Miracle of Chanukah—Seeing and not Collapsing

As I wrote in my post, Schrödinger  Menorah:  Burning  And  Not  Burning, the Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, explains the miracle of Chanukah as a paradox of the menorah (chanukiah or hanukkiah) burning and not burning, thereby embodying the absolute nature of G‑d, who is not limited by His infinity and combines all possibilities including the 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 the 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 [...]

Schrödinger Menorah: Burning and not Burning

The miracle of Chanukah revolves around a single-day-supply of olive oil burning for eight days during the rededication of the Holy Temple in Jerusalem (Bet HaMikdash), after Maccabees liberated Israel from the occupation by the Greco-Syrian Seleucid empire. Rabbi Menachem Mendel Schneerson There are countless explanations of the miracle of the oil lasting eight days. The Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson, 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 natural oil was burning and not burning at the same time. The Rebbe draws an analogy with [...]

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 nuclear 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 (the leading candidate is the string theory), Jews around the world are practicing this unification during the holiday of Sukkot. During Sukkot, we take [...]

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 [...]

Standing and Moving

According to the Saadia Gaon, these two Torah portions – Nitzavim and Vayelech – are really one portion, which sometimes is split into two.  In the language of Quantum Mechanics (QM), the two portions are entangled, in a manner of speech, and are described by the single "wavefunction."  Needless to say, this is not meant in a literal sense, as QM describes physical objects, whereas these biblical chapters are certainly not.  Nevertheless, taking poetic license, we can loosely say that these portions are entangled, i.e., they are really one.  Nitzavim and Vayelech, however, speak of the opposite themes – “nitzavim” connotes standing( lit., you stand), while “vayelech” connotes walking (lit., …and he walked). As much as it seems paradoxical at first, from the physicist’s point of view, it is not surprising at all.  Typically, [...]

Fractal Patterns in the Torah

In the Torah portion Emor (Leviticus 21:1–24:23), we are instructed to abstain from work every seventh day on Shabbat. Next week’s Torah portion, Behar, continues this theme and instructs us to abstain from agricultural work every seventh Sabbatical year, Shmita. And the Torah doesn’t stop there. It instructs us to count seven Shmitas and then observe a Jubilee, Yovel. Do you notice a pattern? Every seven days, every seven years, every seven Shmitas… Furthermore, the Midrash states the world will exist for seven thousand years with the seventh millennium being a thousand years of the kingdom of Mashiach (Messiah)—yom shekuloy Shabbat—one long Shabbat. A second-century sage, Rabbi Huniah ben HaKanah, interprets this Midrash to mean that the world will last seven Cosmic Shmitas, i.e., 49 thousand years (which, according to a prominent 13th–14th [...]

When was the World Created?

There is a dispute in the Talmud as to when the world was created. According to Rabbi Eliezer, the world was created in the month of Tishrei, the seventh month of the Jewish calendar when we celebrate the Jewish New Year, Rosh HaShanah. According to Rabbi Yehoshua, the world was created in the first month of the year, the month of Nisan (Talmud, tr. Rosh HaShanah, 10b). The Hassidic thought attempts to reconcile these opposite opinions, suggesting that both opinions are correct—the world was created in Nisan in thought, whereas in deed, it was created in Tishrei. The problem with this approach is that for halakhic (Jewish ritual law) purposes of calculating the Jewish calendar, the planets are deemed to have commenced their heavenly orbits in Nisan, not in Tishrei. How could planets that [...]

Relativity of Manna

This is the thing which the Lord hath commanded: Gather ye of it every man according to his eating; an omer a head, according to the number of your persons, shall ye take it, every man for them that are in his tent.' And the children of Israel did so, and gathered some more, some less. And when they did mete it with an omer, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating. (Exodus 16-18) In the desert, Jewish people were given manna—one omer[1] (Biblical measure) per member of the household. Rashi explains: Some gathered [too] much [manna] and some gathered [too] little, but when they came home, they measured with an omer, each one what he had [...]

Pesach Sheini – in a State of Superposition

There were men who were ritually unclean [because of contact with] a dead person, and therefore could not make the Passover sacrifice on that day. So they approached Moses and Aaron on that day. Those men said to him, "We are ritually unclean [because of contact] with a dead person; [but] why should we be excluded so as not to bring the offering of the Lord in its appointed time, with all the children of Israel? Moses said to them, "Wait, and I will hear what the Lord instructs concerning you." The Lord spoke to Moses saying: “Speak to the children of Israel saying, Any person who becomes unclean from [contact with] the dead, or is on a distant journey, whether among you or in future generations, he shall make a Passover sacrifice [...]

Yom Kippur – Disentangling the Entangled

When G‑d created the first humans, Adam and Eve (Chavah), He created them as one. And G‑d created man in His own image, in the image of G‑d created He him; male and female created He them. (Gen. 1:27) Actually, as Midrash Rabbah (Gen. VIII:1) explains, Adam and Eve were created as one being as Siamese twins—attached by their side.  When the story of the creation of Adam is repeated in the next chapter, it seems as a very different story: And the Lord G‑d caused a deep sleep to fall upon the man, and he slept; and He took one of his ribs, and closed up the place with flesh instead thereof. And the rib, which the Lord G‑d had taken from the man, made He a woman, and brought her unto the [...]
