In both cases the secret of the transmission of the vibrations or waves of vibratory energy may be summed up in the word "TRANSFORMATION." For instance: When we transmit electric vibrations over a fine wire or thread of carbon, the electric vibrations are transformed into light vibrations and manifest as "electric light."
You will find it occupied by a coke brazier, emitting large quantities of carbon monoxide, and an untidy gentleman in khaki, with a blue-and-white device upon his shoulder-straps, who is humped over a small black instrument, luxuriating in a "frowst" most indescribable. He is reading a back number of a rural Scottish newspaper which you never heard of.
The wireless transmitter, like that of the wire telephone, contains a sensitive diaphragm which your voice strikes and sets to vibrating. These vibrations compress and release a capsule of carbon granules which agitate and set in motion an electrical current in two magnets connecting with them.
So long as he walked with God, he was of importance for the historian; but as soon as he forsook God, and was consequently forsaken of His wisdom, he becomes as insignificant as an empty vessel which has once held sweet perfume, or a piece of carbon through which the electric current has ceased to flow. The sunbeam has left that peak, and shines on other summits. Never was there a sadder eclipse.
In wood, coal, oil, tallow, and spirits of wine; in everything in short that we call combustibles, because the name of combustion has been given to this marriage of oxygen with other bodies, hydrogen and carbon keep themselves shut up very discreetly and very quietly; like two children playing at hide-and- seek. You have sometimes played at hide-and-seek yourself, no doubt?
Now, if you burn a heap of wood in the open air, the carbon in the wood burns and only a pile of ashes remains. "Burning" means that the carbon in the wood unites with the oxygen gas in the air. If you cover the wood before you light it, so that only a little oxygen reaches it, much of the carbon is left, in the form of charcoal.
This idea being somewhat prevalent, and stoves being generally used in our school-houses, their influence upon health becomes a proper subject for consideration. Combustion, whether in a stove or fire-place, consists in a chemical union of the oxygen gas of the atmosphere with carbon, the combustible part of the wood or coal used for fuel.
Physicists teach us that the evolution of the primary elements hydrogen, oxygen, nitrogen, carbon, calcium, and the like takes place in a solar body as the body cools.
Supposing I add so much air to the flame as to cause it all to burn before those particles are set free, I shall not have this brightness; and I can do that in this way: If I place over the jet this wire-gauze cap, as you see, and then light the gas over it, it burns with a non-luminous flame, owing to its having plenty of air mixed with it before it burns; and if I raise the gauze, you see it does not burn below . There is plenty of carbon in the gas; but, because the atmosphere can get to it, and mix with it before it burns, you see how pale and blue the flame is.
I mean that For one thing, the temperature would be too harsh. It's way too cold on Mars to support life. Not to mention the atmosphere, which is mostly carbon dioxide." "Oh, my dear boy," smiled the face. "You don't know anything, do you?
