The End of Matter (1906)

>>The essay seems to be predicated on the mistaken notion at the time that the electron has no mass

Have you ever observed that an insulated copper conductor or a diode constantly conducting electrons in one direction would loose mass?

What is really funny is that eventually our understanding circled back and now the rest mass of particles is attributed to their interaction with the Higgs field, by effectively the same basic mechanism that Poincare-Lorentz-Abraham invented.

> The aether hypothesis was the topic of considerable debate throughout its history, as it required the existence of an invisible and infinite material with no interaction with physical objects. As the nature of light was explored, especially in the 19th century, the physical qualities required of an aether became increasingly contradictory. By the late 1800s, the existence of the aether was being questioned, although there was no physical theory to replace it.

The grandfather of the dark matter, seems.
