Por que o SÍMBOLO do DINHEIRO é um "S" CORTADO? #IberêResponde

Why is the symbol for money a crossed-out "S"? 💸 In today's Iberê Responds, we get straight to the point with a bunch of incredible questions: blackheads under the microscope (and that Demodex), a perfect Sun-Moon eclipse, why dividing by 0.5 increases a number, how ABS brakes work, why smoke rises (and when it falls!), vacuum that "swells" things, nearsightedness before glasses, seawater desalination, the smoothest material in the world, and much more. Check out Petrobras' Nossa Energia podcast: https://nossaenergia.petrobras.com.br/ There's also news: we'll be launching the Manual Maker — a website for downloading and sharing projects (3D printing, laser cutting, electronics, etc.) for free. Let's learn, build, and exchange knowledge with the community! www.manualmaker.com And, of course, check out all the Manual do Mundo books: https://www.amazon.com.br/shop/manual... #Petrobras #FederalGovernment #sponsorship #IberêResponde #Curiosities REFERENCES: Dollar Sign: https://es.wikipedia.org/wiki/Real_de... https://www.britannica.com/money/doll... https://en.wikipedia.org/wiki/Currenc...
