"I argue that inclusion of Occam's razor is an essential factor that distinguishes science from superstition and pseudoscience. I also describe how the razor is embedded in Bayesian inference and argue that science is primarily the means to discover the simplest descriptions of our world."

"The study has revealed that the Balkans was a frontier region of ancient Rome as cosmopolitan as the imperial centre, and that Slavic migration arriving in the Balkans from the 6th century onwards represents between 30% and 60% of the ancestry of the Balkan peoples today." https://www.ehu.eus/en/web/campusa-magazine/-/ancient-balkan-genomes-reveal-how-slavic-europe-was-formed #Science #STEM #Ancient #DNA #Human #Population #Europe #Genetics #Biology @biology @science
"The authors introduce the two main theoretical approaches in SM, Boltzmannian SM and Gibbsian SM, and discuss how they conceptualise equilibrium and explain the approach to it. In doing so, the authors examine how probabilities are introduced into the theories, how they deal with irreversibility, how they understand the relation between the micro and the macro level, and how the two approaches relate to each other."

"The findings gave a unique understanding of life and death in this early Christian Viking community and indicated that it was common to suffer from dental caries, tooth loss, infections of dental origin and tooth pain. These Vikings also manipulated their teeth through filing, tooth picking and other occupational behaviors."

"To address questions about the real appearance of St Anthony, we applied body mass estimation equations to the osteometric measurements taken in 1981, during the public recognition of the Saint’s skeletal remains. Both the biomechanical and the morphometric approach were employed to solve some intrinsic limitations in the equations for body mass estimation from skeletal remains. The estimated body mass was used to assess the physique of the Saint with the body mass index."

"Medieval hospitals were founded to provide charity, but poverty and infirmity were broad and socially determined categories and little is known about the residents of these institutions and the pathways that led them there. Combining skeletal, isotopic and genetic data, the authors weave a collective biography of individuals buried at the Hospital of St John the Evangelist, Cambridge."

The secrets of Einstein's unknown equation – with Sean Carroll.
"The real Einstein's Equation is part of general relativity, which relates the curvature of spacetime to the mass and energy distributed within it.
Sean explains why the geometry of spacetime has anything to do with gravity, and how this famous equation expresses the way that spacetime curves." https://youtu.be/BRudidBcfXk #Youtube #Video #Science #Einstein #Space #Universe #Equation #Physics #Lecture @science @physics

"We consider two interacting systems when one is treated classically while the other system remains quantum. Consistent dynamics of this coupling has been shown to exist, and explored in the context of treating space-time classically. Here, we prove that any such hybrid dynamics necessarily results in decoherence of the quantum system, and a breakdown in predictability in the classical phase space."
