218 degrees Fahrenheit below zero. M. Pouillet was right and Fourier wrong. That was the undoubted temperature of the starry space. Such is, perhaps, that of the lunar continents, when the orb of night has lost by radiation all the heat which fifteen days of sun have poured into her.
It is a crown of 'glory, and that means a lustrousness of character imparted by radiation and reflection from the central light of the glory of God.
You will think of some way to take care of it. What I want to ask, sir, is when do we let go the bombs? I do not know much about radiation, but I can set those bombs like you want them." Rip was touched by the Planeteer's faith in his ability to solve the radiation problem. That was why being an officer in the Special Order Squadrons was so challenging.
"I've told you a thousand times that the radiation on this ship must have affected Ulf and Lyssa's germ plasm. Can't you understand that?" "I can understand it all right, but it does not change things. Ulf and Lyssa may have been human before they came here, but they were not when they landed. They were Lani, and their children were Lani." "But they were of human stock."
The entire sky, although lit up by stellar radiation, seemed pitch-black in comparison with the whiteness of these waters. Conseil couldn't believe his eyes, and he questioned me about the causes of this odd phenomenon. Luckily I was in a position to answer him. "That's called a milk sea," I told him, "a vast expanse of white waves often seen along the coasts of Amboina and in these waterways."
A purplish shade would else be produced; the yellow used is a colour complementary to that purple, and it absorbs just those blue and purple rays of the spectrum necessary to illuminate by radiation that purple, and vice versâ; both yellow and purple therefore disappear.
And while, from the enormous gravitative force of his parts to their common centre, the evolution of heat has been intense, the facilities of radiation have been relatively small. Hence the still-continued high temperature. Just that condition of the central body which is a necessary inference from the Nebular Hypothesis, we find actually existing in the Sun.
But as the body is constantly losing heat by radiation and conduction, it is evident that if the standard temperature be maintained, a certain amount of heat must be generated within the body to make up for the loss externally. The heat thus produced is known as animal or vital heat. This generation of heat is common to all living organisms.
Thus Curie pointed out that if the air inside a glass tube has been rendered radioactive by a solution of radium, the tube may be sealed up, and it will then be noted that the radiation of its walls diminishes with time, in accordance with an exponential law.
For instance, radiation being nothing but a flux of energy, we could, in order to establish photometric units, divide the normal spectrum into bands of a given width, and measure the power of each for the unit of radiating surface. But, notwithstanding some recent researches on this question, we cannot yet consider the distribution of energy in the spectrum as perfectly known.
