In the twenty-first century, electronic agents will be our servants on the great web of knowledge. They will use the kind of feedback that won World War II. Feedback mathematics is invented to help guns hit their targets. The concept of feedback originated in the vineyards of France by a winemaker and physiologist named Claude Bernard. His ex-wife began the Humane Society, created to save people from drowning. Drownings increased due to an increase in shipping. All of this eventually leads to the hiring of a doctor at a sanitarium in Michigan. The doctor tries out new diets on the patients. The most successful product is named after him -- Kellogg's cornflakes.
