So how many piano tuners could NYC support?- 160,000/800 = 200 piano tuners.How many piano tunings can one piano tuner do? - Let’s say four per-day, so if there’s 200 working days in a year, that’s 800 per year.How often per year do pianos need to be tuned? - Once per-year.So how many pianos are there in NYC? - 160,000 Zinovy Pritsker Piano Tuner Write a review Add photo Location & Hours 1510 York Ave New York, NY 10021 79th St & 80th St Yorkville, Upper East Side Get directions Edit business info Other Musical Instruments & Teachers Nearby Sponsored Orpheus Academy Learn to play music from the comfort of your home with Online Music Lessons.Does every family own a piano? - No… Perhaps one in ten does.So how many families are there in NYC? - 1,600,000.How large is the average family? - 5 People.Can we assume that families own pianos, not individuals? - Yes.Roughly how many people live in New York City? - 8,000,000.A way that he explained his method for estimation was what sparked the title of this post: “How Many Piano Tuners are there in New York City?” Below is an example breakdown of how he’d go about estimating the problem from the excellent article referenced above: Fermi made the closest estimate of the strength of the atomic bomb test, based on pieces of paper he dropped from his hand during the blast. The premise is simple when trying to estimate something so large that it would either be wildly inaccurate at best or utterly impossible at worst, to break it down into smaller, more easily understandable parts.Įnrico Fermi was an Italian-American physicist and inventor of the world’s first nuclear reactor, among other things. A few years later though, I came across a article that all of a sudden made what the data scientist was saying not only make sense, but also very relevant. When I first heard about the Fermi Problem, it was by a data scientist “nerding out” about things so far over my head. ![]()
