"Platinum" Quotes from Famous Books



... not well-known that heat increases one degree for every seventy feet you descend into the earth? Which gives a fine idea of the central heat. All the matters which compose the globe are in a state of incandescence; even gold, platinum, and the hardest rocks are in a state of fusion. What would ...

... will. As every chemist knows, sulphuric acid and alcohol, when mingled together in a glass vessel, do not combine. They have an affinity for each other. All of the necessary elements for active combination are present in that glass, and yet they do not combine. But drop in a bit of platinum and instantly the whole mass is boiling with energy let loose. In a similar way, oftentimes, all the elements for decision and action are present in the mind, yet nothing happens. But a word or a little ...

... got back to the gold company. "From the earliest times, my friends, scientists have known of the existence of gold in sea-water. Together with other metals,—silver, platinum, and so on, there is a great amount of gold in sea-water. It is in tiny particles, not so big as the point of a needle. There it is,—but how shall it be got together? How shall it be extracted from the water? Aristotle tried to discover a method. He failed. ...

It was even worthy of The Watch. As soon as she ...

... living being, the protobion. To get this protobion the chemists summon a reagent known as a catalyser. The catalyser works its magic on the jelly mass. It sets up a wonderful reaction by its mere presence, without parting with any of its substance. Thus, if a bit of platinum which has this catalytic power is dropped into a vessel containing a mixture of oxygen and hydrogen, the two gases instantly unite and form water. A catalyser introduced in the primordial jelly liberates energy and gives the substance power to break up the various complex unstable ...

... I said, vaguely, bewildered by the glittering baubles by which I was confronted. What did Maude want? While I was gazing into the case, Mr. Garner opened a safe behind him, laying before me a large sapphire set with diamonds in a platinum brooch; a beautiful stone, in the depths of it gleaming a fire like a star in an arctic sky. I had not given Maude anything of value of late. Decidedly, this was of value; Mr. Garner named the price glibly; if Mrs. Paret didn't care for it, it might be brought back ...

I will make the flame dim, for the purpose of giving a little light only, and yet you will see that the heat which it can give to that platinum-wire, though far less than the heat it has itself, is able to raise the platinum-wire to a far higher state of effulgence. This flame has carbon in it; but I will take one that has no carbon in it. ...

While alcohol will not readily unite with oxygen under common conditions, if the alcohol is allowed to pass over a bit of platinum sponge the union readily occurs and acetic acid results.

Clarke has overcome this defect by so arranging his mechanism that the faintest contact in the primary instrument closes two platinum points in multiple arc with it, thus making a firm and positive contact, which is not disturbed by any jar on the primary contact. This gives the instruments a positive start for the series of operations, instead of the faint contact which would be given, for example, by the light and slowly ...

How Henry will admire it—and how mystified Adolph is! Tell him you bought it out of the money you saved on corned beef. How I shall enjoy seeing ...

In a gloomy forest it is frequently difficult to catch the muzzle sight, unless it is of some bright metal, such as silver or platinum; and a broad cut in the breech-sights, if shaped ...

... as in muscle and in plant, we find instances of that progressive diminution of response which is known as fatigue (fig. 69). The accompanying record shows this in platinum (fig. 70). It has been said that tin is practically indefatigable. We must, however, remember that this is a question of degree only. Nothing is absolutely indefatigable. The exhibition of fatigue depends on various conditions. Even in tin, then, I obtained the ...

It has already been proved that there is no necessity for using expensive salts of gold, silver or platinum in order to secure the most artistic prints; and, as a matter of fact, some of the finest art work in the photography of the past quarter of a century has been accomplished with the cheapest of materials, such ...

... whereby a metal may be drawn out to form a wire. Some metals, like cast iron, have absolutely no ductility. The metal which possesses this property to the highest degree, is platinum. Wires of this metal have been drawn out so fine that over 30,000 of them laid side by side would measure only one inch across, and a mile of such wire would weigh only a grain, or one seven-thousandth ...

... available for the variable-resistance element in telephone transmitters, carbon is by far the most suitable, and its use is well nigh universal. Sometimes one of the rarer metals, such as platinum or gold, is to be found in commercial transmitters as part of the resistance-varying device, but, even when this is so, it is always used in combination with carbon in some form or other. Most of the transmitters in use, however, ...

From the bottom there leads another fine tube, bent upwards, and then at right angles so as to be at the same level as the capillary branch. This tube bears a graduation. A loop of platinum wire passed under these tubes serves to suspend the vessel from the balance arm. The manner of cleansing, &c., is the same as in the ordinary form. The vessel is filled by placing the capillary in a vessel containing the liquid and gently aspirating. Care must be taken that no air bubbles ...

... that any State or any combination of States, less than world-wide, could be substantially self-sufficient in respect of all raw materials is untenable. Even the United States lacks (mentioning minerals only) nickel, cobalt, platinum, tin, diamonds.

Outside of minerals we lack jute, copra, flax fiber, raw silk, tea, coffee, ...

The idea that this film of bacteria oxidizes the alcohol beneath by merely condensing atmospheric oxygen in its interstices, after the manner of spongy platinum, has long been given up; but the explanation of the action as an incomplete combustion, depending on the peculiar respiration of these organisms—much as in the case of nitrifying and sulphur bacteria—is not clear, though the discovery that ...

... time every effort was made to bolster up credit. Endless were the attempts to find a substitute for gold. The chemists sought it in their laboratories and the mineralogists in the mountains and deserts. Platinum might have served, but it, too, had become a drug in the market through the discovery of immense deposits. Out of the twenty odd elements which had been rarer and more valuable than gold, such as uranium, gallium, etc., not one was found ...

... hygroscopic. An ethereal solution, carefully evaporated, deposits it in the form of crystals. Its empirical form is C23H40N2; it is probably volatile and is notable for its lack of oxygen. It differs from quinoidine in that it is inactive (?) and that in combination with platinum it retains less of this metal than does quinoidine. It differs from paricine in its proportion of hydrogen, and from berberine in containing more carbon. In the presence of sulphuric acid its solution assumes a yellow color, changing to wine-red and then to dark red. Naylor extracted ...
