Synopsis
Learn how early scientists connected electricity, magnetism, and light with a common velocity. This book reveals the ideas behind their measuring systems and what they imply for modern physics.
The text explains how electrostatic and electrodynamic units relate through a definite velocity, and how the same velocity appears in the dimensions of different unit systems. It shows how figures from Weber, Kohlrausch, Kelvin, Clerk Maxwell, Ayrton, and Perry all point to a velocity close to the speed of light, reinforcing the electromagnetic view of light. The material also discusses how changing unit definitions affects the ratios between static and dynamic quantities.
Practical measurement methods are covered, including how to determine condenser capacity and how time, resistance, and frequency come together in bridges and other instruments. The appendix surveys experiments that test these ideas and explains the interplay between charge, potential, and the flow of electricity in different unit schemes.
- How unit dimensions and velocity connect electrostatic and electromagnetic quantities
- Historical experiments and their implications for the nature of light
- Techniques for measuring capacitance, resistance, and time in precision experiments
- Ways different unit systems are reconciled through physical constants
Ideal for readers of physics history, electricity, and the foundations of electromagnetism.
