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/

Making its first appearance back in 1999, the Oxygen continues the legacy of being a proven and reliable freeride design. Sporting fresh new colours for the coming season, the updated Oxygen has a higher aspect ratio that allows for the use of a shorter boom. The mast length increase is balanced by the introduction of a closed sleeve head, replacing the previous plug fitting. Luff curves and leech configuration had been redesigned to offer more solid bottom end power and a higher range of trim possibilities. Learn more: https://www.loftsails.com/windsurf-gear/sails/oxygen
