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/

The Lagoon 570 is a large catamaran with plenty of space on board and can accommodate up to 10 guests in 5 double en-suite cabins with separate crew quarters for a Skipper or extra guests. This is one of the nicest presented Lagoon catamarans that we have had on our listings and is always kept in absolutely immaculate condition inside and out in fact I do not feel that you would find better without a long hard search, this catamaran is a real beauty! One of the older style Lagoons, which in many peoples opinion was a much better sailing yacht, better built with a generous degree of performance compared to the newer options..... This catamaran is based in Portugal and is ready to go now and expected to sell quickly, due to her lovely condition and current demand for the larger older style catamarans. With this catamarans spacious layout it would be an ideal crewed charter option or a superb private family world cruiser. Maintained to perfection by her carefully owners and fully loaded with options, the yacht is extremely well equipped. If your looking in the 60ft foot range for a catamaran you owe yourself a trip to see this one as it is rather special with huge cockpit and luxurious saloon there is plenty of space on board for family friends or charter guests and rarely available this side of the pond.
