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/

Today we found a spare part for our watermaker that has historically been difficult for us to find- no problem here in St. Maarten! This place is ideal for boat supplies.

Après le passage du cap Horn il y a quelques jours, François Gabart a connu une zone de pétole avec grand soleil. Désormais, MACIF navigue dans des conditions tout à fait différentes avec du gros temps et une belle tempête.
