The Paradox of Steven Weinberg

The world has lost one of the greatest theoretical physicists of our time—Steven Weinberg (1933–2021). I never met him in person. But I studied his textbooks at university. His Gravitation and Cosmology, translated into Russian, was one of the few books I brought with me when we left the Soviet Union in 1982. This book is still on my shelf. Weinberg’s contribution to physics was enormous. His electroweak theory earned him a 1979 Nobel Prize in physics (which he shared with Abdus Salam and Sheldon Glashow). His work played an essential role in laying the foundation for the Standard Model of particle physics. He made significant contributions to the theory of strong nuclear forces, formulating the quark theory of strong interactions called “technicolor.” His idea of effective field theory changed our understanding of [...]

Unified Field Theory and the Dew of Resurrection

And ye shall take you on the first day the fruit of goodly trees, branches of palm-trees, and boughs of thick trees, and willows of the brook (Levit. 23:40) After completing his masterpiece, the General Theory of Relativity in 1916, Albert Einstein spent the rest of his life working fruitlessly on unifying gravity with electromagnetism. His quest was to develop a unified field theory that would unify his General Relativity, a theory of gravitational, with Maxwell electrodynamics. To his great dismay, Einstein never succeeded in developing a unified field theory. It was actually even worse. While working tirelessly on unifying two known classical fields – gravitational field and electromagnetic field – Einstein missed the incredible progress in quantum physics, of which he was one of the founders and for which he received his [...]

Abraham Meets Abraham From a Parallel Universe

And he [Abraham] lifted up his eyes and looked, and, lo, three men stood over against him…  (Genesis 18:2) On this blog, we often discuss the collapse of the wavefunction as the result of a measurement. This phenomenon is called the “measurement problem.” There are several reasons, for which the collapse of the wavefunction—part and parcel of the Copenhagen interpretation of quantum mechanics—is considered a problem. Firstly, it does not follow from the Schrödinger equation, the main equation of quantum mechanics that describes the evolution of the wavefunction in time, and is added ad hoc. Second, nobody knows how the collapse happens or how long the wave function takes to collapse. This is not even to consider that any notion that the collapse of the wavefunction is caused by human consciousness, as proposed [...]

Symmetry and Love — Jewish Chromodynamics

Ye are standing this day all of you before the Lord your God: your heads, your tribes, your elders, and your officers, even all the men of Israel, your little ones, your wives, and thy stranger that is in the midst of thy camp, from the hewer of thy wood unto the drawer of thy water; that thou shouldest enter into the covenant of the Lord thy God—and into His oath—which the Lord thy God maketh with thee this day. (Deut. 29:9-11) The above verses at the beginning of the Torah portion Nitzavim that is always read in the week preceding the Jewish New Year, Rosh HaShanah, are usually interpreted in terms of the unity of Jewish people: You are standing this day all of you [read: standing together in perfect unity]. This is not [...]
