What is Relativity?
In physics, the basic definition of relativity is that physical phenomena are highly dependent upon the position (motion, etc) of the observer.
I was in Minneapolis recently for work. It was a super windy day with 40-50 mph gusts. It was the worst airplane landing I had ever experienced with the plane violently rocking back and forth and up and down right up until touchdown. The wind made the trunk lid slam into my head as I was putting my luggage in the trunk. I headed to Trader Joe’s to buy my imports. As I was checking out, the lady said: “Isn’t it a lovely day? Every day is a lovely day when you don’t live in Duluth!” Hilarious, right? Except I sort of didn’t get it because I’ve never been to Duluth. I’m assuming this is similar to us (in Anchorage) saying in the middle of winter: “At least it’s not Fairbanks!” (which is probably lost on YOU, dear reader!).
