“But that would mean it was originally a sideways number eight. That makes no sense at all. Unless..." She paused as understanding dawned. "You think it was the symbol for infinity?"
"Yes, but not the usual one. A special variant. Do you see how one line doesn't fully connect in the middle? That's Euler's infinity symbol. Absolutus infinitus."
"How is it different from the usual one?"
"Back in the eighteenth century, there were certain mathematical calculations no one could perform because they involved series of infinite numbers. The problem with infinity, of course, is that you can't come up with a final answer when the numbers keep increasing forever. But a mathematician named Leonhard Euler found a way to treat infinity as if it were a finite number- and that allowed him to do things in mathematical analysis that had never been done before." Tom inclined his head toward the date stone. "My guess is whoever chiseled that symbol was a mathematician or scientist."
"If it were my date stone," Cassandra said dryly, "I'd prefer the entwined hearts. At least I would understand what it means."
"No, this is much better than hearts," Tom exclaimed, his expression more earnest than any she'd seen from him before. "Linking their names with Euler's infinity symbol means..." He paused, considering how best to explain it. "The two of them formed a complete unit... a togetherness... that contained infinity. Their marriage had a beginning and end, but every day of it was filled with forever. It's a beautiful concept." He paused before adding awkwardly, "Mathematically speaking.”

“Are you grumpy in the morning?"
"No, but I wake up on the go. I don't like to linger over breakfast."
"You must not be doing it right. Lingering is lovely. I do it all the time." She stretched her arms and shoulders, and arched her sore upper back, her breast lifting with the motion.
Tom stared at her, mesmerized. "I might stay just to watch you linger.”

“Seven is my favorite number," he said.
"Why?"
He nuzzled gently at her stomach. "There are seven colors in a rainbow, seven days of the week, and..." His voice lowered seductively, "...seven is the lowest natural number that can't be represented as the sum of the squares of three integers."
"Mathematics," she exclaimed, laughing breathlessly. "How stirring.”

“She wore a dress of white satin, elegant and unusual in its simplicity, with no fussy ruffles and frills to distract from the lovely shape of her figure. Instead of wearing the traditional veil, she had drawn the sides of her hair up to the crown of her head and let the rest cascade down her back in long golden coils. Her only ornamentation was a tiara of graduated diamond stars, which Tom had sent upstairs that morning as a Christmas gift. The wealth of rose-cut gems glittered madly in the candlelight, but they couldn't eclipse her sparkling eyes and radiant face. She looked like a snow queen walking through a winter forest, too beautiful to be entirely human.
And there he stood, with his heart in his fist.”
