I took this image of Chicago after dusk on December 20th last year. What do you see?
Some may say they see a city alive, from the skyscrapers to lakefront to the bustling streets that run through Chicago’s commercial, industrial, and residential zones.
Personally, I see photons. Lots and lots of stray protons, all of them moving up. Beyond the few markers intended for aviation safety, the sources of these photons are illuminating spaces beyond their intended targets.
