“WORDS glisten. Words irradiate exquisite splendor. Words carry magic and keep us spell-bound...Words are like glamorous bricks that constitute the fabric of any language... Words are like roses that keep the environment fragrant.” https://lnkd.in/gFvYmUMn View in LinkedIn

CUBISM AND RELATIVITY. “There has been much controversy on the more specific issue of the possible relationship between Cubism and Einstein’s concept of space-time.”" " " " https://lnkd.in/gh462Xjw View in LinkedIn

QUANTUM + RELATIVITY. “Indeed, the phenomenal accuracy of quantum electrodynamics is, according to Feynman, the result of painstaking calculation of more and more complex and unlikely paths, and adding their contribution to the result. He saw his theory as a marriage of quantum mechanics and relativity.” https://lnkd.in/gDaxUYAS View in LinkedIn

POOR RECEPTION. “From our viewpoint of events proceeding from the past to the future, the general distaste for the Feynman-Stueckelberg interpretation is understandable, but is it justified?” https://lnkd.in/gDaxUYAS View in LinkedIn

EXAMPLE. “Imagine a physicist at time T1 creating an electron and a positron from a photon, storing them until time Tn when the antiparticle is annihilated by another electron. He describes the situation as negatively charged, positive energy electrons and a positively charged, negative energy positron, all moving forward in time.” https://lnkd.in/gDaxUYAS View in LinkedIn

BACKWARDS IN TIME. “Feynman describes three otherwise identical electrons, one moving backwards in time. R. Penrose has popularized the concepts of unitary, deterministic evolution in time according to the Schrodinger equation, the "U-process", versus quantum state vector reduction, the "R-process", or collapse of the wave function.” https://lnkd.in/gDaxUYAS View in LinkedIn

PENROSE’S CONSEQUENCES. “During the U-process, symmetric in time, a superposition of states exists in which all the possible fates of the two particles exist.” https://lnkd.in/gDaxUYAS View in LinkedIn

CONSENSUS. “Physicists insist that the Schrodinger equation is symmetric in time and has no preference for a particular now. Let us take this completely seriously.” https://lnkd.in/gDaxUYAS View in LinkedIn

THE CAMBRIDGE PHILOSOPHICAL SOCIETY. “Adam Sedgwick (1785–1873) and John Stevens Henslow (1796–1861). Both men were aware that the study of the sciences in their University was largely moribund. Although there were professors of both botany and geology at Cambridge, and post-Newtonian mathematics was flourishing, the sciences...were a “peripheral activity”. The purpose of the University was primarily as a training ground for clerics.” https://lnkd.in/gkn3BKFd View in LinkedIn
