We dive into how limbless movers—snakes, slugs, and more—convert wiggling waves into straight-line propulsion through directional friction. Learn about frictional anisotropy, the isotropic-sleeve experiment that stops forward motion, and the idea of a mechanical rectifier that turns oscillation into sustained thrust. From tribology and deterministic surface textures to biomimetic designs inspired by reptile skin, we explore how nature’s friction tricks could inform more efficient engines and ...

We start with Steno’s law and the idea that older stuff lies deeper, then ride into the archaeologist’s toolkit for turning messy ground into a timeline: the Harris Matrix, context by context. You’ll learn why physical height isn’t a guaranteed guide to age, what reverse or inverted stratigraphy looks like in the real world, and how deposits can be disturbed by people and nature to flip the apparent order. We’ll unpack common pitfalls—palimpsests, bioturbation, and redeposited fills—and show ...

Ecco che si torna a parlare del ritardo che il mondo manifatturiero, soprattutto le aziende medio-piccole italiane, hanno accumulato relativamente ai sistemi informativi ed alla cosiddetta “transizione digitale”, che comunque considero un’espressione fuorviante, perché dà l’idea che sia una cosa che una volta fatta … è fatta, e si può pensare ad altro.Non mi stancherò mai di dire che il mondo manifatturiero mi affascina tantissimo e che, se è vero che accusa un certo ritardo, non è per l’insipienza
