COUPLED QUARK SYSTEM. “At large energy and momentum scales, the interaction is relatively weak, whereas at lower energy scales the picture is clouded by the increasingly strong interaction.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

PROTON INNARDS. “The structure of the proton is a prototypical example of a strongly coupled and correlated system with quarks and gluons interacting according to quantum chromodynamics (QCD).” View in LinkedIn

I must have taken this shot fifty times but simply cannot resist it when I see it. Girona cathedral at its best. View in LinkedIn

POWERFUL IMAGES. “It has long been claimed that imagery can have unique, if not profound, effects in physiological activity and health. With few exceptions, most of these observations have been ignored by mainstream medicine and psychology.” (Chapter 2). https://lnkd.in/dfMNaXbV View in LinkedIn

THE IMAGINATION. “The neurobiological substrate of the tinkering process could be found in a hierarchical model of the brain characterized by a multiplicity of functional modules (FMs) that can be assembled according to different spatial and temporal scales.” (Fascinating article). https://lnkd.in/dJ8dUGRd View in LinkedIn

ONE EXPLANATION. “Pauli blocking may lead to a flavour asymmetry as the extra u valence quark Pauli blocks some matter-antimatter pairs from forming.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

A DOOR OPENS. “These results are expected to revive interest in several proposed mechanisms for the origin of this antimatter asymmetry in the proton that had been disfavoured by previous results, and point to future measurements that can distinguish between these mechanisms.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

THE ETHER. “What is space made of? This is a question that has puzzled mankind for thousands of years. Before Einstein put forward special relativity, it was generally believed that space is filled with aether.” https://lnkd.in/dATr5iE7 View in LinkedIn

UNRESOLVED. “The theory of relativity eliminated the need for a light-transmitting medium, so that today the term ether is used only in a historical context.” https://lnkd.in/dfqNVnY7 View in LinkedIn

HISTORICAL FOOTNOTE. “Ether was held to be invisible, without odor, and of such a nature that it did not interfere with the motions of bodies through space. The concept was intended to connect the Newtonian mechanistic wave theory with Maxwell's field theory. However, all attempts to demonstrate its existence, most notably the Michelson-Morley experiment of 1887, produced negative results and stimulated a vigorous debate among physicists that was not ended until the special theory of relativity, proposed by Albert Einstein in 1905, became accepted.” https://lnkd.in/dfqNVnY7 View in LinkedIn
