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 Yacht club boat just had about $9,000 spent on it after an August 2021 survey. Don’t be fooled by the hours on the main engine, she runs great. The owner loves this boat but sadly is aging out of ownership. The custom hardtop , stainless arch and stainless bow rail accent the classic fine lines of this semi displacement Shamrock. The keel also enhances the boat’s overall stability and tracking, and makes it predictable and seaworthy in heavy seas. Also the patented Shamrock keel drive system protects the hull, prop and rudder. Some other features include: Bruce anchor and windlass, Uniden VHF, trim tabs, Furuno GPS, sounder, spacious Vberth, enclosed head, 351 ford motor with closed cooling, 2 marine batteries and isolator switch, below deck storage, new raw water pump.
