Showing results for "A Reflection" in Physics

Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

What if reality is not a branching forest of infinite timelines, but a single, irreplaceable world whose value becomes clearer the moment we strip away seductive myths? This book confronts one of the most persistent modern fantasies—the idea of parallel universes—by examining it through science, philosophy, and the psychology of human perception. It exposes how easily speculative models slip into pseudoscience, how cultural repetition creates the illusion of credibility, and how misused scientific language blurs the boundary between rigorous inquiry and imaginative fiction.

This fourth work aims to underline the perpetuating millennial mistake which consists of considering the weight unalterable and unchanging compared to the shape of the body itself. Together with this mistake, it is underlined how two mistakes of the scientific community, made in the last 40 years, are added.

Partendo da fenomeni elementari viene studiata la teoria della relatività generale di Einstein, unitamente al principio di Galilei sulla caduta libera dei gravi che ne è il presupposto. Il principio di Galilei prevede che tutti i corpi, prescindendo dalla loro massa, cadano con la stessa accelerazione di gravità. Invece, si constata la non vigenza di tale principio di Galilei non essendo detratta la massa del corpo di prova da quella della terra (ritenuta erroneamente costante), inoltre per non essere valutata la mutua attrazione reciproca dei corpi (sovrapposizione degli effetti).
