Pāgina 505 - The sun's rays are the ultimate source of almost every motion which takes place on the surface of the earth. By its heat are produced all winds, and those disturbances in the electric equilibrium of the atmosphere which give rise to the phenomena of lightning, and probably also to those of terrestrial magnetism and the aurora.
Pāgina 74 - It is hardly necessary to add that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner the Heat was excited and communicated in these experiments, except it be MOTION.
Pāgina 73 - ... might be used in cooking victuals. But no circumstances could be imagined in which this method of procuring heat would be advantageous, for more heat might be obtained by using the fodder necessary for the support of a horse as fuel.
Pāgina 27 - BOILED ! It would be difficult to describe the surprise and astonishment expressed in the countenances of the bystanders, on seeing so large a quantity of cold water heated, and actually made to boil, without any fire.
Pāgina 516 - Look at the integrated energies of our world — the stored power of our coalfields ; our winds and rivers ; our fleets, armies, and guns. What are they ? They are all generated by a portion of the sun's energy, which does not amount to j, jyoWirjoth of the whole.
Pāgina 73 - From the results of these computations it appears that the quantity of heat produced equably, or in a continuous stream, if I may use the expression, by the friction of the blunt steel borer against the bottom of the hollow metallic cylinder, was greater than that produced in the combustion of nine wax candles, each three-quarters of an inch in diameter, all burning together with clear bright flames.
Pāgina 383 - DUKE'S PALACE. [Enter DUKE, CURIO, LORDS; MUSICIANS attending.] DUKE. If music be the food of love, play on, Give me excess of it; that, surfeiting, The appetite may sicken and so die.— That strain again;— it had a dying fall; O, it came o'er my ear like the sweet south, That breathes upon a bank of violets, Stealing and giving odour.— Enough; no more; 'Tis not so sweet now as it was before.
Pāgina 71 - From whence comes the Heat actually produced in the mechanical operation above mentioned ? Is it furnished by the metallic chips which are separated by the borer from the solid mass of metal ? If this were the case, then, according to the modern doctrines of latent Heat, and of caloric, the capacity for Heat...
Pāgina 69 - This difference is most observable in flame, where the smoke or thick vapour manifestly dilates and expands into flame. It is shown also in all boiling liquid, which manifestly swells, rises, and bubbles, and carries on the process of self-expansion, till it turns into a body far more extended and dilated than the liquid itself, namely, into vapour, smoke, or air.
Pāgina 476 - I had often, in the pride of half knowledge, smiled at the means frequently employed by gardeners, to protect tender plants from cold, as it appeared to me impossible, that a thin mat, or any such flimsy substance, could prevent them from attaining the temperature of the atmosphere, by which alone I thought them liable to be injured. But, when I had learned, that bodies on the surface of the earth become, during a still and serene night, colder than the atmosphere, by radiating their heat to the...
