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/

Coral groupers can be seen on most reefs in Raja Ampat. They are a very colourful addition to the underwater seascape. Photographers might notice that they are quite curious and will often keep circling around to check if the camera is still pointing in their direction! Fun to watch and wonderful to capture on film.
