Fermi Problems-Enrico Fermi studied physics and Maths. He liked to pose seemingly impossible questions. “Fermi Problems” celebrate his ability to estimate and play around with problem-solving! NOW...see if you can think like Fermi...help us learn like Fermi by posing a Fermi Problem for our Mathematically crazy class!!! An example we used today was, "How many cans of dog-food do our neighbourhood dogs consume in one night?" Another Fermi Problem I remember is my uncle asking my dairy farmer Dad how many milk shakes his cows could provide in one year!
