EXPLAINING THE HEAVENS. “Our best-fitting model suggests a scenario in which disc instabilities are the main driver for moderately luminous Seyfert galaxies at low redshift, while major mergers are the main trigger for luminous AGN.” (AGN = active galactic nuclei). https://lnkd.in/d9JV8md View in LinkedIn

DOWNSIZING EXPLANATION. “With these three modifications, the models can explain the observed downsizing, successfully reproduce the bolometric AGN luminosity function and simultaneously reproduce galaxy and BH properties in the local Universe.” (BH = black hole; AGN = active galactic nuclei). https://lnkd.in/d9JV8md View in LinkedIn

WARP SPEED. “When the Chinese released the sequence of the SARS-CoV-2 virus, we started the process of making RNA the next day. A couple weeks later, we were injecting animals with the vaccine." A very long time to until the acceptance of mRNA vaccines, whose promises for the future are considerable. See my TEDx talk. https://lnkd.in/dc32WbP View in LinkedIn

HIERARCHICAL MODEL. “In this model, BHs evolve from light seeds (∼100 M⊙) and their growth is merger driven. The original Somerville et al. model (baseline model) reproduces the number density of AGN at intermediate redshifts and luminosities, but underproduces luminous AGN at very high redshift (z > 3) and overproduces them at low redshift (z < 1).” (BH = black hole; AGN = active galactic nuclei). https://lnkd.in/d9JV8md View in LinkedIn

COEVOLUTION OF LANGUAGE AND MATHS. “I will show in this essay that the origin of verbal language and mathematics depend on each other. We will explore the notion that mathematics is part of an evolutionary chain of six languages. One does not ordinarily think of computing and the Internet as languages but I will demonstrate that speech, writing, mathematics, science, computing and the Internet form an evolutionary chain of six languages.” https://lnkd.in/dq9dXxs View in LinkedIn

FRAGMENT FROM NATURE features for this and next weekend an excellent article by media ecologist and MIT-educated physicist Robert K. Logan, on the relationship between mathematics and language. His very original hypothesis runs counter to traditional thinking on the topic, and suggests that they are very intimately related in unexpected ways. https://lnkd.in/dKUCtJu View in LinkedIn

SETS AS A PRECONDITION. “We further suggest that verbal language emerged as a primitive form of set theory in that a set of percepts that are associated with each other or are similar are linked together with a word acting as a concept that unites all the members of that set. In a certain sense the primitive form of set theory we just described seems to be a pre-condition for the emergence of verbal language.” https://link.springer.com/chapter/10.1007/978-3-030-59177-9_13 View in LinkedIn
