Weekly Photo Challenge: Delta

The first thing came to mind on the word “delta” is the airline, but the photo challenge for this week is to depict something in transition or change, not sure how is that relate to delta. I was walking around downtown Chicago yesterday and snapped this photo; I am not trying to be political but it fits this challenge. Don’t you think so?

  1. Delta is a mathematical symbol for change or the amount of change, almost always written as a triangle/the Greek letter Delta for “D”. Sometimes it is pronounced “d” as in d-theta, change in theta. This is mainly used in calculus related problems. 🙂
