Where Is Your Compass Pointing?
Have you ever really looked at a compass? I’ve never had a need for a compass before but I have one on my cell phone and thought it would be fun to play with it once. I opened the app, turned around until the compass pointed north and then watched as the dial slowly creeped from side to side. I was trying to sit very still, but just my shallow breathing was enough to move me and the compass needle a few degrees off north. So I thought if I put it down on a solid surface, I could move it around until it was at 0º and it would stay there, but I was wrong! Perhaps, no matter how still I try to be, my position in relation to north is always changing slightly as the earth orbits.
