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 video, taken by Patrick G in France and copied here with his permission shows his Strike 20 trimaran on its fourth sail. I quote from his email " we achieved 9 / 10 kt to windward, 16 kt broad reaching under gennaker ( 14.8knots over 500 m and 14.3 over a nautical mile) The Strike 20 has a simple dory shape plywood main hull and uses beach cat outriggers and rig. so it is an easy cheap way to build your own performance trimaran.
