Orthogonal, towards MIT

Walking along the Charles River on the Cambridge side late this afternoon, I glanced southeast towards Boston across the river and was blinded by the glare of sunlight reflecting off the ice. How can the setting sun attack from the southeast?!

The riddle is solved when you see that the stainless steel roof structure and/or windows at 111 Huntington Avenue had caught the rays of the setting sun from the southwest (see shadow on the buoy in the river) and reflected them at a right angle towards MIT.

Is there a "pi" in this somewhere?

I think it's an interesting observation, well worth a minute of time or skipping past if you prefer. Of course, ice plays a much bigger part in our lives here.
