Page 377 - 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.
Page 75 - 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.
Page 115 - The immediate cause of the phenomena of heat then is motion, and the laws of its communication are precisely the same, as the laws of the communication of motion.
Page 450 - Look at the integrated energies of our world — the stored power of our coal-fields ; 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 vsTfTnhfwTfTS of tne whole.
Page 115 - ... the particles move round their own axes, and separate from each other, penetrating in right lines through space. Temperature may be conceived to depend upon the velocities of the vibrations; increase of capacity on the motion being performed in greater space; and the diminution of temperature, during the conversion of solids into fluids or gases, may be explained on the idea of the loss of vibratory motion, in consequence of the revolution of particles round their axes, at the moment when the...
Page 73 - Fahrenheit's ther69 mometer — could have been furnished by so inconsiderable a quantity of metallic dust, and this merely in consequence of a change in its capacity for heat...
Page 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.
Page 115 - ... and elastic fluids, besides the vibratory motion, which must be conceived greatest in the last, the particles have a motion round their own axes with different velocities, the particles of elastic fluids moving with the greatest quickness ;. and that in ethereal substances the particles move round their own axes, and separate from each other, penetrating in right lines through space.
Page 71 - Being engaged lately in superintending the boring of cannon in the workshops of the military arsenal at Munich, I was struck with the very considerable degree of Heat which a brass gun acquires in a short time in being bored, and with the still more intense Heat (much greater than that of boiling water, as I found by experiment) of the metallic chips separated from it by the borer.
Page 448 - Leaving out of account the eruptions of volcanoes, and the ebb and flow of the tides, every mechanical action on the earth's surface, every manifestation of power, organic and inorganic, vital and physical, is produced by the sun. His warmth keeps the sea liquid, and the atmosphere a gas, and all the storms which agitate both are blown by the mechanical force of the sun. He lifts the rivers and the glaciers up to the mountains, and thus the cataract and the avalanche shoot with an energy derived...
