March 14th...giornata della matematica, Pi Greco day. Perchè non utilizzare le cifre di π per costruire una spirale, la spirale di Archimede, da appendere in classe o nel corridoio? Se appesa sopra un termosifone o un'altra fonte di calore, diventa una divertente attività ed esperimento con cui scoprire alcune caratteristiche dell'aria: la spirale ruota e si muove perchè spostata dall'aria calda. L’aria calda è più leggera dell’aria fredda perché meno densa e sale verso l’alto. https://maestramonica.it/pi-greco-day-la-spirale-di-archimede-matematica/

A quick intro to a relatively new feature, the carbon fiber steering wheel! We got a chance to see ours being built. Picking it up makes it feel like it is made from balsa wood. The weight of the assembly just about doubles when the stainless steel hub is added.
