Numerical analyst who decoded computing's hidden errors
"The modern computer is a most extraordinary and wonderful device; but if a man wants to use it intelligently he must understand its limitations."
Biography
James Wilkinson revolutionized numerical analysis and error theory in computing, establishing foundational principles for understanding how rounding errors propagate through algorithms. His work at the National Physical Laboratory made him a pioneer in computational mathematics, influencing generations of computer scientists and mathematicians. He demonstrated that seemingly small computational errors could have catastrophic consequences, reshaping how algorithms are designed and analyzed.
Key Facts
- Developed Wilkinson's backward error analysis, proving that computed solutions are exact for slightly perturbed input problems
- Created the famous Wilkinson polynomial W(x), which demonstrates extreme sensitivity to small perturbations in coefficients
- Spent his entire career at the National Physical Laboratory in Teddington, England
- Published 'The Algebraic Eigenvalue Problem' (1965), considered the definitive text on computational linear algebra
- Won the Turing Award in 1970 for his contributions to numerical analysis and computing
A rounding error changed everything we know about computing.
