Mathematician:Oliver Heaviside

Mathematician
Largely self-taught English mathematician and physicist who was one of the pioneers in the field of electrical engineering.

Invented a considerable amount of the mathematics and terminology used in electromagnetism.

Significantly developed the theory of operational calculus, which are still used in modern-day mathematics in the context of Laplace transforms.

Developed a vector calculus independently of that of, completely independent of him.

Notable Quotes

 *  'Quaternion' was, I think, defined by an American schoolgirl to be 'an ancient religious ceremony'. This was, however, a complete mistake. The ancients -- unlike -- knew not and did not worship Quaternions.
