For some light summer amusement, I thought I would share a map I made a while back to satisfy my curiosity. I’ve had the plot in my office for several years and occasionally think to pull it out for visitors I suspect will enjoy it. I usually just hand it to them and let them puzzle over its meaning before I explain anything. It’s not meant to be an IQ test—although doubtless some feel that way—but rather a chance to delight in self discovery. I “discovered” the 7-24-25 Pythagorean triangle the other day quite by accident while constructing a relativity problem and was delighted by the find—even though Wikipedia has an exhaustive list of other sets wholly unknown to me. Likewise, I “discovered” Saturn as a 15-year-old on a summer night with a small telescope just poking around an unfamiliar sky. I danced around the yard in delight. My point is that discovery is personal, even if not original.
So here’s a chance to discover what the map is meant to convey. I’ll naturally explain later.
