Spirals Round and Round
I saw a glassbow in the wild! That is, on the corner of 17th and Kilbourne Streets in Washington, DC.
Unfortunately, my glassbow was largely obscured by a tree’s shadow, and my phone’s camera is not the greatest, so my photo is nowhere near the quality of the gold standard.
The very fact that I noticed this bow at all is due to Walter Lewin and his masterfully taught course 8.03 Vibrations and Waves, which I was lucky enough to take in the fall of 2005. I still carry my wallet-sized linear polarizer. What kind of physicist would I be if I didn’t?
