Adultery and Monogamy of Entanglement

And whosoever lieth carnally with a woman, that is a bondmaid, designated for a man, and not at all redeemed, nor was freedom given her; there shall be inquisition; they shall not be put to death, because she was not free. (Lev. 19:20) In Quantum physics there is a principle of monogamy of entanglement, which roughly means that if two particles (or objects) are entangled, neither can be entangled with a third particle (or object). A human parallel to this principle is obvious – if two spouses are married, neither can have any intimate relations with a third person. In other words, a marriage must be monogamous. It is because of this parallel that the physical relationship between entangled particles in quantum mechanics was named the monogamy principle, or monogamy of entanglement. In [...]

Ye shall be disentangled… but not disengaged

In my post, “Ye Shall be Disentangled,” I suggested that the verse: “Ye shall be holy, for I, the Lord, your God, am holy” (Levit. 19:2) may be interpreted as: “Ye shall be disentangled, for I, the Lord, your God, am disentangled.” I supported this proposition with the quantum monogamy principle (a.k.a. monogamy of entanglement) according to which, if two objects are entangled, neither of them can also be entangled with a third object. Consequently, if we wish to be entangled with God, we cannot also be entangled with the material world, as it would violate the monogamy principle. Thus, we must disentangle from the world, i.e., be holly. One may legitimately object to this interpretation because, in Judaism, we do not have monasteries; we do not have monks, we don't withdraw from [...]

The Puzzle of Pi

March 14 is celebrated by nerds around the world as the Pi Day. When written in digits, 3/14 represents first three digits of the number traditionally represented by the Greek letter “π” (pronounced pi) – 3.14. Pi Day is celebrated by eating pie and discussing the significance of π. Some folks who have too much time on their hands compete at memorizing decimal digits representing the value of pi. The record presently stands at 67,890 digits! While eating pie is optional, discussing the significance of π is truly mandatory. So, what is π and why is to so important? π is arguably the most famous mathematical constant, expressing the ratio between the circumference of a circle and its diameter. If you take a circle with a diameter of 1, the circumference of this [...]

Vectors, Spins, and Gender

Vectors, Spins, and Gender Speak to the children of Israel, and have them take for Me an offering; from every person whose heart inspires him to generosity, you shall take My offering. (Ex. 25:2) Every physics professor teaching physics 101 to freshmen spends the first lecture teaching vector algebra. Why vectors are so important? Because most quantities in mechanics (a branch of physics dealing with motion and forces) are vectors. A vector is a mathematical object that has a magnitude and a direction. For example, velocity is a vector – it shows not only how fast the object is moving, but also in what direction it is moving (it is different from “speed” which is an average velocity and is just a number). Similarly, acceleration is a vector, force is a vector, angular [...]

Fractal Tu B’Shevat

When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by wielding an axe against them; for thou mayest eat of them, but thou shalt not cut them down; for is the tree of the field man, that it should be besieged of thee? (Deut. 20:19) On Tu B’Shevat we celebrate the New Year of the trees. There is much to be said about the legal, ecological, homiletical, and mystical meaning of this day. And, indeed, much has been written about this minor holiday from these perspectives. In this post, however, I’d like to focus on the mathematical and biological aspects of this holiday that, to my knowledge, had not been discussed until now. When the Torah rhetorically asks, [...]

Chanukah Menorah – the River of Time

In a Kabbalistic meditation on lighting Chanukah Menorah, the Arizal links the menorah lights with a supernal river (see Candle on the River). The Arizal’s principal disciple, Rabbi Chaim Vital, writes in Shaar HaKavanot, Inyan Chanukah: One should meditate on the idea that the initials of the words ‘…l'hadleek ner Chanukah [to light the Chanukah candle]’ are the holy name called ‘Nachal’.” It is easy to see that the first letters of  “l'hadleek ner Chanukah” are three letters, Lamed (L), Nun (N), and Chet (Ch). Rearranged, these letters spell the word NaChaL – a stream or a small river. As I wrote in my essay “On the Nature of Time and the Age of the Universe” and more recently in the post “Joseph—the Master of Time,” a river has been the metaphor for time across many cultures. Does [...]

The Meaning of Life as Taught by Bayesian Angels

And he [Jacob] dreamed, and behold! a ladder set up on the ground and its top reached to heaven; and behold, angels of God were ascending and descending upon it. (Gen. 28:12) Rabbi Shneur Zalman of Liadi (a.k.a Baal HaTanya, or the Alter Rebbe) once remarked in Yiddish, “lieben mit di tzait” – live with the time, meaning one should live with Torah portion of the week.  Last week I was taught a lesson on how the current Torah portion affects my thinking, whether I know it or not. Last week I shared with my wife, who is a biophysicist, that while thinking about system biology, I realized that all organisms – from a single cell to multicellular organisms – are Bayesian systems. I knew that the brain is a Bayesian engine, but [...]
