Principle of Least Action III — History

The spectacle of the universe becomes so much the grander, so much more beautiful, the worthier of its Author, when one knows that a small number of laws, most wisely established, suffice for all movements. Pierre Louis Maupertuis (1744) Among the more or less general laws, the discovery of which characterize the development of physical science during the last century, the principle of Least Action is at present certainly one which, by its form and comprehensiveness, may be said to have approached most closely to the ideal aim of theoretical inquiry. Its significance, properly understood, extends, not only to mechanical processes, but also to thermal and electrodynamic problems. In all the branches of science to which it applies, it gives, not only an explanation of certain characteristics of phenomena at present encountered, but [...]

Metaphysics of Time in the Eyes of Philosophy and Kabbalah

A-Series and B-Series as Zman and Seder HaZmanim McTaggart’s series A and series B are two conceptual frameworks proposed by the philosopher J.M.E. McTaggart[1] to analyze the nature of time and its relationship to temporal properties such as past, present, and future. J. M. E. McTaggart, by Walter Stoneman, 1917 In McTaggart’s series A, also known as the “A-series” or the “temporal series,” time is understood in terms of the temporal properties of past, present, and future. The A-series categorizes events based on their temporal relations, such as past, present, and future, which are considered essential aspects of events. The A-series views time as a succession of moments where events move from the future, through the present, and into the past. It emphasizes the dynamic and changing nature of time, with events shifting their [...]

Abraham and Lot—A Story of Decoherence

So Abram went, as the Eternal had spoken unto him; and Lot went with him… And Abram took Sarai his wife, and Lot his brother’s son… (Genesis 12:4-5) And Abram went up out of Egypt, he, and his wife, and all that he had, and Lot with him, into the South. (Genesis 13:1) And Lot also, who went with Abram, had flocks, and herds, and tents. And the land was not able to bear them, that they might dwell together; for their substance was great, so that they could not dwell together. And there was a strife between the herdmen of Abram’s cattle and the herdmen of Lot’s cattle. And the Canaanite and the Perizzite dwelt then in the land. And Abram said unto Lot: ‘Let there be no strife, I pray thee, [...]

The Soul is in the Blood

For the life of the flesh is in the blood." (Leviticus 17:11) The word translated here as “life” in the Hebrew original is nefesh, i.e., “soul.” Torah appears to be telling us that soul of every live creature is in its blood. Indeed, Rabbi Schneur Zalman of Liadi says so explicitly in the Tanya: The abode of the animal soul derived from kelipat nogah in every Jew is in the heart; in the left ventricle, as it is filled with blood, and it is written, 'For the blood is the soul' (nefesh)…. just as the blood has its source in the heart, and from the heart it circulates into every organ…" (Likkutei Amarim, 9)[1] The animal soul is primarily vested in the blood (from where it spreads to the whole body and beyond). What does [...]

Salt: The Covenant of the Opposites

And every meal-offering of thine shalt thou season with salt; neither shalt thou suffer the salt of the covenant of thy G‑d to be lacking from thy meal-offering; with all thy offerings thou shalt offer salt." (Leviticus 2:13)   Torah dictates that all offerings to G‑d must be brought together with salt. Classical commentators ask: What is so special about salt that it is an indispensable ingredient of any sacrifice? Moreover, why is it called the covenant of salt? Nachmanides explains: The Torah also uses this covenant as a model for other covenants, as both the priestly covenant[1] and the Davidic covenant[2] are called “covenant of salt” because they are upheld just as the sacrificial covenant of salt…. I am of the opinion that the significance is that the salt is water, which [...]
