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/

http://features.boats.com/boat-content/2013/09/sonar-smack-down-traditional-fishfinder-vs-down-looking-scanner-imager-vs-chirp/ For more electronics tests, visit www.boats.com. To all fishermen in search of a new fishfinder: if your head is swimming with gigamajigs, LCD screams, and watt-evers, you're not alone. A frequency frenzy has struck the world of sonar, and while we used to be able to compare a few specs, functions, and prices before drawing a reasonable conclusion as to which unit to buy, today the process is enough to make your head really kilohertz. Now there are entirely different forms of fishfinder technologies on the market and even for the most educated buyer, choosing between them is no easy call. We decided to help ease the digital delirium by matching up comparable technologies including traditional, scanning/imaging, and CHIRP, head to head. To keep the playing field level we capped the price range of the units we included at $800. This represents a sweet-spot for fishfinder manufacturers since most boat owners can afford a unit at this price or below, regardless of whether they cast for largemouth from a bass boat, troll for stripers in the bay, or jig for cod off the coastline. Sure, there's a lot more—and more advanced—technology available at higher price-points, but some costs as much as a small car and the vast majority of us will be living with something a little more affordable. So we put our focus here, in this moderate price range. We also tried to spread the field among the major manufacturers, which wasn't difficult since different companies have taken different technological routes to help get you to the fish.
