings described in the prophecy of Ezekiel that we read on Shavuot – made it absolutely clear in my mind. Isaac Newton The debate about the nature of space goes back at least to the times of Newton and Leibniz. Isaac Newton believed (as it is apparent from his mechanics and as it [...]

Space – Between Future and Past

Meditations on the Maaseh Merkavah – I We do science by studying nature. We study physics in a lab, peering into space, or working out mathematical models with pencil and paper to see if they fit experimental data. However, great mystics of the past were able to see how this world operates by gazing into spiritual worlds above. On Shavuot, the holiday when we celebrate the revelation on Mount Sinai, we read the prophecy of Ezekiel (the First Vision of Ezekiel) called Maaseh Merkavah (or Ma'aseh Merkabah) – Work of the Chariot. Masters of Kabbalah have taught us that understanding the Work of the Chariot gives the initiated an understanding of the works of nature. This Shavuot, studying and thinking about Maaseh Merkavah, I came to understand some profound insights about the physics [...]
