Small changes in the initial condition can generate huge differences.
Tonight I was walking when I went into University Hall. I found a paper airplane lying on the ground. I took it to the 4th floor a few times and watched it float down. The number of different paths is amazing. It’s a miracle that it landed anywhere it did.
I also found two dimes today both from the year 1989. Those two coins are older than I am and have traveled to places I can’t know. Now they are back with we for a bit.
I left the plain for someone else to find.
