"Wanda dear, what is it that has you so engrossed¹?" asked Hari Seldon as he entered his granddaughter's office at Streeling University. The room had been the office of the brilliant mathematician² Yugo Amaryl, whose death had impoverished³ the Psychohistory Project. Fortunately,
    Wanda had gradually taken over Yugo's role in recent years, further refining and adjusting the Prime Radiant.
    "Why, I'm working on an equation in Section 33A2D17. See, I've recalibrated this section"-she gestured to a glowing violet patch suspended in midair in front of her face- `taking into consideration the standard quotient and- There! Just what I thought-I think." She stepped back and rubbed her eyes.
    "What is it, Wanda?" Hari moved in closer to study the equation. "Why, this looks like the Terminus equation and yet .     Wanda, this is an inverse⁴ of the Terminus equation, isn't it?"
    "Yes, Grandpa. See, the numbers weren't working quite right in the Terminus equation-look." Wanda touched a contact in a recessed⁵ wallstrip and another patch sprang to life in vivid red on the other side of the room. Seldon and Wanda walked over to inspect it. "You see how it's all hanging together fine now, Grandpa? It's taken me weeks to get it this way."
    "How did you do it?" asked Hari, admiring the equation's lines, its logic⁶, its elegance⁷.
    "At first, I concentrated on it from over here only. I blocked out all else. In order to get Terminus to work, work on Terminus--stands to reason, doesn't it? But then I realized that I couldn't just introduce this equation into the Prime Radiant system and expect it to blend right in smoothly8
