Bivector

Around this time Josiah Willard Gibbs and Oliver Heaviside developed vector calculus, which included separate cross product and dot products that were derived from quaternion multiplication.

Cross product

Oliver Heaviside in England and Josiah Willard Gibbs, a professor at Yale University in Connecticut, also felt that quaternion methods were too cumbersome, often requiring the scalar or vector part of a result to be extracted.

Ernst Julius Berg

In the field of theoretical analysis of electrical circuits, he popularized Oliver Heaviside's technique of operational calculus.

George Ashley Campbell

In fact, neither man was the first to suggest the idea of loading coils, that credit goes to Oliver Heaviside in an 1887 article.

George FitzGerald

In particular, FitzGerald used some equations that had been derived a short time before by his friend the electrical engineer Oliver Heaviside.

Along with Oliver Lodge, Oliver Heaviside and Heinrich Hertz, FitzGerald was a leading figure among the group of "Maxwellians" who revised, extended, clarified, and confirmed James Clerk Maxwell's mathematical theories of the electromagnetic field during the late 1870s and the 1880s.

Length contraction

Although both FitzGerald and Lorentz alluded to the fact that electrostatic fields in motion were deformed ("Heaviside-Ellipsoid" after Oliver Heaviside, who derived this deformation from electromagnetic theory in 1888), it was considered an ad hoc hypothesis, because at this time there was no sufficient reason to assume that intermolecular forces behave the same way as electromagnetic ones.

Operational calculus

This technique was fully developed by the physicist Oliver Heaviside in 1893, in connection with his work on electromagnetism.

Otto Julius Zobel

Campbell had previously utilised the condition discovered in the work of Oliver Heaviside for lossless transmission to improve the frequency response of transmission lines using lumped component inductors (loading coils).

The Partland Brothers

They played in many area bands before moving their act to Toronto in 1979 and forming Oliver Heavyside (ostensibly named after the British engineer, “Oliver Heaviside”), a Toronto bar staple for years.

Vector calculus

Vector calculus was developed from quaternion analysis by J. Willard Gibbs and Oliver Heaviside near the end of the 19th century, and most of the notation and terminology was established by Gibbs and Edwin Bidwell Wilson in their 1901 book, Vector Analysis.
