Rebuilding Communication from the Heart Outward

medium.com — There are different opinions about the starting point of language. It either occurred almost suddenly about 50–100k years ago (Chomsky) or slowly evolved from 2M years ago along Homo Erectus (Daniel Everett). In both cases we observe an evolution from simple structures to more complex ones. And now back to simple ones: the Emojis 😅. REBUILDING, 16

In-Depth Guide to the Best Free Fonts

beautifulwebtype.com — “Before he died in 2013, the great sociologist Robert Bellah said that his view of everything he’d studied across his life was tilted on its axis by this late recognition: when mammals began to bring forth offspring from the center of their bodies, spiritual life became possible. With apes and far more with humans, the period of necessary parental care—care in order for the offspring to survive—became longer and longer. The long helplessness of the child generated a sphere of softening, experimentation, and creativity in self-understanding and shared life.” IN-DEPTH, 18

Statistical rethinking with brms, ggplot2, and the tidyverse (2023)

bookdown.org — This ebook is based on the second edition of Richard McElreath’s (2020a) text, Statistical rethinking: A Bayesian course with examples in R and Stan. My contributions show how to fit the models he covered with Paul Bürkner’s brms package (Bürkner, 2017, 2018, 2022j), which makes it easy to fit Bayesian regression models in R (R Core Team, 2022) using Hamiltonian Monte Carlo. I also prefer plotting and data wrangling with the packages from the tidyverse (Wickham et al., 2019; Wickham, 2022). So we’ll be using those methods, too. STATISTICAL, 19
