      ether, in physics, a theoretical universal substance...

  2. 11 de jun. de 2024 · From the first speculations on the wave nature of light by Huygens through the progressively more refined theories of Young, Fresnel, and Maxwell, it was assumed that an underlying physical medium supports the transmission of light, in much the same way that air supports the transmission of sound.

  3. 26 de jun. de 2024 · Electric and magnetic observations date from antiquity. A Chinese Emperor in 2638 BC was said to use a compass to navigate his chariot through fog [ [i] ]. An embedded magnet was said to rotate a jade figurine to always point south, as in Figure 4.9.

  4. 18 de jun. de 2024 · Das Michelson-Morley-Experiment hatte zum Ziel, die Geschwindigkeit der Erde relativ zum Lichtäther auf ihrer Bahn um die Sonne nachzuweisen oder, anders ausgedrückt, die Geschwindigkeit des Äthers relativ zur Erde („Ätherwind“).

  5. 24 de jun. de 2024 · Aether-electromagnetic theory and the Casimir effect. In this study, we explore the impact of an additional dimension, as proposed in Kaluza-Klein’s theory, on the Casimir effect within the context of Lorentz invariance violation (LIV), which is represented by the aether field.

  6. Hace 1 día · In the 1820s and 1830s, Ampère founded electrodynamics as the science of mechanical forces associated with electric currents, and Faraday discovered electromagnetic induction. By the mid-19th century, Neumann, Weber, and others in Germany had established an electrical science that integrated precision measurements with a unified theory based on mathematical potential or forces between ...

  7. 1 de jul. de 2024 · There are several widely used undergraduate textbooks in electromagnetism, including David Griffiths ' Introduction to Electrodynamics as well as Electricity and Magnetism by Edward Purcell and David Morin. [4] .
