- When I moved to Minneapolis from upstate New York last year, I found myself puzzled by the layout of the streets and avenues across the city. Why, for example, did every street and avenue in my neighborhood have Southeast (SE) as a suffix? And why did that change to South (S) when I went to neighborhoods like Seward and Whittier? These questions lingered in my mind while wandering the city by bike, bus and light rail. I tried to find the origin of the north–south divide and the east/not-east divide, as well as the underlying structure of the streets and avenues.

We’re attempting to get a collection of humans to say every digit of the newly-discovered (and currently largest-known prime number) Mersenne prime M136279841, and hope to achieve this before another larger prime is discovered.
