Organic cotton heaven ► http://bit.ly/2iZl1xR We're obsessed with figuring out ways to reduce the environmental impact of clothing! It keeps us up at night and makes some dinner conversations awkward. Or maybe we're just awkward to begin with? Nah, let's blame it on the clothing! We're super stoked to introduce our new hoodies, made with 100% combed organic cotton and a 90% reduced carbon footprint! We trimmed the fat by eliminating chemical inputs in the cotton farming process, using rainwater for 95% of irrigation needs, powering the process with renewable energy, and heaps more of super boring stuff, yada yada yada, they're super soft.

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/
