“Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had penetrative power to a degree hitherto unknown.”

—  Wilhelm Röntgen

The New Marvel in Photography (1896)
Context: Having discovered the existence of a new kind of rays, I of course began to investigate what they would do. … It soon appeared from tests that the rays had penetrative power to a degree hitherto unknown. They penetrated paper, wood, and cloth with ease; and the thickness of the substance made no perceptible difference, within reasonable limits. … The rays passed through all the metals tested, with a facility varying, roughly speaking, with the density of the metal. These phenomena I have discussed carefully in my report to the Würzburg society, and you will find all the technical results therein stated.

“I have satisfied myself that the [cosmic] rays are not generated by the formation of new matter in space, a process which would be like water running up a hill. Nor do they come to any appreciable amount from the stars. According to my investigations the sun emits a radiation of such penetrative power that it is virtually impossible to absorb it in lead or other substances…. This ray, which I call the primary solar ray, gives rise to a secondary radiation by impact against the cosmic dust scattered through space. It is the secondary radiation which now is commonly called the cosmic ray, and comes, of course, equally from all directions in space. [The article continues: The phenomena of radioactivity are not the result of forces within the radioactive substances but are caused by this ray emitted by the sun. If radium could be screened effectively against this ray it would cease to be radioactive, he said. ]”

Pearls of Wisdom

“When I close my eyes, a strange thought comes to my mind. Who am I, what is my existence, this question comes again and again in my mind, I start looking for answers to my questions, time starts passing through me, then somewhere a golden ray starts appearing, when I see that ray I feel relaxed, slowly my eyes open, when I start getting answers to my questions.”

“They dare'd not invade the palace while the globe shone, for the light-rays would have killed them.”

Zend explaining the Spawn of Dagon to Elak
Short fiction, The Spawn Of Dagon (1938)
Context: "They dare'd not invade the palace while the globe shone, for the light-rays would have killed them. … This island-continent would have gone down beneath the sea long ago if I hadn't pitted my magic and my science against that of the children of Dagon. They are masters of the earthquake, and Atlantis rests on none too solid a foundation. Their power is sufficient to sink Atlantis forever beneath the sea. But within that room" — Zend nodded toward the curtain that hid the sea-bred horrors — "in that room there is power far stronger than theirs. I have drawn strength from the stars, and the cosmic sources beyond the universe. You know nothing of my power. It is enough — more than enough — to keep Atlantis steady on its foundation, impregnable against the attacks of Dagon's breed. They have destroyed other lands before Atlantis."
