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/

While much of the team at Pioneer Sailing Trust has been busy preparing for the upcoming Ofsted inspection, it was very much business as usual on the water this morning. Work continued on Pioneer CK18, as Simon, Mick, and Teymour got stuck into the important job of transferring her spars back on board after their winter maintenance. Over the colder months, these components are often removed, inspected, and repaired to ensure everything is in top condition for the sailing season ahead. For those wondering, a spar is a general term used in boating to describe the poles that support and control the sails — such as masts, booms, and gaffs. They are essential parts of a sailing vessel, giving the sails their shape and allowing the boat to harness the wind effectively. It’s great to see the team’s dedication in action — balancing preparation onshore with hands-on work afloat, all helping to get CK18 ready for the months ahead. #pioneersailingtrust #historicvessel #pioneerck18 #boatlife #boats

It was a welcome return after a few days in the shed for Luna Rossa Prada Pirelli who looked utterly sublime in their LEQ12 (as they always do), revelling in the 13-15 knots conditions and determined to put maximum pressure on their Wing 03 and new Wing 04 to extract the maximum data. This was a session of rapid pace, searing bear-aways and plenty of straight-lining to validate the computer simulations in a very real world environment. The on-water recon team noted the sailors pushing the foils through rapid JKs and several stints of acceleration and deceleration as they assessed the stall and detachment points on the foils. The recon also noted take-off speeds between 17-18 knots and top upwind speeds of 36-38 knots whilst downwind the best guess was speeds at up to 45 knots – the bear aways were what Jimmy Spithill called “high numbers” as they really pushed the LEQ12 hard. #AC37Recon #shorts SUBSCRIBE to the official America's Cup channel: https://www.youtube.com/c/americascup Like America’s Cup On Facebook: https://www.facebook.com/americascup Follow America’s Cup On Twitter: https://www.twitter.com/americascup Follow America’s Cup On Instagram: https://www.instagram.com/americascup Stay up to date with the America’s Cup newsletter: https://www.americascup.com/en/newsletter The 37th America's Cup will be Defended in Barcelona by four-time America's Cup winner, the Royal New Zealand Yacht Squadron represented by their team, Emirates Team New Zealand. #AmericasCup #AC37 #Barcelona2024
