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/

This was a scouting cruise on a catamaran through the southern Dalmatian islands, designed to explore and shape a new route for an upcoming regatta. A warm spring day, the promise of summer in the air, a near-complete calm on the water, and a crew in high spirits — the perfect setting for inspiration and discovery. Video by @NesterovMikhail
