72. Heaviside-Lorentz Units Rationalization was encouraged by oliver heaviside and HA Lorentz,after which the resulting system of units is named. heaviside http://www.du.edu/~jcalvert/phys/hlu.htm

Heaviside-Lorentz Units Rationalizing Maxwell's Equations Maxwell's equations in Gaussian units are shown at the right. Gaussian units are based on the cgs system of mechanical units, and were long dominant for theoretical investigations. Absolute electrostatic units (esu) are used for electrical quantities, absolute electromagnetic units (emu) for magnetic quantities. The electric field E and the magnetic flux density B are the basic vectors; D and H are obtained from them by adding the polarization P or subtracting the magnetization M , respectively. If P and M are proportional to the applied field, then D and B are related to E and H b and J b , where the "b" stands for "bound." The divergence of D and the curl of H give the "free" charge and current densities, respectively, while the divergence of E and the curl of B give the total charge and current densities. The Lorentz force on a point charge q is also given, where E and B are the effective fields on the charge q, where polarization and magnetization are zero. The energy definitions of resistance R, capacitance C and inductance L are shown. Charges are in esu, currents in esu/s in these equations. The universal constant c = 2.9979 x 10 cm/s, the speed of light.

Nahin; IEEE Press; New York 320 pages; $57.95 ($43.45 for IEEE members) Victorian engineer and scientist Oliver Heaviside “with no formal education after the age of sixteen, eventually came to be accepted as the intellectual equal of the finest scientific minds of the day,” writes engineering professor Paul Nahin in Betting the parameters for this biography. Heaviside resigned from his one and only job at age twenty-four. ... [He] knew the power of money and desired it, but refused to work for it, preferring to live off the sweat of his family and long-suffering friends whom he often insulted even as they paid his bills.” THE REALITIES OF NUCLEAR POWER: International Economic And Regulatory Experience Steve D. Thomas; Cambridge University Press; Cambridge; 289 pages; $59.50 New orders for nuclear plants have dwindled to almost nothing, providing a logical moment to re-evaluate the promise of nuclear power, says Thomas, from the Science Policy Research Unit at the University of Sussex. He notes that some countries have been able to build nuclear power plants quickly and cheaply and operate them effectively, while other countries have not.

77. Transverse Electromagnetic Wave; Scandals In Electromagnetic Theory History of Maxwell’s Equations. Ido Yavetz, From Obscurity to Enigma. The Workof oliver heaviside, 18721889, pub. Birkhauser Verlag, Basel. P6, footnote 17. http://www.ivorcatt.com/2604.htm

The Heaviside Signal The Heaviside Signal An alternative view of the transverse electromagnetic wave. By Ivor Catt Wireless World, July 1979 Maxwell faced up to the paradox that whereas electric circuits, in order to function properly by allowing the passage of electric current, were thought to require a complete closed circuit of conductors, electric current still seemed to flow for a time when a capacitor (which of course is an open circuit) was placed in series with the closed loop of conductors. He “cut the Gordian knot” (according to Heaviside in his Electromagnetic Theory , 1893, London, p28 sect 30) by postulating that a new kind of current, which he called “displacement current”, leapt across the plates within the capacitor. This electric current, which was uniformly distributed in the space between the capacitor plates, could even flow through a vacuum. Maxwell followed up this daring idea by suggesting that electromagnetic waves might exist in space. Scepticism about his postulated “displacement current” was silenced in 1887 when Hertz discovered the predicted waves in space. The classic pre-Popperian requirement of a good scientific theory seemed to have been met – the prediction of further results which are later confirmed by experiment. There are two versions of the transverse electromagnetic wave, the “rolling wave”, and what we shall call here the “Heaviside signal.” We shall discuss only the wide variety of views among those who believe (with the relativists) that there is no instantaneous action at a distance.
