Information Asymmetry as a Cause of Antivaxxer Movement

It’s easy to blame anti-vaxxers. But should we? They come from a good place – they want to protect their children. As parents, we make many mistakes – all in the name of love for our children. Some of us are over-protective, some too strict, others too permissive. Most parents try to mold their children in their own image instead of allowing children to make their own choices and pursue their own talents and passions in life. Parental love is often misguided. However, refusing to vaccinate your children may be one of the most dangerous mistakes parents can make. Many suggested that anti-vaccination movements thrive on conspiracy theories. We find them on the right and on the left extremes of the political spectrum – those on the right mistrust the government, those on [...]

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 G‑d, am holy” (Levit. 19:2) may be interpreted as: “Ye shall be disentangled, for I, the Lord, your G‑d, 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 G‑d, 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 [...]

Wigner’s Friend Paradox

Amicus est Socrates, magister meus, sed magis est amica veritas. “Socrates is my friend but a greater friend is truth” – Plato c. 428-348 BCE. Amicus Plato, sed magis amica veritas. “Plato is my friend, but a greater friend is truth" – Aristotle, Nicomachean Ethics, 350 BCE. Amicus Plato amicus Aristoteles magis amica veritas. “Plato is my friend, Aristotle is my friend, but a greater friend is truth.” – Isaac Newton, Cambridge Student Notebook, 1661 You are my friend, but what is truth? – Eugene Wigner, 1961 If Isaac Newton summed up the aphorisms of Plato and Aristotle in his student notebook, exactly 300 years later, Eugene Wigner put this notion on its head. Although taking a poetic license, I put Wigner's words above in quotation marks, I do not know if he [...]

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, [...]

About Midnight

And Moses said: “Thus saith the Lord: About midnight will I go out into the midst of Egypt; and all the first-born in the land of Egypt shall die, from the first-born of Pharaoh that sitteth upon his throne, even unto the first-born of the maid-servant that is behind the mill; and all the first-born of cattle.  (Ex. 11:4-6) In the original verse, in Hebrew, Moses uses an unusual expression “k’hatzot halayalah.” The normal way of saying would be, “hatzot halailah” – at the midnight. (in Heb. laila means “night,” and hatzot means “the middle,” i.e., the middle of the night, or midnight.) However, the verse says, “k’hatzot halayalah.” Every commentator struggles with the addition of “k” before “hatzot.” Grammatically, the prefix “k” in Heb. is called kaf hadimiyan and signifies a likeness or [...]

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: 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."Shaar HaKavanot, Inyan Chanukah The first letters of the words  “l'hadleek ner Chanukah” are three letters, Lamed (L), Nun (N), and Chet (Ch). Rearranged, these letters spell the word NaChaL, that is, a stream or a small river. As I wrote in my essays, “On the Nature of Time and the Age of the Universe,” and “Joseph—the Master of Time,” a river has been the metaphor for time across many cultures. Does this Kabbalistic meditation hints at a connection between Chanukah lights and [...]

Jacob Meets Esau and His 400 Men

And the messengers returned to Jacob, saying: “We came to thy brother Esau, and moreover he cometh to meet thee, and four hundred men with him.” (Genesis 32:7) Why does the Torah take pains to tell us the exact number of men accompanying Esau? Servants of Esau are of no particular significance. It is apparent that, by specifying the number of men in Esau's entourage, the Torah is trying to tell us something about Esau. It seems to me that Jacob understood the significance of the number 400. This number is a sum of the powers of 7 from 0 to 3: 70+71+72+73=400. These four powers of 7 hint at the lunar month, which has approximately 28 days (4×7). The significance of this will become apparent later. 400 is a repdigit (a portmanteau [...]

The Meaning of Life as Taught by Bayesian Angels

November 19, 2018 And he [Jacob] dreamed, and behold! a ladder set up on the ground and its top reached to heaven; and behold, angels of G‑d were ascending and descending upon it. (Genesis 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 [...]

Jacob Teaches Wave-Particle Duality

…and he [Jacob] took some of the stones of the place and placed [them] at his head, and he lay down in that place (Gen. 28:11) And Jacob arose early in the morning, and he took the stone that he had placed at his head, and he set it up as a monument, and he poured oil on top of it. (Gen. 28:18) And Jacob said to his kinsmen, "Gather stones," and they took stones and made a pile, and they ate there by the pile. (Gen. 31:46) The debate about the nature of matter goes back to antiquity. According to atomist school of thought (Leucippus, Democritus, Epicurus, Lucretius), the matter is composed of particles or atoms. The light was also thought to be made of particles – the corpuscular theory of light (Alhazen, Newton). [...]

The Second Derivative — The Secrets of The Double Cave

And he [Avraham] spoke with them, saying, “…Listen to me and entreat for me to Ephron the son of Zohar. That he may give me the Machpelah (Double) Cave, which belongs to him, which is at the end of his field…" (Genesis 23:8-9) double: A house with an upper story over it. Another interpretation: because it was doubled with couples (Er. 53a) (Rashi on Genesis 23:9) In the Torah portion Chayei Sarah, Avraham purchases a Double Cave, Machpelah, as the ancestral burial plot. Almost all classical Biblical commentators interpret Machpelah (that is, "double") to mean a cave with two chambers. Rashi takes an entirely different approach and states that the cave was known for a two-story house built on top of it. So, the word Machpelah refers not to the cave itself, but to [...]

Biblical Relativity

And the life of Sarah was one hundred years and twenty years and seven years... (Gen. 23:1) Why did Esther merit to rule over 127 countries? Said G‑d: “Let Esther, the descendant of Sarah who lived 127 years, come and rule over 127 lands. (Esther Rabbah 1:8) The Midrash Ester Rabbah compares 127 years of Sarah’s life with 127 provinces that Esther ruled. How can one compare time with space? When the Midrash says that Adam gifted 70 years of his life to his descendant, King David, it’s understandable – a year for a year. But a year for a province? What’s the connection? Hermann Minkowski When, in 1905, Albert Einstein published his Special Theory of Relativity, it was nothing short of a scientific revolution. For the first time, Einstein showed [...]

Wellsprings from Above and Wellsprings from Below

In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month… all the fountains of the great deep were broken up, and the windows of heaven were opened. (Gen. 7:11) In calculating the time of the dawn of Messianic revelation, the Zohar writes, And after six hundred years of the sixth thousand there will be opened the gates of wisdom above and the fountains of wisdom below, and the world will make preparations to enter on the seventh thousand as man makes preparation on the sixth day of the week, when the sun is about to set. (Zohar I, 117a) The Zohar calculates this based on the letters of the Tetragrammaton, but brings the verse from this parashah as the mnemonic: “In the six hundredth [...]

Day Six – the State of Superposition

And G‑d saw all that He had made, and behold it was very good, and it was evening and it was morning, the sixth day. (Gen. 1:31)   The Biblical narrative of creation concludes with the above verse. Rabbi Shlomo Yitzchaki (a.k.a. Rashi) comments on this verse: the sixth day: Scripture added a “hey” on the sixth [day], at the completion of the Creation, to tell us that He stipulated with them, [“you were created] on the condition that Israel accept the Five Books of the Torah.” [The numerical value of the “hey” is five.] (Tanchuma Bereishith 1). Another explanation for “the sixth day”: They [the works of creation] were all suspended until the “sixth day,” referring to the sixth day of Sivan, which was prepared for the giving of the Torah (Shab. 88a). [...]

Shabbat Bereshit – Past, Present, and Future

In the last post, Tishrei—Past, Present, and Future, we discussed how all Tishrei holidays – Rosh HaShanah, Yom Kippur, Sukkot, and Simchat Torah – are connected by the same thread of time and, more specifically, the unification of past, present, and future. This cluster of Tishrei holidays is culminated and concluded with Shabbat Bereshit, when we start the new annual cycle of reading the Torah. Not surprisingly, Shabbat Bereshit follows the same pattern of unification of past, present, and future. The Torah starts with the creation of the world. The story of Creation, obviously, relates to the past. The word “bereshit,” means, in the beginning. The root of “bereshit" is “reshit” – beginning. Beginning, however, points into the future – to something that will follow the beginning in the future. The Lubavitcher [...]

Tishrei — Past, Present, and Future

The months of Tishrei is full of holidays, and they all share a common theme—the unification of time—past, present, and future. Picart, Blowing of the Shofars on Rosh Hashanah It all starts with Rosh HaShanah. Traditionally translated as the New Year, it literally means the Head of the Year. The word shanah has the same letters as the word shinui — “change.” As Aristotle famously wrote, time is change. The sages of Kabbalah agree—time, in its essence, is change. Thus, Rosh HaShanah can be translated as the Head of Time, or the Beginning of Time (since a related Hebrew word, reshit means the “beginning”). Indeed, it is all about time. Rosh HaShanah has three main themes—Ziḥronot (remembrances), Shofrot (Sounds of the Shofar), and Malkhiot or  Kabalat Ol Malkhut Shamayim (acceptance of [...]
