   Why is Kahan so successful?

   • Kahan’s success shows that commitment to uncompromising technical rigor and academic excellence, coupled with more than a little luck, can transform real world computer hardware and software. Sometimes an idealistic refusal to accept the deficiencies of established ways of doing things really does pay off.

   How did Kahan develop a floating point algorithm?

   • He developed a program called "paranoia' in the 1980s to test for potential floating point bugs and developed the Kaham summation algorithm which helps minimize errors introduced when adding a sequences of finite precision floating point numbers. Kahan won the ACM A.M. Turing Award in 1989.

    Feb 20, 1998 · At Stanford ten years earlier, Palmer had heard a visiting professor, William Kahan, analyze commercially significant arithmetics and assess how much their anomalies inflated the costs of reliable and portable numerical software. Kahan had also enhanced the numerical prowess of a successful line of Hewlett-Packard calculators.
