While walking around the park taking bleak, wintry pictures, I happened upon a boy with a perfect-snowball-making device. I asked him if he would make one for me so I could photograph it. “I like taking pictures of math, ” I said. He produced the following sphere for me.
I then asked if he would hold the snowball in his hand so I could photograph that, too. He responded matter-of-factly, “Then I’ll throw it at you”. It seemed like a reasonable deal, so I agreed.
