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/
Reefing lines are important on a sailboat because they enable us to reef down the main sail (reduce sail area) when in strong winds. We had accidentally crossed two of our reefing lines when we rerouted them to make place for our new staysail halyard. This faux pas meant Adam couldn't reef our main sail when he needed. Although conditions were fine at the time, we're lucky he caught this now and we avoided a serious situation that could have occurred because of this mistake.
