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/

Killyleagh Yacht Club turned on the weather for the second open event of the the Strangford Lough summer of sailing. With sixteen boats on the starting line for the YTC 1 races there was close racing throughout the whole of the fleet. Race 1 was a close shoot out between the Mat1010 Elixir, J109 GTR and the local A35 for Mike Spence Le Basceleur. With the lead swapping many times both on corrected time and over the water it was Le Basceleur that came out on top closely followed by the Redline Racing team on the J109 GTR. The team at bottom up boats hope that you enjoy this short clip from our 2024 season on the water. Song: Cartoon, Jéja - On & On (feat.
