Strana 117 - All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
Strana 117 - Behold, God is great, and we know him not, neither can the number of his years be searched out. 27 For he maketh small the drops of water: they pour down rain according to the vapour thereof: 28 Which the clouds do drop and distil upon man abundantly.
Strana 163 - It seems easy to conceive, how, by this successive condensation from above, the spout appears to drop or descend from the cloud, though the materials of which it is composed are all the while ascending. "The condensation of the moisture contained in so great a quantity of warm air as may be supposed to rise in a short time in this prodigiously rapid whirl, is, perhaps, sufficient to form a great extent of cloud, though the spout should be over land, as those at Hatfield; and if the land happens not...
Strana 181 - ... all bodies to the earth, is the very Force which is the principal one concerned in flight, and without which flight would be impossible. It is curious how completely this has been forgotten in almost all human attempts to navigate the air. Birds are not lighter than the air, but immensely heavier. If they were lighter than the air they might float, but they could not fly. This is the difference between a bird and a balloon.
Strana 163 - Taste it, said he! I could not help tasting it, it ran into my mouth, nose, eyes and ears. Was it then fresh or salt? As fresh, said he, as ever I tasted spring water in my life.
Strana 41 - ... of temperature. In nearly all thermometers the temperature is measured by the expansion of some body, mercury, alcohol, or air being commonly used as the thermometric substance. The first thermometer was probably made by Galileo before 1597. It consisted of a glass bulb containing air, terminated below in a long glass tube which dipped into a vessel containing a colored fluid. The variations of volume of the enclosed air caused the fluid to rise or fall in the tube, the temperature being read...
Strana 194 - ... are so distant and deep and hot that its price to the consumer is greatly higher than at present, it is most probable that windmills or wind-motors in some form will again be in the ascendant, and that wind will do man's mechanical work, on land at least, in proportion comparable to its present doing of work at sea. Even now it is not utterly chimerical to think of wind superseding coal in some places for a very important part of its present duty — that of giving light. Indeed, now that we...
Strana 49 - ... winds, such as daily sea breezes and Monsoons, is differences in the heating of air above land and above sea. When land and sea are exposed to the same sun heat the temperature of the land rises much higher than the temperature of the sea, and it gives off heat much more quickly to the air overlying it. If the same amount of sun heat falls upon an equal area of land and water it raises the temperature of the former four or five times as much as that of the latter. On the other hand, the sea holds...
Strana 70 - Coriolis effect causes any txxly moving freely on or near the surface of the earth to be displaced to the right of its path in the northern hemisphere and to the left in the southern hemisphere.
Strana 49 - ... of the inclination of the earth's axis to the plane in which our globe makes its journey around the sun.
