what a long strange trip it's been

I asked Ryan (the resident genius here in Chez Wheaton, where our motto is "Mathus is Hardus") what the formula was to find circumference of a circle if you know its diameter.

"It's C = π⋅D" he said.

"Thanks," I said, "I can't believe I forgot that."

I got my calculator and put in 186000000 * 3.14

"Why didn't you remember that formula?" He said.

"Because that part of my brain doesn't get used as frequently as it once did, and even when it did get used, I had a . . . difficult . . . relationship with it."

584,040,00 came up on my display.

"Why did you want to know what it was?" He said.

"I just had this idea, and I wanted to know something . . ."

I typed in 58404000 * 34 and got back 19,857,360,000.

I looked up at him, unable to contain the huge smile that spread across my face.

"I've been riding this planet for almost twenty billion miles." I said.

"Woah." He said. "That's cool."

"Yeah," I said. "It really is."
